运行环境

操作系统/软件

版本

Linux xxxx3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

CentOS 7.x

erlang-21.3-1.el7.x86_64

21.3-1

rabbitmq-server-3.8.8-1.el7.noarch

3.8.8-1

原因分析

根据报错日志，常见原因有两个：

1. erlang未安装 ，导致启动报错；
   先检查erlang是否已安装：
   ①.rpm -qa | grep erlang

   [root@xxxx /]# rpm -qa|grep erlang
   erlang-21.3-1.el7.x86_64
   1
   2

   如果未安装erlang，则不会显示类似“erlang-21.3-1.el7.x86_64”的结果

2. host文件配置问题 ，导致mq启动时读取不到；

   [root@xxxx /]# vim /etc/hosts
   
   127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
   ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
   192.168.38.110 xxxx
   1
   2
   3
   4
   5

   如果hosts文件中，未添加ip-主机名的映射，则添加即可。
   备注：
   获取主机名：

   [root@xxxx /]# hostname
   xxxx
   1
   2

   xxxx 即主机名

[root@xxxx /]# systemctl restart rabbitmq-server 
[root@xxxx /]# systemctl status rabbitmq-server
