==> Pouring mysql-5.7.20.sierra.bottle.tar.gz
==> /usr/local/Cellar/mysql/5.7.20/bin/mysqld --initialize-insecure --user=sweet
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
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
