我有一个 docker-compose 文件,我在其中使用官方mysql:latest
图像作为我的数据库服务器。
在 adocker pull mysql
和 a之后docker-compose up
,图像从5.7 -> 8.0.11更新
此更新损坏了我所有的 mysql 数据。
所有.frm
文件都被删除了。
当我尝试重新启动 mysql-server 时,我收到以下错误,即使使用innodb_force_recovery [1-6]

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68195 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

我已经搜索了如何从现有.ibd
文件中恢复数据的解决方案,但没有任何效果。
到目前为止我尝试过的
由于我有数据库的本地副本,但数据过时,我希望我能以某种方式重新导入数据。
1.尝试重构表并将.ibd
文件导入表空间:
- 创建了一个单独的mysql实例
CREATE DATABASE new_db; USE new_db;
CREATE TABLE wp_options(...)
根据我拥有的本地转储创建表的结构。alter table wp_options discard tablespace
wp_options.ibd
将我要恢复的内容复制到new_db
文件夹中alter table wp_options import tablespace
.
它给了我5.7
错误:
ERROR 1815 (HY000): Internal error: Cannot reset LSNs in table `dnmc`.`wp_options` : Unsupported``
在8.0.11
服务器上只是崩溃。
2.创建表空间并将其分配给表
所以我跑:
CREATE TABLESPACE wp_options ADD DATAFILE "/var/lib/mysql/dnmc_orig/wp_options.ibd" Engine=InnoDB;
这给了我以下错误,无论是 on5.7
和8.0.11
.
ERROR 3121 (HY000): Incorrect File Name '/var/lib/mysql/dnmc_orig/wp_options.ibd'.
