【RabbitMQ】14 集群搭建

 

多服务器单实例 —— 参考博客:

https://www.cnblogs.com/lixioayi/articles/9993658.html

首先要找到cookie文件,所有实例要保持cookie一致(启动运行过的RabbitMQ会生成):

[root@localhost ~]# find / -name .erlang.cookie
/var/lib/rabbitmq/.erlang.cookie
[root@localhost ~]#

里面查看就是一堆字母:

[root@localhost ~]# cat /var/lib/rabbitmq/.erlang.cookie
RMSWWJGQNKZKNEILPSHS[root@localhost ~]# 

然后选定主从关系,统一使用主实例的Cookie

cookie是一个只读文件,那就用SCP直接传输覆盖吧(从机记得先关闭服务)

[root@localhost ~]# scp /var/lib/rabbitmq/.erlang.cookie root@192.168.2.110:/var/lib/rabbitmq/
The authenticity of host '192.168.2.110 (192.168.2.110)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.2.110' (ECDSA) to the list of known hosts.
root@192.168.2.110's password: 
.erlang.cookie                                                                                                                                                                 100%   20    58.1KB/s   00:00    
[root@localhost ~]# 

 

对每一个Cookie控制读写权限:

chmod 600 /var/lib/rabbitmq/.erlang.cookie

然后开启每台机器的服务

service rabbitmq-server start

 

其中 2 和 3 从机 关闭应用,不是关闭服务

rabbitmqctl stop_app

 

然后2和3都加入到1中去

rabbitmqctl join_cluster rabbit@centos6-1

 

启动2和3的应用

rabbitmqctl start_app
