title: How to make MongoDB Server start on Linux Startup (CentOS)
body: <p>I'm using Linux CentOS 5.4, I installed MongoDB now it's availabled as a Daemon and Service </p>
  
  <p>When I execute service mongod start is says : [OK] --> in green as if the service started but when I try to connect to it I find it not working.</p>
  
  <p>but when I try to run "mongod" from the shell normally it starts but if I closed the shell connections it stops.</p>
  
  <p>how do I add it to the start up of the OS ? or how do I run it in the background ?</p>
