Internal Server error 500 when connecting mod_fcgid on Apache CentOS 7?

Question

linux

There is a server on VirtualBox on CentOS 7. A bunch of Nginx + Apache (where nginx is the frontend, and Apache is the backend).
Because with dynamics, apache works for me, I understand that I need to connect fastcgi to it.
It costs PHP 7. It's just that sites work in mod_php mode.
1. Connected mod_fcgid module (required LoadModule is in httpd.conf)
2. Contents in fcgid.conf:

# This is the Apache server configuration file for providing FastCGI support
# through mod_fcgid
#
# Documentation is available at
# http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html

# Use FastCGI to process .fcg .fcgi & .fpl scripts
AddHandler fcgid-script fcg fcgi fpl

# Sane place to put sockets and shared memory file
FcgidIPCDir /run/mod_fcgid
FcgidProcessTableFile /run/mod_fcgid/fcgid_shm

DirectoryIndex index.php

FcgidFixPathinfo 1
FcgidMaxRequestsPerProcess 10000

3. Uncommented in php.ini:
cgi.fix_pathinfo=1
4. Created /var/www/php-cgi directory (sites are in /var/www/daniel/site1.ru/public_html....). It contains a php.fcgi file with the following content:

#!/bin/sh
PHP_FCGI_MAX_REQUESTS=10000
export PHP_FCGI_MAX_REQUESTS
exec /usr/bin/php-cgi

5. The site2.ru.conf file contains:

<VirtualHost *:8080>
ServerName site2.ru
ServerAlias www.site2.ru
DocumentRoot /var/www/daniel/site2.ru/public_html
ErrorLog /var/log/httpd/site2_ru_error.log
CustomLog /var/log/httpd/site2_ru_requests.log combined
SuexecUserGroup daniel daniel

<IfModule mod_fcgid.c>
FcgidBusyTimeout 3600
</IfModule>

<Directory "/var/www/daniel/site2.ru/public_html">
Options +ExecCGI
AddHandler fcgid-script .php
FcgiWrapper /var/www/php-cgi/php.fcgi .php
AllowOverride All
Order allow,deny
Allow from all
</Directory>

</VirtualHost>

6. I have the following permissions: apache runs under daniel:daniel and the entire /var/www/ directory recursively too.
The directories /var/www/php-cgi generally gave 777 in the end, because I googled what happens because of these rights an error.
At first I had an error with Permissions, I put the user daniel:daniel in /run/mod_fcgid/ and gave permissions 755.
The error with permissions disappeared, but now the main error has appeared, on which I am stuck.
When I go to the site, I have Internal Server Error 500. I
found errors only in the logs /var/log/httpd/site2_ru_error.log.

[Wed May 08 01:47:21.480618 2019] [fcgid:warn] [pid 32082] (104)Connection reset by peer: [client 127.0.0.1:52274] mod_fcgid: error reading data from FastCGI server

In php.ini and in fcgid.conf I tried to increase the amount of memory and the timeout. In vain.
Need help!
