8 P; J, z' Y9 i3 b9 J! e, f' G遇到问题：
rabbitmq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。
$ E2 s7 d: _0 `4 F* ^2 E4 P% ?
5 `* b) C) M* D! w  [( Wrabbitmq-env这个文件呢，配置RABBITMQ_NODE_IP_ADDRESS="controller3
& |' b/ b5 I1 ~是错的，千万要记住哦，
. p8 W0 z: z8 Q' ~) z这个地方必须写成IP地址：
例如：
4 r5 |3 f1 W9 y: b1 N- L cat /etc/rabbitmq/rabbitmq-env.conf
, z, k# n7 m/ ~  S" E0 [ RABBITMQ_NODE_IP_ADDRESS="192.168.26.7"

启动就会正常了。

解决办法：
% P, s: g; Q, v% n( |) B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。
