运行consumer后发现
com.alibaba.rocketmq.remoting.exception.RemotingConnectException: connect to <10.105.23.114:10911> failed
在nohup.out里发现 
The broker[localhost, 10.105.23.114:10911] boot success. and name server is 182.254.145.65:9876
哎,看来还是外网内网ip的问题

上次在安装Tair的时候就碰到过类似的问题 详见  Centos7安装Tair及配置测试

最后经过多方搜索,在官方的用户说明里看到下面的方法

经过我修改后的broker.p

ok!
这说明什么?说明第一手资料很重要
