title: how do I edit the Mondodb.conf file
body: <p>How do I edit the mongodb.conf file? </p>
  
  <p>I want to change the bind_ip from <code>127.0.0.1</code> to <code>0.0.0.0</code>. </p>
  
  <p>I have tried <code>sudo mongod --bind_ip 0.0.0.0</code>
  I have tried manually editing the file (in a text editor), but it won't let me save.
  I have tried changing the permissions of the file, yet I still can not save. </p>
  
  <p>I didn't create a mongodb.conf file either, so I'm not sure why it was automatically set up as 127.0.0.1</p>
  
  <p>I'm using Ubuntu.</p>
  
  <p>I've tried searching around but I haven't had any luck. </p>
  
  <p>All suggestions will be much appreciated. </p>
