一、准备 1
二、安装RabbitMQ在rabbit1,rabbit2,rabbit3 1
三、RabbitMQ集群配置 1
1、关闭所有rabbitq服务 1
2、设置hosts解析,所有rabbit节点配置相同 2
3、保证3台rabbit服务的cookie相同,把一台复制到其他两台 2
4、启动rabbit服务 2
5、创建集群,节点rabbit1,rabbit2 以RAM模式加入到rabbit3 2
6、节点rabbit移除 2
四、负载均衡配置 3
1、安装nginx 3
2、配置nginx.conf 3
一、准备
系统
描述
4个Debian / Ubuntu linux系统
分别安装在四台不同的物理机上,位于同一局域网,hostname不能相同，假设hostname分别为rabbit1,rabbit2,rabbit3,nginx
参考官方文档：
http://www.rabbitmq.com/clustering.html
http://www.rabbitmq.com/ha.html
http://www.rabbitmq.com/man/rabbitmqctl.1.man.html
http://www.rabbitmq.com/production-checklist.html
二、安装RabbitMQ在rabbit1,rabbit2,rabbit3
参考http://www.rabbitmq.com/install-debian.html
遇到问题：
1.无法访问管理控制台http://server::15672/#/
原因：安装默认关闭后台管理，需要重启rabbitmq-plugins enable rabbitmq_management 参考：http://www.rabbitmq.com/management.html
2.无法用guest登陆
原因:基于安全考虑rabbitmq默认只能本地用guest访问，远程无法访问
解决办法：http://www.cnblogs.com/mingaixin/p/4134920.html
创建用户 赋予管理员角色(生产环境不建议开启后台)
三、RabbitMQ集群配置
1、关闭所有rabbitq服务
rabbit# rabbitmqctl stop
2、设置hosts解析,所有rabbit节点配置相同
rabbit# vi /etc/hosts
192.168.70.207 rabbit1
192.168.70.208 rabbit2
192.168.70.209 rabbit3
3、保证3台rabbit服务的cookie相同,把一台复制到其他两台
rabbit# chmod 777 /var/lib/rabbitmq/.erlang.cookie
rabbit# vi /var/lib/rabbitmq/.erlang.cookie
rabbit# chmod 400 /var/lib/rabbitmq/.erlang.cookie
4、启动rabbit服务
rabbit1$ rabbitmq-server -detached
rabbit2$ rabbitmq-server -detached
rabbit3$ rabbitmq-server -detached
5、创建集群,节点rabbit1,rabbit2 以RAM模式加入到rabbit3
rabbit1$ rabbitmqctl stop_app
rabbit1$ rabbitmqctl join_cluster --ram __rabbit@rabbit__3
rabbit1$ rabbitmqctl start_app
rabbit2$ rabbitmqctl stop_app
rabbit2$ rabbitmqctl join_cluster --ram __rabbit@rabbit__3
rabbit2$ rabbitmqctl start_app
6、节点rabbit移除
rabbit1$ rabbitmqctl stop_app
rabbit1$ rabbitmqctl reset
rabbit1$ rabbitmqctl start_app
7、高可用策略配置,配置任何一个节点
rabbitmqctl set_policy ha-all-queue "^" '{"ha-mode":"all","ha-sync-mode":"automatic"}'
四、负载均衡配置
1、安装nginx
参考http://nginx.org/en/linux\_packages.html
2、配置nginx.conf
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

worker_connections 1024;
}
