{{warning box| The original protocol used by Let’s Encrypt for certificate issuance and management is called ACMEv1. In March of 2018 Letsencrypt introduced support for ACMEv2, a newer version of the protocol that matches what was finalized today as RFC 8555 328. They have been encouraging subscribers to move to the ACMEv2 protocol.
 +
 
 +
In March 2019 they announced an end of life plan for ACMEv1.
 +
 
 +
In November of 2019 they will stop allowing new account registrations through their ACMEv1 API endpoint. '''IMPORTANTLY''' Existing accounts will continue to function normally.
 +
 
 +
In June of 2020 they will stop allowing new domains to validate via ACMEv1.
 +
 
 +
Starting at the beginning of 2021 they will occasionally disable ACMEv1 issuance and renewal for periods of 24 hours, no more than once per month (OCSP service will not be affected). The intention is to induce client errors that might encourage subscribers to update to clients or configurations that use ACMEv2.
 +
 
 +
Renewal failures should be limited since new domain validations will already be disabled and we recommend renewing certificates 30 days before they expire.
 +
 
 +
In June of 2021 they will entirely disable ACMEv1 as a viable way to get a Let’s Encrypt certificate.}}

As of December 2015, the Letsencrypt service is in a public beta state.  They issue valid, trusted certificates, but the client code (and, to a lesser extent, the server code) is likely in a state of flux.  At least during the initial stages of the public beta, they're implementing rate-limiting, allowing no more than five certificates per domain in a rolling seven-day period.  This may make them unsuitable for users of dynamic DNS services.  The latest information about rate limiting should be posted on [https://letsencrypt.org/docs/rate-limits/ this page] of the letsencrypt.org documentation.  As of March 26, 2016, the rate limit has been increased to 20 certificates per domain per week.

If you're going to be testing things in ways that would involve requesting lots of certificates in a short period of time, you're encouraged to use the Letsencrypt staging CA for this purpose.  Certificates generated by this CA will not be trusted by your browser, and will appear to be issued by the "Fake LE Intermediate X1", but it will allow you to validate the toolchain and workflow.

At this time (January 2016), a contrib is under active development using the letsencrypt.sh script.  See [http://bugs.contribs.org/show_bug.cgi?id=8676 Bug 8276] and the [https://github.com/reetp/smeserver-letsencrypt/tree/smeserver-letsencrypt-0.1 GitHub page] for further information.
+
Multiple clients are available for the Letsencrypt services.  The official "certbot" client from letsencrypt.org is quite full-featured, but has a number of dependencies that it needs to install.  It also requires a newer version of Python than is included with a standard SME Server installation. Due to this complexity, and the lack of compatibility with SME 8.x, this document describes installation and use of ''[https://github.com/lukas2511/dehydrated dehydrated]'', an alternative client implemented as a BASH shell script.

Users running Windows XP and using either Internet Explorer or Google Chrome will experience certificate errors when visiting web sites with LetsEncrypt certificates.  Firefox on Windows XP does not have this problem.  This results from a broken SSL implementation in Windows XP.  If you need error-free SSL/TLS communications with users using Windows XP, you may need to use a different certificate authority.

==Installation of Dehydrated letsencrypt contrib==

Multiple clients are available for the Letsencrypt services.  The official client from letsencrypt.org is quite full-featured, but has a number of dependencies that it needs to install.  It also requires a newer version of Python than is included with a standard SME Server installation.  SME Server 9.0 and later, in the 64-bit versions, support the use of Software Collections, which allow installation of Python 2.7 alongside the default Python 2.6 installation.
+
John Crisp has prepared a contrib that installs the dehydrated script, creates the appropriate configuration files, and integrates with the SME templates system.  This is the simplest way to install dehydrated on your SME Server.
 +
<tabs container style="display: inline-block;"><tab name="For SME 10">
 +
  yum install smeserver-letsencrypt
  
−
Users of SME Server 8.x, or those who would prefer a more lightweight client, can use an alternative.  Letsencrypt.sh, documented below, is a shell script that requires no further dependencies that aren't installed by default on the SME Server.
+
You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.
  
−
=== Installation of Official Client ===
+
If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default.
−
For the installation of Letsencrypt, the initial generation of the certificates and periodically re-new the authority certificates, at minimum Python version 2.7 is required. By default SME Server comes with a lower version, but below instruction will enable you to install version 2.7 in a 'supported' way, next to the default SME Server Python version. The newly installed Python version 2.7 will then only be used (after initial installation) for the renewal of the certificates (periodically and mandatory every 3 months).
+
  db yum_repositories setprop smeaddons status enabled
−
   
+
signal-event yum-modify
−
Follow the instructions at [[Software_Collections]] and the python related wiki page specifically. You need to add the scl-repository for Python 2.7 that can be found [http://wiki.contribs.org/Scl#tab=Python27 '''here''']
 
  
−
To install Python 2.7:
+
</tab><tab name="For SME 9">
−
  yum install python27 --enablerepo=scl-python27
+
===Installation===
 +
  yum install smeserver-letsencrypt
 +
signal-event console-save
  
−
You can download the latest Letsencrypt code from their Github page either via GIT or as a ZIP file.
+
You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.
  
