创建Docker私有网络

docker network create rabbitmqnet
docker run -d --name=rabbitmq1 -p 5673:5672 -p 15673:15672 -e RABBITMQ_NODENAME=rabbitmq1 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'  -h rabbitmq1 --net=rabbitmqnet  rabbitmq:3.6.10-management

docker run -d --name=rabbitmq2 -p 5674:5672 -p 15674:15672 -e RABBITMQ_NODENAME=rabbitmq2 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'  -h rabbitmq2 --net=rabbitmqnet  rabbitmq:3.6.10-management

docker run -d --name=rabbitmq3 -p 5675:5672 -p 15675:15672 -e RABBITMQ_NODENAME=rabbitmq3 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'  -h rabbitmq3 --net=rabbitmqnet  rabbitmq:3.6.10-management


docker exec rabbitmq2 bash -c  "rabbitmqctl stop_app && 
rabbitmqctl reset && 
rabbitmqctl join_cluster  --ram rabbitmq1@rabbitmq1 && 
rabbitmqctl start_app"


docker exec rabbitmq3 bash -c "rabbitmqctl stop_app && 
rabbitmqctl reset && 
rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && 
rabbitmqctl start_app"

--ram 指定了节点类型，目前一个磁盘节点两个内存节点
