这篇文章主要介绍如何利用innobackupex备份集恢复指定库，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
1.源库导出表结构
mysqldump -uroot -p --no-data zabbix > info.sql
2.创建要恢复的库、表
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> use zabbix;
mysql> source info.sql
3.查看外键约束
mysql> SELECT @@FOREIGN_KEY_CHECKS;
+----------------------+
| @@FOREIGN_KEY_CHECKS |
+----------------------+
| 1 |
+----------------------+
1 row in set (0.00 sec)
查看要迁移的表是否有外键约束：
mysql> select * from information_schema.TABLE_CONSTRAINTS where table_schema = 'zabbix' and constraint_type = 'FOREIGN KEY';
如果有的话，禁用外键：
mysql> SET FOREIGN_KEY_CHECKS=0;
Query OK, 0 rows affected (0.00 sec)
4.库中的表进行discard tablespace
mysql> select concat('alter table ',table_name,' discard tablespace;') from information_schema.tables where table_schema = 'zabbix';
mysql> alter table acknowledges discard tablespace;
Query OK, 0 rows affected (0.00 sec)
mysql> alter table actions discard tablespace;
Query OK, 0 rows affected (0.00 sec)
......
然后重新启用外键约束：
mysql> SET FOREIGN_KEY_CHECKS=1;
Query OK, 0 rows affected (0.00 sec)
5.将apply-log后的备份集中表的ibd文件拷贝到数据目录下并修改权限：
cp *.ibd /opt/app/mysql/mysql5722/data/zabbix/
chown -R mysql.mysql /opt/app/mysql/mysql5722/data/zabbix/*
6.库中的表进行import tablespace
mysql> select concat('alter table ',table_name,' import tablespace;') from information_schema.tables where table_schema = 'zabbix';
如果报错：ERROR 1808 (HY000): Schema mismatch (Table has ROW_TYPE_DYNAMIC row format, .ibd file has ROW_TYPE_COMPACT row format.)
则修改表的row_format：
mysql> select concat('alter table ',table_name,' row_format=compact;') from information_schema.tables where table_schema = 'zabbix';
注意：修改表的row_format后，要重新进行第5步
