FATAL:  could not create lock file "/tmp/.s.PGSQL.5432.lock": Permission denied

Cause

The permissions of /tmp were changed from 777 to something less open; for example, 755.  

When Postgres starts it creates a lock file under /tmp, as a postgres user. The current permission on /tmp does not allow the lock file to be created.

Resolution

  1. Change the permission of /tmp to 777: chmod 777 /tmp
  2. Run the NMC configuration script: /opt/lgtonmc/bin/nmc_config
