When entering the local domain, there is a redirect to localhost (nginx), how to fix it?

Question

Nginx

When I enter the local domain mysite.ru, instead of index.html, "Welcome to nginx!" opens, how can I fix it?
Below are the configs.
OS: Manjaro 18.1.3
Nginx 1.16.1
Configured nginx.conf:

#user html;
 
worker_processes  2;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;
 
events {
    worker_connections  1024;
}
 
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
 
    #tcp_nopush     on;
    #keepalive_timeout  0;
 
    keepalive_timeout  65;
 
    gzip  on;
 
    types_hash_max_size 4096;
 
    server {
        listen       80;
        server_name  localhost;
        server_name_in_redirect off;
  root   /usr/share/nginx/html;
        charset utf-8;
        location / {
            index  index.php index.html index.htm;
            autoindex on;
            autoindex_exact_size off;
            autoindex_localtime on;
        }
 
        location /phpmyadmin {
            rewrite ^/* /phpMyAdmin last;
        }
 
        error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
 
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
 
        location ~ \.php$ {
            #fastcgi_pass 127.0.0.1:9000; (зависит от конфигурации сокета вашего php-fpm)
            fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
            fastcgi_index index.php;
            include fastcgi.conf;
        }
 
        location ~ /\.ht {
            deny  all;
        }
    }         
}

The site directory contains an index.html file with simple markup, I will not attach it.
Also in /etc/hosts I wrote:

127.0.0.1 mysite.ru
127.0.0.1 www.mysite.ru

Answer 1

Created host, file /etc/nginx/sites-available/mysite.ru

he on yours should include itself in the main config?
