REDHAT7安装rabbitMQ

几年前写过在Linux上安装rabbitMQ,今年在新项目安装时发现之前写的方法在RedHat7版本以上已经不适用了，记录下新的安装方式

准备rpm包

1. 下载erlang
   下载地址：http://www.rabbitmq.com/releases/erlang/erlang-19.0.4-1.el7.centos.x86_64.rpm

2. 下载rabbitmq
   下载地址：http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.6/rabbitmq-server-3.6.6-1.el7.noarch.rpm

安装

1. 安装erlang

[root@localhost1 rabbitMQ]# rpm -ivh erlang-19.0.4-1.el7.centos.x86_64.rpm

测试erlang

[root@localhost1 rabbitMQ]# erl

3. 安装rabbitMQ

[root@localhost1 rabbitMQ]# rpm -ivh rabbitmq-server-3.6.6-1.el7.noarch.rpm

启动

[root@localhost1 rabbitMQ]# systemctl start rabbitmq-server
Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

分析是权限问题，解决方式↓

[root@localhost1 rabbitMQ]# cd /var/lib/rabbitmq/
[root@localhost1 rabbitmq]# chmod +x .erlang.cookie

再次启动

[root@localhost1 rabbitmq]# systemctl status rabbitmq-server.service -l

新的问题，解决如下↓

[root@localhost1 rabbitmq]# chown rabbitmq:rabbitmq .erlang.cookie
[root@localhost1 rabbitmq]# chmod 400 .erlang.cookie

这次启动成功

问题

成功启动之后，查看rabbitmq状态

[root@localhost1 rabbitmq]# rabbitmqctl status
Status of node rabbit@localhost1 ...
Error: unable to connect to node rabbit@localhost1: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@localhost1]

rabbit@localhost1:
  * connected to epmd (port 4369) on localhost1
  * epmd reports node 'rabbit' running on port 25677
  * TCP connection succeeded but Erlang distribution failed
  * suggestion: hostname mismatch?
  * suggestion: is the cookie set correctly?
  * suggestion: is the Erlang distribution using TLS?

current node details:
- node name: '[email protected]'
- home dir: /var/lib/rabbitmq
- cookie hash: 54z9Im3dJwLrD3ph+T4UHQ==

原因是这台服务器之前装过rabbitmq，关闭卸载的时候没有清理干净
