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。

' Q9 L9 H" l' l% U# r+ ^, {. l0 Brabbitmq-env这个文件呢，配置RABBITMQ_NODE_IP_ADDRESS="controller3
: l0 a  y/ X! z是错的，千万要记住哦，
这个地方必须写成IP地址：
例如：
8 C/ a$ Z  b- l+ ` cat /etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_NODE_IP_ADDRESS="192.168.26.7"

解决办法：
) d; L! [  X3 S- W3 N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。
