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

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= 

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";
