Issue Description

线上环境使用了很久，今天看日志突然同步不了。看了日志是9月24的，后面就没有日志了。没看到有什么报错.需要我提供什么日志排查？ adapter: deployer:

Actual behaviour

If there is an exception, please attach the exception trace:

Just put your stack trace here!

[dyrnq]

可以查一下deployer的 ${instance}的日志

[wuwei0727]

我的deployer日志只有这些。我看了里面没有报错信息

[dyrnq]

example就是instance，进example目录看看

[wuwei0727]

example.log我看了，我没看见有什么报错

[dyrnq]

是怎么运行的，确认这服务还正常跑着么？

[wuwei0727]

直接运行bin目录下的sh文件。线上环境跑了很久之前没问题。测试发现问题，我去看日志发现只有9.24的，后面的就没了，也没发现任何报错信息。

[dyrnq]

ps命令 查下java进程是否还在运行中呢，这个启动后&推倒后台了

## server
ps aux | grep CanalLauncher |grep -v grep

## adapter
ps aux | grep CanalAdapterApplication|grep -v grep

[wuwei0727]

都没有。我不知道是什么原因导致停止了。有日志可以看原因？

[dyrnq]

这种情况只能查查系统日志了，比如/var/log下的

[wuwei0727]

好的谢谢。我重启canal服务。会读取之前的binlog没同步的数据？

[dyrnq]

为了避免java崩溃，可以采取以下措施

• 自己配置下systemd unitfile把进程启动管理起来,并配置开机启动以及崩溃重启
• java options增加-XX:HeapDumpPath等参数
• 普罗米修斯监控指标及时发现问题

[dyrnq]

好的谢谢。我重启canal服务。会读取之前的binlog没同步的数据？

按道理，预期是得接着读啊

[wuwei0727]

[wuwei0727]

读取不到binlog文件？

[dyrnq]

上数据库查1查show master status; 看看master的binlog日志有没有保留到mysql-bin.007826之前？

[dyrnq]

看你日志 mysql-bin.007815 没有的，直接跳到007826了？

你的example/目录下没有持久化的meta.data吗？

[wuwei0727]

我看了是有的，为什么会报错？

[wuwei0727]

[wuwei0727]

example.log里面全是这样的报错。

[dyrnq]

其他节点是不是还有实例也再跑？有没有连zookeeper?

[wuwei0727]

我这个是单机，没有其他机器跑

[dyrnq]

canal.instance.master.journal.name=mysql-bin.007815
canal.instance.master.position=0

把这个配置更新到 example/instance.properties, 重启看看行不

[dyrnq]

example/meta.data 有没有这个文件？

[wuwei0727]

meta.data有

[wuwei0727]

是把这删掉？

[dyrnq]

meta.data有

打开看看，不能删除呀呀，这个文件非常重要啊，记录的是同步到哪里了

[wuwei0727]

meta.data： {"clientDatas":[{"clientIdentity":{"clientId":1001,"destination":"example","filter":""},"cursor":{"identity":{"slaveId":-1,"sourceAddress":{"address":"192.168.1.95","port":3306}},"postion":{"gtid":"","included":false,"journalName":"mysql-bin.007826","position":61676899,"serverId":1,"timestamp":1727157518000}}}],"destination":"example"}

[dyrnq]

日志中断是mysql-bin.007815，meta.data记录是mysql-bin.007826，所以example会从mysql-bin.007826这里再继续

[dyrnq]

1727157518000=2024-09-24 13:58:38 说明程序后来又启动了

[wuwei0727]

我可以把完整的example.log发送给你吗？

[dyrnq]

把meta.data中的61676899改为61676926，重启试试

[wuwei0727]

好的我试试

[wuwei0727]

这个还需要改吗

[dyrnq]

不用

我按您说的修改了。

[dyrnq]

还有个方法 1，删除mate.data(做好备份） 2、修改example/instance.properties

canal.instance.master.journal.name=mysql-bin.007815
canal.instance.master.position=0

3、重启

但要确认是从哪个mysql-bin.xxxx 哪个文件开始

[wuwei0727]

meta.dat文件为什么每次修改后有变回去了

[dyrnq]

没变回，看日志又有个61676945

[wuwei0727]

journalName的这个需要改？我看了meta.dat已经改成61676926

[dyrnq]

journalName

mate.data的 journalName？

[wuwei0727]

是的

[wuwei0727]

现在报错。读取不到binlog文件。不知道哪里问题。改成了61676926。还是不行

[wuwei0727]

是需要把mate.data删除重新读？

[dyrnq]

是需要把mate.data删除重新读？

这个是不得已的办法

[wuwei0727]

非常感谢！您的耐心帮助
