Two extra tips when you try to (manually) bootstrap MySQL on Windows from the command line:
The first point really bugged me yesterday. I’m used to installing MySQL manually and having no option files available where MySQL would read them by default.
On Windows, however, I used the MySQL installer. So, when I launch unit testing for Connector/Python it bugged me saying log files of InnoDB didn’t match the configuration. This is indeed a newbie error..
