title: Cannot start mongodb back up stop: Unknown instance:
body: <p>So I am trying to restart mongodb 3.2 and enable authorization, so i edit the /etc/mongod.conf file  and added</p>
  
  <pre><code>security:
      authorization:enabled
  </code></pre>
  
  <p>then i saved the file, and typed in </p>
  
  <pre><code>sudo service mongod restart
  </code></pre>
  
  <p>which showed that it restarted correctly, but when I looked at the processes running, mongod is not one of them.
  And now I cant restart it at all.</p>
  
  <p>Also, there was already a database with information in monogodb before i enabled authorization. Im not sure if that is important to know.</p>
  
  <p>I checked out the solutions in here <a href="https://stackoverflow.com/questions/13303685/stop-unknown-instance-mongodb-ubuntu">Stop: Unknown instance mongodb (Ubuntu)</a></p>
  
  <p>but i dont have a " fork = true" statement anywhere in /etc/mongod.conf</p>
