如何解决“错误:MySQL关机意外”?

当我打开XAMPP并单击启动MySQL按钮时，它给了我一个错误。我刚才启动了它，但现在它不工作了。

最重要的错误信息在这里:

日志的其余部分:

这些错误的原因是什么?我该如何纠正它们?

当前回答

我打开并清空存在于数据文件夹中的文件multi-master.info。这对我很管用。

其他回答

步骤01:如果启动XAMPP MySQL时出现错误，按照以下步骤轻松解决这个问题。

步骤02:停止服务器并进入配置。

步骤03:打开my.ini文件。

步骤04:在记事本文本中找到这2个端口号。

步骤05:更改这两个端口号3306—> 3308或任何其他数字。

使用Ctrl+S保存文本文件后

步骤07:转到XAMPP安装文件夹并打开XAMPP文件夹。步骤08:找到phpMyAdmin文件夹。

步骤09:打开phpMyAdmin文件夹，找到config.inc.php文件。

步骤10:Change Here端口号之前您在步骤05中修改的端口号。(如3008)和保存此文本文件。

步骤11:关闭所有文件后，转到XAMPP服务器。

步骤12:再次启动MySQL服务器。

步骤13:打开浏览器，输入URL——>> localhost 步骤14:进入PhpMyAdmin

步骤15:phpMyAdmin is Working normal Now。

如果启动Apache服务器时出现错误，

步骤01:停止服务器，并打开配置文件。

步骤02:在文本文件中找到这个Listen数字。

步骤03:将80更改为8000或任何其他值。并保存文本文件。

步骤04:保存文本文件后，打开XAMPP服务器并再次启动Apache服务器。

打开你的网页浏览器。步骤06:输入localhost:8000

步骤07:现在你可以打开phpMyAdmin。

注意:更改Apache端口号后，必须在URL中的localhost:后面添加。

对我来说，问题是:

由于项目规模太大，我习惯将电脑休眠，而不是关闭。我太懒了，重新打开了所有程序。

在尝试其他方法之前，我建议您做以下简单的事情。否则，你的MySQL服务器就会一团糟。

打开任务管理器并结束XAMPP进程。以管理员身份重新运行XAMPP应用程序。

如果不行，

保存所有未保存的程序，重新启动电脑。以管理员身份运行XAMMP。

另外，一定要检查3306和5040端口。在默认设置下运行MySQL需要这两个端口。

查看@Ryan Williams的回答，了解为什么作为管理员运行XAMPP很好。

对我有用的是(不删除文件):

首先，我在XAMPP面板中打开MySql日志。最后，它说您正在3306端口运行mysqlid的另一个实例我打开我的任务管理器(Ctrl+Shift+Esc)，然后找到mysqlid和结束任务。

我尝试了上面所有的答案，但对我来说都不管用。所以最后我尝试了下面的方法，它100%适合我。

如果您担心无法执行以下步骤，为安全起见，您可以对整个XAMPP文件夹进行备份。

第一步:将c:\xampp\mysql\data文件夹重命名为c:\xampp\mysql\data_bkp

新建文件夹c:\xampp\mysql\data。

第三步:复制c:\xampp\mysql\backup中的内容到新的c:\xampp\mysql\data文件夹中。

第四步:复制所有数据库文件夹c:\xampp\mysql\data_bkp到c:\xampp\mysql\data(注意:不要复制mysql、performance_schema和phpmyadmin文件夹)。

步骤5:从c:\xampp\mysql\data_bkp复制ibdata1文件，并将其替换到c:\xampp\mysql\data文件夹中。

步骤6:从XAMPP控制面板启动MySQL。

There are a number of things I've tried. This is the 2nd time this has happened to me. On my first time, I've to reinstall my xampp. And on the third day, mysql crashed again. I've tried everything I found on the internet. Like, innodb_flush_method=normal in my.ini file and deleting ibdata1, ib_logfile1, ib_logfile0 files, and others but none of these works. So later I tried to run xampp with admin privilege and install apache and mysql as a service as it was instructed on xampp control panel itself. After starting mysql, I read error-log again and from there I came to know that one of my databases is responsible for this. That database file won't let mysql start. So I deleted everything in the data folder and then in cmd I navigated to C:/xampp/mysql/bin path and ran these commands:

mysqld——初始化

mysql_install_db

mysql又开始运行了。但是我的数据库和数据丢失了。
