主节点 120 执行
#docker run -d --restart=always --net host --hostname rabbit1 --name myrabbit1  -v /data/rabbitmq/rabbit-docker-hosts:/etc/hosts -v /data/rabbitmq/rabbit-docker-database:/var/lib/rabbitmq -e RABBITMQ_ERLANG_COOKIE='rabbitcookie'  rabbitmq:3.8.5-management
从节点 121 执行
#docker run -d --restart=always --net host --hostname rabbit2 --name myrabbit2  -v /data/rabbitmq/rabbit-docker-hosts:/etc/hosts -v /data/rabbitmq/rabbit-docker-database:/var/lib/rabbitmq -e RABBITMQ_ERLANG_COOKIE='rabbitcookie'  rabbitmq:3.8.5-management

4. 加入集群

#docker exec -it myrabbit2 bash # 进入镜像命令行
#rabbitmqctl stop_app
//rabbitmqctl reset
#rabbitmqctl join_cluster rabbit@rabbit1 #rabbit1为主节点的hostname
#rabbitmqctl start_app
#rabbitmq-plugins enable rabbitmq_management

5. 权限初始化

rabbitmqctl stop_app

rabbitmq 查看所有队列信息
rabbitmqctl list_queues

还原 rabbitmq 清除所有队列
rabbitmqctl reset

rabbitmq 查看用户
rabbitmqctl list_users

rabbitmq添加用户
rabbitmqctl add_user root root

rabbitmq设置权限
rabbitmqctl set_permissions -p / root ".*" ".*" ".*"

rabbitmq查看集群状态信息
rabbitmqctl cluster_status

移除某个集群节点：一般情况当节点故障时，在正常的节点中，移除该故障节点
rabbitmqctl  -n rabbit@rabbit1 forget_cluster_node rabbit@rabbit3
