Step 1. Install SCL repo only by hitting below given command.
yum install centos-release-SCL
Step 2. Install php 5.4 version on system now.
yum install php54
To install specific package, package name should be known. Hence, to get the list of available package list from SCL repo run below given command.
yum list|grep php
Step 3. Activate the PHP 5.4 on system.
NOTE: If you run below given command directly from terminal then on next login you will not find PHP 5.4 path.
source /opt/rh/php54/enable
Basically the above command, make PHP 5.4 executable path and environment available to current login user.
To make PHP 5.4 available to all user , we have to add line source /opt/rh/php54/enable inside file called /etc/profile. Now activate without logout by running command.
source /etc/profile
Or in case, if you only want php 5.4 available to specific user then just only edit .bashrc or .bash_profile file from User’s home directory. And add line source /opt/rh/php54/enable .
Step 4. Now check the php version
php -v
Below given is reference from our system.
[root@localhost ~]# php -v
PHP 5.4.16 (cli) (built: Nov 19 2014 08:05:17)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
[root@localhost ~]#
IMPORTANT NOTE : The PHP 5.4 package actually installed in /opt/rh directory.
ATTENZIONE!!!! Abilitazione x virtualhost
Step n.1: enable the SCL repo and install PHP 5.4
yum install -y centos-release-SCL.x86_64 yum install -y php54.x86_64 php54-php-mysqlnd
Step n.2: create a PHP wrapper script in /var/www/cgi-bin/php54-wrapper
#!/bin/bash source /opt/rh/php54/enable exec php-cgi $1
Then give it the appropriate permissions and restore the selinux context:
restorecon -RF /var/www/cgi-bin/php54-wrapper chown apache:apache /var/www/cgi-bin/php54-wrapper chmod ugo-rwx /var/www/cgi-bin/php54-wrapper chmod ug+rx /var/www/cgi-bin/php54-wrapper
Step n.3: configure the appropiate VirtualHost to use the new PHP version via the CGI interface
AddHandler php-cgi .php Action php-cgi /cgi-bin/php54-wrapper Options +ExecCGI
This configuration instruct Apache to use the new PHP 5.4 version for this and only this Virtualhost, leaving all others configuration intact: other Virtualhosts will continue to use PHP 5.3 version via mod_php.
Nota:
se smette di funzionare occorre rinominare il file
/etc/httpd/conf.d/php54-php.conf
in
/etc/httpd/conf.d/php54-php.conf.vhosts
