发生连接重置 - 编程之家

如何解决发生连接重置

我正在尝试使用 MysqL 解决“连接重置”问题。我怀疑 MysqL(5.7.34) 服务器终止了连接。但是根据我的调查，在binlogReader中已经配置了KeepAlive和HearBeat。所以我想知道为什么会发生这种连接重置。
MysqL 连接器在 2021-07-14 15:26:00 左右成功启动，在 debezium 引擎中使用“debezium-connector-MysqL-1.3.1.Final VERSION”。
它在 2021-07-15 18:17:58.091 停止，带有“连接重置”
还有什么需要我看的吗？
提前致谢。
