title: MongoDB setup: mongo.log permissions wrong?
body: <p>First time Mongo user here running OSX Mountain Lion.</p>
  
  <p>Installed MongoDB via homebrew. Upon typing mongod I get the following message:</p>
  
  <pre><code>$ mongod
  all output going to: /usr/local/var/log/mongodb/mongo.log
  can't open [/usr/local/var/log/mongodb/mongo.log] for log file: errno:13 Permission denied
  </code></pre>
  
  <p>What is the correct command to apply permissions to my mongodb folder? I am the admin user on my computer.</p>
