This tutorial will show you how to upgrade PHP 5.4 to PHP 5.6 on CentOS 7.5.
The assumption is that you are running a stock installation of CentOS, and already have PHP 5.4 installed.
1. Verify current version of PHP
Type in the following to see the current PHP version:
The output should match this:
PHP 5.4.16 (cli) (built: Apr 12 2018 19:02:01) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
Perfect, let’s continue!
2. Install the REMI and EPEL repositories
If you don’t already have them, install the Remi and EPEL repositories:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://rpms.remirepo.net/enterprise/remi-release-7.rpm
Enable the Remi repository globally:
Under the section that looks like [remi] make the following changes:
[remi] name=Remi's RPM repository for Enterprise Linux 7 - $basearch #baseurl=http://rpms.remirepo.net/enterprise/7/remi/$basearch/ #mirrorlist=https://rpms.remirepo.net/enterprise/7/remi/httpsmirror mirrorlist=http://cdn.remirepo.net/enterprise/7/remi/mirror enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
Also, under the section that looks like [remi-php55] make the following changes:
[remi-php56] name=Remi's PHP 5.6 RPM repository for Enterprise Linux 7 - $basearch #baseurl=http://rpms.remirepo.net/enterprise/7/php56/$basearch/ #mirrorlist=https://rpms.remirepo.net/enterprise/7/php56/httpsmirror mirrorlist=http://cdn.remirepo.net/enterprise/7/php56/mirror # NOTICE: common dependencies are in "remi-safe" enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
Type CTRL-O to save and CTRL-X to close the editor
3. Upgrade PHP 5.4 to PHP 5.6
Now we can upgrade PHP. Just type in the following command:
yum -y upgrade php*
Once the upgrade has completed, verify that you have PHP 5.6 installed:
Output should look like:
PHP 5.6.38 (cli) (built: Oct 24 2018 12:50:38) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
Sweet deal, upgrade is done!!
