购买了3台阿里云ECS服务器,上面部署了RocketMQ,用来作为业务后台与平台之间的数据通讯中间件。
部署倒是异常顺利,不过在本地写程序,测试生产和消费数据的时候,出现了一些问题。
耗费了将近1天的时间,终于解决了,记录一下本次排查的经历。
Linux:CentOS8(阿里云ECS服务器)
RocketMQ:4.6.1
节点数:3个
节点1:broker-a(master)
节点2:broker-a(slave),broker-b(master)
节点3:broker-b(slave)
配置文件如下(IP地址省略了):

配置完成之后,尝试在客户端编写生产者代码,结果生产数据的时候报错。
org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to [xxxx] failed
把生产者和消费者的代码中增加setSendMessageWithVIPChannel(false)。
结果:依然报错,错误没有改变
在配置文件中增加brokerIP1=xx.xx.xx.xx的配置。
结果:依然报错,错误没有改变
网上说是防火墙的问题,服务器本身的防火墙很早就已经被关闭了。尝试去设置阿里云ECS服务器产品的端口。
一次性的把一个10900/10999的端口全部开放
结果:测试同步生产数据正常。
测试异步生产数据。调用RocketUtils中的sendAsync方法。结果报错:
[------]onException. org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to [101.132.242.90:9876, 47.116.50.192:9876] failed [------]onException.

原因是使用异步生产数据的时候,我的程序里调用了shutdown方法,
导致后续的异步线程无法正常执行。注释掉shutdown处理之后,异步生产正常。
如果出现connect to [xxxx] failed的问题,不外乎尝试以下几种办法:
1、程序中:生产者或者消费者:setSendMessageWithVIPChannel(false)
2、配置文件:如果是阿里云ECS服务器,以下两个配置使用外网地址:
brokerIP1=xx.xx.xx.01
namesrvAddr=xx.xx.xx.01:9876;xx.xx.xx.02:9876
3、防火墙:关闭服务器本身的防火墙。
4、安全组:阿里云服务器本身的网络安全组中需要开通端口。
生产者已经没有问题了,但是消费者一直消费不到数据。程序不报任何错误,就是消费不到数据。
在网上找了一些到有的博客,其中这篇给了我一些方向,
http://www.jiangxinlingdu.com/rocketmq/2019/08/06/noconsumer.html
初步怀疑是消费者的偏移量有问题。
我这个环境由于是新搭环境,目前还不是生产环境,所以我直接采用的方式是:
1、停止rocketmq集群
2、删除所有rocketmq的文件
3、重启集群
4、重新创建topic
一套暴利连招之后,消费者果然可以消费到数据了。
索然没有真正的找到问题的原因,不过基本上可以确定是rocketmq的元数据出现了问题,
这个问题的产生可能是我最近不断的调试配置文件,修改内外网地址,重启引起的。
