Install Memcached on Ubuntu 14.04

• First, update and upgrade your server

  apt-get update && apt-get upgrade -y

• Then, install memcached service

  apt-get install memcached -y

• Now, you have to modify a couple of parameters. Feel free to set this up as you wish.

    # Amount of memory that memcached daemon will use
    -m 700
  
    # Set ip address
    -l X.X.X.X
  
    # Port to listen
    -p 11211
  

• Finally, restart the service

  service memcached restart

• To check if memcached is up and running

  echo stats | nc 127.0.0.1 11211

  you should see and output like this
