mysql 从服务器在主服务器发出每个复制请求后停止

Question

基本的主从MySQL配置已经在Windows机器上完成。主服务器和从服务器在具有不同端口的本地主机上运行。

现在在主服务器中执行更新或插入时，从服务器会在该事件后停止。重新启动从属服务器并检查更新后，update/insert 通过复制设置在从属服务器中成功执行。

此问题的可能根本原因是什么？

Answer 1

发现不同 MySQL 服务器版本存在问题。主服务器运行 MySQL 版本 5.7.8，从服务器 MySQL 版本为 5.6.10。

已将主从版本同步到 5.6.26。复制在没有停止从属服务器的情况下工作正常。
