What is Memcached?
Memcached is a very powerful memory object caching system. It is used to speed up dynamic web applications by alleviating database load.
Installation of memcached on Ubuntu 12.04 is very simple. On the terminal, let's typing following command:
sudo apt-get install memcached
sudo apt-get install php5-memcache
sudo /etc/init.d/apache2 restart
To test it by entering:
telent localhost 11211
if memcached is installed successful, the above command will return:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
The official site of Memcached is here.
