Apache installation - what to choose?

Question

Apache HTTP Server

Hello
Which is better to install and why:
1) apache2-mpm-prefork
2) apache2-mpm-itk
Thanks

Answer 1

itk is based on prefork, allows each vhost to run as its own user (which allows you to isolate sites by file permissions). It does not allow using php in fcgi mode (is it necessary? There is nginx for this).
In short, you read the documentation. There are many useful things there.

Answer 2

Documentation on their website
