- copy the CSV file to the DB folder (/var/lib/mysql/DATABASE), and
- use the filename only, not the full path.
If you're having troubles with LOAD DATA LOCAL INFILE ("The used command is not allowed with this MySQL version"):
- temporary solution: mysql -uUSER -p --local-infile DATABASE
- permanent solution: sudo nano /etc/mysql/my.cnf and insert local-infile under [mysql]; save the file, close the editor and type sudo service mysql restart.
Note: LOAD DATA LOCAL INFILE uses IGNORE. If you want to know why some records were skipped, you must use LOAD DATA INFILE (without LOCAL). (Reference)
