如何将Scaleway上的SHOUTcast服务器重定向到子域名？

Hey there, let's get your SHOUTcast service accessible via a clean subdomain (like radio.myserv.com) instead of typing the port number every time. Here's a step-by-step guide tailored to your setup:

1. Add a Subdomain DNS Record #

First, you need to point your desired subdomain to your Scaleway server IP:

• Log into your HE.NET DNS management panel
• Create a new A Record with:
  • Hostname: Your preferred subdomain (e.g., radio)
  • Target: 1.2.3.4 (your server's IP)
• Save the record and wait for DNS propagation (this can take 5-30 minutes, sometimes longer depending on TTL settings)

2. Set Up a Reverse Proxy with Nginx #

The easiest way to map the subdomain to your SHOUTcast port is using a reverse proxy. We'll use Nginx here (it's lightweight and widely supported):

Install Nginx (if not already installed) #

Run these commands based on your Linux distro:

• For Debian/Ubuntu:

  sudo apt update && sudo apt install nginx -y
  

• For RHEL/CentOS/Fedora:

  sudo dnf install nginx -y
  

Create a Custom Nginx Configuration File #

Create a new config file for your subdomain:

sudo nano /etc/nginx/sites-available/radio.myserv.com

Paste this configuration (replace radio.myserv.com with your actual subdomain):

server {
    listen 80;
    server_name radio.myserv.com;

    location / {
        # Proxy requests to your SHOUTcast service on port 8000
        proxy_pass http://127.0.0.1:8000;
        
        # Pass necessary headers to SHOUTcast
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        
        # Disable buffering to support smooth streaming
        proxy_buffering off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Enable the Configuration and Restart Nginx #

• Link the config file to the enabled sites directory:

  sudo ln -s /etc/nginx/sites-available/radio.myserv.com /etc/nginx/sites-enabled/
  

• Test the Nginx configuration for syntax errors:

  sudo nginx -t
  

• If you see "test is successful", restart Nginx to apply changes:

  sudo systemctl restart nginx
  

3. Update SHOUTcast Configuration (Critical!) #

SHOUTcast might block proxy requests by default, so adjust its settings:

• Open your SHOUTcast config file (usually sc_serv.conf in your SHOUTcast directory)
• Find the AllowRelay setting and set it to:

  AllowRelay=Yes
  

• Save the file and restart your SHOUTcast service to apply changes.

4. (Optional) Add HTTPS for a Secure Connection #

If you want your subdomain to use https:// instead of http://, use Certbot to get a free SSL certificate:

• Install Certbot and the Nginx plugin:

  sudo apt install certbot python3-certbot-nginx -y  # Debian/Ubuntu
  # OR
  sudo dnf install certbot python3-certbot-nginx -y  # RHEL/CentOS/Fedora
  

• Run Certbot to configure SSL automatically:

  sudo certbot --nginx -d radio.myserv.com
  

Follow the on-screen prompts, and Certbot will update your Nginx config to use HTTPS and set up auto-renewal for the certificate.

Verify the Setup #

Once DNS propagation is complete, open your browser and visit http://radio.myserv.com (or https:// if you set up SSL). You should see your SHOUTcast service without needing to append the :8000 port.
