Centos7的rabbitmq鏡像集羣

一、下載RabbitMQ

vim /etc/hosts
10.10.21.197 rabbit1
10.10.21.198 rabbit2

#分別命名
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

二、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

#兩臺
chmod 400 /var/lib/rabbitmq/.erlang.cookie

systemctl stop rabbitmq-server

rabbitmq-server -detached

# 在要加入集羣的節點操做
rabbitmqctl stop_app #中止應程序
rabbitmqctl reset #清空元數據
rabbitmqctl join_cluster rabbit@rabbit1 --ram　＃將rabbitmq-server1添加到集羣當中，併成爲內存節點，不加--ram默認是磁盤節點
rabbitmqctl start_app #不要忘記啓動應用程序

# 移除節點
# 軟刪除
# 若是想要把節點從集羣中移除，可以使用以下命令實現：
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
rabbitmqctl cluster_status

# 硬刪除
# 直接刪掉集羣中的某個節點

rabbitmqctl forget_cluster_node rabbit@Demo20

 

# 更改成鏡像模式
rabbitmqctl set_policy ha-all "#" '{"ha-mode":"all"}'

三、haproxy集羣設置
