Update PHP and MySQL on CentOS 5.3

I have a VPS server. The OS is CentOS 5.3 (final)
It is running very well. Because I like to keep software updated. So I use yum command to update it.

It told me nothing to update. OK.

PHP 5.2.6 and MySQL 5.0.77 installed on CentOS 5.3

To keep it update, I have to add repository.

Let me describe the steps.

1) SSH to the server

2) Run following command

#rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
#vi /etc/yum.repos.d/utterramblings.repo

3) Add following content into the utterramblings.repo

[utterramblings]
name=Jason's Utter Ramblings Repo
baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
