+=========================================
+Installing PHP 5.4 on RHEL 6 and CentOS 6
+=========================================
+
+Red Hat Enterprise Linux and CentOS 6 still ship with PHP 5.3. ownCloud 
+requires PHP 5.4 or better. There are several third-party repositories that 
+supply PHP 5.4, but you must use the Software Collections (SCL) repository to 
+be in compliance with your RHEL support contract, and not any other third-party 
+repository.
+
+RHEL 6
+------
+
+Follow these steps to install PHP 5.4 from SCL. First you must use 
+your Subscription Manager to enable SCL::
+
+ subscription-manager repos --enable rhel-server-rhscl-6-eus-rpms
+ 
+Then install PHP 5.4 and these modules::
+
+ yum install php54 php54-php php54-php-gd php54-php-mbstring
+
+You must also install the updated database module for your database. This 
+example installs the new PHP 5.4 module for MySQL/MariaDB:: 
+ 
+ yum install php54-php-mysqlnd
+ 
+Activate the new PHP version permanently::
+ 
+ source /opt/rh/php54/enable
+ 
+Disable loading the old PHP 5.3 Apache module:: 
+
+ mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf/old
+ 
+You should now have a /etc/httpd/conf.d/php54-php.conf file, which loads the 
+correct PHP 5.4 module for Apache.
+
+Then restart Apache::
+ 
+ service httpd restart
+
+Verify with ``phpinfo`` that your Apache server is using PHP 5.4 and loading 
+the correct modules; see   
+https://doc.owncloud.org/server/8.1/admin_manual/configuration_server/performance_tuning.html#php-version-and-information to learn how to use ``phpinfo``.
+
+CentOS 6
+--------
+
+First install the SCL repo::
+
+ yum install centos-release-SCL
+ 
+Then install PHP 5.4 and these modules:: 
+
+ yum install php54 php54-php php54-php-gd php54-php-mbstring
+ 
+You must also install the updated database module. This installs the new PHP 5.4 
+module for MySQL/MariaDB:: 
+ 
+ yum install php54-php-mysqlnd
+ 
+Activate the new PHP version permanently::
+ 
+ source /opt/rh/php54/enable
+ 
+Disable loading the old PHP 5.3 Apache module:: 
+
+ mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf/old
+ 
+You should now have a /etc/httpd/conf.d/php54-php.conf file, which loads the 
+correct PHP 5.4 module for Apache.
+
+Finally, restart Apache::
+ 
+ service httpd restart
+
+Verify with ``phpinfo`` that your Apache server is using PHP 5.4 and loading 
+the correct modules; see   
+https://doc.owncloud.com/server/8.1/admin_manual/configuration_server/
+performance_tuning.html#php-version-and-information to learn how to use 
+``phpinfo``.
