How to Install PHP 5.4, 5.5 or 5.6 on CentOS 6 and CentOS 7

Repo Installation

SSH connection to your server and run the following commands 

For CentOS 7 (including EPEL install)

#wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm #wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm #rpm -Uvh remi-release-7*.rpm epel-release-7*.rpm

If you already have EPEL installed:

#wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm #rpm -Uvh remi-release-7*.rpm

For CentOS 6 (including EPEL install)

#wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm #wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm #rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

If you already have EPEL installed:

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

Enabling the Repo

# vi /etc/yum.repos.d/remi.repo.

We need to make sure that the first section [remi] is enabled:

[remi] name=Les RPM de remi pour Enterprise Linux 6 - $basearch #baseurl=http://rpms.famillecollet.com/enterprise/6/remi/$basearch/ mirrorlist=http://rpms.famillecollet.com/enterprise/6/remi/mirror enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

If we want PHP 5.5 or PHP 5.6 we need to do a bit more work, further down in the repo.repo file you will see two additional sections [remi-php55] and [remi-php56], decide which PHP version you want to install and then enable the correct. So for PHP 5.6 we would change to:

[remi-php56] name=Les RPM de remi de PHP 5.6 pour Enterprise Linux 6 - $basearch #baseurl=http://rpms.famillecollet.com/enterprise/6/php56/$basearch/ mirrorlist=http://rpms.famillecollet.com/enterprise/6/php56/mirror # WARNING: If you enable this repository, you must also enable "remi" enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Once you made your changes save your modified file and quit your editor.

Installing PHP

#sudo yum -y install httpd mysql mysql-server mysql-devel php php-mysql php-fpm #service httpd restart #php-v Enjoyed!
