本次使用单机docker集群部署，docker安装详情其他文档

集群部署

拉取镜像

1	`docker pull rabbitmq:3.7-management`

创建映射卷

docker volume create rabbitmq01
docker volume create rabbitmq02
docker volume create rabbitmq03
docker volume list

启动容器

节点1

1	`docker run -d --hostname rabbitmq01 --name rabbitmqCluster01 -v rabbitmq01:/var/lib/rabbitmq -p 15673:15672 -p 5673:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie' rabbitmq:3.7-management`

节点2

docker run -d --hostname rabbitmq02 --name rabbitmqCluster02 -v rabbitmq02:/var/lib/rabbitmq -p 15674:15672 -p 5674:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie'  --link rabbitmqCluster01:rabbitmq01 rabbitmq:3.7-management

节点3

docker run -d --hostname rabbitmq03 --name rabbitmqCluster03 -v rabbitmq03:/var/lib/rabbitmq -p 15675:15672 -p 5675:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie'  --link rabbitmqCluster01:rabbitmq01 --link rabbitmqCluster02:rabbitmq02  rabbitmq:3.7-management

查询容器启动情况 up为启动成功

1	`docker ps`

注： –hostname 设置容器的主机名RABBITMQ_ERLANG_COOKIE 节点认证作用，部署集成时需要同步该值

启动容器成功后，可以访问

192.168.117.151:15674
192.168.117.151:15675

账号/密码 guest / guest

登陆后，查看overviewTab页，可看到节点信息。

容器节点加入集群

容器1

1	`docker exec -it rabbitmqCluster01 bash`

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
exit

容器2

1	`docker exec -it rabbitmqCluster02 bash`

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbitmq01
rabbitmqctl start_app
exit

容器3

1	`docker exec -it rabbitmqCluster03 bash`

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbitmq01
rabbitmqctl start_app
exit

执行上述操作，这时候再查看 http://192.168.117.151:15673/#/的overview面板中的Nodes信息，可查看到节点信息。

现在集群就已经部署完毕

负载均衡设置

有了集群之后还要设置负载均衡,为了防止出现对单一节点造成高负载的情况。本次测试用例采用nginx为中间件，可根据自身需要进行选择。

拉取nginx镜像

1	`docker pull nginx`

创建映射目录及配置文件

1 2	`mkdir /home/rabbitmqnginx vim /home/rabbitmqnginx/rabbitmq.conf`

user  nginx;
worker_processes  2;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