−
To download via GIT do:
+
If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default.
−
  yum install git
+
  db yum_repositories setprop smeaddons status enabled
−
  cd /opt
+
  signal-event yum-modify
−
git clone https://github.com/letsencrypt/letsencrypt.git
 
  
−
To download as a ZIP do:
+
===Updating===
−
  wget https://github.com/letsencrypt/letsencrypt/archive/master.zip -P /opt
+
Few reported issue when upgrading the contribs see [[Bugzilla:10286]] and [[Bugzilla:10097]]
−
unzip /opt/master.zip -d /opt && mv /opt/letsencrypt-master /opt/letsencrypt
 
−
rm -f /opt/master.zip
 
  
 +
A full update can be done as follow :
 +
yum update smeserver-letsencrypt dehydrated
 +
config setprop letsencrypt ACCEPT_TERMS yes
 +
signal-event console-save
 +
failure to do this might leave the contribution not working and your certificates not renewed.
 +
</tab>
 +
</tabs>
  
−
To use Let's Encrypt run:
+
==Configuration==
−
cd /opt/letsencrypt
+
There are several configuration database entries that need to be made in order to set up this contrib. Most of them tell the scripts which hostnames need to be part of your certificate.
−
service httpd-e-smith stop
 
−
scl enable python27 bash
 
−
  ./letsencrypt-auto certonly --standalone --email me@mydomain.co.uk -d test.firstdomain.co.uk -d seconddomain.co.uk -d www.seconddomain.co.uk
 
−
exit
 
  
−
Replacing email and domains as required.  You should include every hostname that is hosted on your SME server, along with any aliases you use (e.g., www.yourdomain.tld, mail.yourdomain.tld, yourdomain.tld, www.yourotherdomain.tld, etc.).  If it completes with no errors, it should tell you your certificate has been created.  To confirm, do:
+
=== Rush jobs ===
−
  ls -l /etc/letsencrypt/live/test.firstdomain.co.uk
+
For the test ('''adjust the domains and hosts'''):
 +
<tabs container style="display: inline-block;"><tab name="For SME 10">
 +
config setprop letsencrypt ACCEPT_TERMS yes status test
 +
# really fast job to enable the primary domain
 +
db domains setprop $(config get DomainName) letsencryptSSLcert enabled
 +
#foreach of your domains you want SSL do the following
 +
db domains setprop '''domain1.com''' letsencryptSSLcert enabled
 +
  #foreach of your hosts (subdomains) you want SSL do the following
 +
db hosts setprop '''www.domain1.com''' letsencryptSSLcert enabled
 +
signal-event smeserver-letsencrypt-update
 +
dehydrated -c
 +
</tab><tab name="For SME 9">
 +
config setprop letsencrypt ACCEPT_TERMS yes status test API 2
 +
#foreach of your domains you want SSL do the following
 +
db domains setprop '''domain1.com''' letsencryptSSLcert enabled
 +
#foreach of your hosts (subdomains) you want SSL do the following
 +
db hosts setprop '''www.domain1.com''' letsencryptSSLcert enabled
 +
  signal-event console-save
 +
  dehydrated -c
 +
</tab>
 +
</tabs>
 +
Check that the certificates are available ( your browser will still issue an error, but you can explore the content of the certificate to see that the Let's Encrypt test CA was used to sign your SSL certificate and that all your domains and hosts are in the "Certificate Subject Alt Name" property.
  
−
You should see something very similar to this:
+
For the production ('''adjust your email'''):
−
lrwxrwxrwx 1 root root 43 Dec 16 17:08 cert.pem -> ../../archive/test.firstdomain.co.uk/cert1.pem
+
<tabs container style="display: inline-block;"><tab name="For SME 10">

−
  lrwxrwxrwx 1 root root 48 Dec 16 17:08 fullchain.pem -> ../../archive/test.firstdomain.co.uk/fullchain1.pem
+
signal-event smeserver-letsencrypt-update
−
  lrwxrwxrwx 1 root root 46 Dec 16 17:08 privkey.pem -> ../../archive/test.firstdomain.co.uk/privkey1.pem

  dehydrated -c -x
 +
</tab><tab name="For SME 9">
 +
config setprop letsencrypt status enabled email '''admin@domain1.com'''
 +
  signal-event console-save
 +
  dehydrated -c -x
 +
</tab>
 +
</tabs>
  
