Nginx and uWISG are two commonly used server software that can work together to provide more stable and efficient network services. This article will introduce in detail the working principle of the cooperation between Nginx and uWISG, and how to configure them to achieve optimal performance.

1. Characteristics of Nginx server

Nginx is a high-performance web server software that uses an event-driven asynchronous I/O model and can handle a large number of concurrent requests. The features of Nginx include the following aspects:

1. High concurrent processing capability: Nginx uses an asynchronous I/O model and can handle tens of thousands of concurrent requests at the same time, which is very suitable for high-concurrency Web applications.
2. Load balancing function: Nginx can be used as a reverse proxy server to implement load balancing function, distribute requests to multiple backend servers, and improve system reliability and performance.
3. Static resource caching: Nginx can cache static resources, such as images, CSS, JS, etc., to reduce the pressure on the backend server and improve access speed.
4. Support HTTP/2 protocol: Nginx supports HTTP/2 protocol, which can transmit data more efficiently and improve the response speed of the website.

2. Features of uWISG Server

uWISG is a lightweight Web server software that uses CGI to process dynamic requests and can support multiple programming languages, such as PHP, Python, Ruby, etc. The features of uWISG include the following aspects:

1. Support multiple programming languages: uWISG can support multiple programming languages ​​to meet different development needs.
2. Lightweight: uWISG is a lightweight Web server software that takes up less resources and is suitable for low-configuration servers.
3. High security: uWISG adopts a variety of security mechanisms, such as Sandbox isolation and permission control, which can effectively prevent the occurrence of security vulnerabilities.

3. Working principle of Nginx and uWISG

Nginx and uWISG can work together to provide more stable and efficient network services. The specific working principle is as follows:

1. Nginx as a reverse proxy server: Nginx can be used as a reverse proxy server to distribute requests to multiple backend uWISG servers. This can achieve load balancing and improve system reliability and performance.
2. Nginx caches static resources: Nginx can cache static resources, such as images, CSS, JS, etc., to reduce the pressure on the backend uWISG server and improve access speed.
3. uWISG processes dynamic requests: uWISG can process dynamic requests, such as requests from scripting languages ​​such as PHP, Python, and Ruby. uWISG can be used in conjunction with Nginx to achieve separation of high-concurrency processing and dynamic request processing.
4. Nginx is responsible for HTTPS protocol encryption: Nginx can be responsible for the encryption and decryption of the HTTPS protocol to ensure the security of data transmission.

4. Configuration methods of Nginx and uWISG

The configuration methods of Nginx and uWISG are as follows:

1. Configure Nginx reverse proxy: Add reverse proxy configuration in the Nginx configuration file to distribute requests to multiple uWISG servers.
2. Configure Nginx to cache static resources: Add the configuration of caching static resources in the Nginx configuration file, cache static resources in Nginx, and reduce the pressure on the uWISG server.
3. Configure uWISG: Set the CGI path, programming language and other information in the uWISG configuration file to support dynamic request processing.
4. Configure HTTPS protocol: Add HTTPS protocol configuration in the Nginx configuration file to implement encryption and decryption of data transmission.

5. Notes

When working with Nginx and uWISG, you need to pay attention to the following issues:

1. Load balancing strategy: When configuring Nginx reverse proxy, you need to choose an appropriate load balancing strategy, such as polling, IP hashing, etc., to achieve optimal performance.
2. Static resource cache time: When configuring Nginx to cache static resources, you need to set the cache time reasonably to avoid performance being affected by too long or too short cache time.
3. CGI path setting: When configuring uWISG, you need to set the correct CGI path to ensure that dynamic requests can be processed correctly.
4. HTTPS certificate settings: When configuring the HTTPS protocol of Nginx, you need to set the correct certificate and private key to ensure the security of data transmission.

Summarize

Nginx and uWISG can work together to provide more stable and efficient network services. When configuring Nginx and uWISG, you need to pay attention to issues such as load balancing strategy, static resource cache time, CGI path settings, and HTTPS certificate settings to achieve optimal performance.
