When I start PBS, only pbs_sched runs

I followed INSTALL from openpbs/INSTALL at master · openpbs/openpbs · GitHub, and I got some troubles on “13. Start the PBS services.”

I add some information about my situation.

OS: Ubuntu 20.04
PBS version: 20.0.0

How can I treat “Could not find any usable IP address for host” in the server_logs?

Please check the below:

  1. DNS and /etc/hosts should be working and same across all the nodes
  2. static IP and hostname is a must for all the systems in the PBS clusters
  3. SELinux disabled and system restarted
  4. firewall allowing ports 15001 to 15007 and 17001
  5. NTP configured

I only use a single node, and do I have to consider other things?

I checked your list and there is no problem. @adarsh