−
If you do not see these files, '''stop'''.  Troubleshoot the problem before proceeding.  If you continue, you will break your web server any anything else that depends on SSL.  If you do see these files, go ahead and configure SME with the certificates generated:
+
===Step by step configuration===
  
−
  config setprop modSSL crt /etc/letsencrypt/live/test.firstdomain.co.uk/cert.pem
+
====Hosts and domains for the certificate====
−
config setprop modSSL key /etc/letsencrypt/live/test.firstdomain.co.uk/privkey.pem
+
This contrib will obtain a single certificate from Let's Encrypt. The certificate will include all the domains and hostnames that:
−
config setprop modSSL CertificateChainFile /etc/letsencrypt/live/test.firstdomain.co.uk/chain.pem
+
* Are configured on your SME Server (e.g., through the Server Manager), and
−
signal-event domain-modify; signal-event email-update; signal-event ibay-modify
+
* Are configured to use Let's Encrypt.
−
service httpd-e-smith start
 
  
−
{{Note box|We need to see if setting the above db variables disturbs other SME Server default functionality and contribs that work with certificates such as VPN solutions.}}
+
For example, your SME Server may contain the following domains and hostnames:
  
−
Once you've obtained your certificate and configured your server, test your server with a tool like [https://www.ssllabs.com/ssltest/ SSLLabs.com] to make sure it's working properly.
+
* domain1.com
 +
** www.domain1.com
 +
** mail.domain1.com
 +
** ftp.domain1.com
  
−
=== Installation of Letsencrypt.sh ===
+
* domain2.com
−
Letsencrypt.sh is a lightweight alternative ACME client which will allow you to retrieve certificates from the Letsencrypt servers without needing to install any additional software on your server, other than git to download and install it.  Begin by installing git:
+
** www.domain2.com
−
  yum install git
+
** mail.domain2.com
 +
For each DOMAIN that you want to be included in the certificate, run this command:
 +
  db domains setprop $DOMAIN letsencryptSSLcert enabled
  
−
Then download the letsencrypt.sh client:
+
Using the above example, one invocation of the command would look like this:
−
  cd /etc
+
  db domains setprop domain1.com  letsencryptSSLcert enabled
−
git clone https://github.com/lukas2511/letsencrypt.sh
 
−
  mv letsencrypt.sh/letsencrypt.sh /usr/local/bin/
 
  
−
You'll need to create two configuration files for letsencrypt.sh.
+
For each HOSTNAME that you want to be included in the certificate, run this command:
−
  cd letsencrypt.sh
+
  db hosts setprop $HOSTNAME letsencryptSSLcert enabled
−
mkdir -p /home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
 
−
nano -w domains.txt
 
  
−
In this file, you'll list every hostname that you want your certificate to cover, all on one line.  It will look like this:
+
Using the above example, one invocation of the command would look like this:
−
  domain1.com www.domain1.com mail.domain1.com domain2.net www.domain2.net domain3.org ftp.domain3.org
+
  db hosts setprop www.domain1.com letsencryptSSLcert enabled
−
Ctrl-X to exit, Y to save.
 
  
−
Second, you'll need to create the configuration file:
+
You can obtain a certificate for either of the following: all domains, all hostnames, or all domains AND hostnames. Only set one of the following.
−
nano -w config.sh
 
  
−
It should look like this:
+
  config setprop letsencrypt configure domains
−
  #!/bin/bash
 
−
# config.sh
 
−
 
−
WELLKNOWN="/home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge"
 
−
HOOK="/usr/local/bin/letsencrypt-hook.sh"
 
−
# E-mail to use during the registration (default: <unset>)
 
−
CONTACT_EMAIL="admin@yourdomain.com"
 
−
Ctrl-X to exit, Y to save.
 
  
−
You'll need to create a custom "hook" script to set the config database up properly, and to trigger reloads of your system services when a certificate is issued or renewed.
+
config setprop letsencrypt configure hosts
−
nano /usr/local/bin/letsencrypt-hook.sh
 
  
−
Its contents should look like this:
+
  config setprop letsencrypt configure all
−
  #!/bin/bash
 
−
 
−
if [ $1 = "deploy_cert" ]; then
 
−
  KEY=$3
 
−
  CERT=$4
 
−
  CHAIN=${5/fullchain.pem/chain.pem}
 
−
  /sbin/e-smith/db configuration setprop modSSL key $KEY
 
−
  /sbin/e-smith/db configuration setprop modSSL crt $CERT
 
−
  /sbin/e-smith/db configuration setprop modSSL CertificateChainFile $CHAIN
 
−
  /sbin/e-smith/signal-event domain-modify
 
−
  /sbin/e-smith/signal-event email-update
 
−
  /sbin/e-smith/signal-event ibay-modify
 
−
fi
 
−
Ctrl-X to exit, Y to save.  Then make it executable:
 
−
chmod +x /usr/local/bin/letsencrypt-hook.sh
 
  
−
You'll also need to create a custom template fragment for Apache:
+
To use individually enabled hosts or domains leave the default none.
−
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf
 
−
nano -w /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/VirtualHosts40ACME
 
  
−
The contents of that file should look like:
+
  config setprop letsencrypt configure none
−
  # Alias for letsencrypt
 
−
Alias /.well-known/acme-challenge /home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
 
−
Again, Ctrl-X to exit, Y to save.
 
