遇到问题：
4 v7 e# ~* z6 s7 jrabbitmq很特别，在保证端口不被冲突的情况下，需要配置rabbitmq-env，这样的话rabbitmq的端口才会写到本机的端口上，才不会和haproxy启动的端口发生冲突。
0 q6 O" W, Q" O. X. M" l$ ~
rabbitmq-env这个文件呢，配置RABBITMQ_NODE_IP_ADDRESS="controller3
是错的，千万要记住哦，
: t' j# F/ A) R% K  }4 _% D% L这个地方必须写成IP地址：
例如：
+ T2 N8 q" \  E8 R cat /etc/rabbitmq/rabbitmq-env.conf
4 m' M: f3 @4 x8 L% Z6 h- r  v RABBITMQ_NODE_IP_ADDRESS="192.168.26.7"

- F/ p' L9 ^1 W3 Y, }: s- R启动就会正常了。

解决办法：
检查修改rabbitmq-env.conf文件，写成ip地址就可以了。hosts域名解析不可用。
