Centos how to upgrade from PHP 5.2 to 5.3 without downtime

This may sound silly but there will be conflicts/issues with the default Centos repository so you have to use a third party like remi (I prefer not to do this but it's the only option unless you migrate your sites/data to another server or can stand some downtime-not an option IMHO on a production server).

You may need to upgrade to PHP 5.3 to run Joomla or many other reasons.

Your host needs to use PHP 5.2.4 or higher to run this version of Joomla!

 You could try using --skip-broken to work around the problem

The program package-cleanup is found in the yum-utils package.

As you can see it's not possible to upgrade to 5.3 because it conflicts with the default 5.2 install, there's no common-sense way to upgrade it without fully removing the existing PHP.

So we have to enable remi, a third party repo that will make this work


wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
rpm -ivh remi-release-5.rpm


yum --enablerepo=remi update php php-*

 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

We run into an issue with php-readline and php-syck and have to remove them to make remi happy.


yum remove php-readline php-syck

Run the install again and it will work.

You may get some weird messages from PHP/MySQL but everything seems to work.

I really do not like this method because it even updates MySQLD in the process for some reason.  Beware that when doing this the newer 5.0 version of MySQL will not let you login with a 16-character+ username this means sites/databases won't work unless you create a user with less characters (this is a weird feature of the new version and is ridiculous in my opinion).  I thought I'd mention it because I spent a lot of time troubleshooting why some databases no longer connected.
