title: Failed to unlink socket file /tmp/mongodb-27017.sock errno:13 Permission denied
body: <p>When I try to start mongo db I get the following error:</p>
  
  <pre><code>Trying to run the command : ./mongod --dbpath=../data
  Failed to unlink socket file /tmp/mongodb-27017.sock errno:13 Permission denied
  Fatal Assertion 28578
  </code></pre>
  
  <p>As per the suggestions from other posts, have tried to locate the file <code>/tmp/mongodb-27017.sock</code>, to delete. But the file itself is not available.</p>
  
  <p>But when I tried to do it using root, I am able to start the mongo DB. For normal users it fails.</p>
