transportable tablespace
实验环境：
源端：192.168.99.111
目标端：192.168.99.112
源端test1.actor–>目标端test2.actor
transportable tablespace的应用场景、限制及注意事项，具体请参考官方手册
https://dev.mysql.com/doc/refman/5.7/en/tablespace-copying.html#innodb-transportable-tablespace-limitations
Example 1: Copying an InnoDB Table to Another Instance
1、准备环境
源端：

1 row in set (0.00 sec)2、在目标端DISCARD TABLESPACE
[root@centos7 data]# cd /data/mysql/mysql3306/data/test2
[root@centos7 test2]# ll

[root@centos7 test2]# mysql -p

-rw-r----- 1 mysql mysql 8694 Jun 19 14:51 actor.frm
-rw-r----- 1 mysql mysql 61 Jun 19 14:49 db.opt3、在源端FLUSH TABLES … FOR EXPORT
root@localhost:mysql3306.sock [(none)]>use test1;
Database changed
root@localhost:mysql3306.sock [test1]>flush tables actor for export;
Query OK, 0 rows affected (0.01 sec)
注意：执行完此命令后不要退出连接，另打开一个连接执行scp操作4、从源端把.ibd和.cfg copy到目标端
[root@centos7 ~]# cd /data/mysql/mysql3306/data/test1
[root@centos7 test1]# ll
total 240
-rw-r----- 1 mysql mysql 649 Jun 19 15:05 actor.cfg

-rw-r----- 1 mysql mysql 8556 Jun 18 22:02 test1.frm
-rw-r----- 1 mysql mysql 98304 Jun 18 22:02 test1.ibd
[root@centos7 test1]# scp /data/mysql/mysql3306/data/test1/actor.{cfg,ibd} 192.168.99.112:/data/mysql/mysql3306/data/test2/

root@localhost:mysql3306.sock [(none)]>use test1;
Database changed
root@localhost:mysql3306.sock [test1]>unlock tables;
Query OK, 0 rows affected (0.00 sec)6、在目标端import tablespace
[root@centos7 test2]# ll
total 132
-rw-r----- 1 root root 649 Jun 19 15:08 actor.cfg
-rw-r----- 1 mysql mysql 8694 Jun 19 14:51 actor.frm

1 row in set (0.00 sec)对于一个普通的InnoDB表进行传输表空间操作到此就算结束了，很简单实用，在MySQL5.7版本开始支持分区表，更多示例请参考MySQL官方手册
