Unable to start rabbitmq-server

erlangrabbitmq

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 

Best Solution

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>