  
−
Expand the template and restart apache:
 
−
expand-template /etc/httpd/conf/httpd.conf
 
−
service httpd-e-smith restart
 
  
−
Now you're ready to run letsencrypt.sh and get your certificate.
+
With the system configuration described above, setting this to "domains" will obtain a certificate covering domain1.com and domain2.com, but not www.domain1.com, etc.  Setting it to "hosts" will obtain a certificate covering www.domain1.com, mail.domain1.com, ftp.domain1.com, etc., but not domain1.com or domain2.com.  Setting this property to "all" will include all domain names and hostnames in the certificate. '''See [[Letsencrypt/Troubleshooting#Some_challenges_complete_successfully_but_some_hostnames_fail|NOTE]] before setting this to "all".'''
−
  letsencrypt.sh -c
 
  
−
The script will run for a moment and should report success.  If it does, look in /etc/letsencrypt.sh/certs/YOURDOMAIN and see if you have your files there.  You should see a number of .pem files, at least one .csr file, and five symbolic links (chain.pem, cert.csr, cert.pem, fullchain.pem, and privkey.pem).  If you do, congratulations!  You've successfully obtained your certificate.  The hook script should have also configured your server to use the new certificate.  To make sure, run
+
==== Enable test mode ====
−
  config show modSSL
+
After installing and configuring all the domains and hosts, the next step is to use test mode, which is enabled by default. This will obtain certificates from the staging server.  The rate limits discussed in the introduction won't apply, so any errors or other issues won't prevent you from obtaining your production certificate.  Enable test mode using this command:
−
and make sure there are values set for crt, key, and CertificateChainFile.
+
  config setprop letsencrypt status test
 +
signal-event console-save
  
−
As above, once you've obtained your certificate and configured your server, test your server with a tool like [https://www.ssllabs.com/ssltest/ SSLLabs.com] to make sure it's working properly.
+
You can now run dehydrated for the first time, and make sure it's able to connect to the Let's Encrypt servers, validate the hostnames you're requesting, and issue certificates. To do this, run
 +
dehydrated -c
  
−
== Troubleshooting ==
+
If it prints only "# INFO: Using main config file /etc/dehydrated/config" and returns you to the shell prompt, see [[Bugzilla:10300]].
  
−
Errors in the certificate files may prevent Apache and some other services from starting. If you previously had custom settings for modSSL, revert those with:
+
{{Note box|Solution for error "Malformed account ID in KeyID header URL" using API 2, for contrib versions 0.6.13 or older See [[Bugzilla:10828]] or update to latest contrib}}
−
config setprop modSSL crt (old value)
 
−
config setprop modSSL key (old value)
 
−
config setprop modSSL CertificateChainFile (old value--if this property was empty, delete it using the command line below)
 
  
−
If you did not have custom settings for modSSL, remove your changes with:
+
If this runs without errors, try to connect to your server-manager page. You should see an error that the security certificate wasn't issued by a trusted certification authority; this is perfectly normal. However, there should be a certificate, it should include all the hostnames you wanted included, and it should be valid for the next ninety days. If this was successful, proceed to production.
−
  config delprop modSSL crt
 
−
  config delprop modSSL key
 
−
  config delprop modSSL CertificateChainFile
 
  
−
Once you've made these changes, do:
+
====Enable Production Mode====
−
signal-event post-upgrade
+
Once you've successfully tested your installation, set it to production mode using these commands:
−
signal-event reboot
 
  
−
== Renewal of the certificates ==
+
config setprop letsencrypt status enabled
−
As part of the security of Letsencrypt the certificates must be renewed every 3 months. The process will differ depending on whether you're using the official client or letsencrypt.sh.
+
signal-event console-save
 +
 +
Then obtain a new certificate from the Let's Encrypt production server:
 +
  dehydrated -c -x
  
−

The -x flag here is needed to force dehydrated to obtain a new certificate, even though you have an existing certificate that's valid for more than 30 days.
−
The following script will automatically renew your certificate.  Save it in a convenient place, for example, /opt/letsencrypt-renew.sh, and make sure to make it executable (chmod +x).
 
