CentOS is the best Server distro for the people. Some people, like me, are frustrated at the fact that some software is slow to be updated out of a fresh install: specially PHP.

At the time of this writing, PHP 5.1.x is the version shipped with CentOS 5.4. But my team requires to write application on PHP 5.2.x, so i have to update PHP installation from PHP 5.1.x to PHP 5.2.x by adding additional repository as follows.

Adding Repository

cd /etc/yum.repos.d

Create file centos-test.repo as follows.

 vi /etc/yum.repos.d/centos-test.repo

And add the following Lines in file:

[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

Now use following command to install updtaed version of PHP from test Repository.

yum install php

That’s all
