RABBITMQ4.0集群部署

机器准备

集群机器数量最小为两台，为了防止脑裂问题最好大于等于三台且为奇数

网络环境

设置主机名，三台机器分别设置为rabbitmq1、rabbitmq2、rabbitmq3

# host1
sudo hostnamectl set-hostname rabbitmq1

# host2
sudo hostnamectl set-hostname rabbitmq2

# host3
sudo hostnamectl set-hostname rabbitmq3

设置主机名-IP映射

查询每台机器的ip地址，可用以下命令查询

ifconfig

查询后在所有机器的/etc/hosts文件中增加映射

192.168.1.1 rabbitmq1
192.168.1.2 rabbitmq2
192.168.1.3 rabbitmq3

防火墙

开放防火墙端口
4369（Erlang端口映射）、25672（节点通信）、5672（AMQP）、15672（管理插件）

集群部署

cookie迁移

将rabbitmq1的cookie文件复制到其他机器

sudo scp /var/lib/rabbitmq/.erlang.cookie /var/lib/rabbitmq/.erlang.cookie

rabbitmq2和rabbitmq3设置cookie文件归属

sudo chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
sudo chmod 600 /var/lib/rabbitmq/.erlang.cookie

rabbitmq2、rabbitmq3加入rabbitmq集群

# 重启rabbitmq服务让cookie生效
sudo systemctl restart rabbitmq-server.service
# 关闭当前应用
sudo rabbitmqctl stop_app
# 加入并启动集群应用
sudo rabbitmqctl join_cluster rabbit@rabbitmq1
sudo rabbitmqctl start_app

查看集群状态并设置开机启动

# 查看集群信息，节点包括所有机器
sudo rabbitmqctl cluster_status
# 所有机器执行开机自启
sudo systemctl enable rabbitmq-server.service
