安装docker

---

• 本次借鉴同事的安装文件, install.sh 离线方式部署docker , 不适用rpm包 避免无网络情况下依赖关系复杂.

---

导入rabbitmq的镜像文件.

---

• 导入rabbitmq:manangement 的容器镜像. 避免每次离线安装rabbitmq 缺少依赖关系. 比较繁琐.

---

启动容器镜像

---

• 修改或者使用已有的机器名称.

修改 /etc/hosts
将两台机器可以设置为 互相ping机器名可以通信. 

• 创建目录,持久化rabbitmq的消息队列文件目录

mkdir -p /data/rabbitmq/data

• 启动镜像, 在互为容器镜像的两个虚拟机上面都启动镜像, 注意我这边为了简单, 设置为机器名一样的情况
• 使用 --net=host 暴露本地端口. 设置密码, 设置容器名字,以及node名字,这里设置与机器名保持一致.

docker run -d --name=ZJ01 --net=host -e RABBITMQ_NODENAME=ZJ01 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' -v /data/rabbitmq/data:/var/lib/rabbitmq  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=Test1127 -h ZJ01 rabbitmq:management

docker run -d --name=ZJ02 --net=host -e RABBITMQ_NODENAME=ZJ02 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' -v /data/rabbitmq/data:/var/lib/rabbitmq  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=Test1127 -h ZJ02 rabbitmq:management

• 进入 ZJ02 节点执行 join cluster的操作

docker exec -it ZJ02 bash
rabbitmqctl stop_app
# 加入集群
rabbitmqctl join_cluster ZJ01@ZJ01
# 重启服务
rabbitmqctl start_app
# 设置为镜像模式
rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
# 查看集群状态
rabbitmqctl cluster_status

一般查看集群状态效果为:

root@ZJ02:/# rabbitmqctl cluster_status
Cluster status of node ZJ02@ZJ02 ...
