Memcache is a free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
Installation from Linux Packages
Ubuntu & Debian
apt-get install memcached libmemcached php5-memcached
yum install memcached
Installation from EasyApache (WHM/cPanel)
EasyApache MemCache is the Apache module rather than the PHP module as we do not list or provide the PHP module there. When you compile EasyApache with the MemCache Apache module, you end up with it available via Apache only not via PHP.
