MySQL 5.6.26 通過frm & ibd 恢復數據過程

在A服務器上創建數據庫yoon
root(yoon)> show create table yoon\G
*************************** 1. row ***************************
Table: yoon
Create Table: CREATE TABLE `yoon` (
`id` int(11) DEFAULT NULL,
`name` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8

插入數據
root(yoon)> insert into yoon values (1,'HANK');
Query OK, 1 row affected (1.01 sec)

root(yoon)> insert into yoon values (2,'YOON');
Query OK, 1 row affected (0.04 sec)

root(yoon)> insert into yoon values (3,'GARY');
Query OK, 1 row affected (0.00 sec)

root(yoon)> insert into yoon values (4,'NIKO');
Query OK, 1 row affected (0.02 sec)

root(yoon)> select * from yoon;
+------+------+
| id | name |
+------+------+
| 1 | HANK |
| 2 | YOON |
| 3 | GARY |
| 4 | NIKO |
+------+------+
4 rows in set (0.00 sec)

在B服務器上，添加參數innodb_force_recovery=1並重啟，創建空數據庫yoon，並創建表yoon
mysql> create database yoon;
use yooQuery OK, 1 row affected (1.01 sec)

mysql> use yoon;
Database changed
mysql> CREATE TABLE `yoon` (
-> `id` int(11) DEFAULT NULL,
-> `name` varchar(20) DEFAULT NULL
-> ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Query OK, 0 rows affected (0.09 sec)

將表結構和空間脫離
mysql> alter table yoon discard tablespace;
Query OK, 0 rows affected (0.02 sec)

將A服務器上的ibd數據文件傳輸至B服務器上
scp yoon.ibd 182.19.4.7:/export/data/mysql/data/yoon

修改權限
chown -R mysql.mysql yoon.ibd

將表結構和空間建立關系
mysql> alter table yoon import tablespace;
Query OK, 0 rows affected, 1 warning (0.04 sec)

查詢數據
mysql> select * from yoon;
+------+------+
| id | name |
+------+------+
| 1 | HANK |
| 2 | YOON |
| 3 | GARY |
| 4 | NIKO |
+------+------+
4 rows in set (0.00 sec)

詳細步驟如下：
1、停止mysql服務，添加innodb_force_recovery=1 ，啟動mysql服務
2、創建新數據庫，創建相同表結構的表（表結構必須相同）
3、執行alter table tb discard tablespace;
4、刪除表的ibd文件
5、跨服務器復制表ibd文件
6、修改ibd文件權限,執行alter table tb import tablespace;
