rabbitmq_managementを使うとRabbitMQの起動ができない

環境

• CentOS 7.1
• Erlang R16B03
• RabbitMQ 3.2.1

問題

RabbitMQをsystemctlで起動しようとすると失敗する。

systemctlでのメッセージはこんな感じ。

$ sudo systemctl status rabbitmq-server
rabbitmq-server.service - LSB: Enable AMQP service provided by RabbitMQ broker
   Loaded: loaded (/etc/rc.d/init.d/rabbitmq-server)
   Active: failed (Result: exit-code) since 火 2015-12-01 22:40:20 EST; 20min ago

/var/log/rabbitmq/startup_logのログはこんな感じ。

 cat /var/log/rabbitmq/startup_log

BOOT FAILED
===========

Error description:
   {could_not_start,rabbitmq_management,
                    {could_not_start_listener,[{port,15672}],eacces}}

Log files (may contain more information):
   /var/log/rabbitmq/[e-mail]
   /var/log/rabbitmq/[e-mail]

{"init terminating in do_boot",{rabbit,failure_during_boot,{could_not_start,rabbitmq_management,{could_not_start_listener,[{port,15672}],eacces}}}}

原因

selinuxでした。

解決策

selinuxを無効化してやればいいです。

$ sudo setenforce 0
$ sudo sed -i "/SELINUX/s/enforcing/disabled/g" /etc/selinux/config
