[rabbitmq-discuss] Unable to get automatic clustering to work

[Mark J. Reed]

OK, I'm having better luck with 2.2.   But I still have a few
instances where one node can't talk to another, even though TCP
connectivity is there.  Any help diagnosing those?

rabbit1$ rabbitmqctl status
Status of node rabbit at rabbit1 ...
[{running_applications,[{rabbit,"RabbitMQ","2.2.0"},
                        {mnesia,"MNESIA  CXC 138 12","4.4.12"},
                        {os_mon,"CPO  CXC 138 46","2.2.4"},
                        {sasl,"SASL  CXC 138 11","2.1.8"},
                        {stdlib,"ERTS  CXC 138 10","1.16.4"},
                        {kernel,"ERTS  CXC 138 10","2.13.4"}]},
 {nodes,[{disc,[rabbit at rabbit1]}]},
 {running_nodes,[rabbit at rabbit1]}]
...done.

rabbit1$ rabbitmqctl -n rabbit at rabbit2 status  # 1 can see 2
