Description of problem: rdo-manager documentation says that the hostname must be resolvable and if no dns is in use to modify /etc/hosts however, it only says Baremetal Ensure that there is a FQDN hostname set and that the $HOSTNAME environment variable matches that value. problem is with rabbitmq connecting to `hostname -s` values so if the hostname -f is rdo.redhat.com, rabbitmq will only connect to rabbit@rdo if it cannot resolve rdo from dns or hosts file then everything stops. for more info see: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/653405 Version-Release number of selected component (if applicable): How reproducible: every time Steps to Reproduce: 1.follow the doc 2. 3. Actual results: crash Expected results: it works Additional info:
so /etc/hosts should have something like this, however you want to word it 127.0.0.1 hostname.f.q.d.n hostname OR 127.0.0.1 myhost.mydomain myhost
