1、源库查询表结构
mysql> show create table s_show\G *************************** 1. row *************************** Table: study_show Create Table: CREATE TABLE `study_show` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uid` int(11) DEFAULT ‘0‘ , `course_id` int(11) DEFAULT ‘0‘ , `ishow` tinyint(1) DEFAULT ‘0‘ , `album_id` int(10) DEFAULT ‘0‘ , `group_id` int(11) DEFAULT ‘0‘ , `task_id` int(11) DEFAULT ‘0‘ , `video` varchar(40) DEFAULT ‘‘ , `show_pic` int(11) DEFAULT ‘0‘ , `create_time` int(11) DEFAULT ‘0‘ , PRIMARY KEY (`id`), KEY `uid` (`uid`) USING BTREE, KEY `course_id` (`course_id`) USING BTREE, KEY `create_time` (`create_time`) ) ENGINE=InnoDB AUTO_INCREMENT=35230183 DEFAULT CHARSET=utf8 1 row in set (0.00 sec)
2、目标库创建表
mysql> CREATE TABLE `s_show` ( -> `id` int(11) unsigned NOT NULL AUTO_INCREMENT , -> `uid` int(11) DEFAULT ‘0‘ , -> `course_id` int(11) DEFAULT ‘0‘ , -> `ishow` tinyint(1) DEFAULT ‘0‘ , -> `album_id` int(10) DEFAULT ‘0‘ , -> `group_id` int(11) DEFAULT ‘0‘ , -> `task_id` int(11) DEFAULT ‘0‘ , -> `video` varchar(40) DEFAULT ‘‘ , -> `show_pic` int(11) DEFAULT ‘0‘ , -> `create_time` int(11) DEFAULT ‘0‘ , -> PRIMARY KEY (`id`), -> KEY `uid` (`uid`) USING BTREE, -> KEY `course_id` (`course_id`) USING BTREE, -> KEY `create_time` (`create_time`) -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ; Query OK, 0 rows affected (0.32 sec) mysql> desc s_show; +-------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+------------------+------+-----+---------+----------------+ | id | int(11) unsigned | NO | PRI | NULL | auto_increment | | uid | int(11) | YES | MUL | 0 | | | course_id | int(11) | YES | MUL | 0 | | | ishow | tinyint(1) | YES | | 0 | | | album_id | int(10) | YES | | 0 | | | group_id | int(11) | YES | | 0 | | | task_id | int(11) | YES | | 0 | | | video | varchar(40) | YES | | | | | show_pic | int(11) | YES | | 0 | | | create_time | int(11) | YES | MUL | 0 | | +-------------+------------------+------+-----+---------+----------------+ 10 rows in set (0.00 sec) mysql> select * from s_show; Empty set (0.00 sec)
3、目标库禁用表空间
mysql> alter table s_show discard tablespace; Query OK, 0 rows affected (0.05 sec)
4、源库锁定表
mysql> flush table s_show for export; Query OK, 0 rows affected (0.05 sec)
5、复制文件到目标库
[root@node01 mydb_1]# ls -alh|grep "s_show\." -rw-r----- 1 mysql mysql 1.2K Aug 10 11:52 s_show.cfg -rw-r----- 1 mysql mysql 8.9K Aug 9 14:02 s_show.frm -rw-r----- 1 mysql mysql 5.0G Aug 9 14:46 s_show.ibd [root@node01 mydb_1]# scp s_show.{cfg,ibd} root@10.10.1.103:/u01/mydata/mydb_1/ root@10.10.1.103‘s password: s_show.cfg 100% 1152 1.1KB/s 00:00 s_show.ibd 100% 5024MB 19.9MB/s 04:13
6、目标库导入表空间
修改文件权限 [root@node02 mydb_1]# chown -R mysql:mysql /u01/mydata/mydb_1/s_show.{cfg,ibd}
导入表空间(如果表很大会有很高的IO) mysql> alter table s_show import tablespace; Query OK, 0 rows affected (6 min 32.76 sec)
7、源库解除锁表
mysql> UNLOCK TABLES; Query OK, 0 rows affected (0.05 sec)
