Step #1: Install Memcached
As a matter of best practice we’ll update our packages:
apt-get update
Then installing Memcached and related packages is now as simple as running just one command::
apt-get install memcached
Step #2: Configuration of the Memcached Installation
Use the following command to view information on the memcached command:
memcached -h
The default configuration file can be found at:
/etc/memcached.conf
When started, Memcached will start on port 11211 by default per the default configuration file:
# Default connection port is 11211
-p 11211
To change the port, simply change the number in the configuration file.
For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor
EXAMPLE: If I wanted to run Memcached on port 1337, with 4GB of memory, and allow a maximum of 2,000 connections, I would change the config file as follows.
Let’s edit the configuration file:
vim /etc/memcached.conf
To the following:
-p 1337
-m 4096
-c 2000
Exit and save the configuration file, and then restart Memcached
service memcached restart
