Recently one of my clients requested that he needs php5 on one of his production servers. The server runs CentOS 4.7 x86_64. I had recently migrated this server from RHEL 4.7 (see Migrating RHEL 4.6 to CentOS 4.6).
PHP5 is present in the CentOSPlus repository. Since I had yum-priorities plugin installed and specified the priority of 2 for the CentOSPlus repository, the package just can not be installed like that. At this moment I took the opportunity of installing the entire webstack from the CentOSPlus repository.
Following is my repository configuration specified in /etc/yum.repos.d/CentOS-Base.repo. The exclude line in the base and update repositories exclude the web stack packages from these repositories as we will be taking them from the CentOSPlus repository.

After this, when I did tried to upgrade php to php5 as:
# yum --enablerepo=centosplus update php
I received some transaction check errors as shown below:

So I decided to update the mysql also. and the following worked:
# yum --enablerepo=centosplus update php mysql
Later on I upgraded the other critical component httpd also as follows:
# yum --enablerepo=centosplus update httpd
