:-:  RabbitMQ集群架構 <br/> 步驟如下： **1. 準備三臺安裝好RabbitMQ的機器**  **2. 修改三臺機器的主機名，分別命名為`node1`、`node2`、`node3`** ```shell # vim /etc/hostname ``` **3. 在三臺機器上都做如下主機映射** ```shell # vim /etc/hosts 192.168.0.109 node1 192.168.0.112 node2 192.168.0.113 node3 ``` **4. 重啟三臺機器** ```shell # reboot ``` **5. 讓三臺機器的cookie保證一致** ```shell -- 在node1節點執行下面的命令 # scp /var/lib/rabbitmq/.erlang.cookie root@node2:/var/lib/rabbitmq/.erlang.cookie # scp /var/lib/rabbitmq/.erlang.cookie root@node3:/var/lib/rabbitmq/.erlang.cookie ``` **6. 分別啟動三臺機器的RabbitMQ服務和Erlang虛擬機** ```shell # rabbitmq-server -detached ``` **7. 在node2節點執行下面的命令** ```shell # rabbitmqctl stop_app # rabbitmqctl reset # rabbitmqctl join_cluster rabbit@node1 # rabbitmqctl start_app ``` **8. 在node3節點執行下面的命令** ```shell # rabbitmqctl stop_app # rabbitmqctl reset # rabbitmqctl join_cluster rabbit@node2 # rabbitmqctl start_app ``` **9. 在任意一臺機器上執行`rabbitmqctl cluster_status`可以查看集群狀態** ```shell # rabbitmqctl cluster_status Cluster status of node rabbit@node1 ... Basics Cluster name: rabbit@node1 Disk Nodes rabbit@node1 rabbit@node2 rabbit@node3 Running Nodes rabbit@node1 rabbit@node2 rabbit@node3 Versions rabbit@node1: RabbitMQ 3.8.8 on Erlang 21.3 rabbit@node2: RabbitMQ 3.8.8 on Erlang 21.3 rabbit@node3: RabbitMQ 3.8.8 on Erlang 21.3 Maintenance status Node: rabbit@node1, status: not under maintenance Node: rabbit@node2, status: not under maintenance Node: rabbit@node3, status: not under maintenance ... ``` **10. 在任意一臺機器上創建用戶** ```shell # rabbitmqctl add_user admin admin # rabbitmqctl set_user_tags admin administrator # rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*" ``` **11. 登錄WEB界面** 使用任意節點的 ip 登錄，比如這里用node1的 ip：http://192.168.0.109:15672 登錄，用戶名一律為`admin`，密碼一律為`admin`。
