MySQL5.7_macOS_High_Sierra.md

1. Follow this: https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe13.

   Note: mysql is already at v8.0.11 as of this point of writing, so make sure you explicitly install v5.7 by replacing mysql with mysql@5.7.

2. Create a new entry into your PATH environment as the postinstall note suggests:

   # Edit the Terminal startup configuration file.
   open ~/.bash_profile
   
   # Copy this into the file and save.
   export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"
   
   # Apply the new Terminal startup configuration.
   source ~/.bash_profile
   

3. Run mysql_secure_installation now that it's an available command.
