yum install libevent yum install libmemcached libmemcached-devel
Step 2: Install Memcached Server

(d = daemon, m = memory, u = user, l = IP to listen to, p = port)
Step 4: Check your memcached server is running successfully

Step 9: Restart your apache server
service httpd restart
Step 10: Open your favorite editor to type below code and execute it, it will cache your data into Memcached server and access it back for you
<?php
$memcache = new Memcache;
$memcache->connect('127.0.0.1', 11211) or die ("Could not connect"); //connect to memcached server $mydata = "i want to cache this line"; //your cacheble data $memcache->set('key', $mydata, false, 100); //add it to memcached server $get_result = $memcache->get('key'); //retrieve your data var_dump($get_result); //show it
?>
