Long story short you need to create a launch file. So, from Terminal:

sudo vi /Library/LaunchDaemons/com.mysql.mysql.plist

(If you are not familiar with vi, then press i to start inserting text)

This should be the content of your file:

 


  
    KeepAlive
    
    Label
    com.mysql.mysqld
    ProgramArguments
    
      /usr/local/mysql/bin/mysqld_safe
      --user=mysql
    
  

press esc then : wq!enter

Then you need to give the file the right permissions and set it to load on startup.

sudo chown root:wheel /Library/LaunchDaemons/com.mysql.mysql.plist 
sudo chmod 644 /Library/LaunchDaemons/com.mysql.mysql.plist 
sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysql.plist

And that is it.
