Here we will install a single Redis instance running on one server. To get Redis, we will perform the following steps:

1. First navigate your way out to the Redis IO download page: https://redis.io/download. Unless you are an advanced user of Redis, you will want the stable release (Redis 4.0.8 as of the time of writing).
2. Download Redis, create a local directory, and move it there:

sudo mkdir /local
sudo chown $USER:$USER /local
cd /local
mv ~/Downloads/redis-4.0.8.tar.gz . 

3. Now we can untar it, and it should create a directory and expand the files into it:

tar -zxvf redis-4.0.8.tar.gz

4. Many people find it more convenient to rename this directory:

mv redis-4.0.8/ redis

5. The browser interaction can be skipped entirely, by hitting redis.io download site for the latest, stable release with either wget or curl from the command line:

curl -O http://download.redis.io/redis-stable.tar.gz  

6. And for the purposes of this example, it will also be untarred and renamed to redis:

tar -zxvf redis-stable.tar.gz
mv redis-stable/ redis  

7. At this point, all that has been downloaded is the source code:

sudo apt-get update
sudo apt-get install gcc make tcl build-essential

8. Next, cd into the Redis directory, and build it:

cd redis
make 

If all of the tests passed, you should see a message similar to the following:

\o/ All tests passed without errors!
