docker安装rocketmq 后，broker无法访问解决办法

前提：使用docker安装了rocketmq,docker安装请查看上一篇 docker快速部署rocketmq

1、测试发送消息，错误信息如下：

Caused by: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <172.18.0.4:10911> failed

2、错误原因：连接超时，172.18.0.4是内网ip。

3、解决方案：进入容器，修改配置：

       docker exec -it --user root rmqbroker bash

        cd ../conf

        vi broker.conf

     配置信息如下：

 

 4.重启broker，修改生效，即可以正常访问。
