来自网页管理员：

#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)

每次访问DB时，据我所知，它都会崩溃。

Answer 1

由于硬盘错误，MySQL无法读取数据库的部分内容。

mysqldump也会因此而失败。

最后，我编写了一个python脚本来提取Innodb数据库中所有可读的部分。

总结如下：

1. 带有dd (http://www.thegeekstuff.com/2010/10/dd-command-examples/)的img硬盘驱动器
2. 通过mysqldump备份数据库(使用python脚本跳过不可读性)
3. 引进新系统

Answer 2

根据您所说的，您是否试图对数据库信息所在的磁盘执行强制的完整fsck操作？

Answer 3

重新启动MySQL后重新启动webmin。取决于您的分布，它可能是

service webin restart

或

/ect/init.d/webin restart
