?? 集群部署方式一（ rabbitmqctl )

參考資料： Clustering Transcript with rabbitmqctl

1、創(chuàng)建 rabbitmq 持久化存儲路徑

# 【所有節(jié)點】
mkdir -p ~/rabbitmq/data

2、在 node1 上新建部署文件 ~/rabbitmq/stack.yml

version: '3.7'
services:
  rabbit1:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
      - RABBITMQ_DEFAULT_USER=anoyi
      - RABBITMQ_DEFAULT_PASS=Passw0rd
    hostname: rabbit1
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node1
  rabbit2:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
      - RABBITMQ_DEFAULT_USER=anoyi
      - RABBITMQ_DEFAULT_PASS=Passw0rd
    hostname: rabbit2
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node2
  rabbit3:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
      - RABBITMQ_DEFAULT_USER=anoyi
      - RABBITMQ_DEFAULT_PASS=Passw0rd
    hostname: rabbit3
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node3

networks:
  rabbit_network:
    driver: overlay
    attachable: true

3、啟動 rabbitmq 服務

# 【node1】部署 stack
docker stack deploy -c ~/rabbitmq/stack.yml rabbitmq

# 【node1】查看服務狀態(tài)
docker service ls

直到出現(xiàn)如下列表：

ID                  NAME                MODE                REPLICAS            IMAGE               PORTS
j72ifjskqug5        rabbitmq_rabbit1    replicated          1/1                 rabbitmq:3
ihs9ec74mtng        rabbitmq_rabbit2    replicated          1/1                 rabbitmq:3
sb996gg4jtl2        rabbitmq_rabbit3    replicated          1/1                 rabbitmq:3

4、構建 rabbitmq 集群

將 rabbit@rabbit2 和 rabbit@rabbit3 加入集群：

#【node2】rabbit@rabbit2 加入集群
docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl stop_app

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl reset

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl join_cluster rabbit@rabbit1

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl start_app


#【node3】rabbit@rabbit3 加入集群
docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl stop_app

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl reset

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl join_cluster rabbit@rabbit1

docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl start_app

5支子、查看集群狀態(tài)

# 【任意節(jié)點】
docker exec -it $(docker ps | grep "rabbit" | awk '{ print $1 }')  rabbitmqctl cluster_status

?? 集群部署方式二（ Config File Peer Discovery Backend )

參考資料： How to Configure Peer Discovery

1、創(chuàng)建 rabbitmq 持久化存儲路徑

# 【所有節(jié)點】
mkdir -p ~/rabbitmq/data

2达舒、在 node1 上創(chuàng)建 rabbitmq 配置文件 ~/rabbitmq/rabbitmq.conf

loopback_users.guest = false
listeners.tcp.default = 5672
hipe_compile = false
default_user = anoyi
default_pass = Passw0rd
cluster_formation.peer_discovery_backend = rabbit_peer_discovery_classic_config
cluster_formation.classic_config.nodes.1 = rabbit@rabbit1
cluster_formation.classic_config.nodes.2 = rabbit@rabbit2
cluster_formation.classic_config.nodes.3 = rabbit@rabbit3

3值朋、在 node1 上創(chuàng)建 docker config

docker config create rabbitmq-config ~/rabbitmq/rabbitmq.conf

4叹侄、在 node1 上新建部署文件 ~/rabbitmq/stack.yml

version: '3.7'
services:
  rabbit1:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    configs:
      - source: rabbitmq-config
        target: /etc/rabbitmq/rabbitmq.conf
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
    hostname: rabbit1
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node1
  rabbit2:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    configs:
      - source: rabbitmq-config
        target: /etc/rabbitmq/rabbitmq.conf
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
    hostname: rabbit2
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node2
  rabbit3:
    image: rabbitmq:3
    networks:
      - rabbit_network
    volumes:
      - ~/rabbitmq/data:/var/lib/rabbitmq
    configs:
      - source: rabbitmq-config
        target: /etc/rabbitmq/rabbitmq.conf
    environment:
      - RABBITMQ_ERLANG_COOKIE=anoyi_cluster_cookie
    hostname: rabbit3
    deploy:
      replicas: 1
      placement:
        constraints:
          - node.hostname==node3

networks:
  rabbit_network:
    driver: overlay
    attachable: true

configs:
  rabbitmq-config:
    external: true

5、啟動 rabbitmq 集群

# 【node1】部署集群
docker stack deploy -c ~/rabbitmq/stack.yml rabbitmq

?? 番外補充

1昨登、Spring Boot 應用連接 RabbitMQ 集群配置

spring.rabbitmq.addresses=node1:5672,node2:5672,node3:5672
spring.rabbitmq.username=anoyi
spring.rabbitmq.password=Passw0rd

注意趾代，容器需要暴露端口 5672 供外部訪問
