How To Install Redis in Ubuntu

What is Redis?

Redis is a flexible, open-source, key value data store. Following in the footsteps of other NoSQL databases, such as Cassandra, CouchDB, and MongoDB, Redis allows the user to store vast amounts of data without the limits of a relational database. Additionally, it has also been compared to memcache and can be used, with its basic elements as a cache with persistence.

Set-up Environment For Installation.

Before installing redis, there are a couple of prerequisites that need to be downloaded in-order to proceed with the installation.

1. Update all of the apt-get packages.

 

 

1	sudo apt-get update

 

2. Download a compiler with build essential in-order to install Redis from source.

 

 

1	sudo apt-get install build-essential

 

 3. Download and install tcl8.5

 

 

1	sudo apt-get install tcl8.5

 

 

Install Redis

After all of the prerequisites and dependencies downloaded to the server, you can proceed with the Redis installation from source.

1. Download the Stable Redis release from their website. google code. The latest stable version is 2.8.3

 

1	wget http://download.redis.io/releases/redis-2.8.3.tar.gz

2. Extract the downloaded .tar file, and switch into that directory.

 

1	tar -xvzf redis-2.8.3.tar.gz && cd redis-2.8.3

3. Proceed to with the  make  command.

 

1

make

4. Run the recommended make test .

 

1

make test

5. Do the make install , which installs the program system-wide.

 

1	sudo make install

 

6. Once the program has been installed, Redis comes with a built in script that sets up Redis to run as a background daemon. To access the script move into the utils directory.

 

 

1

cd utils

7. From there, run the Ubuntu/Debian install script.

 

1	sudo ./install_server.sh

 

8. As the script runs, you can choose the default options by pressing enter. Once the script completes, the redis-server will be running in the background. You can start and stop redis with these commands (the number depends on the port you set during the installation. 6379 is the default port setting).

 

 

1 2	sudo service redis_6379 start sudo service redis_6379 stop
