[rabbitmq-discuss] Plugins not starting?

[Russell Borogove]

1.6.0 on Ubuntu. 

I'm trying to run the managment plugin. 

I found /usr/lib/erlang/lib/rabbitmq_server-1.6.0, created a plugins directory, and downloaded the .ez files into it. 

After restarting rabbit, I'm not seeing a listen port on 55672, and rabbitmqctl status doesn't show the plugins:
Status of node 'rabbit at ip-10-162-102-179' ...
[{running_applications,[{rabbit,"RabbitMQ","1.6.0"},
                        {mnesia,"MNESIA  CXC 138 12","4.4.10"},
                        {os_mon,"CPO  CXC 138 46","2.2.2"},
                        {sasl,"SASL  CXC 138 11","2.1.6"},
                        {stdlib,"ERTS  CXC 138 10","1.16.2"},
                        {kernel,"ERTS  CXC 138 10","2.13.2"}]},
 {nodes,['rabbit at ip-10-162-102-179']},
 {running_nodes,['rabbit at ip-10-162-102-179']}]

I also added this line to /etc/rabbitmq/rabbitmq.conf:
PLUGINS_DIR=/usr/lib/erlang/lib/rabbitmq_server-1.6.0/plugins

I see no mention of plugins and nothing else interesting in the startup_log. 

Fishing-lesson questions:
* How do I know if rabbitmq.conf is being read?
* How can I tell what environment variables are set on a running instance of rabbit?
