title: Mongo authentication issues
body: <p>Hello i have a new AWS server with a Bitnami MEAN stack.</p>
  
  <p>I'm root user on the server, and i started up mongo on the command line.</p>
  
  <p>when i try to do anything (other than "use test" , or "use admin"), such as "show dbs"</p>
  
  <p>I get the following error:</p>
  
  <blockquote>
    <p>show dbs</p>
  </blockquote>
  
  <pre><code> listDatabases failed:{ "ok" : 0, "errmsg" : "unauthorized" } at src/mongo/shell/mongo.js:46
  </code></pre>
  
  <p>I know i'm doing something wrong with regard to permissions, i just dont' know what it is.</p>
  
  <p>when I looked at the mongodb.config, everything looks ok, but i see:</p>
  
  <pre><code>  # Turn on/off security.  Off is currently the default
    #noauth = true
    auth = true
  </code></pre>
  
  <p>Also, possibly relevant, when i try to run  mongod, I get errors about "/data/db" doesn't exist, or if i make the directory, I get "not enough space issues"</p>
  
  <p>thank you for your time.</p>
