Hello community

I am facing an issue when trying to start odoo service on Centos 7.6 with below command

systemctl start odoo
I get the below error. 

Feb 28 10:46:06 DEVAPPSVR odoo[11321]: Starting Odoo Server Daemon (odoo-server): [ OK ]
Feb 28 10:46:06 DEVAPPSVR systemd[1]: Can't open PID file /var/run/odoo/odoo-server.pid (yet?) after start: No such file or directory

Feb 28 10:46:06 DEVAPPSVR systemd[1]: Unit odoo.service entered failed state.

I checked the said module in the packages directory and it was there with the following files

drwxr-x--- 2 root root 45 Feb 28 08:40 extern
-rw-r----- 1 root root 108349 Feb 28 08:40 __init__.py

-rw-r----- 1 root root 758 Feb 28 08:40 py31compat.pyc

I also confirmed that my installation meets requirements in the requirements.txt file
