mysql備份錯誤

這個報錯是指此用戶沒有權限
mysqldump: Got error: 1449: The user specified as a definer ('admin'@'%') does not exist when using LOCK TABLES

解決方法：
mysql> GRANT select, lock tables ON dbname.* TO 'admin'@'%';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

添加以上兩條即可
