The nginx stream module is a core module of nginx, designed to support proxy, load balancing, and traffic forwarding for TCP and UDP traffic.

It has several main uses:

  1. TCP proxy: can forward TCP traffic from clients to multiple backend servers, used for load balancing, high availability, and fault tolerance functions.
  2. UDP proxy: can forward UDP traffic from clients to multiple servers in the backend. It can be used to achieve load balancing, high availability, and fault recovery functions.
  3. SSL/TLS terminal proxy: This can establish secure SSL/TLS connections between client and backend servers, enhancing the security of transmitting sensitive information.
  4. SOCKS proxy: can forward TCP or UDP traffic from the client to multiple backend servers, supporting SOCKS4, SOCKS4a, and SOCKS5 protocols.
  5. Forwarding configuration: allows configuration requests coming from the client to be forwarded to multiple backend servers, useful for configuration management and dynamic configuration updates.

By configuring nginx’s stream module, the above functionality can be achieved with high performance and reliability.
