[rabbitmq-discuss] Problem with using rabbitmqctl on EC2

Mon Feb 27 03:00:15 GMT 2012

Hi Experts

I have installed RabbitMQ 2.7.1 on EC2 (host name is ec2test2) and
server getting started without any issue.

AMQP 0-9-1 / 0-9 / 0-8
Copyright (C) 2007-2011 VMware, Inc.

node           : rabbit at ec2test2
app descriptor : /app/rabbitmq_server-2.7.1/sbin/../ebin/rabbit.app
home dir       : /root
config file(s) : (none)
cookie hash    : 4lZvwoYL5ZJbkEiBx9CgDA==
log            : /var/log/rabbitmq/rabbit at ec2test2.log
sasl log       : /var/log/rabbitmq/rabbit at ec2test2-sasl.log
database dir   : /app/rabbitmq-config/lib/rabbitmq/mnesia/
rabbit at ec2test2
erlang version : 5.9

But when I try to use rabbitmqctl, I am getting the below error.

ec2test2:/app/rabbitmq/sbin # sh rabbitmqctl
{error_logger,{{2012,2,27},{2,55,8}},"Can't set long node name!
\nPlease check your configuration\n",[]}
{error_logger,{{2012,2,27},{2,55,8}},crash_report,[[{initial_call,
{net_kernel,init,['Argument__1']}},{pid,<0.20.0>},{registered_name,[]},
{error_info,{exit,{error,badarg},[{gen_server,init_it,6,
[{file,"gen_server.erl"},{line,313}]},{proc_lib,init_p_do_apply,3,
[{file,"proc_lib.erl"},{line,227}]}]}},{ancestors,
[net_sup,kernel_sup,<0.9.0>]},{messages,[]},{links,[<0.17.0>]},
{dictionary,[{longnames,true}]},{trap_exit,true},{status,running},
{heap_size,6765},{stack_size,24},{reductions,2361}],[]]}

Host name is correctly configured and it displays:
ec2test2:/app/rabbitmq/sbin # hostname
ec2test2
ec2test2:/app/rabbitmq/sbin #

Could someone please explain this erroneous behavior?

Thanks.
