How to install Memcached on a CentOS

Posted on

Memcached is an in-memory key-value store for small chunks of arbitrary data (strings or objects) from results of database calls, API calls, or page rendering.  Memcached will store sessions in memory instead of files. Because memory is way faster than reading a file your website will perform better and reduce load time.

Update the repositories

yum update -y

Start the installation

yum install memcached

Configure Memcached

vi /etc/sysconfig/memcached

Start Memcached
chkconfig --levels 235 memcached on
/etc/init.d/memcached start
