Centos is a great Distro for hosting. Its tried and tested, as oppossed to Fedora and Ubuntu, which, while on the cutting edge, can still have a few quirks. My biggest problem with Centos is that lack for cutting edge, like the default PHP that installs with Centos, 5.1. It can be a pain to find 3rd party repos.
Well hopefully thats where you are. Looking for 5.3 on Centos. One of the most solid repos out there is . I’ll run through how to get that version of php you want on your server.
This assumes you have no php installed at this point. If you do, back up and remove it. Once you are ready:
Have to add the Epel repo first, so run these two commands as root
wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm
Now lets add the IUS Community Repo
wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1.0-6.ius.el5.noarch.rpm rpm -Uvh ius-release-1.0-6.ius.el5.noarch.rpm
This will add the repos to your /etc/yum.repos.d/ directory. Now to go into the .repo file and make a few changes.
The repo configuration file by default is configured to hit the mirrorlist. Lets set the base url and make sure the repo is enabled.
First comment out the “mirrorlist=http” line in the main ius repo, and then make sure “enable=1″. The first section of your ius.repo should look like this:
[ius] name=IUS Community Packages for Enterprise Linux 5 - $basearch baseurl=http://dl.iuscommunity.org/pub/ius/stable/Redhat/5.5/$basearch #mirrorlist=http://dmirr.iuscommunity.org/mirrorlist?repo=ius-el5&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/IUS-COMMUNITY-GPG-KEY
Awesome. Now the was IUS does things, is they name php based on version, so php 5.3 is php53u and if you wanted 5.2 it would just be php52. An easy way to check, would be do a yum list:
yum list php53u
Or to see all php53u packages:
yum list php53u*
Now just yum install the packages you need and you’ll be running on a fresh version of php 5.3.