  
−
#!/bin/bash
+
If this command succeeded, congratulations!  You've successfully obtained a valid, trusted TLS certificate, which will automatically renew itself in perpetuity.  
−
/sbin/service httpd-e-smith stop

+
Once you've obtained your certificate and configured your server, test your server with a tool like [https://www.ssllabs.com/ssltest/ SSLLabs.com] to make sure it's working properly.
−
# scl enable python27 '/opt/letsencrypt-renew.sh'
 
  
−
You may want to set this up as a cron job to run every two months, to make sure your certificate doesn't expire. Please see '''[[Crontab_Manager]]''' contrib for an easy way to achieve this.  Or, to set this from the command line, do the following:
+
====Archive old certificates====
  
−
mkdir -p /etc/e-smith/templates-custom/etc/crontab
+
A new function lets you cleanup old and archive old certificates.
−
nano /etc/e-smith/templates-custom/etc/crontab/sslrenew
 
  
−
The following example will run the renewal script at 22:48 on the third of every other month (Jan, Mar, May, etc.):
+
dehydrated --cleanup (-gc)
  
−
48 22 3 */2 * root scl enable python27 '/opt/letsencrypt-renew.sh'

−
The time and day of the month can be chosen at your discretion--I've deliberately chosen a time that isn't at the top or bottom of the hour, or on the first of the month, in the hope of reducing load on letsencrypt's servers.  Since the certificates are good for 90 days, this will renew your certificate in plenty of time.
 
−
 
 
−
=== Using Letsencrypt.sh ===
 
−
When run, the Letsencrypt.sh script will check your existing certificate to see how long it's valid.  If it has less than 30 days' lifetime remaining (by default; this can be changed by setting RENEW_DAYS in config.sh to something other than 30), the script will renew your certificates.  If more than 30 days remain, the script will exit without further action.  All that's necessary is to run letsencrypt.sh daily:
 
−
nano -w /etc/cron.daily/call-letsencrypt.sh
 
−
 
 
−
Enter the following in this file:
 
−
#!/bin/bash
 
−
/usr/local/bin/letsencrypt.sh -c
 
−
Ctrl-X to exit, Y to save.  Then make it executable:
 
−
chmod +x /etc/cron.daily/call-letsencrypt.sh
 
−
 
 
−
== Backup ==
 
−
Your certificate, private key, and other important information are stored in /etc/letsencrypt, which is not included in the standard SME Server backup routines.  Make sure to add this directory to your backups.  See, e.g., [[Backup with dar#Adding files and directories|Backup with dar]] if you're using the workstation backup feature.
 
−
 
 
−
== Creating certificates for internal servers ==
 
−
You may have one or more internal servers on your network for which you want or need trusted TLS certificates, but which aren't directly accessible from the outside.  The Letsencrypt service can handle this too, although the process isn't quite as simple as shown above.
 
−
 
 
−
Assumptions:
 
−
* You've followed the instructions above to install the Letsencrypt client, and it's working
 
−
* The hostname for which you need a certificate resolves, from the outside, to your SME Server.  For example, you've registered yourdomain.tld, and a DNS record for *.yourdomain.tld points to your SME Server.  You want to create a certificate for privateserver.yourdomain.tld
 
−
* Port 80 on your SME Server is open to the Internet--you aren't behind a firewall, or some ISP filtering, that would block it.
 
−
 
 
−
You can either create the certificate on your SME Server, and then copy it to the internal server using whatever means that server provides; or (if the internal server is able to run the Letsencrypt client) you can generate the certificate on the internal server.
 
  
−
=== Generate the certificate on the SME Server ===
+
== Advanced Topics ==
−
You could simply follow the instructions above, using the FQDN of your internal server.  However, those instructions require that you take down your web server briefly.  If you were generating a new certificate for the SME Server, you'd need to do this anyway, so that the web server would load the new certificate.  If you're generating a certificate for a different internal server, though, you may not want (and you do not need) to take down your SME Server's web server.
+
see [[Letsencrypt/Advanced]]
  
−
Follow the instructions above to create the certificate, but replace the letsencrypt command line with:
 
−
./letsencrypt-auto certonly --webroot --webroot-path /home/e-smith/files/ibays/Primary/html \
 
−
  --email admin@yourdomain.tld -d privateserver.yourdomain.tld
 
  
−
The Letsencrypt client will run and place the certificate files in /etc/letsencrypt/live/privateserver.yourdomain.tld/ on your SME Server.  You can then copy them to your internal server and install them using whatever mechanism that server provides.  This will not alter the configuration of your SME Server.
+
== Uninstall ==
−
 
