Настройка Nginx

Подробно как установить Nginx описано на официальном сайте.
Для настройки вам также понадобиться домен и доступ к нему. Вам нужно будет создать A запись, вида launcher.ВАШ_ДОМЕН.ru.
Вам нужно будет скопировать конфигурацию описанную ниже по пути /etc/nginx/conf.d/launcher.ВАШ_ДОМЕН.conf. При отсутствии доменного имени настроить файл необходимо немного иначе, конфигурация прилагается.

http

upstream ws-launcher {
    server 127.0.0.1:1370;
}
map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}
server {
    listen 80;
    server_name launcher.ВАШ_ДОМЕН;
    charset utf-8;
    #access_log  /var/log/nginx/launcher.ВАШ_ДОМЕН.access.log;
    #error_log  /var/log/nginx/launcher.ВАШ_ДОМЕН.error.log notice;
    client_max_body_size 100M;


    location /files {
        alias ПУТЬ/ДО/ПАПКИ/gameFiles;
        autoindex on;
    }
    location / {
        proxy_pass http://ws-launcher;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
