问题描述

我已经在本地 XAMPP 服务器上安装了 Drupal.它一切正常，在我重新启动 XAMPP 之前，包含和使用数据库/站点没有问题.从那时起，我在我的日志文件中得到以下信息:

I've installed Drupal on my local XAMPP Server. It worked all fine, no problems with including and working with the database/site till i restarted XAMPP. Since then I get the following at my logfile:

InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf

InnoDB:并在此处强制 InnoDB 继续崩溃恢复.

InnoDB: and force InnoDB to continue crash recovery here.

我通过 google 寻找了一个解决方案，但似乎只是 Drupal 数据库有问题，因为如果我删除数据库，它可以与 MySQL 连接.

I looked for a solution via google but it seems to be a problem just with the drupal database because it's able to connect with MySQL if I remove the database.

我希望有人能帮助我:(.

I hope someone could help me :(.

推荐答案

dev_khan,尝试在启用 innodb_force_recovery 选项的情况下以只读模式重新启动 MySQL:

dev_khan, try restarting MySQL in Read-Only mode with the innodb_force_recovery option enabled:

1. 编辑 my.cnf - 找到该行:# innodb_force_recovery = 2
2. 注释掉(去掉#)
3. 重启 MySQL 让 MySQL 引擎自行修复.
4. 再次注释 innodb_force_recovery 行(添加 #)
5. 再次重启 MySQL，您就可以再次获得完全访问权限，而没有只读限制.