+
  yum remove {{#var:smecontribname}} {{#var:contribname}}
−
Once the certificate files are created, installing them on the internal server can be automated.  One possible way to do this is to first ensure that the root user on your SME server has an [[SSH Public-Private Keys|SSH public key]] generated, that key does not have a passphrase assigned, and that key is trusted by the root user on your internal server.  Then, you can add the following to your renewal script:
+
== Bugs ==

Please raise bugs under the SME-Contribs section in [http://bugs.contribs.org/enter_bug.cgi bugzilla]
−
/opt/letsencrypt/letsencrypt-auto certonly --renew-by-default --webroot \
+
and select the smeserver-letsencrypt component or use {{BugzillaFileBug|product=SME%20Contribs|component=smeserver-letsencrypt|title=this link}}
−
  --webroot-path /home/e-smith/files/ibays/Primary/html --email admin@yourdomain.tld \
 
−
  -d privateserver.yourdomain.tld
 
−
 
−
export CERTDIR="/etc/letsencrypt/live/privateserver.yourdomain.tld"
 
−
scp $CERTDIR/cert.pem root@privateserver:/etc/pki/tls/certs/privateserver.yourdomain.tld.crt
 
−
  scp $CERTDIR/privkey.pem root@privateserver:/etc/pki/tls/private/privateserver.yourdomain.tld.key
 
−
  scp $CERTDIR/chain.pem root@privateserver:/etc/pki/tls/certs/server-chain.crt
 
−
ssh root@privateserver /sbin/service httpd restart
 
−
 
 
−
You will, of course, need to modify the paths on the internal server to be consistent with where that server expects the certificate files to be; the paths above are applicable to a CentOS-based server.
 
−
 
 
−
=== Generate the certificate on the internal server ===
 
−
If the internal server is Unix-y and otherwise meets the requirements for the Letsencrypt client, you can run the client on the internal server using manual domain authentication.  This will require you to create a small file on your SME Server, which you can delete once the certificate is created.
 
−
 
 
−
The letsencrypt command would look like:
 
−
./letsencrypt-auto certonly --manual --email admin@yourdomain.tld -d privateserver.yourdomain.tld
 
−
 
 
−
When the Letsencrypt client runs, it will show you a challenge like the following, with different random strings:
 
−
Make sure your web server displays the following content at
 
−
http://privateserver.yourdomain.tld/.well-known/acme-challenge/U8AGPrh8wTM9wYpaOGUmfihZezzoLrCAhspJYeO-lsc before continuing:
 
−
 
−
U8AGPrh8wTM9wYpaOGUmfihZezzoLrCAhspJYeO-lsc.oYz0Q5G7t8oAAhKBGu6Y9InuE1eP2CRhR-RtUVXvloc
 
  
−
At this point, on your SME Server, you'll need to create that file:
+
{{#bugzilla:columns=id,product,version,status,summary |sort=id |order=desc |component=smeserver-letsencrypt |disablecache=1|noresultsmessage="No open bugs found."}}
−
# mkdir -p /home/e-smith/files/ibays/Primary/html/.well-known/acme-challenge
 
−
# echo U8AGPrh8wTM9wYpaOGUmfihZezzoLrCAhspJYeO-lsc.oYz0Q5G7t8oAAhKBGu6Y9InuE1eP2CRhR-RtUVXvloc > /home/e-smith/files/primary/html/.well-known/acme-challenge/U8AGPrh8wTM9wYpaOGUmfihZezzoLrCAhspJYeO-lsc
 
  
−
Then press the Enter key on your internal server.  As of this writing (10 Dec 2015), the client has a bug which reports "Self-verify of challenge failed", but it will create the certificates anyway (and it will correctly tell you that they're created).  Once the client finishes and tells you the certificates are created, you can delete the nonce from your SME Server:
+
== Changelog ==
−
# rm /home/e-smith/files/primary/html/.well-known/acme-challenge/U8AGPrh8wTM9wYpaOGUmfihZezzoLrCAhspJYeO-lsc
+
Only released version in smecontrib are listed here.
  
−
The certificate files will be in /etc/letsencrypt/live/privateserver.yourdomain.tld/ on your internal server.

Description

Warning.png Warning:
The original protocol used by Let’s Encrypt for certificate issuance and management is called ACMEv1. In March of 2018 Letsencrypt introduced support for ACMEv2, a newer version of the protocol that matches what was finalized today as RFC 8555 328. They have been encouraging subscribers to move to the ACMEv2 protocol.

In March 2019 they announced an end of life plan for ACMEv1.

In November of 2019 they will stop allowing new account registrations through their ACMEv1 API endpoint. IMPORTANTLY Existing accounts will continue to function normally.

In June of 2020 they will stop allowing new domains to validate via ACMEv1.

