Hi all, i have some problem with my odoo server. 

1. my odoo server on linux work correctly before, but now it's won't start

2. i try to start my server service with commad :

​root@1aaax:~# ps aux | grep Odoo
root 23454 0.0 0.0 3296 724 pts/0 S+ 06:15 0:00 grep --color=auto Odoo

and i try to use this command too:

​root@1aaax:~# sudo service odoo-server start
Failed to start odoo-server.service: Unit odoo-server.service not found.

i don't know whats happen on my odoo.. because my odoo server was installed and cofigured by other person.
