前言
本小节我们学习一下使用Docker部署RabbitMQ集群。
RabbitMQ Docker Hub
目录参考
[root@iZ2ze8sm5upgi8z1dcazqeZ rabbitmq]# pwd

拉取rabbitmq镜像
docker pull rabbitmq:3.8-rc-management
若不使用Rabbitmq的management功能，可以拉取镜像：rabbitmq:3.8-rc
创建Rabbitmq共享网络
docker network create rabbitmqnet
[root@iZ2ze8sm5upgi8z1dcazqeZ data]# docker network ls

创建节点(三个节点)
注意这里使用相同的 RABBITMQ_ERLANG_COOKIE 值
```
#RabibitMQ Node1
docker run -d \
--name=rabbitmq1 \
-p 5672:5672 \
-p 15672:15672 \
-v /workspace/rabbitmq/data/rabbitmq1:/var/lib/rabbitmq:z \
-e RABBITMQ_DEFAULT_USER=Dustyone \
-e RABBITMQ_DEFAULT_PASS=bai5331359 \
-e RABBITMQ_NODENAME=rabbitmq1 \
-e RABBITMQ_ERLANG_COOKIE='Dustyone-Murex-cluster-cookie' \
-h rabbitmq1 \
--net=rabbitmqnet \
rabbitmq:3.8-rc-management
#RabibitMQ Node2
docker run -d \
--name=rabbitmq2 \
-p 5673:5672 \

```

组建rabbitmq集群
登陆Rabbitmq的后两个节点，执行命令加入第一个Rabbitmq节点集群
### Disk Node
# docker exec rabbitmq2 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"
### Ram Node
# docker exec rabbitmq3 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"
登录：http://你的公网IP:15672 ，使用
rabbitmq1-Dustyone/bai5331359登录,登录其他节点，访问相应的端口并使用相应的用户名/密码登录即可
退出集群
# docker exec rabbitmq3 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl start_app"
拉取haproxy镜像
docker pull haproxy
创建目录
/workspace/rabbitmq/haproxy-etc,并在该路径下创建haprox.cfg配置文件
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]# pwd
/workspace/rabbitmq/haproxy-etc
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]# tree
.
└── haproxy.cfg
0 directories, 1 file
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]#
haproxy.cfg配置信息如下：
#Simple configuration for an HTTP proxy listening on port 80 on all
# interfaces and forwarding requests to a single backend "servers" with a
# single server "server1" listening on 127.0.0.1:8000

server rabbit1 rabbitmq1:15672
server rabbit2 rabbitmq2:15672
server rabbit3 rabbitmq3:15672
拉取haproxy镜像
docker pull haproxy
启动haproxy
docker run -d \
--name rabbitmq-haproxy \
-p 8002:8002 -p 5677:5677 -p 8001:8001 \
--net=rabbitmqnet \
-v /workspace/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro \
haproxy:latest
启动haproxy后，可以通过haproxy来访问rabbitmq集群：http://你的公网IP:8001
获取haproxy的状态：http://你的公网IP:8002/haproxy?stats

将rabbitmq2和rabbitmq3两个节点加入rabbitmq1节点以形成集群。
### Disk Node
docker exec rabbitmq2 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"
### Ram Node
# docker exec rabbitmq3 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"
[root@iZ2ze8sm5upgi8z1dcazqeZ config]# docker exec rabbitmq2 bash -c \

[root@iZ2ze8sm5upgi8z1dcazqeZ config]# docker exec rabbitmq3 bash -c \
> "rabbitmqctl stop_app && \
> rabbitmqctl reset && \
> rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \

[root@iZ2ze8sm5upgi8z1dcazqeZ config]#
访问http://你的公网IP:8002
如此便完成了使用docker-compose部署Rabbitmq集群
启动停止Rabbitmq-Cluster建议使用如下Command
docker-compose up -d
docker-compose stop
此类方法部署RabbitMQ集群有很多细节，便不一一说明了，挑几个重用的说一下
所有的节点最好共享一个网络块
执行docker-compose.yml之前要创建好所有的配置文件
