title: MongoDB service not starting on RedHat - missing 'service_uri'
body: <p>I'm on a <code>Red Hat Enterprise Linux Client release 5.4 (Tikanga)</code> machine</p>
  
  <p>I created my <code>/etc/yum.repos.d/10gen.repo</code> like this:</p>
  
  <pre><code>[10gen]
  name=10gen Repository
  baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
  gpgcheck=0
  enabled=1
  </code></pre>
  
  <p>I installed MongoDB with: <code>sudo yum install mongo-10gen mongo-10gen-server</code></p>
  
  <p>but when I run: <code>sudo service mongod start</code></p>
  
  <p>I get: <code>Missing SERVICE_URI environment variable</code></p>
  
  <p>help! :)</p>
