title: redis refuses to start
body: <p>I've installed redis according to <a href="https://www.digitalocean.com/community/tutorials/how-to-install-and-use-redis" rel="nofollow">this tutorial</a>. Everything works fine until I run <code>sudo service redis_6379 start</code> at which point I get the error
  <code>Failed to start redis_6379.service: Unit redis_6379.service failed to load: No such file or directory.
  </code>
  When I check I see that redis is not running:</p>
  
  <pre><code>&gt; sudo service redis_6379 status
  ● redis_6379.service
  Loaded: not-found (Reason: No such file or directory)
  Active: inactive (dead)
  </code></pre>
  
  <p>I'm not sure what this <code>redis_6379.service</code> file is, or how I can create it? any help?</p>
  
  <p>EDIT: tried installing using <code>sudo apt-get install redis-server</code> and got the following errors:</p>
  
  <pre><code>adduser: Warning: The home directory `/var/lib/redis' does not belong to the user that you are currently creating.

  <p>I created recall creating the scripts <code>shlonsky</code> and <code>unicorn_my_app</code> to start nginx and unicorn, but I didn't think they would affect further .service instillation. any idea what I need to do to allow .service files to install?</p>
