Question

基本主从MySQL配置已在Windows机器上完成。主服务器和从属服务器在具有不同端口的localhost上运行。

现在，当在主服务器中执行更新或插入时，从属服务器在该事件之后停止。重新启动从属服务器并检查更新后，通过复制设置在从属服务器上成功执行update / insert。

这个问题可能的根本原因是什么？

Answer 1

发现不同MySQL服务器版本的问题。主服务器在MySQL版本5.7.8上运行，从属MySQL版本在5.6.10。

将Master和Slave版本同步到5.6.26。复制工作正常，没有从服务器停止。

从Master获取每个复制请求后，mysql从服务器停止
