I'm trying to squeeze out just a bit more performance and I know that FastCGI is a bit faster. So how do I go about setting up FastCGI for PHP 7.4? I'm running a forum software (PHP script). Most of the articles I find on the internet and here do not cover the newest PHP 7.4 and typically the article states a directory that doesn't exist. I'm using cPanel/WHM 92.0.7.
Hey there! You may want to review these documentation pages if you're going to further tweak the system for improved performance:
docs.cpanel.net
Let me know if that clears things up!
PHP FastCGI Process Manager - PHP-FPM | cPanel & WHM Documentation
PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle high loads.
docs.cpanel.net
Let me know if that clears things up!
No. It didn't. I can flip on the FastCGI in the PHP controls but still run in CGI mode. So how do you configure the Fast CGI to be used because so far I've never found a way. It continues to show ZERO FastCGI proecesses. There is configuration in a file or something that has to be set up.
mod_fcgid status:
Total FastCGI processes: 0
mod_fcgid status:
Total FastCGI processes: 0
Thanks for the additional details. Can you let me know specifically where you are checking the total process numbers on your system?
Under WHM go to Server Status got to Apache Status. Then at the bottom of the page is mod_fcgid status: Total FastCGI processes: 0
Under WHM go to MultiPHP Manager I've got PHP 7.4 running with the PHP handler set to fcgi.
Under PHP Info if you look at $_SERVER['GATEWAY_INTERFACE'] it reports back only CGI/1.1
As far as I can find FastCGI is not running. I never see process move off ZERO even with Apache Benchmark running 2,000 connections in batches of 200.

Thanks for the clear details :D
I changed the PHP handler for one of my versions to fcgi, and confirmed there is a domain using that version of PHP. I checked a PHP info page on that domain and it did list fcgi as the process:
so I'm wondering if the handler isn't properly switching for that version of PHP since you're not even getting to that point.
In my WHM >> Apache Status page I see the numbers instantly increased for the CGI processes as I navigated the site.
Do you see any errors in the /etc/apache2/logs/error_log or /usr/local/cpanel/logs/error_log files when you make the switch to the fcgi handler in WHM? It seems like that is the most likely spot where there is a failure. If not, it might be best to submit a ticket so we can do some testing directly on that machine.

No. Always ZERO process. Then Server API like your only shows CGI/1.1...

This is what I found in the logs (snip).

In my hunting I found the listen string misconfigured... It's missing the address and port in the folder -
/opt/cpanel/ea-php74/root/etc/php-fpm.d
listen = /opt/cpanel/ea-php74/root/usr/var/run/php-fpm/xxxx.sock
So how do I figure out the listening port and address?
From PHP.net - Valid syntaxes are: 'ip.add.re.ss:port', 'port', '/path/to/unix/socket'.
/opt/cpanel/ea-php74/root/etc/php-fpm.d
listen = /opt/cpanel/ea-php74/root/usr/var/run/php-fpm/xxxx.sock

Ok. after playing for a bit I managed to crash the site. So I was close to having it but no sure of the port and address. The Apache side need the info (port and address) and the PHP-FPM pool. There is for sure a disconnect between the two and not passing info.
That's what I was getting at when I mentioned that something wasn't being configured properly. You shouldn't need to do anything with those files, or even know they exist, in order for things to just work.
For this issue it would be best to submit a ticket so we can see what's up and possibly prevent this in the future. If you do submit a ticket, please post the number here so I can follow along and keep the community updated as well.

Ummm... I need to contact Liquid Web first I guess after doing the support ticket...

You can do that directly from the WHM >> Create a Support Ticket interface. Just post the number here once you've done that!
