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",[]} {error_logger,{{2013,11,4},{11,26,8}},crash_report,[[{initial_call,{auth,init,['Argument__1']}}, {pid,<0.18.0>},{registered_name,[]},{error_info,{exit,{"Cookie file /ngs/app/curot/.erlang.cookie must be accessible by owner only",[{auth,init_cookie,0,[{file,"auth.erl"}, {line,285}]},{auth,init,1,[{file,"auth.erl"},{line,139}]},{gen_server,init_it,6,[{file,"gen_server.erl"},{line,297}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"}, {line,227}]}]},[{gen_server,init_it,6,[{file,"gen_server.erl"},{line,321}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,227}]}]}},{ancestors,[net_sup,kernel_sup,<0.9.0>]},{messages,[]},{links,[<0.16.0>]},{dictionary,[]},{trap_exit,true},{status,running},{heap_size,610},{stack_size,24},{reductions,401}],[]]} {error_logger,{{2013,11,4},{11,26,8}},supervisor_report,[{supervisor,{local,net_sup}}, {errorContext,start_error},{reason,{"Cookie file /ngs/app/ttet/.erlang.cookie must be accessible by owner only",[{auth,init_cookie,0,[{file,"auth.erl"},{line,285}]},{auth,init,1,[{file,"auth.erl"},{line,139}]},{gen_server,init_it,6,[{file,"gen_server.erl"},{line,297}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,227}]}]}},{offender,[{pid,undefined},{name,auth},{mfargs,{auth,start_link,[]}},{restart_type,permanent},{shutdown,2000},{child_type,worker}]}]} {error_logger,{{2013,11,4},{11,26,8}},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,{{2013,11,4},{11,26,8}},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,[]]}}})
Erlang is running . Is it require to kill Erlang process.
[ttet@addr:17.566.98.656 Erlang]$:/ngs/app/ttet> ps -ef | grep erlang

Answer
This helped me:
chmod 600 ~/.erlang.cookie
rabbitmqctl start_app
