Changing Apache MPM from Worker to Prefork [SOLVED]

[hakeryk]

Hey,

Probably during installation, I set Apache MPM Worker for Event but I intended Prefork yet I am kind of scared to change something at the production server now. All my websites are using alternative PHP 7.4-FPM as an extra PHP Interpreter and there is 8.2 for Keyhelp as well.

As I mentioned before this is a live server and I don't have a spare development server to test it so can You confirm that the method used here: https://serverfault.com/a/1050801/440487 (pic below as well) will be ok?



I am aware that it might be easy as it is but when something goes wrong then I am dead on arrival so if someone can confirm that the above method will work I will be very happy because I don't have to set up another testing machine just to do this.

Or maybe there is a built-in method that I simply can't find?

Have a great weekend!

Don't change it manually. It will break everything.
Just change the field Settings / Configuration / Web Server / Multi-processing module (MPN) in Keyhelp.

I changed it in the past without any trouble.
The Apache will restart though.

Oh, there it is! Ok, gonna give it a try and later comeback with the results. Thank You!

I cannot edit my previous post because it was "SOLVED" but all I want is just to confirm that the method using a panel is working correctly and I didn't even have to restart apache service.



Thanks!
