- These instructions are intended specifically for installing Memcached on a single Ubuntu 12.04 LTS node.
- I’ll be working from a Liquid Web Core Managed Ubuntu 12.04 LTS server, and I’ll be logged in as root.
Step #1 Install MemcachedAs a matter of best practice we’ll update our packages:
apt-get updateThen installing Memcached and related packages is now as simple as running just one command::
apt-get install memcached
Step #2: Configuration of the Memcached InstallationUse the following command to view information on the memcached command:
memcached -hThe 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.confTo the following: -p 1337 -m 4096 -c 2000 Exit and save the configuration file, and then restart Memcached
service memcached restart
