Centos7的rabbitmq镜像集群

1、下载RabbitMQ

vim /etc/hosts
10.10.21.197 rabbit1
10.10.21.198 rabbit2

#分别命名
hostname rabbit1
hostname rabbit2

vim /etc/yum.repos.d/rabbitmq.repo
[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/
gpgcheck=0
repo_gpgcheck=0
enabled=1

[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/22/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

yum install rabbitmq-server

cp /usr/share/doc/rabbitmq-server-3.7.20/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config

systemctl start rabbitmq-server

2、配置rabbitMQ

rabbitmqctl add_user admin 123456
rabbitmqctl set_permissions admin ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator

rabbitmq-plugins enable rabbitmq_management
rabbitmq-plugins list

scp /var/lib/rabbitmq/.erlang.cookie 192.168.10.202:/var/lib/rabbitmq/.erlang.cookie

#两台
chmod 400 /var/lib/rabbitmq/.erlang.cookie

systemctl stop rabbitmq-server

rabbitmq-server -detached

# 在要加入集群的节点操作
rabbitmqctl stop_app #停止应程序
rabbitmqctl reset #清空元数据
rabbitmqctl join_cluster rabbit@rabbit1 --ram　＃将rabbitmq-server1添加到集群当中，并成为内存节点，不加--ram默认是磁盘节点
rabbitmqctl start_app #不要忘记启动应用程序

# 移除节点
# 软删除
# 如果想要把节点从集群中移除，可使用如下命令实现：
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
rabbitmqctl cluster_status

# 硬删除
# 直接删掉集群中的某个节点

rabbitmqctl forget_cluster_node rabbit@Demo20

# 更改为镜像模式
rabbitmqctl set_policy ha-all "#" '{"ha-mode":"all"}'

3、haproxy集群设置
