php-fpm-on-cpanel-whm.md

• Killer feature of cPanel/WHM is multi-php.
• Mainly because multi-php allows you to enable php-fpm with a single UI toggle.
• Switching on php-fpm is basically zero-config in cPanel — enable it and the web server just starts using php-fpm.
• (still not sure what goes on under the hood, which is a bit concerning, but i'm taking whatever i can get)
• For comparison, setting this up without cPanel requires:
  • setting up apache to serve php application to php-fpm endpoint at :9000
  • setting up a reverse proxy that hits the php-fpm endpoint at :9000 and serves the processed content to :80 and :443
  • so we need install and configure: php-fpm, webserver1 that serves the php-fpm endpoint, webserver2 that reverse-proxies requests from :80 and :443 to webserver1:9000.
• currently tracking performance improvements, but am optimistic.
