第一种（单机部署RabbitMq的集群）
步骤1 先创建对应的挂载目录和shell脚本
mkdir -p /tmp/rabbitmq1/lib
mkdir -p /tmp/rabbitmq2/lib
mkdir -p /tmp/rabbitmq3/lib
mkdir -p /tmp/rabbitmq1/log
mkdir -p /tmp/rabbitmq2/log
mkdir -p /tmp/rabbitmq3/log
节点1（主节点脚本） vi /tmp/rabbitmq1/rabbitmq-ram.sh
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
节点2（节点脚本） vi /tmp/rabbitmq2/ rabbitmq-disk
rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@rabbit_host1
rabbitmqctl start_app
节点3（节点脚本） vi /tmp/rabbitmq3/ rabbitmq-disk
rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@rabbit_host1
rabbitmqctl start_app
步骤 2 创建docker-compose.yml文件并执行（docker-compose up -d）
version: '3'
services:
rabbitmq1:
image: rabbitmq:management
container_name: rabbitmq1
hostname: rabbit_host1
ports:
- "5672:5672"
- "15672:15672"
volumes:
- /tmp/rabbitmq1/lib:/var/lib/rabbitmq
- /tmp/rabbitmq1/log:/var/log/rabbitmq
- /tmp/rabbitmq1/rabbitmq-ram.sh:/opt/rabbitmq/rabbitmq-ram.sh

- RABBITMQ_DEFAULT_PASS=1234
- RABBITMQ_ERLANG_COOKIE=CURIOAPPLICATION
- RABBITMQ_NODENAME:rabbitmq1

rabbitmq2:

- "5673:5672"
- "15673:15672"

- "rabbitmq1"
volumes:

- /tmp/rabbitmq2/log:/var/log/rabbitmq

restart: always
environment:
- RABBITMQ_DEFAULT_USER=admin
- RABBITMQ_DEFAULT_PASS=1234
- RABBITMQ_ERLANG_COOKIE=CURIOAPPLICATION
- RABBITMQ_NODENAME:rabbitmq2
- RABBITMQ_CLUSTERED=true
- RABBITMQ_CLUSTER_WITH=rabbit@rabbitmq1
- RABBITMQ_RAM_NODE=true
networks:
- rabbitmq
rabbitmq3:
image: rabbitmq:management
container_name: rabbitmq3
hostname: rabbit_host3
ports:
- "5674:5672"
- "15674:15672"
depends_on:
- "rabbitmq1"
volumes:
- /tmp/rabbitmq3/lib:/var/lib/rabbitmq
- /tmp/rabbitmq3/log:/var/log/rabbitmq
- /tmp/rabbitmq3/rabbitmq-disk.sh:/opt/rabbitmq/rabbitmq-disk.sh
restart: always
environment:
- RABBITMQ_DEFAULT_USER=admin
- RABBITMQ_DEFAULT_PASS=1234
- RABBITMQ_ERLANG_COOKIE=CURIOAPPLICATION
- RABBITMQ_NODENAME:rabbitmq3
- RABBITMQ_CLUSTERED=true
- RABBITMQ_CLUSTER_WITH=rabbit@rabbitmq1
- RABBITMQ_RAM_NODE=true
networks:
- rabbitmq
networks:
rabbitmq:
driver: bridge
3 分别进入3个节点的容器中，并分别执行（shell脚本）
sh /opt/rabbitmq/rabbitmq-ram.sh
sh /opt/rabbitmq/ rabbitmq-disk.sh
sh /opt/rabbitmq/ rabbitmq-disk.sh
#4 查看集群节点状态,配置启动了3个节点，1个磁盘节点和2个内存节点（随便在一个节点的容器中执行该命令）
rabbitmqctl cluster_status
#5 创建好集群好我们要给集群加一个虚拟机环境/dev 以免程序报错
6 我们不能直接关机，要输入docker-compose down把容器关了再关机否则容器造成集群失败
集群重启顺序
集群重启的顺序是固定的，并且是相反的
启动顺序：磁盘节点 => 内存节点
关闭顺序：内存节点 => 磁盘节点
最后关闭必须是磁盘节点，否则容易造成集群启动失败、数据丢失等异常情况
因为这里使用的是Docker-Compose所以我们让从节点都依赖于主节点，只有主节点启动后，从节点才会启动，关闭是自动先关闭的是从节点，注意我们一定不能直接关机，要输入docker-compose down把容器关了再关机否则容器造成集群失败
depends_on:
- "rabbitmq1"
集群失败后重建集群
如果要重建集群的话必须把rabbitmq lib目录中的/mnesi目录删除掉
第二种（多机部署RabbitMq的集群）
除了docker-compose.yml的内容与单机部署不同之外，其他步骤均相同
docker-compose.yml三个机器都要写
