How Tengine Web Server Works

Tengine, like Nginx, operates based on an event-driven, asynchronous, and non-blocking architecture. This means it can handle multiple connections concurrently without creating a new process or thread for each new request, unlike traditional web servers. Instead, it uses a small number of worker processes to handle all requests. This architecture allows Tengine to provide high performance and scalability, even under heavy loads.

When a request comes in, Tengine first determines the type of request (HTTP, HTTPS, etc.) and then processes it accordingly. It uses a modular approach, with different modules handling different aspects of the request, such as parsing HTTP headers, processing PHP scripts, or serving static files.

Architecture of Tengine

The architecture of Tengine is similar to that of Nginx, with some enhancements. It consists of a master process and several worker processes. The master process is responsible for managing the worker processes, while the worker processes handle the actual requests.

Tengine’s architecture also includes several key components, such as event modules, phase handlers, and output filters. Event modules handle events like reading or writing to a network socket. Phase handlers process the different stages of a request, and output filters transform the response before it’s sent to the client.
