Make sure `` pair is present inside the /etc/hosts file. else, add the entry and restart pbs. If that doesn’t work you can check $PBS\_HOME/datastore/pg\_log/ and $PBS\_HOME/server\_logs/ to debug it further. ---

Thank you for replying, nithinj I don’t know whether it has an influence,I was installing PBS pro on a virtual machine, /etc/hosts file add line like this: > 127.0.0.1 localhost > 10.154.55.178 centos7-801.novalocal centos7-801 In addition, what do you mean by “add the entry”? ---

And I just checked the $PBS\_HOME/datastore/pg\_log as you said, it seems that the database has something wrong with schema “pbs” does not exist… > 2017-08-01 03:39:58 CESTLOG: database system was shut down at 2017-08-01 03:39:58 CEST > 2017-08-01 03:39:58 CESTLOG: database system is ready to accept connections > 2017-08-01 03:39:58 CESTLOG: autovacuum launcher started > 2017-08-01 03:39:59 CESTERROR: schema “pbs” does not exist > 2017-08-01 03:39:59 CESTSTATEMENT: /\* > \* … > \*/ > drop schema pbs cascade; > 2017-08-01 03:42:08 CESTLOG: received smart shutdown request > 2017-08-01 03:42:08 CESTLOG: autovacuum launcher shutting down > 2017-08-01 03:42:08 CESTLOG: shutting down > 2017-08-01 03:42:08 CESTLOG: database system is shut down > 2017-08-01 03:42:09 CESTLOG: database system was shut down at 2017-08-01 03:42:08 CEST > 2017-08-01 03:42:09 CESTLOG: database system is ready to accept connections > 2017-08-01 03:42:09 CESTLOG: autovacuum launcher started ---

Hi, nithinj As you said, I checked the $PBS\_HOME/datastore/pg\_log/ and $PBS\_HOME/server\_logs/ and then I found the dataservice of PBS isn’t startup successfully. And then I searched, finally found the upgrade issue is due to the firewall… Shutdown the firewall of the system and then PBS can work well~ Appreciate for your advice again, it helps a lot~
