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:
php-cli-5.3.3-46.el6_6.x86_64php-common-5.3.3-46.el6_6.x86_64php-5.3.3-46.el6_6.x86_64
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.rpmwget 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:
[remi]name=Remi's RPM repository for Enterprise Linux 6 - $basearch#baseurl=http://rpms.remirepo.net/enterprise/6/remi/$basearch/mirrorlist=http://rpms.remirepo.net/enterprise/6/remi/mirrorenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
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:
php-common-5.4.45-1.el6.remi.x86_64php-5.4.45-1.el6.remi.x86_64php-cli-5.4.45-1.el6.remi.x86_64
Make sure PHP is working correctly:
php -v
You should see something similar to the following:
PHP 5.4.45 (cli) (built: Sep 2 2015 18:54:00) Copyright (c) 1997-2014 The PHP GroupZend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies
