Unable to start RabbitMQ

erl

I have Googled so much, and not got any proper answer.So , I am posting this question for better result.

I have already killed the RabbitMQ server process .

Now when I am trying to start it again, it shows

Command

rabbitmqctl start_app

Error

{error_logger,{{2013,11,4},{11,26,8}},"Cookie file /ngs/app/ttet/.erlang.cookie must be accessible by owner only",[]}

Crash dump was written to: erl_crash.dump

Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}})

Erlang is running . Is it require to kill Erlang process.

[ttet@addr:17.566.98.656 Erlang]$:/ngs/app/ttet> ps -ef | grep erlang

This helped me:

chmod 600 ~/.erlang.cookie
rabbitmqctl start_app

You can use rabbitmqctl start_app only after you call rabbitmqctl stop_app. These commands starts/stops RabbitMQ application, not Erlang node. If you really killed RabbitMQ node you need to call rabbitmq-server to start RabbitMQ. Check is there RabbitMQ node running you can calling ps -ef | grep rabbit.

Also from your logs I figured out that the reason of errors is not appropriate .erlnag.cookie file access mode - {error_info,{exit,{"Cookie file /ngs/app/curot/.erlang.cookie must be accessible by owner only".... Try to change it chmod 600 /ngs/app/curot/.erlang.cookie and start RabbitMQ server again.

It is not require to kill Erlang epmd as it is a daemon that acts as a name server on all hosts involved in distributed Erlang computations and does not interfere on you RabbitMQ instance.

I have solved this.

First step is I have changed the permission to /ngs/app/curot/.erlang.cookie.

And 2nd step I used rabbitmq-server -detached command for start the rabbitmq.

Now its working for me.
