[rabbitmq-discuss] Problem running rabbit broker

Sun Jun 1 17:12:47 BST 2008

Ah - a typo. What I should have written is

# chown *-R *rabbitmq:rabbitmq /var/log/rabbitmq
# chown *-R* rabbitmq:rabbitmq /var/lib/rabbitmq

Another clue (which I missed on the first reading of your reply) is:

{"init terminating in do_boot",{undef,[{mnesia ,system_info,[directory]},{*
rabbit_mnesia,ensure_mnesia_dir,0*
},{rabbit,start,0},{init,start_it,1},{init,start_em,1}]}}

Looks as if the Mnesia directory was either not created or was created with
the wrong ownership/permissions.
If all else fails, my recommendations in your case are to rm -rf
/var/lib/rabbitmq, re-create it with the proper permissions as mentioned in
my previous email, ensure any other Rabbit directories have the right
permissions,  and start the broker again.
