利用innobackupex备份集恢复指定库

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
