If you try to install memcached with Linux server then use following commands
# yum install libevent
# yum install libmemcached libmemcached-devel
# yum install memcached
For Starting the memcached server
# memcached -d -m 512 -l 127.0.0.1 -p 11211 -u nobody
11211 port is default port for memcached server.
For using the memecached with php client you need to install following package
# pecl install memcache
After installing all packages restart the apache server.
# /etc/sbin/service httpd restart
<?php
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$memcache_obj->set('any_key', 'some value', MEMCACHE_COMPRESSED, 50);
echo $memcache_obj->get('any_key');
?>
