启动zk后启动kafka
jpsall以后 发现两个进程都启了这里有猫腻kafka其实没起来过几秒就自动掉了但我以为正常起了
我再启动kafka的查看主题
bin/kafka-topics.sh --bootstrap-server hadoop102:9092 --list
【控制台打印报错日志】
Connection to node -1 (hadoop102/172.17.0.16:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
他说我的节点不可用我又用jpsall看了下我的三台节点的kafka果然都自动毙掉了我又去kafka的log下看日志
【kafka的log目录下的报错日志】[2024-04-13 08:42:36,154] WARN Session 0x0 for server hadoop102/172.17.0.16:2181, Closing socket connection. Attempting reconnect except it is a SessionExpiredException. (org.apache.zookeeper.ClientCnxn)

这个错误表明你的应用程序尝试与Kafka集群中地址为hadoop102主机名、IP地址为172.17.0.16IP的节点代理通信通过9092端口但是无法建立连接。这可能是由于网络问题、代理服务未运行、错误的配置或者防火墙设置等原因造成的。排查原因我kafka没起来是因为Zookeeper没起成功
【Zookeeper里的log目录报错日志】

百度后给的解决方案是防火墙没关网络连接异常客户端和服务器版本不匹配参数配置问题行吧那就一个一个试
1.先关三台机器防火墙systemctl stop firewalld 都关了
2.在试三台节点网络是否通畅ping hadoop103 正常
3.版本这个不太可能因为别人都用这两个版本没报这个错所以应该不是这个问题
4.配置问题查看kafka的server.propertis文件查看broker.id查看advertised.listenerszookeeper.connect三个参数都正常上述四项检查了都没问题重启Zookeeperkafka发现还是起不来娘希匹
5.难道是腾讯云的问题/etc/hosts将上面那一堆乱七八糟的注释掉分发重启三台zkkafka。成功
