I think some would also want to know how to find the my.ini file on your PC. For windows users, I think the best way is as follows:

2. You could find an entry like 'MySQL56', right click on it, select properties
3. You could see sth like "D:/Program Files/MySQL/MySQL Server 5.6/bin\mysqld" --defaults-file="D:\ProgramData\MySQL\MySQL Server 5.6\my.ini" MySQL56
