Nitro is no longer supported. Please see our announcement and DDEV migration guide.

# mysql.conf

You can customize Nitro’s MySQL settings by editing mysql.conf and restarting the MySQL service:

  1. Tunnel into the machine with nitro ssh.
  2. Apply your changes to ~/.nitro/databases/mysql/conf.d/mysql.conf.
  3. Exit the machine tunnel by running exit.
  4. Restart MySQL using nitro db restart.


If you add a NITRO_EDIT_HOSTS environment variable to your system and set it to false, Nitro will never edit the hosts file on the host machine.

This is useful for people running some host file manager applications.
