==> 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
mysql@5.7 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have mysql@5.7 first in your PATH run:
echo 'export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"' >> ~/.zshrc
For compilers to find mysql@5.7 you may need to set:
export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib"
export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"
To have launchd start mysql@5.7 now and restart at login:
brew services start mysql@5.7
Or, if you don't want/need a background service you can just run:
/usr/local/opt/mysql@5.7/bin/mysql.server start
