Rabbitmq主备模式+haproxy

Rabbitmq主备模式+haproxy

主机准备

172.19.220.172   xm-test_02-172
172.19.220.140   xm-test-172
/etc/hosts信息

172.19.220.172  xm-test_02-172
172.19.220.140  xm-test-172
hostname信息

xm-test_02-172.19.220.172-sh
xm-test-172.19.220.140-sh

一、首先安装rabbitmq-server

1、软件安装

wget https://github.com/rabbitmq/erlang-rpm/releases/download/v21.2.2/erlang-21.2.2-1.el6.x86_64.rpm
rpm -Uvh erlang-21.2.2-1.el6.x86_64.rpm
yum install -y socat
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
rpm -ivh https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.9/rabbitmq-server-3.7.9-1.el7.noarch.rpm
systemctl enable rabbitmq-server
systemctl start rabbitmq-server

2、账户设置

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl list_users
rabbitmqctl change_password admin xxxxxxxxxx
rabbitmqctl list_users
rabbitmqctl set_user_tags admin administrator

3、主备设置

设置
xm-test_02-172.19.220.172-sh为主节点

拷贝主节点
/var/lib/rabbitmq/.erlang.cookie 的文件内容到从节点替代从节点对应文件的内容/var/lib/rabbitmq/.erlang.cookie

在从节点上 *** 作如下信息

#rabbitmqctl stop_app
#rabbitmqctl reset
#rabbitmqctl join_cluster rabbit@xm-test_02-172
Clustering node rabbit@xm-test-172 with rabbit@xm-test_02-172[[email protected] rabbitmq]$rabbitmqctl start_appStarting node rabbit@xm-test-172 ...completed with 3 plugins.
#rabbitmqctl start_app

这就设置成功，查看cluser信息

在从节点上查看

#rabbitmqctl cluster_status
Cluster status of node rabbit@xm-test-172 ...[{nodes,[{disc,['rabbit@xm-test-172','rabbit@xm-test_02-172']}]},{running_nodes,['rabbit@xm-test_02-172','rabbit@xm-test-172']},{cluster_name,<<"rabbit@xm-test_02-172">>},{partitions,[]},{alarms,[{'rabbit@xm-test_02-172',[]},{'rabbit@xm-test-172',[]}]}]
在主节点上查看

#rabbitmqctl cluster_status
Cluster status of node rabbit@xm-test_02-172 ...[{nodes,[{disc,['rabbit@xm-test-172','rabbit@xm-test_02-172']}]},{running_nodes,['rabbit@xm-test-172','rabbit@xm-test_02-172']},{cluster_name,<<"rabbit@xm-test_02-172">>},{partitions,[]},{alarms,[{'rabbit@xm-test-172',[]},{'rabbit@xm-test_02-172',[]}]}]

这样控制台上就线上两台主机了

 

剔除节点的 *** 作

在需要被剔除的节点上 *** 作

rabbitmq-server -detached
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app


添加集群节点

rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@xm-test_02-172    //内存模式，不加ram是磁盘模式
rabbitmqctl start_app
授权

rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'


haproxy安装配置

yum -y install haproxy配置
haproxy.cfg 内容如下
