SME on CentOS 6
SME on CentOS 6
These are some notes on my attempts at installing SME on CentOS 6.
There are two paths that I can see to testing this:
1. Install CentOS 6 Minimal and try to add the equivalent 6 packages and see what is missing.
2. Install CentOS 6 Minimal and then try to add existing SME v8 (el5) packages
I decided to try Route 1 first.
I did the following using a Virtualbox VM for expediency allowing me to revert changes easily if I needed too.
Installing CentOS 6 minimal
First a few notes on CentOS 6 minimal, which is a bare bones install with very little on board. You can download a copy from one of the CentOS mirrors here
- As per above note, only use Virtual Machine for testing purposes. A good free VM package van be obtained here
- You might want to note down as much as possible so you yourself and others can reproduce the actions
- Don't use yum with the '-y' flag (install/upgrade without further user interaction) when using the yum install/upgrade commands. (beware copy/paste yum commands)
- you might want to note down all packages listed by yum to be installed/upgraded AND their dependencies
- When you are using 64-bit, please add '--exlcude=*86' at the end of the yum command line. This will prevent i386/i686 packages to be installed as 'required' dependencies
- Make regular snapshots of your Virtual Machine and describe them specifically. At least when you've reached an important milestone for yourself
Enable networking
Each boot you have to start the network etc etc. I decided it was better with the minimal install and touch as little as possible - if I could then get SME packages installed I could then use that to configure networking later.
To start the networking
./etc/sysconfig/network-scripts/ifup-eth eth0
or
dhclient eth0
or if you want to assign a IP address yourself.
ifconfig eth0 192.168.1.2 echo "nameserver 192.168.1.254" >> /etc/resolv.conf route add default gw 192.168.1.254 eth0
To make your changes permanent you will need to edit the configuration file to make it active on boot. There is only the vi text editor, you can also install nano.
yum install nano nano /etc/sysconfig/network-scripts/ifcfg-eth0 and set ONBOOT=”YES”
Enable SSH
On first run make sure we have ssh installed so we can use a terminal to login - much easier for copy and pasting stuff :
yum install open-ssh*
To get to the sshd service you will need this on each boot :
service iptables stop service sshd start
SME Server specific/required packages
To get a list of all specific SME Server packages you can run:
rpm -qa | grep 'smeserver\|e-smith'| sed -e 's/-[0-9].*//'|sort > smeserver-packages.txt
SME Server specific/required perl packages
I decided to attack perl first as the SME stuff is written in it.
Here is a list of perl files from v8 and their equivalent in CentOS 6 if available....
To get a list of the file names in v8 either do (all file starting with the string 'perl'):
rpm -qa --qf '%{NAME}\n' name=perl\*
(Thanks Shad !)
or as per suggestion on the lists (All files containing the string 'perl')
rpm -qa | grep perl | sed -e 's/-[0-9].*//'
(Thanks Gordon !)
To get a alphabetically sorted list (which is easier to compare lists) add '|sort' to the commands above.
rpm -qa --qf '%{NAME}\n' name=perl\*|sort
rpm -qa | grep perl | sed -e 's/-[0-9].*//'|sort
To export the list to a plain text file you could do:
rpm -qa | grep perl | sed -e 's/-[0-9].*//'|sort > perl-list.txt
(Thanks HF !)
This is the output of the non-GREP variant:
perl-Digest-SHA Y perl Y perl-Archive-Tar Y perl-Authen-PAM ****** perl-Authen-SASL Y perl-BSD-Resource ****** perl-CGI-FormMagick ****** perl-CGI-Persistent ****** perl-Class-ParamParser ****** perl-Clone Y perl-Compress-Raw-Bzip2 Y perl-Compress-Raw-Zlib Y perl-Compress-Zlib Y perl-Convert-ASN1 Y perl-Convert-BinHex Y perl-Convert-TNEF ****** perl-Crypt-Cracklib ****** perl-Crypt-OpenSSL-Bignum Y perl-Crypt-OpenSSL-Random Y perl-Crypt-OpenSSL-RSA Y perl-DateManip Y perl-DBD-MySQL Y perl-DBI Y perl-Digest-HMAC Y perl-Digest-SHA1 Y perl-Email-Date-Format Y perl-Encode-Detect Y perl-Error Y perl-File-MMagic ****** perl-Geography-Countries ****** perl-HTML-Parser Y perl-HTML-Tabulate ****** perl-HTML-Tagset Y perl-I18N-AcceptLanguage ****** perl-IO-Compress-Base Y perl-IO-Compress-Bzip2 Y perl-IO-Compress-Zlib Y perl-IO-Socket-INET6 Y perl-IO-Socket-SSL Y perl-IO-stringy Y perl-IO-Zlib Y perl-IP-Country ****** perl-LDAP Y perl-libwww-perl Y perl-Locale-gettext ****** perl-Mail-DKIM Y perl-Mail-RFC822-Address ****** perl-Mail-SPF ****** perl-MailTools Y perl-MIME-Lite Y perl-MIME-tools Y perl-Net-DNS Y perl-Net-Ident ****** perl-Net-IP Y perl-Net-IPv4Addr ****** perl-Net-SMTP-SSL Y perl-Net-SSLeay Y perl-NetAddr-IP Y perl-Object-Persistence ****** perl-Package-Constants Y perl-Quota ****** perl-Razor-Agent ****** perl-RPM2 ****** perl-Socket6 Y perl-suidperl Y perl-Test-Inline ****** perl-Text-Iconv Y perl-Text-Template ****** perl-Time-TAI64 ****** perl-TimeDate Y perl-Unix-ConfigFile ****** perl-URI Y perl-version Y perl-WWW-Automate ****** perl-XML-NamespaceSupport Y perl-XML-Parser Y perl-XML-SAX Y
I am now going to try and lob in the existing/missing el5 versions to see what happens. My guess is we will need to rebuild the required modules.
FormMagick
Next will be an attack on FormMagick - there is no package in the default install so need to figure that out. In may indeed be horrible, but we can live with it for now.
Hopefully with perl and FormMagick installed, most of the SME stuff *should* basically install.
