Install PHP 5.2.6 on CentOs 5.x

Oddly enough, PHP 5.2.6 is still not available on default CentOS repositories ([base], [updates], [addons], and [extras]), latest PHP available in those repos is PHP 5.1.6!

In order to install PHP 5.2.6 you can add the CentOS testing repository and enable it then install or update PHP.

To add the CentOS testing directory, create a file /etc/yum.repos.d/centos-test.repo and add this line:

[c5-testing]
name=CentOS-5 Testing
baseurl=http://dev.centos.org/centos/5/testing/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing


Then install or update PHP:

[root@server ~]# yum install php

or

[root@server ~]# yum update php

Then you can disable the testing repo by editing the file and setting the option “enabled” to “0″

[c5-testing]
name=CentOS-5 Testing
baseurl=http://dev.centos.org/centos/5/testing/$basearch/
enabled=0
gpgcheck=1
gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing
