Memcached is a high-performance database system that can help supercharge your application. It's very fast as it does not write to the disk, but instead to system memory.
In this guide, I will explain how to install Memcached on an Ubuntu 14.04 server. This guide covers installing the PHP Memcached plugin too.
Step 1: Verifying prerequisites
There is some required software you need in order to be able to use Memcache:
- MySQL
- PHP
If you do not have these installed yet, install them with apt-get:
apt-get install mysql-server php5-mysql php5
Step 2: Installing Memcache
Once you have MySQL and PHP installed, it's time to install Memcache. You can install Memcached by using apt-get again:
apt-get install memcached
After installing Memcache, you will need to install its PHP extension. This allows for communication between PHP and Memcache:
apt-get install php5-memcached
You may receive the following error:
E: Unable to locate package php5-memcached
If so, update your apt-get repository list:
apt-get update
After that's finished, try again.
Step 3: Editing configuration
The configuration file is located at:
/etc/memcached.conf
Open this file with your favorite text editor should you want to change the port Memcached runs on, the maximum memory, or the number of simultaneous connections.
- -p: port
- -m: memory
- -c: maximum allowed simultaneous connections
Once you have changed these settings, restart the memcached service:
service memcached restart
Congratulations! Memcached is installed on your Ubuntu 14.04 server. You can now configure your applications so that they will use the Memcached database.
