CageFS and PHP Selector (Installation) in CloudLinux

CageFS and PHP Selector are two major components of Cloud Linux.

The installation of PHP Selector

PHP Selector is a CloudLinux component that sits on top of CageFS. It allows each user to select PHP version & module based on their needs. PHP Selector requires account to have CageFS enabled to work.

1) The installation of PHP Selector presumes that you already have CageFS & LVE Manager installed.

2) Installation of different versions of PHP & modules:

$ yum groupinstall alt-php

3) Update CageFS & LVE Manager with support for PHP Alternatives

$ yum update cagefs lvemanager

inside CageFS

-l | –list            : List available alternatives for item specified

-L | –list-extensions : List available extensions for a user

-e | –enable          : Enable an extension for a user

-i | –interpreter     : Specify an interpreter for an extension (e.g. php)

========================

The installation of CageFS Selector

CageFS is a virtualized file system and a set of tools to contain each user in its own ‘cage’. Each customer will have its own fully functional CageFS, with all the system files, tools, etc…

To install CageFS:

$ yum install cagefs
$ /usr/sbin/cagefsctl –init

That last command will create skeleton directory that might be around 7GB in
size.

If your /usr/share not have enough disk space, then follow the steps below to place cagefs skeleton in different location.

$ mkdir /home/cagefs-skeleton

$ ln -s /home/cagefs-skeleton /usr/share/cagefs-skeleton

CageFS will automatically detect and configure all necessary files for:

•       cPanel
•       Plesk
•       DirectAdmin
•       ISPmanager
•       Interworx
•       MySQL
•       PostgreSQL
•       LiteSpeed
