Information is very rare on things like restarting MySQL. This is a note to anyone that may need this in the future.
The accepted installations for web development tools on a Mac is HomeBrew and to some extent Mac Ports. Here are two ways to restart installations for both types of installations:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo launchctl unload -w /Library/LaunchDaemons/org.macports.mysql.plist sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql.plist
