Installing PHP extension Memcached on RHEL6

I couldn't find the memcached extension for PHP in the base installation of Red Hat Enterprise Linux 6, so here are instructions for installing memcached on RHEL6:

This assumes your Red Hat Enterprise Linux 6 server has its license working:

shell#  rhn_register --nox

First install the EPEL repository for RHEL6 (all one line):

shell#  yum install http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm

Install PHP into your Red Hat EL6:

shell#  yum install php

Visit the Red Hat website and get the php-devel packages and these various libmemcached files:

• php-devel (both i686 and x86_64)
• libmemcached (both i686 and x86_64)
• libmemcached-devel (both i686 and x86_64)

Download each of the above files and install them:

shell#  yum install ./*.rpm

Then install the PHP packages that we need:

shell#  yum install php-pecl-memcached php-pear

Restart your httpd (Apache2) service:

shell#  service httpd restart

You can check this in a web browser by creating a file info.php containing the following code, and browsing to that to see what PHP extensions and the like are running:

<?php
 phpinfo();
?>

It should look like this (and much more) when you visit that info.php page:
