Im kinda new to vps stuff but not super new. Ive had some for a while, I can install things and stuff but want to learn more. I dont want to use a control panel. What things should I install to keep things fast and secure for a website that needs php and MySQL? I was thinking of using nginx, mysql, php, and installing CSF. I know to change the ssh port and ssh user too. What other things could I do to keep things fast and secure? I have a 2GB VPS so I have plenty of RAM to run things. Thanks.
