**编写rabbitmq.yml文件**

version: "3.7"
    networks:
      xxl:
        external: true		//外部创建覆盖网络xxl
        name: xxl
        driver: overlay
        ipam:
          config:
            - subnet: 172.22.0.0/16
    volumes:
      rabbitmq-cookie:
        external: true		//为避免windows权限问题和重启重置，使用docker命名卷
    services:
      rabbit1:
        image: xxl-rabbitmq		//自定义的镜像
        networks:
          - xxl
        volumes:
          - rabbitmq-cookie:/var/lib/rabbitmq
        environment:
          - RABBITMQ_ERLANG_COOKIE="xxl_civic_xxl"
        hostname: rabbit1
        deploy:
          replicas: 1
      rabbit2:
        image: xxl-rabbitmq
        networks:
          - xxl
        volumes:
          - rabbitmq-cookie:/var/lib/rabbitmq
        environment:
          - RABBITMQ_ERLANG_COOKIE="xxl_civic_xxl"
        hostname: rabbit2
        deploy:
          replicas: 1
      rabbit3:
        image: xxl-rabbitmq
        networks:
          - xxl
        volumes:
          - rabbitmq-cookie:/var/lib/rabbitmq
        environment:
          - RABBITMQ_ERLANG_COOKIE="xxl_civic_xxl"
        hostname: rabbit3
        deploy:
          replicas: 1

**swarm模式启动集群**

//启动服务栈
    docker stack deploy -c rabbitmq.yml rabbtimq
    //移除服务栈
    docker stack rm rabbitmq

**使用[portainer][]图形界面配置rabbitmq集群**

//进入rabbit1容器，作为集群基准
    rabbitmqctl stop_app
    rabbitmqctl reset
    rabbitmqctl start_app
    
    //进入rabbit2容器
    rabbitmqctl stop_app
    rabbitmqctl reset
    rabbitmqctl join_cluster rabbit@rabbit1
    rabbitmqctl start_app
    
    //进入rabbit3容器
    rabbitmqctl stop_app
    rabbitmqctl reset
    rabbitmqctl join_cluster rabbit@rabbit1
    rabbitmqctl start_app

**使用nginx作为代理暴露服务到宿主机**

*  nginx.yml

version: "3.7"
    networks:
      xxl:
        external: true
        name: xxl
        driver: overlay
        ipam:
          config:
            - subnet: 172.22.0.0/16
    services:
      gateway:
        image: nginx:latest
        networks:
          - xxl
        ports:
          - "15672:15672"
          - "5672:5672"
          - "1883:1883"
          - "15675:15675"
        volumes:
          - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
        deploy:
          replicas: 1
        depends_on:
          - rabbit1
          - rabbit2
          - rabbit3

*  nginx.conf

http {
    	upstream web {
    		server rabbit1:15672;
    		server rabbit2:15672;
    		server rabbit3:15672;
    	}
    
    	server {
    		listen 15672;
    		server_name localhost;
    
    		location / {
    			proxy_pass http://web;
    		}
    
    	}
    
    	upstream webmqtt {
    		server rabbit1:15675;
    		server rabbit2:15675;
    		server rabbit3:15675;
    	}
    
    
    	server {
    		listen 15675;
    		server_name localhost;
    
    		location / {
    			proxy_pass http://webmqtt;
    			proxy_http_version 1.1;
    			proxy_set_header Upgrade $http_upgrade;
    			proxy_set_header Connection "upgrade";
    		}
    	}
    }
    stream {
    
    	upstream mqtt {
    		server rabbit1:1883;
    		server rabbit2:1883;
    		server rabbit3:1883;
    	}
    
    	server {
    		listen 1883;
    		proxy_timeout 60s;
    		proxy_pass mqtt;
    	}
    
    	upstream amqp {
    		server rabbit1:5672;
    		server rabbit2:5672;
    		server rabbit3:5672;
    	}
    
    	server {
    		listen 5672;
    		proxy_timeout 60s;
    		proxy_pass amqp;
    	}
    }

*  启动nginx

//启动服务栈
    docker stack deploy -c nginx.yml gateway
    //移除服务栈
    docker stack rm gateway
