centos 7.x yum安装rabbitmq-server，启动报错解决方法

发布时间：01/15 来源：浏览：关键词：

MQ全称为Message Queue, 消息队列（MQ）是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息（针对应用程序的数据）来通信，而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信，而不是通过直接调用彼此来通信，直接调用通常是用于诸如远程过程调用的技术。

yum安装好rabbitmq-server后，启动报错

解决办法：

firewall-cmd --permanent --add-port=5672/tcp
firewall-cmd --reload
setsebool -P nis_enabled 1

或者粗暴点的办法（不推荐）

systemctl stop firewalld
systemctl disable firewalld
setenforce 0 （记得/etc/selinux/config也改成 disable，否则重启就不生效了）
