What setting can open access to editing on the server?

Question

PHP

It turns out that during installation it always went smoothly, but something like this popped up on the new VDS: prntscr.com/8qnqto what could this mean? What setting is not configured?
PS I can read what is written there and it is difficult for me to create a file, blah blah blah. I am interested in the solution ONLY in the web server settings, so that this does not happen, I know it lies there!) If some information is not enough - write what needs to be added - I will indicate.

Answer 1

I guess that you are using apache with mpm-prefork, which runs as the user www-data/httpd/nobody, and the files are uploaded via FTP under another user with rights 644 (755 for directories), respectively, php, launched from under apache, is not can write in them.
If there is only one site on the vps, then you can change the User and Group parameters in the apache config to your user, but some phpmyadmin installed through the package manager of your distribution may fall off.
Well, or change the rights, as advised above.
