Nginx на VDSina

Установка и настройка Nginx в качестве reverse-proxy для Node.js-приложений на VPS VDSina.

1. Установка

sudo apt update
sudo apt install nginx

2. Автозапуск и проверка

# Добавить в автозапуск
sudo systemctl enable nginx

# Проверить статус
sudo service nginx status

# Проверить автозапуск
sudo systemctl is-enabled nginx

Строка Active: active (running) подтверждает успешную работу.

3. Конфигурационные файлы

4. Конфигурация reverse-proxy для Node.js

Файл: /etc/nginx/sites-enabled/example.conf

Nginx проксирует /api → Node.js на порту 3000, /bot → Node.js на порту 3010.

upstream api {
    server localhost:3000;
}
upstream bot {
    server localhost:3010;
}

server {
    server_name example.com;

    root /var/www/html;
    index index.html index.htm;
    error_page 404 /404.html;

    location / {
        try_files $uri $uri/ =404;
    }

    location /api {
        proxy_pass http://api;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    location /bot {
        proxy_pass http://bot;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}

server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    }

    listen 80;
    server_name example.com;
    return 404;
