Update PHP to 5.5 on CentOS 6.4
Today I had to update a server running CentOS 6.4 to have PHP 5.5. This is actually easier than you may think.
Firstly I did a
yum update this updated the server to version 6.5 and on to PHP. First PHP 5.5 is not in the main repositories so we need to enable the remi repo and while we are at it the epel repo.
So make sure you have wget
sudo yum install wget
Then download the epel and remi repos:
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
Now enable the remi repo (I like to use nano, which nicer I think than vi):
sudo nano /etc/yum.repos.d/remi.repo
Now change enabled to 1 on the
[remi] and on the
[remi-php55]. so those sections should look like:
[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 [remi-php55] name=Les RPM de remi de PHP 5.5 pour Enterprise Linux 6 - $basearch #baseurl=http://rpms.famillecollet.com/enterprise/6/php55/$basearch/ mirrorlist=http://rpms.famillecollet.com/enterprise/6/php55/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
To update your PHP to 5.5 you only have to do:
sudo yum update sudo service httpd restart
And that's it you have php 5.5 to check:
[[email protected] ~]# php -v PHP 5.5.11 (cli) (built: Apr 3 2014 07:55:14) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies
Now PHP 5.5 has and OPcache build in to so to take advanage of that we do:
sudo yum install php-opcache sudo service httpd restart
Now your PHP has built in cache support which will make your scripts faster.
