On lion OS, after installation, when running, error happens.
At first, not using rabbitmq-env.config file, starting by "sudo rabbitmq-server", the following message shows:

yus-iMac:rabbitmq yuchen$ sudo rabbitmq-server
Activating RabbitMQ plugins ...

********************************************************************************
********************************************************************************

0 plugins activated:

ERROR: epmd error for host "yus-iMac": address (unable to establish tcp connection)

Then I add rabbitmq-env.conf file. The content is as follows:

RABBITMQ_NODENAME=rabbitb@yus-iMac.local

When starting, another error message is given:

yus-iMac:rabbitmq yuchen$ sudo rabbitmq-server
Activating RabbitMQ plugins ...

********************************************************************************
********************************************************************************

0 plugins activated:

{error_logger,{{2012,5,26},{21,47,13}},"Can't set short node name!\n Please check your configuration\n",[]}

I think the message means short node can’t be used. But I don’t know how to control rabbitmq-server for using name, rather than sname?

    Search on Google found this link, which should fix the problem you see at the beginning.
    Here’s the relevant part in case it become inaccessible:

    making sure that your machine name (rs-mbp in my case) is in /private/etc/hosts

    ##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost rs-mbp
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost
