For those of you who didn’t know, Redis is an open-source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, and sorted sets. Redis also supports datatypes such as Transitions, Publish, and Subscribe. ‘Redis ’ is considered more powerful than ‘Memcache’. It would be smart to bring ‘Redis’ into practice and put ‘Memcache’ down for a while.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation Redis on Ubuntu 14.04.
Install Redis on Ubuntu 14.04
Step 1. First, add the Dotdeb repositories to your APT sources.
Create a new list file in /etc/apt/sources.list.d/ and fill it with the following content:
# /etc/apt/sources.list.d/dotdeb.org.list deb http://packages.dotdeb.org squeeze all deb-src http://packages.dotdeb.org squeeze all
Then you need to authenticate these repositories using their public key:
wget -q -O - http://www.dotdeb.org/dotdeb.gpg | sudo apt-key add -
Step 2. Install Redis using apt-get.
sudo apt-get update sudo apt-get install redis-server
Enable Redis service to start on boot:
sudo service redis_6379 start sudo service redis_6379 stop
Check if Redis is working.
The first thing to do in order to check if Redis is working properly is sending a PING command using redis-cli:
$ redis-cli ping PONG ### If you get PONG in return that means redis server is working fine on server ###
Step 3. Install Redis PHP extension.
Redis provides a PHP extension to work with PHP. Here we will cover the installation of Redis Extension of PHP from source compilation and using
apt the repository. The following command will install and set up Redis extension with PHP:
sudo apt-get -y install php5-redis
Congratulations! You have successfully installed Redis. Thanks for using this tutorial for installing the Redis server on Ubuntu 14.04 system.
