CentOS + Nginx + PHP - permissions problem - what could be the reason?

Question

CentOS

I am deploying a project on symphony, on CentOS.
I get the classic first run error:

The stream or file "/var/www/site.loc/var/log/dev.log" could not be opened: failed to open stream: Permission denied

Usually, locally on Ubuntu + nginx, this problem is solved simply: chmod -R 777 /var/www/site.loc/var/
and that's it. At the same time, the user:group parameters for everything in www from the local user: walk:walk
On CentOS, control comes from root, and all user:groups go to root:root. And a simple prescription of rights 777 does not help.
I looked at the nginx config, from which user the work is happening. This is nginx
Changed www user:group recursively to nginx:nginx - the problem still remains.
ll at the root of the project shows this:

What else can be done? Where to look for the cause of problems with rights?

Answer 1

Disable selinux and reboot.
Or write rules for selinux.

Answer 2

Why chop off the shoulder and turn it off?
The problem lies in SELinuxe and its useful security policy.
In short, you need to add the necessary context to the directory so that Nginx can write logs there - httpd_log_t. I wrote more about the
solution at i.valman.org/2020/10/nginx-centos-selinux.html words and one comment do not lay down the whole meaning of the actions.
