docker 部署 rabbitmq 集群

单机部署

docker run -id -p 15672:15672 -p 56732:5672 \
--name rabbitmq \
--restart always \
-v /docker/rabbitmq:/var/lib/rabbitmq \
-e RABBITMQ_DEFAULT_USER=admin \
-e RABBITMQ_DEFAULT_PASS=****** \
rabbitmq:3.12.0-management

集群部署

#node01
docker run -id -p 15673:15672 -p 5673:5672 \
--name rabbitmqNode01 \
--hostname=node01 \
--restart always \
-v /docker/rabbitmqCluster/rabbitmq01:/var/lib/rabbitmq \
-e RABBITMQ_DEFAULT_USER=admin \
-e RABBITMQ_DEFAULT_PASS=****** \
rabbitmq:3.12.0-management

# 把rabbitmqNode01容器中的/var/lib/rabbitmq/.erlang.cookie复制到宿主机中储存
# 集群.erlang.cookie需要一致

#node02
docker run -id -p 15674:15672 -p 5674:5672 \
--name rabbitmqNode02 \
--hostname=node02 \
--restart always \
--link rabbitmqNode01:node01 \
-v /xfgit/docker/rabbitmqCluster/rabbitmq02:/var/lib/rabbitmq \
-e RABBITMQ_DEFAULT_USER=admin \
-e RABBITMQ_DEFAULT_PASS=****** \
rabbitmq:3.12.0-management

#node03
docker run -id -p 15675:15672 -p 5675:5672 \
--name rabbitmqNode03 \
--hostname=node03 \
--restart always \
--link rabbitmqNode01:node01 \
--link rabbitmqNode02:node02 \
-v /Users/px/Documents/home/xfgit/docker/rabbitmqCluster/rabbitmq03:/var/lib/rabbitmq \

集群设置

# 进入第一个rabbitmq节点容器
docker exec -it rabbitmqNode01 /bin/bash
# rabbitmqctl stop 会将 Erlang 虚拟机关闭，rabbitmqctl stop_app只关闭RabbitMQ 服务
rabbitmqctl stop_app
# 重置节点，将 RabbitMQ 节点返回到其原始状态。
rabbitmqctl reset
# 只启动应用服务
rabbitmqctl start_app
# 退出容器
exit

# 进入第二个rabbitmq节点容器
docker exec -it rabbitmqNode02 /bin/bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@node01
rabbitmqctl start_app
exit

# 进入第三个rabbitmq节点容器
docker exec -it rabbitmqNode03 /bin/bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@node01
rabbitmqctl start_app
exit

3.查看集群状态
# 进入任一节点容器
docker exec -it rabbitmqNode01 /bin/bash
命令查看
rabbitmqctl cluster_status

4.访问以下任意一个登录查看
http://host-ip:15673
http://host-ip:15674
http://host-ip:15675
