本次使用单机docker集群部署,docker安装详情其他文档
集群部署
拉取镜像
1
| docker pull rabbitmq:3.7-management
|
创建映射卷
1 2 3 4
| docker volume create rabbitmq01 docker volume create rabbitmq02 docker volume create rabbitmq03 docker volume list
|
启动容器
节点1
1
| docker run -d --hostname rabbitmq01 --name rabbitmqCluster01 -v rabbitmq01:/var/lib/rabbitmq -p 15673:15672 -p 5673:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie' rabbitmq:3.7-management
|
节点2
1
| docker run -d --hostname rabbitmq02 --name rabbitmqCluster02 -v rabbitmq02:/var/lib/rabbitmq -p 15674:15672 -p 5674:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie' --link rabbitmqCluster01:rabbitmq01 rabbitmq:3.7-management
|
节点3
1
| docker run -d --hostname rabbitmq03 --name rabbitmqCluster03 -v rabbitmq03:/var/lib/rabbitmq -p 15675:15672 -p 5675:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitmqCookie' --link rabbitmqCluster01:rabbitmq01 --link rabbitmqCluster02:rabbitmq02 rabbitmq:3.7-management
|
查询容器启动情况 up为启动成功
注: –hostname 设置容器的主机名RABBITMQ_ERLANG_COOKIE 节点认证作用,部署集成时 需要同步该值
启动容器成功后,可以访问

账号/密码:guest / guest
登陆后,查看overview Tab页,可看到节点信息。
容器节点加入集群
容器1
1
| docker exec -it rabbitmqCluster01 bash
|
1 2 3 4
| rabbitmqctl stop_app rabbitmqctl reset rabbitmqctl start_app exit
|
容器2
1
| docker exec -it rabbitmqCluster02 bash
|
1 2 3 4 5
| rabbitmqctl stop_app rabbitmqctl reset rabbitmqctl join_cluster --ram rabbit@rabbitmq01 rabbitmqctl start_app exit
|
容器3
1
| docker exec -it rabbitmqCluster03 bash
|
1 2 3 4 5
| rabbitmqctl stop_app rabbitmqctl reset rabbitmqctl join_cluster --ram rabbit@rabbitmq01 rabbitmqctl start_app exit
|
执行上述操作,这时候 再查看 http://192.168.117.151:15673/#/的overview面板中的Nodes信息,可查看到节点信息。
现在集群就已经部署完毕
负载均衡设置
有了集群之后 还要设置负载均衡,为了防止出现对单一节点造成高负载的情况。 本次测试用例 采用nginx为中间件,可根据自身需要进行选择。
拉取nginx镜像
创建映射目录及配置文件

| mkdir /home/rabbitmqnginx vim /home/rabbitmqnginx/rabbitmq.conf

server { listen 5672 proxy_pass rabbitTcp } }
|
创建nginx容器
1
| docker run -d --name nginxRabbitmq -v /home/rabbitmqnginx/rabbitmq.conf:/etc/nginx/nginx.conf --privileged --net=host nginx
|
然后可以通过 192.168.117.151:15672 进行管理 以及通过 5672 端口 进行rabbitmq通信。
