Add a status section to the initscript file

Hi
Sorry for my english I'm French.

I have added a status section to the script since I would to see which pid is used by the process, it could be useful. Furthermore I added a new Centos way to add that script at startup.
This is my first pullrequest, probably i'm missing something, I'm more able to share my work by patch as i done often in the sme server project.

Please correct me if i'm doing something wrong
