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;

If you're running on Ubuntu, you may also need to configure Apparmor to allow MySQL to write to your folder, e.g. here's my configuration:

Add this line to file /etc/apparmor.d/usr.sbin.mysqld :

/var/lib/mysql-files/* rw

Then add these 2 config lines to /etc/mysql/my.cnf sections:

[client]
loose-local-infile = 1

[mysqld]
secure-file-priv = ""

Here's my SQL:

select id from blahs into outfile '/var/lib/mysql-files/blahs';

It worked for me. Good luck!
