Here is the init script for Nginx while we are going to use with Phusion Passenger on ubuntu. I have used it on Ubuntu 12.04 LTS.

Create a file "/etc/init.d/nignx" and add below code into it.   
      vim  /etc/init.d/nignx

Then add nginx into update-rc.d for start nginx whenever system boot,
      update-rc.d nginx defaults

Make that file executable by changing permission,
       chmod   +x  /etc/init.d/nignx

For converting .crt file to .pem

	openssl x509 -in mycert.crt -out mycert.der -outform DER

You would then take the output of that, (i.e. mycert.der) and call:

	openssl x509 -in mycert.der -inform DER -out mycert.pem -outform PEM
