Memcached is a general-purpose distributed in-memory object caching system, which is often used to speed up and optimize back-end dynamic database performance. It does this by temporarily storing data and objects in the servers RAM/memory (like rendering a popular WordPress page on your blog). This reduces the number of direct requests to your databases, saving it time and resources. This also prepares you for any Slashdot effects that could hit your website.
Because systems like Memcached can contribute to denial of service attacks (DoS attack) if not set up correctly, it is essential to secure your Memcached servers. So keep the settings local, or harden your server after setup.
Ubuntu setup
In terminal, over SSH, enter these commands:
apt-get update
apt-get install memcached libmemcached-tools
systemctl start memcached
systemctl enable memcached
apt-get install php-memcached
service apache2 restart
