赋予权限
chmod -R 777 /etc/rc.d/init.d/rabbitmq
添加开机启动服务
chkconfig --add rabbitmq
chkconfig rabbitmq on
启动rabbitmq服务
service rabbitmq start
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
开启rabbitmq web监控
rabbitmq-plugins enable rabbitmq_management
查看集群的状态
rabbitmqctl status
创建账号
rabbitmqctl add_user admin admin123
赋予其administrator
rabbitmqctl set_user_tags admin administrator
创建和赋角色完成后查看并确认
rabbitmqctl list_users
访问任意管理端界面查看http://ip:15672 可查看
192.168.31.2 192.168.31.3 192.168.31.4 配置相同的cookie,如果不相同的话，无法搭建集群.
echo PSNXAHYXQRPBKUVNYQCU > /root/.erlang.cookie
在192.168.31.3和192.168.31.4执行命令，加入到集群,其中--ram代表是内存节点，如果希望是磁盘节点则不用加--ram，在rabbitmq集群中，至少需要一个磁盘节点
rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@node1
rabbitmqctl start_app
查看集群的状态
rabbitmqctl cluster_status
设置成镜像队列 //意思表示以ha.开头的queue都会复制到各个节点 ["^"匹配所有]
rabbitmqctl set_policy ha-all "^ha\." '{"ha-mode":"all"}'
