Check this out : https://www.mojowill.com/geek/howto-install-php-5-4-5-5-or-5-6-on-centos-6-and-centos-7/
I still use CentOS as my distro of choice on any new server and whilst things are getting better CentOS and RHEL still don’t have up to date versions of PHP available inside the default yum repos. A couple of years ago I posted about Howto install PHP Mcrypt on CentOS using EPEL which is one of my sites most popular posts!
So CentOS and PHP, as you can see below (taken from DistroWatch) CentOS is a bit outdated with it’s PHP versions which as a PHP developer can be a pain in the ass!
| PHP Current Version | CentOS 7.0-1406 | CentOS 6.6 |
|---|---|---|
| 5.6.4 | 5.4.16 | 5.3.3 |
However there is yet again hope! This time we need 2 additional repos. First up we need EPEL and secondly we need Remia French guy who is king of PHP repos!
Repo Installation
Open up a SSH connection to your server and run the following commands (make sure you run as sudo if you need to):
For CentOS 7 (including EPEL install)
1
2
3
| wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpmwget http://rpms.famillecollet.com/enterprise/remi-release-7.rpmrpm -Uvh remi-release-7*.rpm epel-release-7*.rpm |
If you already have EPEL installed:
1
2
| rpm -Uvh remi-release-7*.rpm |
For CentOS 6 (including EPEL install)
1
2
3
| rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm |
If you already have EPEL installed:
1
2
| rpm -Uvh remi-release-6*.rpm |
Enabling the Repo
Now we need to make sure the repo is enabled and select which version you want to install. We need to head over to
/etc/yum.repos.d you should inside see a file called remi.repo.
Open the file in your favourite editor (Nano, Pico, Vi etc), you’ll see a number of sections. We need to make sure that the first section
[remi] is enabled:
1
2
3
4
5
6
7
| [remi]name=Les RPM de remi pour Enterprise Linux 6 - $basearch#baseurl=http://rpms.famillecollet.com/enterprise/6/remi/$basearch/enabled=1gpgcheck=1 |
Note the line
enabled=1 make sure this is set! Now technically you can actually go ahead and install PHP, but you will only get PHP 5.4.*. Which might be want to you want is so skip ahead to the next section!
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:
1
2
3
4
5
6
7
8
| [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/# WARNING: If you enable this repository, you must also enable "remi"enabled=1gpgcheck=1 |
Once you made your changes save your modified file and quit your editor.
Installing PHP
Now I’m assuming you don’t already have PHP installed, this bit is super simple.
1
| sudo yum install php php-gd php-mysql php-mcrypt |
So the above assumes you want MySQL, GD and Mcrypt support in your PHP, but you should see something like the below depending on which version of PHP you are trying to install:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

As you can see PHP is installing version 5.5.20-2.el6.remi from the remi-php55 repo! Once you have hit Y to confirm the install restart apache and magical unicorns you have a better version of PHP!
You can also change your mind in the future by going back into the
remi.repo file and enable a different PHP version and then run yum update and if you have moved from 5.5 to 5.6 it will upgrade PHP for you. If you want to downgrade for any reason you will need to remove PHP (sudo yum remove php*) and then reinstall the PHP modules you want.
Hope this helps!
