How should I tackle --secure-file-priv in MySQL?

Question

I am learning MySQL and tried using a LOAD DATA clause. When I used it as below:

LOAD DATA INFILE \"text.txt\" INTO table mytable;

Answer 1

MySQL use this system variable to control where you can import you files

mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| secure_file_priv | NULL  |
+------------------+-------+

So problem is how to change system variables such as secure_file_priv.

1. shutdown mysqld
2. sudo mysqld_safe --secure_file_priv=""

now you may see like this:

mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| secure_file_priv |       |
+------------------+-------+

Answer 2

This worked for me (had the additional problem of not being able to use LOCAL with my current MySQL version in the statement LOAD DATE INFILE ... )

sudo /usr/local/mysql/support-files/mysql.server start --secure-file-priv='' --local-infile

The above works for that given path on my machine; you may have to adjust your path.

Then use:

mysql -u root -p

One important point is that you should have the CSV in the MySQL data folder. In my machine it is located at: /usr/local/mysql-8.0.18-macos10.14-x86_64/data

You can change the folder permission if needed to drop a CSV in the data folder.

Setup:
macOS Catalina version 10.15.5
MySQL version 8.0.18

Answer 3

If the file is local to your machine use the LOCAL in your command

LOAD DATA LOCAL INFILE "text.txt" INTO table mytable;

Answer 4

@vhu I did the SHOW VARIABLES LIKE "secure_file_priv"; and it returned C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\ so when I plugged that in, it still didn't work.

When I went to the my.ini file directly I discovered that the path is formatted a bit differently:

C:/ProgramData/MySQL/MySQL Server 8.0/Uploads

Then when I ran it with that, it worked. The only difference was the direction of the slashes.

in Linux you have to edit my.cnf file in

/etc/mysql/my.cnf

and change 26 line number param like this :

secure-file-priv= <your data path directory like /home/user/data>

then restart your MySQL and try again.

in docker you have to mount your my.cnf file with my.cnf file in your container with this command in docker-compose or add manually :

volumes:
  - ./persistent:/var/lib/mysql
  - ./conf/my.cnf:/etc/mysql/my.cnf

next change /conf/my.cnf in your host and config secure-file-priv param like the upper approach, in addition, you have to mount your data in mysql container and set that path for secure-file-priv param and restart your services and finally, you can load your data.

you can check your config with this command :

SHOW VARIABLES LIKE "secure_file_priv";

I had this problem on windows 10. "--secure-file-priv in MySQL" To solve this I did the following.

1. In windows search (bottom left) I typed "powershell".
2. Right clicked on powershell and ran as admin.
3. Navigated to the server bin file. (C:\Program Files\MySQL\MySQL Server 5.6\bin);
4. Typed ./mysqld
5. Hit "enter"

The server started up as expected.
