前情提要
真实部署环境是机房环境，不能携带手机，所以需要进行提前演练，我使用的docker镜像的方式进行构建。docker的环境搭建详见：两台服务器搭建三个节点-CSDN博客
rabbitmq的安装
加载指定的依赖文件
删除容器，重新构建（保证纯净）
docker stop demo-container
docker rm demo-container
#使用镜像启动容器
docker run -itd --name demo-container --privileged --volume /sys/fs/cgroup:/sys/fs/cgroup:ro kylin-with-systemd:v10-sp3 /usr/lib/systemd/systemd
copy文件到容器
docker cp rabitmq.zip demo-container:/home
进入容器
docker exec -it demo-container bash
cd /home
unzip rabitmq.zip
cd rabitmq
rpm包的安装
安装 Erlang 和 RabbitMQ 的所有依赖（强制安装）
rpm -ivh --force --nodeps *.rpm
查看是否成功安装rabbitmq服务
systemctl list-unit-files --type=service |grep rabbitmq
查看rabbitmq的启动脚本位置。(我的是：/usr/lib/systemd/system/rabbitmq-server.service)
find / -name "rabbitmq-server.service"
配置文件的配置
创建工作目录
ll /var/lib |grep rabbit
cp -rp /var/lib/rabbitmq /var/lib/rabbitmq3
cp -rp /var/lib/rabbitmq /var/lib/rabbitmq2
cp -rp /var/lib/rabbitmq /var/lib/rabbitmq1
编辑启动脚本文件
不明原因导致的使用配置文件启动失败。
nodeName整个集群内不能重复，@后面的域名必须能通过ping可达。
vim /usr/lib/systemd/system/rabbitmq-server-3.service

Install
WantedBy=multi-user.target
启动命令
systemctl daemon-reload
systemctl stop rabbitmq-server-3.service
systemctl start rabbitmq-server-3.service
systemctl status rabbitmq-server-3.service
systemctl start rabbitmq-server-3.service
systemctl start rabbitmq-server-2.service
systemctl start rabbitmq-server-1.service
查看节点运行情况：
rabbitmqctl rabbit03@localhostcluster_status
集群组建
同步erlang的cookie文件
#组建集群：RabbitMQ 集群依赖 Erlang 集群，而 Erlang 集群通过 Cookie 进行通信认证，所以要保证所有机器的 .erlang.cookie 内容一致，且为只读权限
systemctl stop rabbitmq-server-3.service
systemctl stop rabbitmq-server-2.service
systemctl stop rabbitmq-server-1.service
chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie
cp rabbitmq/.erlang.cookie rabbitmq2/.erlang.cookie
cp rabbitmq/.erlang.cookie rabbitmq1/.erlang.cookie
cp rabbitmq/.erlang.cookie rabbitmq3/.erlang.cookie
systemctl start rabbitmq-server-1.service
systemctl start rabbitmq-server-2.service
systemctl start rabbitmq-server-3.service
其他节点加入主节点
节点02 加入03主节点（因为node被重命名，必须加-n 启动脚本的nodeName）
停止app
rabbitmqctl -n rabbit02@localhost stop_app
重置
rabbitmqctl -n rabbit02@localhost reset
加入节点
rabbitmqctl -n rabbit02@localhost join_cluster rabbit03@localhost
启动节点
rabbitmqctl -n rabbit02@localhost start_app
节点01 加入03主节点
rabbitmqctl -n rabbit01@localhost stop_app
rabbitmqctl -n rabbit01@localhost reset
rabbitmqctl -n rabbit01@localhost join_cluster rabbit03@localhost
rabbitmqctl -n rabbit01@localhost start_app
验证集群启动状态
rabbitmqctl -n rabbit@localhost cluster_status
