mysql中FILE权限

mysql> CREATE USER ‘filetest‘@‘localhost‘ IDENTIFIED BY ‘123456‘

FILE权限是对所有数据库文件而言的，因此数据库只能写成*.*，而不是某一个数据库
mysql> grant file on test3.* to ‘filetest‘@‘localhost‘;
ERROR 1221 (HY000): Incorrect usage of DB GRANT and GLOBAL PRIVILEGES

//赋予FILE权限
mysql> grant file on *.* to ‘filetest‘@‘localhost‘;
Query OK, 0 rows affected (0.00 sec)

//赋予select权限
grant select on test3.* to ‘filetest‘@‘localhost‘;
//刷新信息
flush privileges;

use test3;
mysql> select * from test2 into outfile ‘d:/test.txt‘
    -> ;
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv opti
on so it cannot execute this statement

//即使有了file权限，输出目录路径应该secure_file_priv一致
mysql> show variables like ‘%sec%‘
    -> ;

mysql> select * from test2 into outfile ‘e:/test/test.txt‘;
Query OK, 1 row affected (0.01 sec)

mysql> load data infile ‘e:/test/test.txt‘ into table test2;
ERROR 1142 (42000): INSERT command denied to user ‘filetest‘@‘localhost‘ for table ‘test2‘
//需要给filetest赋予insert权限

root用户上执行:
mysql> grant insert on test3.* to ‘filetest‘@‘localhost‘;
flush privileges;

filetest用户:
//infile的目录也要与secure_file_priv一致
mysql> load data infile ‘e:/test/test.txt‘ into table test2;
Query OK, 1 row affected (0.07 sec)
