title: Not able to Start rabbitmq server in centos 7 using systemctl
body: <p>I am trying to start the rabbitmq server in centos 7. I installed erlang as it is a dependency to rabbitmq-server. Package erlang.x86_64 0:R16B-03.7.el7 .I then Installed rabbitmq using package rabbitmq-server-3.2.2-1.noarch.rpm. Installation was successful. I enabled management console uisng rabbitmq-plugins enable rabbitmq_management. But while starting the service rabbitmq-server it fails. </p>
  
  <pre><code>[root@tve-centos ~]# systemctl start rabbitmq-server.service
  Job for rabbitmq-server.service failed. See 'systemctl status rabbitmq-server.service' and 'journalctl -xn' for details.
  [root@tve-centos ~]# systemctl status rabbitmq-server.service
