Docker搭建RabbitMQ（单机版）

采用bijukunjummen提供的镜像。

 

1	$ git clone https://github.com/bijukunjummen/docker-rabbitmq-cluster.git

启动集群，别忘记安装docker daemon和docker-compose

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

$ cd docker-rabbitmq-cluster/cluster $ docker-compose up -d Pulling rabbit1 (bijukunjummen/rabbitmq-server:latest)... latest: Pulling from bijukunjummen/rabbitmq-server 8d30e94188e7: Pull complete 4dcc5ee4075c: Pull complete 9554738b08fc: Pull complete efdc65d45fa8: Pull complete 8511de892111: Pull complete 370e6c0ab215: Pull complete 940500e823fe: Pull complete b6134aab1a2a: Pull complete b870c2ab7ca0: Pull complete 56ed51d99ae0: Pull complete adec15369e34: Pull complete 1f44e442c116: Pull complete 0dcd19841c9f: Pull complete 24b8906417b0: Pull complete Digest: sha256:a6bbb268de87d09d538152450b77835a27693039ab079785a7b72f595bef18a6 Status: Downloaded newer image for bijukunjummen/rabbitmq-server:latest Creating cluster_rabbit1_1 Creating cluster_rabbit2_1 Creating cluster_rabbit3_1

默认启动了三个节点

查看容器

访问
http://192.168.99.100:15672，弹出登陆界面。输入guest/guest

然后就可以添加用户了。

Docker搭建RabbitMQ集群（多机版）

上面我们使用Docker搭建出了一个RabbitMQ单机集群，这种模式只能用来测试玩玩，无法再生产环境中使用。在生产环境中，需要把3个节点的集群分布到各个主机上面去。这个时候docker-compose就需要做调整了，主要是对外端口和link方式，首先我们说一下RabbitMQ开启后的对外端口。

SELinux和类似机制或许会通过绑定端口的方式阻止RabbitMQ。当这种情况发生时，RabbitMQ会启动失败。请确认以下的端口是可以被打开的：

4369 (epmd)

25672 (Erlang distribution)

5672, 5671 (启用了或者未启用TLS的AMQP 0-9-1)

15672 (如果管理插件被启用)

61613, 61614 (如果STOMP被启用)

1883, 8883 (如果MQTT被启用)

说完端口，下面提供一个三节点的docker-compose文件。

rabbit1（10.106.136.7）

 

1 2 3 4 5 6 7 8 9 10 11 12

rabbit1:   image: bijukunjummen/rabbitmq-server   hostname: rabbit1   ports:     - "5672:5672"     - "4369:4369"     - "1883:1883"     - "15672:15672"     - "25672:25672"   environment:     - RABBITMQ_DEFAULT_USER=myuser     - RABBITMQ_DEFAULT_PASS=mypass

rabbit2（10.106.136.8）

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

rabbit2:   image: bijukunjummen/rabbitmq-server   hostname: rabbit2   extra_hosts:     - "rabbit1:10.106.136.7"   environment:    - CLUSTERED=true    - CLUSTER_WITH=rabbit1    - RAM_NODE=true   ports:       - "5672:5672"       - "4369:4369"       - "1883:1883"       - "15672:15672"       - "25672:25672"

rabbit3（10.106.136.9）

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

rabbit3:   image: bijukunjummen/rabbitmq-server   hostname: rabbit3   extra_hosts:     - "rabbit1:10.106.136.7"     - "rabbit2:10.106.136.8"   environment:    - CLUSTERED=true    - CLUSTER_WITH=rabbit1    - RAM_NODE=true   ports:         - "5672:5672"         - "4369:4369"         - "1883:1883"         - "15672:15672"         - "25672:25672"

然后依序在三个节点上分别开启rabbitmq，然后随意找个节点打开IP:25672，输入guest用户名和guest密码就可以查看集群了。
