Thinking of implementing caching for your php application , you are at a right place. Just in 10 simple (copy and paste) steps you can install and access Memcached Server.
Step1: Install libevent ,libmemcached and libmemcached devel (dependency)
yum install libevent
yum install libmemcached libmemcached-devel
Step 2: Install Memcached Server
Step 3: Start Memcached server
memcached -d -m 512 -l 127.0.0.1 -p 11211 -u nobody
(d = daemon, m = memory, u = user, l = IP to listen to, p = port)
Step 4: Check your memcached server is running successfully
ps -eaf | grep memcached
Step 5: Connect Memcached server via telnet
Step 6: Check current status of Memcached Server on telnet prompt
Step 7: Exit telnet
Step 8: Install PHP client to access Memcached Server
It will make “memcache.so”, you have to just put it on your /etc/php.ini file.
Step 9: Restart your apache server
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
$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
Hurray!! All done!
Enjoy Caching with Memcached.
