RabbitMQ平常集群搭建指南

RabbitMQ平常集群搭建指南

   本文已经完全迁移至，www.geekery.cn 后续不在此更新
  目标架构

本次搭建的目标是构建一个由三个节点构成的RabbitMQ集群，节点信息如下：

• rabbit02: IP地点 192.168.10.132
  
• rabbit03: IP地点 192.168.10.133
  
• rabbit04: IP地点 192.168.10.134
  

准备工作

在开始之前，确保全部节点上都已安装RabbitMQ Server。假如尚未安装，可以通过以下下令进行安装：

1. yum install -y epel-release
2. yum install -y rabbitmq-server

复制代码

同时，设置主机名和修改/etc/hosts文件以正确剖析各节点的名称。
同步.erlang.cookie

为了答应节点间通信，需要确保全部节点上的.erlang.cookie文件内容相同。使用以下下令从rabbit02节点复制cookie到其他节点

1. [root@rabbit02 ~]# scp /var/lib/rabbitmq/.erlang.cookie rabbit03:/var/lib/rabbitmq/
2. The authenticity of host 'rabbit03 (192.168.10.133)' can't be established.
3. ECDSA key fingerprint is SHA256:ImtbIE2DzY9M7yqwTDfMn3EzHOjk0CGowUigMe00exk.
4. ECDSA key fingerprint is MD5:23:d8:46:37:71:8b:e3:56:d1:48:d4:f5:a9:64:80:f0.
5. Are you sure you want to continue connecting (yes/no)? yes
6. Warning: Permanently added 'rabbit03,192.168.10.133' (ECDSA) to the list of known hosts.
7. root@rabbit03's password:
8. .erlang.cookie                                                                                                                                             100%   20    24.5KB/s   00:00   
9. [root@rabbit02 ~]# scp /var/lib/rabbitmq/.erlang.cookie rabbit04:/var/lib/rabbitmq/
10. The authenticity of host 'rabbit04 (192.168.10.134)' can't be established.
11. ECDSA key fingerprint is SHA256:ImtbIE2DzY9M7yqwTDfMn3EzHOjk0CGowUigMe00exk.
12. ECDSA key fingerprint is MD5:23:d8:46:37:71:8b:e3:56:d1:48:d4:f5:a9:64:80:f0.
13. Are you sure you want to continue connecting (yes/no)? yes
14. Warning: Permanently added 'rabbit04,192.168.10.134' (ECDSA) to the list of known hosts.
15. root@rabbit04's password:
16. .erlang.cookie                                                                                                                                             100%   20    21.1KB/s   00:00   
17. [root@rabbit02 ~]#

复制代码

集群设置

在rabbit03和rabbit04上执行以下步调：

1. [root@rabbit03 ~]# rabbitmqctl stop_app
2. Stopping node rabbit@rabbit03 ...
3. ...done.
4. [root@rabbit03 ~]# rabbitmqctl reset
5. Resetting node rabbit@rabbit03 ...
6. ...done.
7. [root@rabbit03 ~]# systemctl stop firewalld
8. [root@rabbit03 ~]# rabbitmqctl join_cluster --ram rabbit@rabbit02
9. Clustering node rabbit@rabbit03 with rabbit@rabbit02 ...
10. ...done.

复制代码

1. [root@rabbit04 ~]# rabbitmqctl stop_app
2. Stopping node rabbit@rabbit04 ...
3. ...done.
4. [root@rabbit04 ~]# systemctl stop firewalld
5. [root@rabbit04 ~]# rabbitmqctl stop_app
6. Stopping node rabbit@rabbit04 ...
7. ...done.
8. [root@rabbit04 ~]# rabbitmqctl reset
9. Resetting node rabbit@rabbit04 ...
10. ...done.
11. [root@rabbit04 ~]# rabbitmqctl join_cluster --ram rabbit@rabbit02
12. Clustering node rabbit@rabbit04 with rabbit@rabbit02 ...
13. ...done.

复制代码

最终确认

在rabbit02上执行以下步调来确认集群状态：
这表明集群已经成功建立，并且rabbit02作为磁盘节点，rabbit03和rabbit04作为RAM节点加入了集群。

1. [root@rabbit02 ~]# rabbitmqctl cluster_status
2. Cluster status of node rabbit@rabbit02 ...
3. [{nodes,[{disc,[rabbit@rabbit02]},{ram,[rabbit@rabbit04,rabbit@rabbit03]}]},
4. {running_nodes,[rabbit@rabbit02]},
5. {cluster_name,<<"rabbit@rabbit02">>},
6. {partitions,[]}]
7. ...done.
8. [root@rabbit02 ~]#
10. [root@rabbit03 ~]# rabbitmqctl cluster_status
11. Cluster status of node rabbit@rabbit03 ...
12. [{nodes,[{disc,[rabbit@rabbit02]},{ram,[rabbit@rabbit03]}]}]
13. ...done.
14. [root@rabbit03 ~]#
16. [root@rabbit03 ~]# rabbitmqctl cluster_status
17. Cluster status of node rabbit@rabbit03 ...
18. [{nodes,[{disc,[rabbit@rabbit02]},{ram,[rabbit@rabbit03]}]}]
19. ...done.
