# Run Locally After building: 1. Start the application on the VPS 2. Find the correct port and IP 3. Tell user: "做好了！打开这个网址看看效果：http://你的IP:端口" 4. If it doesn't load, check firewall, port conflicts, process errors For web apps, make sure: - The server binds to 0.0.0.0, not just localhost - The port is open in firewall (iptables) - The process stays running (use nohup or screen) Tell user: "你的产品在运行了。打开浏览器试试，有问题截图给我。"
