MySQL XAMPP 中的数据库已停止
MySQL Database in XAMPP is stopped
我在 运行 Xampp Linux(Ubuntu 14.04) 一切正常，直到一个小时前我突然关闭它开始抛出这个错误。
错误：
MySQL said: Documentation
Cannot connect: invalid settings.
Connection for controluser as defined in your configuration failed.
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

不幸的是，这看起来不像是个好消息。
根据您发布的错误日志，myshop 数据库中的 mobile12 table 似乎已损坏，这就是 MySQL 的原因不会开始。共有三个建议的解决方案：
1) If there is a permission problem in the file and mysqld cannot open the file, you should modify the permissions.
检查 MySQL 数据目录（可能是 /opt/lampp/var/mysql 中的文件 ./myshop/mobile12.ibd 的权限。将您找到的内容与数据目录中其他子目录中的其他文件进行比较。
2) If the table is not needed, or you can restore it from a backup, then you can remove the .ibd file, and InnoDB will do a normal crash recovery and ignore that table.
删除 ./myshop/mobile12.ibd 文件。请注意，删除它会将其从您的数据库中销毁，因此您需要从备份中恢复。假设您有最近的备份，这很可能是最佳解决方案。
3) If the file system or the disk is broken, and you cannot remove the .ibd file, you can set innodb_force_recovery > 0 in my.cnf and force InnoDB to continue crash recovery here.
我不太清楚这里的评论是什么意思，如果它意味着设置 innodb_force_recovery 将尝试从损坏的文件中恢复数据，或者它是否会解决该文件并尝试自动删除它.
删除损坏的 .idb 文件后，守护程序应该会再次正常启动。很抱歉这个坏消息，但这应该会让你再次前进。
