Why is it impossible to raise a symphony site on VDS with Debian+Vesta+nginx+php-fpm?

Question

PHP

I went into a dead corner, I just can’t transfer the symphony3 project to the server
, I tried different configurations, I run into an error 500 that is not logged
and I don’t know where to move next
, could you tell me how to set up the ngnix configs so that it’s cursed all the same, it’s earned
Dano:
VPS on the digital ocean (bare system)
I install Vestacp (nginx + php-fpm) with their installer
, as a result I get a working server with this config

server {
    listen      хх.хх.186.154:80;
    server_name мойдомен.com www.tмойдомен.com;
    root        /home/admin/web/мойдомен.com/public_html;
    index       index.php index.html index.htm;
    error_log   /var/log/nginx/domains/мойдомен.com.error.log error;

    location / {

        location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|css|js)$ {
            expires     max;
        }

        location ~ [^/]\.php(/|$) {
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            if (!-f $document_root$fastcgi_script_name) {
                return  404;
            }

            fastcgi_pass    127.0.0.1:9001;
            fastcgi_index   index.php;
            include         /etc/nginx/fastcgi_params;
        }
    }

    error_page  403 /error/404.html;
    error_page  404 /error/404.html;
    error_page  500 502 503 504 /error/50x.html;

    location /error/ {
        alias   /home/admin/web/мойдомен/document_errors/;
    }

    location ~* "/\.(htaccess|htpasswd)$" {
        deny    all;
        return  404;
    }

    location /vstats/ {
        alias   /home/admin/web/мойдомен.com/stats/;
        include /home/admin/web/мойдомен.com/stats/auth.conf*;
    }

    include     /etc/nginx/conf.d/phpmyadmin.inc*;
    include     /etc/nginx/conf.d/phppgadmin.inc*;
    include     /etc/nginx/conf.d/webmail.inc*;

    include     /home/admin/conf/web/nginx.мойдомен.com.conf*;
}

the folder structure is /home/admin# find . -print

I throw the project files in public_html (in general, the site will work on https, here the question will also arise later) I prescribe root /home/admin/web/mydomain.com/public_html/web
in the nginx config ; index app.php index.php index.html index.htm; location / { try_files $uri /app.php$is_args$args; } and I get a 500 error that is not logged, can you help with the nginx config please :)

Answer 1

500 error is a php error, it should be logged in any case, look here
/var/log/nginx/domains/mydomain.com.error.log
If it is empty, then enable the additional php-fpm log.
