Docker安装RabbitMQ集群

一、安装单机版

1、更新yum源安装 vim、net-tools等工具

 yum update -y
 yum install vim -y
 yum install net-tools -y

2、安装单机版

#创建挂载路径
mkdir /data/rabbitmq -p


#拉取镜像
docker pull rabbitmq:3.9-management


#创建容器并启动
docker run  -d -it  --name rabbitmq \
-v /data/rabbitmq:/var/lib/rabbitmq \
-p 5672:5672 -p 15672:15672 rabbitmq:3.9-management

如果拉取镜像报错

解决方法修改dns解析

vim /etc/resolv.conf

#修改内容如下
#nameserver 192.168.139.2
nameserver 114.114.114.114
nameserver 8.8.8.8

二、安装集群

1、安装容器

#创建挂载目录
mkdir /data/rabbitmq1 -p
mkdir /data/rabbitmq2 -p
mkdir /data/rabbitmq3 -p

#节点1
docker run -d --hostname rabbit1 --name rabbitmq1 \
-p 15672:15672 -p 5672:5672 \
-v /data/rabbitmq1:/var/lib/rabbitmq \
-e RABBITMQ_ERLANG_COOKIE='rabbitmq_cookie' rabbitmq:3.9-management



#节点2
docker run -d --hostname rabbit2 --name rabbitmq2 \
-p 5673:5672 --link rabbitmq1:rabbit1 \
-v /data/rabbitmq2:/var/lib/rabbitmq \
-e RABBITMQ_ERLANG_COOKIE='rabbitmq_cookie' rabbitmq:3.9-management



#节点3
docker run -d --hostname rabbit3 --name rabbitmq3 \
-p 5674:5672 --link rabbitmq1:rabbit1 --link rabbitmq2:rabbit2 \
-v /data/rabbitmq3:/var/lib/rabbitmq \
-e RABBITMQ_ERLANG_COOKIE='rabbitmq_cookie' rabbitmq:3.9-management

2、添加节点

3、此时登录rabbitmq可视化平台

192.168.139.191:15672 默认账号密码是guest

4、配置镜像集群模式

name：随便取，策略名称
Pattern：^ 匹配符，只有一个^代表匹配所有
Definition：ha-mode=all 为匹配类型，分为3种模式：all（表示所有的queue）。