Starting at the beginning of 2021 they will occasionally disable ACMEv1 issuance and renewal for periods of 24 hours, no more than once per month (OCSP service will not be affected). The intention is to induce client errors that might encourage subscribers to update to clients or configurations that use ACMEv2.

Renewal failures should be limited since new domain validations will already be disabled and we recommend renewing certificates 30 days before they expire.

In June of 2021 they will entirely disable ACMEv1 as a viable way to get a Let’s Encrypt certificate.


Let’s Encrypt is a new Certificate Authority: It’s free, automated, and open. Its main purpose is to allow people to encrypt their internet traffic at no cost, easily, and automatically. The certs delivered must be renewed every 3 months.

As of December 2015, the Letsencrypt service is in a public beta state. They issue valid, trusted certificates, but the client code (and, to a lesser extent, the server code) is likely in a state of flux. At least during the initial stages of the public beta, they're implementing rate-limiting, allowing no more than five certificates per domain in a rolling seven-day period. This may make them unsuitable for users of dynamic DNS services. The latest information about rate limiting should be posted on this page of the letsencrypt.org documentation. As of March 26, 2016, the rate limit has been increased to 20 certificates per domain per week.

If you're going to be testing things in ways that would involve requesting lots of certificates in a short period of time, you're encouraged to use the Letsencrypt staging CA for this purpose. Certificates generated by this CA will not be trusted by your browser, and will appear to be issued by the "Fake LE Intermediate X1", but it will allow you to validate the toolchain and workflow.

The current status of the Letsencrypt services can be found on their status page.

Multiple clients are available for the Letsencrypt services. The official "certbot" client from letsencrypt.org is quite full-featured, but has a number of dependencies that it needs to install. It also requires a newer version of Python than is included with a standard SME Server installation. Due to this complexity, and the lack of compatibility with SME 8.x, this document describes installation and use of dehydrated, an alternative client implemented as a BASH shell script.

Prerequisites

The Letsencrypt client and server interact to confirm that the person requesting a certificate for a hostname actually controls that host. For this reason, there are some prerequisites for your configuration. For example, if you're trying to obtain a certificate for www.example.com, the following conditions must be met:

  • www.example.com is a valid domain name--the domain has been registered, and DNS records are published for it.
  • www.example.com resolves to your SME Server--published DNS records give the external IP address of your SME Server when queried for www.example.com.
  • Your SME Server is connected to the Internet, and is able to make outbound connections on ports 80 and 443.
  • Port 80 on your SME Server is open to the Internet (i.e., the Internet can reach your server on port 80)--you aren't behind a firewall, or some ISP filtering, that would block it. If you've made SSL mandatory for the Primary ibay, port 443 must also be open.

Letsencrypt will issue certificates that include multiple hostnames (for example, www.example.com, example.com, and mail.example.com), all of which would be part of the request. All of the conditions above must be true for all of the hostnames you want to include in the certificate.

Make sure you've got this all set up correctly before continuing.

Preparation

Before you begin installation, check to see if you or an installed contrib have configured any custom values for your TLS/SSL certificate: 

# config show modSSL

By default it would show: 

modSSL=service
   TCPPort=443
   access=public
   status=enabled

If this shows any values for crt, key, or CertificateChainFile, make a note of them. If you encounter an issue with the certificate files generated by Letsencrypt, you'll then be able to revert your changes. To make a 'backup' of your existing key and properties you can issue: 

config show modSSL > "/root/db_configuration_modSSL_backup_$(date +%Y%m%d_%H%M%S)"

Installation of Dehydrated letsencrypt contrib

John Crisp has prepared a contrib that installs the dehydrated script, creates the appropriate configuration files, and integrates with the SME templates system. This is the simplest way to install dehydrated on your SME Server. 

yum install smeserver-letsencrypt

You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.

If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default. 

db yum_repositories setprop smeaddons status enabled
signal-event yum-modify

Installation

yum install smeserver-letsencrypt
signal-event console-save

You will then need to configure the domains and hosts for which you want to ask a certificate. See the following Configuration section.

If your smeaddons repo has been disabled add --enablerepo=smeaddons and reenable it, as it should be by default. 

db yum_repositories setprop smeaddons status enabled
signal-event yum-modify

Updating

Few reported issue when upgrading the contribs see Bugzilla:10286 and Bugzilla:10097

A full update can be done as follow : 

yum update smeserver-letsencrypt dehydrated
config setprop letsencrypt ACCEPT_TERMS yes
signal-event console-save

failure to do this might leave the contribution not working and your certificates not renewed.

Configuration

There are several configuration database entries that need to be made in order to set up this contrib. Most of them tell the scripts which hostnames need to be part of your certificate.

