rocketmq采坑: 连接异常 sendDefaultImpl call timeout

前提:

想使用rocketmq消息队列来做分布式事务处理的demo实验,安装完rocketmq后,并且启动namesrver, broker也成功了,但是使用springboot + rocketmq去连接时出现异常

环境:

centos7(172.xxx.xxx.251),rocketmq4.5.1,

springboot运行异常:

分析:

连接超时,初步猜测

可能原因一:是端口之类的东西没开放,但是查看centos上网路防火墙也未开启,排除端口未开放问题;

可能原因二:broker已经启动成功,可能注册的ip有误

①查看管理页面的集群列表:http://172.xxx.xxx.251:8080/#/cluster,发现broker的地址是10.244.0.11,这个是服务器内网地址

本地使用telnet 10.244.0.1 10911 可以发现明显的无法连接,所以需要修改broker的ip地址

处理:

#进入rocketmq  config目录,添加自定义配置
cd /opt/rocketmq/config/
#编写配置文件,并写好配置
echo "brokerIP1=172.xxx.xxx.251【服务器IP】" > broker.properties
#启动 mqnamesrv 
nohup sh bin/mqnamesrv &

#注意:mrbroker 启动时通过 -c 加载自定义配置文件
nohup sh bin/mqbroker -n 172.xxx.xxx.251:9876 -c /opt/rocketmq/config/broker.properties &

 停止RocketMQ命令
./bin/mqshutdown broker
./bin/mqshutdown namesrv

重启broker后,再次连接rocketmq,程序已经能正常连接了;果然接触新东西还是会踩不少雷
