I was unable to run PBS server on my CentOS 7.2 machine.
`systemctl start pbs && systemctl status pbs` shows it successfully started.

However, within just 5 secs, the service was automatically shut down, `systemctl status pbs`:

I’ve tried disabling the selinux, but it doesn’t work.

Hi,
Could you please share the pbs.conf file and the server logs.
Thanks.

Hi,
It seems you are using localhost.localdomain for server and this hostname being mapped to loopback
address(127.0.0.\*) in /etc/hosts. Please setup a network, with hostname of machine mapped to a network IP.
Regards
Dilip

Thanks! That solves my problem. I was testing the server without internet connection, and do not have a DNS server to resolve my hostname. Now I just use plain IP address anywhere. It seems to work!
