AWS EC2中Django runserver 8000端口域名访问异常问题咨询

Hey there! Let's get your site working without needing to append :8000 to your domain. Here are the most practical solutions tailored to your AWS EC2 setup:

1. Use Nginx as Reverse Proxy (Recommended for Production) #

This is the go-to method for production environments—it's stable, secure, and handles traffic efficiently.

• Install Nginx
  On Ubuntu/Debian:

  sudo apt update && sudo apt install nginx
  

  On Amazon Linux/CentOS:

  sudo yum install nginx
  

• Start and enable Nginx

  sudo systemctl start nginx
  sudo systemctl enable nginx
  

• Configure reverse proxy

  1. Back up the default config first:

     sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/default.bak
     

  2. Edit the config file:

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

  3. Replace the default server block with this (replace your-domain.com with your actual domain):

     server {
         listen 80;
         server_name your-domain.com;
     
         location / {
             proxy_pass http://127.0.0.1:8000;
             proxy_set_header Host $host;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Forwarded-Proto $scheme;
         }
     }
     

  4. Check if the config is valid:

     sudo nginx -t
     

  5. Restart Nginx to apply changes:

     sudo systemctl restart nginx
     

• Update EC2 Security Group
  Add an inbound rule allowing traffic on port 80 (TCP, from 0.0.0.0/0 or your desired source).

2. Port Forwarding with iptables (Quick Temporary Fix) #

If you need a quick workaround for testing (not recommended for production), use iptables to forward port 80 traffic to 8000:

• Run this command to set up forwarding:

  sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8000
  

• Save the rule so it persists after reboot:

  • Ubuntu/Debian: Install iptables-persistent and follow prompts to save rules:

    sudo apt install iptables-persistent
    

  • Amazon Linux/CentOS:

    sudo service iptables save
    

• Don't forget to open port 80 in your EC2 Security Group.

3. Run Django Directly on Port 80 (Not Recommended for Production) #

Django's built-in runserver is meant for development only—it's not optimized for performance or security. But if you're just testing:

• Run the server with root privileges (since port 80 is a privileged port):

  sudo python manage.py runserver 0.0.0.0:80
  

• Again, ensure port 80 is open in your EC2 Security Group.

Important Notes #

• Double-check that your domain is correctly pointed to your EC2 instance's public IP or Elastic IP.
• If you're using a CDN like Cloudflare, make sure it's configured to pass traffic to port 80 on your EC2 instance.
• For long-term production use, pair Nginx with a production-grade WSGI server like Gunicorn or uWSGI instead of relying on Django's runserver.
