Implementing Multi-Subdomain Pointing to Different Ports on a Single-IP Server
This paper explores solutions for directing multiple subdomains to different ports on a single-IP server using DNS configuration and network technologies. It begins by analyzing the fundamental principles of DNS and its relationship with ports, highlighting that DNS resolves domain names to IP addresses without handling port information. Three main approaches are detailed: utilizing SRV records, configuring a reverse proxy server (e.g., Nginx), and assigning multiple IP addresses. Emphasis is placed on the reverse proxy method as the most practical and flexible solution for single-IP scenarios, enabling subdomain-to-port mapping. The paper provides concrete configuration examples and step-by-step instructions for deployment. Finally, it summarizes the pros and cons of each method and offers recommendations for applicable contexts.
