Question

我尝试重新启动，并收到此错误：

ERROR！无法找到MySQL服务器PID文件！启动MySQL。错误！服务器退出而不更新PID文件（/var/lib/mysql/www.mysitecom.pid）。

查看日志..请参阅大量内容：

能够通过将innodb_force_recovery = 4添加到sql配置文件来重新启动，但是所有触摸数据库的站点现在都已损坏且无法写入。

当我尝试对所有表进行mysql转储时，我收到错误：

mysqldump: Got error: 1146: Table 'x3hmcpl_hmcpl.blocked_ips' doesn't exist when using LOCK TABLES

任何帮助都将不胜感激。我们这里没有数据库人员，我一直在努力尽快修复它。

Answer 1

innodb_force_recovery = 4将InnoDB置于只读模式，它不应该修复损坏的InnoDB表空间。

转储所有数据库（mysqldump -A＆gt; mydb.sql）并重新创建MySQL datadir。

数据库崩溃，需要帮助恢复
