Mysql 将 --secure-file-priv 选项设置为 NULL

Question

我在 Ubuntu 中运行 MySQL。我在运行特定查询集时收到此错误。

MySQL 服务器正在使用 --secure-file-priv 选项运行，因此它无法执行此语句

当我SELECT @@secure_file_priv;在我的 mysql 服务器上做的时候，我得到了/var/lib/mysql-files/. 我想我需要做到这一点NULL。

这是我正在运行的查询：

LOAD DATA INFILE :file INTO TABLE test_files
COLUMNS TERMINATED BY ',' ENCLOSED BY '\"'
LINES TERMINATED BY '\n';

现在的问题是如何做到这一点NULL？

Answer 1

尝试：

mysql> SELECT VERSION();
+-----------+
| VERSION() |
+-----------+
| 5.7.12-0  |
+-----------+
1 row in set (0.00 sec)

mysql> SELECT @@GLOBAL.secure_file_priv;
+---------------------------+
| @@GLOBAL.secure_file_priv |
+---------------------------+
| /var/lib/mysql-files/     |
+---------------------------+
1 row in set (0.00 sec)

更改文件：/etc/mysql/my.cnf

[mysqld]
.
.
.
secure_file_priv=NULL
.
.
.

重新启动 MySQL。

mysql> SELECT @@GLOBAL.secure_file_priv;
+---------------------------+
| @@GLOBAL.secure_file_priv |
+---------------------------+
| NULL                      |
+---------------------------+
1 row in set (0.00 sec)

更新

mysql> SELECT @@GLOBAL.secure_file_priv;
+---------------------------+
| @@GLOBAL.secure_file_priv |
+---------------------------+
| /var/lib/mysql-files/     |
+---------------------------+
1 row in set (0.00 sec)

文件：/var/lib/mysql-files/myfile.csv

1,"Row 1"
2,"Row 2"
3,"Row 3"

mysql> DROP TABLE IF EXISTS `test_files`;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> CREATE TABLE IF NOT EXISTS `test_files` (
    ->   `col0` INT,
    ->   `col1` VARCHAR(20)
    -> );
Query OK, 0 rows affected (0.00 sec)

mysql> LOAD DATA INFILE '/var/lib/mysql-files/myfile.csv'

    -> LINES TERMINATED BY '\n';

mysql> SELECT