Rush jobs

For the test (adjust the domains and hosts): 

config setprop letsencrypt ACCEPT_TERMS yes status test
# really fast job to enable the primary domain
db domains setprop $(config get DomainName) letsencryptSSLcert enabled
#foreach of your domains you want SSL do the following
db domains setprop domain1.com letsencryptSSLcert enabled
#foreach of your hosts (subdomains) you want SSL do the following
db hosts setprop www.domain1.com letsencryptSSLcert enabled
signal-event smeserver-letsencrypt-update
dehydrated -c

config setprop letsencrypt ACCEPT_TERMS yes status test API 2
#foreach of your domains you want SSL do the following
db domains setprop domain1.com letsencryptSSLcert enabled
#foreach of your hosts (subdomains) you want SSL do the following
db hosts setprop www.domain1.com letsencryptSSLcert enabled
signal-event console-save
dehydrated -c

Check that the certificates are available ( your browser will still issue an error, but you can explore the content of the certificate to see that the Let's Encrypt test CA was used to sign your SSL certificate and that all your domains and hosts are in the "Certificate Subject Alt Name" property.

For the production (adjust your email): 

config setprop letsencrypt status enabled email admin@$(config get DomainName)
signal-event smeserver-letsencrypt-update
dehydrated -c -x

config setprop letsencrypt status enabled email admin@domain1.com
signal-event console-save
dehydrated -c -x

Step by step configuration

Hosts and domains for the certificate

This contrib will obtain a single certificate from Let's Encrypt. The certificate will include all the domains and hostnames that:

  • Are configured on your SME Server (e.g., through the Server Manager), and
  • Are configured to use Let's Encrypt.

For example, your SME Server may contain the following domains and hostnames:

  • domain1.com
    • www.domain1.com
    • mail.domain1.com
    • ftp.domain1.com
  • domain2.com
    • www.domain2.com
    • mail.domain2.com

For each DOMAIN that you want to be included in the certificate, run this command: 

db domains setprop $DOMAIN letsencryptSSLcert enabled

Using the above example, one invocation of the command would look like this: 

db domains setprop domain1.com  letsencryptSSLcert enabled

For each HOSTNAME that you want to be included in the certificate, run this command: 

db hosts setprop $HOSTNAME letsencryptSSLcert enabled

Using the above example, one invocation of the command would look like this: 

db hosts setprop www.domain1.com letsencryptSSLcert enabled

You can obtain a certificate for either of the following: all domains, all hostnames, or all domains AND hostnames. Only set one of the following. 

config setprop letsencrypt configure domains

config setprop letsencrypt configure hosts

config setprop letsencrypt configure all

To use individually enabled hosts or domains leave the default none. 

config setprop letsencrypt configure none


With the system configuration described above, setting this to "domains" will obtain a certificate covering domain1.com and domain2.com, but not www.domain1.com, etc. Setting it to "hosts" will obtain a certificate covering www.domain1.com, mail.domain1.com, ftp.domain1.com, etc., but not domain1.com or domain2.com. Setting this property to "all" will include all domain names and hostnames in the certificate. See NOTE before setting this to "all".

Enable test mode

After installing and configuring all the domains and hosts, the next step is to use test mode, which is enabled by default. This will obtain certificates from the staging server. The rate limits discussed in the introduction won't apply, so any errors or other issues won't prevent you from obtaining your production certificate. Enable test mode using this command: 

config setprop letsencrypt status test
signal-event console-save

You can now run dehydrated for the first time, and make sure it's able to connect to the Let's Encrypt servers, validate the hostnames you're requesting, and issue certificates. To do this, run 

dehydrated -c

If it prints only "# INFO: Using main config file /etc/dehydrated/config" and returns you to the shell prompt, see Bugzilla:10300.


Important.png Note:
Solution for error "Malformed account ID in KeyID header URL" using API 2, for contrib versions 0.6.13 or older See Bugzilla:10828 or update to latest contrib


If this runs without errors, try to connect to your server-manager page. You should see an error that the security certificate wasn't issued by a trusted certification authority; this is perfectly normal. However, there should be a certificate, it should include all the hostnames you wanted included, and it should be valid for the next ninety days. If this was successful, proceed to production.

Enable Production Mode

Once you've successfully tested your installation, set it to production mode using these commands: 

config setprop letsencrypt status enabled
signal-event console-save

Then obtain a new certificate from the Let's Encrypt production server: 

dehydrated -c -x

The -x flag here is needed to force dehydrated to obtain a new certificate, even though you have an existing certificate that's valid for more than 30 days.

If this command succeeded, congratulations! You've successfully obtained a valid, trusted TLS certificate, which will automatically renew itself in perpetuity.

Once you've obtained your certificate and configured your server, test your server with a tool like SSLLabs.com to make sure it's working properly.

Archive old certificates

A new function lets you cleanup old and archive old certificates. 

dehydrated --cleanup (-gc)
