==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation

To connect run:
mysql -uroot

To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
