I started with one server running Apache, PHP, MySQL. Now I have split off my web server so I am running all the PHP files on one server and my MySQL is still on the original server. Are there services / programs that I can turn off or uninstall from the MySQL Server now, or do I need to keep httpd (etc) running? I know how to turn it off, I need to know if it is okay to turn it off without breaking anything.
I am using Amazon AWS and connecting from the PHP server to the MySQL database using the MySQL Database's Internal DNS / IP Address.
I am using Amazon Linux AMI release 2012.09
Thank you for any insight you can provide.
