I’m going to show you how to upgrade PHP 5.3 to PHP 5.4 on CentOS 6.7. This article is assuming that you are running the CentOS 6.7 default version of PHP 5.3.


1. Confirm your version of PHP is the CentOS 6.7 default


Type in the following:


rpm -qa | grep php


Should output similar to the following:




Great, let’s move on.


2. Install and activate the REMI and EPEL RPM Repositories


Type in the following to download and install the required files:


wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm && rpm -Uvh epel-release-latest-6.noarch.rpm

wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm && rpm -Uvh remi-release-6*.rpm


Now to enable the REMI repository globally:


nano /etc/yum.repos.d/remi.repo


Under the section that looks like [remi] make the following changes:


name=Remi's RPM repository for Enterprise Linux 6 - $basearch


Press CTRL-O to save, and CTRL-X to exit, and we can continue.


3. Update PHP from 5.3 to 5.4


Easy as pie, simply type in the following:


yum -y update php*


Once that’s done, we can verify:


rpm -qa | grep php


And we should see something similar to the below:




Make sure PHP is working correctly:


php -v


You should see something similar to the following:
