Question

我正在使用mySql server 5.7，自安装以来它运行良好。但是，在周末最新的Windows 10主页更新后，服务器似乎无法启动（通过mySql通知程序或通过mySql Workbench）

感谢任何帮助。

以下是mySQL工作台上错误日志文件的屏幕截图。screenshot of error log file

请帮帮我。

此外，这是我尝试从工作台应用程序启动服务器时获得的启动消息日志。

Answer 1

我不知道原因，但更新后删除了MySql的服务。但您可以按照以下步骤备份DataBase：

转到＆＃34; MySql目录＆＃34; / bin。

执行 mysqld.exe 文件。（它将打开MySql临时的＆＃39;实例。）

然后您必须使用以下脚本创建输出 .bat 文件：

/＆＃34; MySql目录＆＃34; / bin / mysqldump -u root -p＆＃34; 密码＆＃34; -P＆＃34; 端口＆＃34; ＆＃34; Schemma的名字＆＃34; ＆GT; C：/＆＃34; 某些输出目录＆＃34; /dump.sql

现在您已经备份了dump.sql文件

创建新的MySql服务时，要恢复数据，请执行以下操作来恢复数据：

使用以下脚本创建输入 .bat 文件：

/＆＃34; MySql目录＆＃34; / bin / mysql -u root -h 127.0.0.1 -p＆＃34; 密码＆＃34; -P＆＃34; 端口＆＃34; ＆＃34; Schemma的名字＆＃34; ＆LT; C：/＆＃34; 输出目录＆＃34; /dump.sql

忽略＆＃34;＆＃34;。

您的MySql是否默认安装在默认目录上？

Anynone知道Windows Update崩溃MySql服务的原因吗？

Answer 2

我可以建议备份您的现有数据。然后重新安装。

停止mysqld.exe [结束任务]

更新文件[my.ini]

[mysqld]

innodb_force_recovery = 4;

-您可以填写（1/2/3/4/5/6）

启动服务MYSQL57

-导出数据库

-Reisntall Mysql

最新更新后，Mysql server 5.7无法在Windows 10上启动
