无法使用systemctl在centos 7中启动rabbitmq服务器

我试图在centos 7中启动rabbitmq服务器.我安装了erlang,因为它是对rabbitmq-server的依赖.软件包erlang.x86_64 0：R16B-03.7.el7.然后使用包rabbitmq-server-3.2.2-1.noarch.rpm安装rabbitmq.安装成功我启用了管理控制台uisng rabbitmq-plugins启用rabbitmq_management.但是在启动服务的时候,它会失败.

[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

===========

Error description:
   {Could_not_start,rabbitmq_management,{Could_not_start_listener,[{port,15672}],eacces}}

Log files (may contain more information):
   /var/log/rabbitmq/rabbit@tve-centos.log
   /var/log/rabbitmq/rabbit@tve-centos-sasl.log

但没有进程使用端口15672

但是,如果我尝试使用/usr/sbin / rabbitmq-server启动它.我成功启动了该服务.但是我的要求是使用systemctl启动它.

systemctl stop firewalld
systemctl disable firewalld

SELINUX=disabled
