In this post we will install php 5.4 on CentOS 6 with yum command . In available default repo of CentOS, we will get the php 5.3 version. Some PHP developers uses the PHP 5.4 version for application, hence we need PHP 5.4 to be installed on CentOS 6.x .
It is known that in CentOS 6 series versions, we can not get the PHP 5.4 version from default yum repo .
To install php 5.4 on CentOS 6.x, we will use the SCL repo. In terms of SoftwareCollections.org (SCL), “Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages.”
Lets start the installation of PHP 5.4 .
Step 1. Install SCL repo only by hitting below given command.
yum install centos-release-SCL
Step 2. Install php 5.4 version on system now.
yum install php54
To install specific package, package name should be known. Hence, to get the list of available package list from SCL repo run below given command.
yum list|grep php
Step 3. Activate the PHP 5.4 on system.
NOTE: If you run below given command directly from terminal then on next login you will not find PHP 5.4 path.
Basically the above command, make PHP 5.4 executable path and environment available to current login user.
To make PHP 5.4 available to all user , we have to add line
source /opt/rh/php54/enable inside file called
/etc/profile. Now activate without logout by running command.
Or in case, if you only want php 5.4 available to specific user then just only edit .bashrc or .bash_profile file from User’s home directory. And add line
source /opt/rh/php54/enable .
Step 4. Now check the php version
Below given is reference from our system.
