rocketMQ 踩坑解决No route info of this topic和rocketmq:connect to 172.17.42.1:10911 failed

命令所在位置 /root/rocketmq-all-4.3.1/distribution/target/apache-rocketmq/bin

查看所有的topic集合

2. ./mqadmin topicList -n localhost:9876（首选）

创建topic

sh mqadmin updateTopic -n XXX:9876 -b XXX:10911 -t ESOrderListTopic

启动mqnamesrv

nohup sh mqnamesrv & ：属于后台启动

sh mqnamesrv ：属于终端启动，直接输出日志信息，按 ctrl+c 可直接关闭退出

# 查看启动日志能看到：The Name Server boot success字样则成功
$ tail -f ~/logs/rocketmqlogs/namesrv.log
先关闭namesrv服务：sh bin/mqshutdown namesrv

启动broker

nohup sh bin/mqbroker -n localhost:9876 & ：属于后台启动
建议 nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true &
 tail -f ~/logs/rocketmqlogs/broker.log查看日志或是cat nohup.out
关闭broker服务 ：sh bin/mqshutdown broker

启动broker报错

tail -f ~/logs/rocketmqlogs/broker.log

解决：注意启动命令路径对不对。

报错
还是启动命令不对

报错 No route info of this topic XXX 异常

一般来讲是因为rocket中没有XXX这个topic,我怕们可以手动在rocketmq自己添加一个。

    ```
    rocketmq命令都是在/root/rocketmq-all-4.3.1/distribution/target/apache-rocketmq/bin路径下
    sh mqadmin updateTopic -n XXX:9876 -b XXX:10911 -t ESOrderListTopic
    ```

RemotingConnectException: connect to <172.17.0.1:10911> failed

这个错误看代码是发送消息后出的问题，说明和代码没有关系

原因是：broker部署在虚拟机，并且虚拟双网卡，client无法正常连接服务端

解决： 在config/broker.conf配置文件中添加：

brokerIP1=服务器地址
namesrvAddr =服务器地址:9876

指定为本机的IP
然后重启rocketmq就可以了。
