🟢 Nginx

Nginx is our recommended web server for Monitron SaaS. It's fast, lightweight, and handles many concurrent connections efficiently — perfect for a monitoring platform that makes frequent HTTP requests.

📋 前提条件​

  • Nginx 1.18+ installed
  • PHP-FPM installed and running
  • SSL certificate (we recommend Let's Encrypt)

📝 Configuration File​

Create a new Nginx server block:

sudo nano /etc/nginx/sites-available/monitron

Paste this configuration:

server {
    listen 80;
    server_name your-domain.com;

    # Redirect all HTTP to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name your-domain.com;

    # ─── SSL Configuration ───────────────────────────────────
    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384;
    ssl_prefer_server_ciphers off;

    # ─── Document Root ────────────────────────────────────────
    # 🚨 IMPORTANT: Point to the /public directory!
    root /var/www/monitron/public;
    index index.php;

    # ─── Character Encoding ───────────────────────────────────
    charset utf-8;

    # ─── Logging ──────────────────────────────────────────────
    access_log /var/log/nginx/monitron-access.log;
    error_log /var/log/nginx/monitron-error.log;

        include fastcgi_params;
        fastcgi_hide_header X-Powered-By;

        # Increase timeouts for long-running AI requests

    location ~ /\.(?!well-known).* {
        deny all;
    }

    # ─── Static File Caching ─────────────────────────────────
    location ~* \.(css|js|png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|eot)$ {

        add_header Cache-Control "public, immutable";
        try_files $uri =404;
    }

🔧 Step-by-Step Setup​

1. Replace Placeholders​

In the config above, replace:

占位符替换为
your-domain.comYour actual domain name
/var/www/monitronYour Monitron installation path
php8.3-fpm.sockYour PHP-FPM socket (check with ls /var/run/php/)
SSL certificate pathsYour actual certificate paths

2. Enable the Site​

# Create symbolic link to enable the site
sudo ln -s /etc/nginx/sites-available/monitron /etc/nginx/sites-enabled/

# Remove the default site if you don't need it
sudo rm /etc/nginx/sites-enabled/default

3. Test the Configuration​

sudo nginx -t

You should see:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

4. Restart Nginx​

sudo systemctl restart nginx

🔒 Setting Up SSL with Let's Encrypt​

If you don't have an SSL certificate yet, use Certbot:

# Install Certbot
sudo apt install certbot python3-certbot-nginx

# Obtain certificate (replaces the SSL config automatically)
sudo certbot --nginx -d your-domain.com

# Test auto-renewal
sudo certbot renew --dry-run

Certbot will automatically configure Nginx for SSL!

🐘 PHP-FPM Configuration​

For better performance with many monitors, tune PHP-FPM:

sudo nano /etc/php/8.3/fpm/pool.d/www.conf

Recommended settings:

; Process manager — dynamic is recommended
pm = dynamic
pm.max_children = 20
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 10
pm.max_requests = 1000

; Timeouts
request_terminate_timeout = 120

; For monitoring many services, increase memory limit
php_admin_value[memory_limit] = 256M

Restart PHP-FPM:

sudo systemctl restart php8.3-fpm

✅ 验证是否正常​

  1. Visit https://your-domain.com — you should be redirected to /install (first time) or /admin (after installation)
  2. Check that https://your-domain.com/.env returns a 403 or 404 (security!)
  3. Test a status page URL works: https://your-domain.com/status/test

🛠️ 故障排除​

502 Bad Gateway​

PHP-FPM isn't running or the socket path is wrong:

# Check if PHP-FPM is running
sudo systemctl status php8.3-fpm

# Find the correct socket path
ls /var/run/php/

# Restart PHP-FPM
sudo systemctl restart php8.3-fpm

403 Forbidden​

Usually a permissions issue:

sudo chown -R www-data:www-data /var/www/monitron
sudo chmod -R 755 /var/www/monitron
sudo chmod -R 775 /var/www/monitron/storage

Blank White Page​
