[rabbitmq-discuss] Problem installing RabbitMQ with Puppet on CentOS 6.2

Fri Oct 5 10:45:57 BST 2012

Hmm. There's nothing very obvious that I can think of. I've looked in 
the OTP source and that message really only appears if HOME is not set.

Things you might try:

* Run /usr/lib/rabbitmq/bin/rabbitmq-plugins instead, to remove a 
wrapper script

* Edit /usr/lib/rabbitmq/bin/rabbitmq-plugins to insert "echo $HOME" 
just before "exec erl", see if it's really set at that point.

* If all else fails, edit the enabled plugins file directly rather than 
invoking rabbitmq-plugins. Set the contents of 
/etc/rabbitmq/enabled_plugins to exactly the string:

[rabbitmq_management].

including the full stop.

Cheers, Simon
