  • 根据.frm .ibd文件恢复表

    恢复思路:

    1、使用dbsake获取建表语句

    https://github.com/abg/dbsake

    2、使用mysql表传输功能

    https://dev.mysql.com/doc/refman/8.0/en/innodb-table-import.html

    恢复步骤:

    1、根据github下载安装dbsake

    root@ip-172-31-30-45:~# curl -s get.dbsake.net > dbsake
    root@ip-172-31-30-45:~# chmod u+x dbsake

    2、获取 .frm 文件表结构,并到数据库中建表

    root@ip-172-31-30-45:~# ./dbsake frmdump ./tt.frm 
    --
    -- Table structure for table `tt`
    -- Created with MySQL Version 5.7.34
    --
    
    CREATE TABLE `tt` (
      `id` int(11) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    
    root@ip-172-31-30-45:~# 



    mysql> CREATE TABLE `tt` (
    -> `id` int(11) NOT NULL,
    -> PRIMARY KEY (`id`)
    -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    Query OK, 0 rows affected (0.01 sec)

    mysql>

    3、卸载tt 表

    mysql> alter table tt discard tablespace;
    Query OK, 0 rows affected (0.00 sec)

    4、拷贝 tt.ibd 到数据目录 

    root@ip-172-31-30-45:/usr/local/mysql57/data/ceshi# cp /root/tt.ibd /usr/local/mysql57/data/ceshi

    5、导入 tt 表

    mysql> alter table tt import tablespace;
    Query OK, 0 rows affected, 1 warning (0.03 sec)

    6、查询数据

    mysql> select * from tt;
    +----+
    | id |
    +----+
    |  2 |
    |  3 |
    |  4 |
    +----+
    3 rows in set (0.00 sec)
