上一篇文章基于SpringBoot整合RocketMQ异步发送短信功能在项目启动的过程中报了 RocketMQ 连接错误。针对这个问题本文给予记录。
一、RocketMQ 连接报错处理
1.1 报错信息
Error starting ApplicationContext. To display the conditions report re-run your application with debug enabled.
2023-12-24 21:12:22.374 ERROR 26188 --- [ restartedMain] o.s.boot.SpringApplication : Application run failedjava.lang.RuntimeException: java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to [192.168.57.129:9876] failedat org.apache.rocketmq.spring.autoconfigure.ListenerContainerConfiguration.registerContainer(ListenerContainerConfiguration.java:123) ~[rocketmq-spring-boot-2.2.2.jar:2.2.2]at java.util.HashMap.forEach(HashMap.java:1289) ~[na:1.8.0_181]at org.apache.rocketmq.spring.autoconfigure.ListenerContainerConfiguration.afterSingletonsInstantiated(ListenerContainerConfiguration.java:79) ~[rocketmq-spring-boot-2.2.2.jar:2.2.2]at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:963) ~[spring-beans-5.3.6.jar:5.3.6]at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:918) ~[spring-context-5.3.6.jar:5.3.6]at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:583) ~[spring-context-5.3.6.jar:5.3.6]at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:144) ~[spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:782) [spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:774) [spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:439) [spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.run(SpringApplication.java:339) [spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.run(SpringApplication.java:1340) [spring-boot-2.4.5.jar:2.4.5]at org.springframework.boot.SpringApplication.run(SpringApplication.java:1329) [spring-boot-2.4.5.jar:2.4.5]at com.huang.quickstart.QuickStartApplication.main(QuickStartApplication.java:12) [classes/:na]at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_181]at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_181]at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_181]at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_181]at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49) [spring-boot-devtools-2.4.5.jar:2.4.5]简单的理解就是 RocketMQ 连接不上虚拟机地址 192.168.57.129:9876 信息。
1.2 修改 broker.conf 文件
进入 broker.conf 目录下
cd /mydata/rocketmq/rocketmq-4.9.1/confvim broker.conf加入两行(建议直接复制然后再修改为自己的IP)一定是大写IP。
namesrvAddr192.168.57.129:9876
brokerIP1192.168.57.129然后重启 nameserver 和 broker (一定要先启动 namesrv因为消息服务器是注册到命名服务器上的)。
nohup sh mqnamesrv再启动消息服务器同时指定刚刚修改过的 conf 文件不然还是会读取原本默认的阿里外网IP还是会报错。
nohup sh mqbroker -n 192.168.57.129:9876 -c ../conf/broker.conf备注 -n 指定的是注册到哪个消息服务器上 -c 指定的是刚刚修改的conf配置文件
查看日志信息 namesrv 和broker 启动成功
[rootlocalhost bin]# cat nohup.out
Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
The Name Server boot success. serializeTypeJSON
The broker[broker-a, 192.168.57.129:10911] boot success. serializeTypeJSON and name server is 192.168.57.129:9876重新启动 SpringBoot 项目发现还是报错
1.3 Linux 开放端口
排查了一下原因发现可能是 Linux 中 RocketMQ 的 9876 端口没有开放的问题
1、开启防火墙
systemctl start firewalld2、开放指定端口
firewall-cmd --zonepublic --add-port9876/tcp --permanent备注 –zone 作用域 –add-port9876/tcp 添加端口格式为端口/通讯协议 –permanent 永久生效没有此参数重启后失效
3、重启防火墙
firewall-cmd --reload4、查看端口号 netstat -ntlp #查看当前所有tcp端口
netstat -ntulp |grep 9876 #查看所有9876端口使用情况
1.4 项目启动成功
1、开放端口以及重启防火墙
[rootlocalhost bin]# firewall-cmd --zonepublic --add-port9876/tcp --permanent
success
[rootlocalhost bin]# firewall-cmd --reload
success2、重启启动 SpringBoot 项目
