unable to start rabbitmq-server

Question

I installed rabbitmq using homebrew. I am trying to start rabbitmq server but I always get this error which I am unable to figure out why!

I have erlang installed and there is no other application running on the same port.

$ rabbitmq-server 
{error_logger,{{2013,2,11},{22,37,49}},"Can't set short node name!\nPlease check your configuration\n",[]}
{error_logger,{{2013,2,11},{22,37,49}},crash_report,[[{initial_call,{net_kernel,init,['Argument__1']}},{pid,},{registered_name,[]},{error_info,{exit,{error,badarg},[{gen_server,init_it,6,[{file,"gen_server.erl"},{line,320}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,227}]}]}},{ancestors,[net_sup,kernel_sup,]},{messages,[]},{links,[]},{dictionary,[{longnames,false}]},{trap_exit,true},{status,running},{heap_size,610},{stack_size,24},{reductions,249}],[]]}
{error_logger,{{2013,2,11},{22,37,49}},supervisor_report,[{supervisor,{local,net_sup}},{errorContext,start_error},{reason,{'EXIT',nodistribution}},{offender,[{pid,undefined},{name,net_kernel},{mfargs,{net_kernel,start_link,[[rabbitmqprelaunch1593,shortnames]]}},{restart_type,permanent},{shutdown,2000},{child_type,worker}]}]}
{error_logger,{{2013,2,11},{22,37,49}},supervisor_report,[{supervisor,{local,kernel_sup}},{errorContext,start_error},{reason,shutdown},{offender,[{pid,undefined},{name,net_sup},{mfargs,{erl_distribution,start_link,[]}},{restart_type,permanent},{shutdown,infinity},{child_type,supervisor}]}]}
{error_logger,{{2013,2,11},{22,37,49}},std_info,[{application,kernel},{exited,{shutdown,{kernel,start,[normal,[]]}}},{type,permanent}]}
{"Kernel pid terminated",application_controller,"{application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}}"}

Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})

btw, erl -sname abc gives the same output

Update:

This is what I have in /etc/hosts

127.0.0.1   localhost
255.255.255.255 broadcasthost

did u eventually get this working? running into the exact same issue and spent the past hour looking for it. no one else seems to have the same issues. — chourobin

check your computer name and your short host name or alias name in /etc/hosts, match this

Check your computer name [wendy@nyc123]$ nyc123 is your computer name
Check your short hostname

[wendy@nyc123]$ hostname -s
[wendy@nyc123]$ nyc456

This error could happen because your computer name and short host name didn't match. To match this, you can change the computer hostname or alias name.

Change computer host name

[wendy@nyc123]$ hostname nyc456
close your terminal and open again [wendy@nyc456]$ the computer name has changed

or

Change alias name in /etc/hosts

127.0.0.1 nyc123.com nyc123
save and check again
[wendy@nyc123]$ hostname -s
[wendy@nyc123]$ nyc123

Restart your rabbitmq!

[root@nyc123]$ rabbitmq-server start</p>
