Version
Description
The purpose of the contribs is to install PHP54, PHP55, PHP56, PHP70, PHP71 alongside the default php version installed with SME9 without having to remove or change the default php installation. We use the rpms from the remi-safe repository which are in fact the same as those on the official official web site, but have the advantage of providing more choices.
All PHP rpms are installed in /opt , this prevents any interference or conflict with the default install of PHP.
Requirements
Installation
Base installation
Simple repo installation
These repos can now be easily added using a rpm
yum --enablerepo=smeaddons install smeserver-extrarepositories-epel, smeserver-extrarepositories-remi-safe
Manual repo installation
Remember to first configure the required remi-safe repository,
issue the following command on the SME Server shell:
/sbin/e-smith/db yum_repositories set remi-safe repository \ Name 'Remi - safe' \ BaseURL 'http://rpms.famillecollet.com/enterprise/$releasever/safe/$basearch/' \ EnableGroups no \ GPGCheck yes \ GPGKey http://rpms.famillecollet.com/RPM-GPG-KEY-remi \ Visible yes \ status enabled
In the future you may also need epel repository, although currently it is not required
yum install smeserver-extrarepositories-epel -y
then you need to issue this command before installing:
signal-event yum-modify
the minimal installation can simply be done doing :
yum install smeserver-php-scl --enablerepo=smecontribs
If you do not want to restart your server
signal-event php-update; config set UnsavedChanges no
or
signal-event post-upgrade; signal-event reboot
Go to the php-scl panel on Server Manager and activate the version of php you desire for each Ibay, or if you need for the whole server.
if you need additional php packages consider advanced install
Advanced installation
To install additional php rpm, as an example you might need the following components of php : php56-php-pecl-rar php56-php-libvirt php56-php-magickwand
yum install smeserver-php-scl php56-php-pecl-rar php56-php-libvirt php56-php-magickwand --enablerepo=smecontribs,epel
If you need additional PHP modules (e.g. for Nextcloud, Redis) you need to include the required PHP Redis modules (php71-php-pecl-redis php70-php-pecl-redis):
yum --enablerepo=remi,epel install php71-php-pecl-redis php70-php-pecl-redis
If you do not want to restart your server
signal-event php-update; config set UnsavedChanges no
or
signal-event post-upgrade; signal-event reboot
Go to the php-scl panel on Server Manager and activate the version of php you desire for each Ibay, or if you need for the whole server.
Limitation
If you use scl_php56/scl_php54/scl_php55 for the whole server, You can add also specific values (MemoryLimit,UpMaxFileSize,PostMaxSize,MaxExecTime,AllowUrlfOpen) per Ibay (either by db command or by the contrib smeserver-webhosting) because apache is the handler of php.
If you use scl_php71,scl_php70,scl_php56,scl_php55,scl_php54 per ibay, then you use php with a cgi application and you cannot add specific setting to apache with php_admin_flag or php_admin_value. Then if you want to add a specific setting like in Usage you must use it for the whole php applications by the command you can find in Usage
It is the limitation of php-scl
In short
- PHP SCL for the whole server -> all settings can be set per Ibay normally with db or with smeserver-webhosting (these settings will overwritten those set in Usage)
- PHP SCL per Ibay -> all settings must be set in each php{54,55,56} properties like in Usage. Of course all php applications (whatever the Ibay) will share the same settings.
Usage
When you want to change the version of php, you can use the panel (Php-Scl versions), either for changing the php version for an Ibay or for the whole server.
However if you want to change settings of a specific php version you have to use the command line, first see the new db entries.
After each modification don't forget to launch the event 'signal-event php-update'
[root@sme9b3dev64 ~]# config show php54 php54=configuration AllowUrlFopen=Off #(On/Off) MaxExecutionTime=30 MaxFileUpload=20 MaxInputTime=60 MemoryLimit=128M PhpModule=disabled #(enabled/disabled) PostMaxSize=20M UploadMaxFilesize=10M
[root@sme9b3dev64 ~]# config show php55 php55=configuration AllowUrlFopen=Off #(On/Off) MaxExecutionTime=30 MaxFileUpload=20 MaxInputTime=60 MemoryLimit=128M PhpModule=disabled #(enabled/disabled) PostMaxSize=20M UploadMaxFilesize=10M
[root@sme9b3dev64 ~]# config show php56 php56=configuration AllowUrlFopen=Off #(On/Off) MaxExecutionTime=30 MaxFileUpload=20 MaxInputTime=60 MemoryLimit=128M PhpModule=disabled #(enabled/disabled) PostMaxSize=20M UploadMaxFilesize=10M
[root@sme9b3dev64 ~]# config show php70 php70=configuration AllowUrlFopen=Off #(On/Off) MaxExecutionTime=30 MaxFileUpload=20 MaxInputTime=60 MemoryLimit=128M PhpModule=disabled #(enabled/disabled) PostMaxSize=20M UploadMaxFilesize=10M
[root@sme9b3dev64 ~]# config show php71 php71=configuration AllowUrlFopen=Off #(On/Off) MaxExecutionTime=30 MaxFileUpload=20 MaxInputTime=60 MemoryLimit=128M PhpModule=disabled #(enabled/disabled) PostMaxSize=20M UploadMaxFilesize=10M
in fact you can choose manually (think about you have a panel for that) which version you want to use in the phpmod of apache (only one version can be used), for example
config setprop php56 PhpModule enabled signal-event php-update
Since just one version can be used with php-mod, the lower version is used....all disabled and it is the php default version which is used
Run a command with a specific software environment
You can run a command from the shell with a specific env with:
scl enable php55 'php -v'
(useful for example if you need to run a cron job with an alternative PHP version)
Find other RPMS
If you want to see available rpm
yum list available php5\* --disablerepo=* --enablerepo=remi-safe
For example if you want to install the php rpm for pgsql
yum install php54-php-pgsql php55-php-pgsql php56-php-pgsql php70-php-pgsql php71-php-pgsql --enablerepo=remi-safe
Update
base install
- If you enabled smecontribs repo there will be nothing to do, all updates will propagated on their own with usual updates as remi-safe is enabled.
- If smecontribs is not enabled, you will need to issuethe following:
yum update smeserver-php-scl php54* php55* php56* php70* php71* --enablerepo=smecontribs
Advanced install
The repo remi-safe is enabled by default as it has no conflicts with base installation. Please do not enable epel repo by default, as you might break you system or at least the update process.
regularly you should check for updates and apply them by doing so:
yum update smeserver-php-scl php54* php55* php56* php70* php71* --enablerepo=smecontribs,remi-safe,epel
Uninstall
yum remove smeserver-php-scl
Custom Templates
If you need to modify the php.ini you can add a custom template.
Make a new directory here and add you template fragment:
/etc/e-smith/templates-custom/opt/remi/php{$ver}/root/etc/php.iniDebug
Setup
This demonstrates how to get xdebug going for a given version - in this case PHP 5.6
yum --enablerepo=remi-safe install php56-php-pecl-xdebug
For OpenBaseDir errors add the pear path:
db accounts setprop myibay PHPBaseDir /home/e-smith/files/ibays/myibay/html/:/usr/share/pear/:/usr/share/pear-addons/:/tmp/:/opt/remi/php56/root/usr/share/pear/
signal-event php-update;signal-event ibay-modify
Enable
To enable the debugger:
Now edit the following file according to your needs:
/etc/e-smith/templates/opt/remi/php56/root/etc/php.ini
Standard direct connection
[Debugger] debugger.host = localhost debugger.port = 7869 debugger.enabled = False
zend_extension = "/usr/lib64/php/modules/xdebug.so" zend_debugger.allow_hosts = 192.168.10.0/24 zend_debugger.expose_remotely = always zend_debugger.httpd_uid = 102 zend_debugger.httpd_uid = -1
signal-event php-update
You should be able to connect with your debugger pointed to the correct port and IP address of the server, and using a URL like this:
https://test.myserver.com/TestFile.php?XDEBUG_SESSION_START
Using pydbg proxy
[Debugger] xdebug.remote_enable = true xdebug.remote_host = 127.0.0.1 xdebug.remote_port = 9000 xdebug.remote_handler = dbgp xdebug.remote_log = /var/log/xdebug.log xdebug.remote_mode = req xdebug.idekey = users
signal-event php-update
Then run the debug proxy with something like this
python /root/dbgp/bin/pydbgpproxy -d 127.0.0.1:9000 -i 192.168.10.1:9001 -l DEBUG
You should be able to connect with your debugger pointed to the correct port 9001 and IP address of your server, and using a URL like this:
https://test.myserver.com/TestFile.php?XDEBUG_SESSION_START=users
Cannot access Webmail or Server Manager
If you find that you can not access Webmail or server manager then you can disable PHP SCL as follows:
Global
config setprop php{$ver} PhpModule disabled|enabled
signal-event php-update
eg
config setprop php71 PhPModule disabled signal-event php-update
You should now be able to access Webmail
As a side note this is how to do it per ibay For an individual ibay
db {ibayname} setprop php{$ver} PhpVersion disabled|enabled
signal-event php-update
