在MySQL 5.11上的CentOS 5.0上,MySQL服务已经崩溃,无法启动。在/etc/my.cnf中添加innodb_force_recovery=3将创建以下错误,该错误将重复数据库DBNAME的所有表名:

服务器崩溃后(Ubuntu16.04),当我尝试使用innodb_force_recovery=0启动Mysql (MySQL5.7)时,它没有启动,error.log显示:

关于我的,我的MySQL出了点问题。
我最近需要从MySQL中删除一个表,现在需要在原来的位置创建一个新表。我很难做到这一点,因为正如MySQL工作台所说,“这个表已经存在了。”由于来自MySQL工作台的错误没有什么特别的帮助,下面是我从错误日志中提取的一些内容。有什么问题吗?
我在Windows8.1Pro x64上运行MySQL 5.7。

可以通过以下方式更改特定表的存储引擎类型:
ALTER TABLE table_name ENGINE = InnoDB;
这适用于MariaDB/MySQL安装附带的所有表,但db、host和user表除外。它引发一个(泛型)错误:

我在15个数据库中有大约6000个InnoDB表,使用innodb_file_per_table时,我发现每次重新启动Ubuntu服务器时,MySQL都会出现错误。

我已经用MySQL企业“联机备份”选项配置了生产MySQL数据库。配置已顺利通过。当分配的调度程序尝试进行备份时,下面会提到来自MySQL数据库的日志错误。
一切都很好,就像MySQL表一样,因为这是我的生产数据库。我在MySQL数据库中有44个表,大部分表在INNODB引擎中,还有MyISAM引擎。
