What is nginx configuration

nginx configuration is the main configuration file, virtual host configuration, HTTP request processing, reverse proxy, load balancing, static file processing, HTTP compression, SSL/TLS support, virtual host configuration and log files.

Nginx (pronounced "engine-x") is a lightweight open source web server software that can also be used as a reverse proxy server and load balancing server and HTTP cache server. Nginx is developed by Russian programmer Igor Sysoev was developed in 2004 to solve the C10k problem (i.e. how to handle 10,000 concurrent connections).

Nginx configuration refers to the process of setting up and adjusting the behavior and functions of the Nginx server. Through configuration files, you can define functions such as virtual hosts, HTTP request processing, reverse proxy, caching, and load balancing. Nginx's configuration syntax is concise and powerful, allowing administrators to make flexible adjustments according to their own needs.

The following will introduce some important aspects and common instructions of Nginx configuration:

1. Main configuration file (nginx.conf): The configuration file of the Nginx server is an important entry point. It contains global configuration directives and introduces other configuration files.

2. Virtual host configuration: Nginx supports multiple virtual hosts. Each virtual host can have its own domain name, listening port, log file and other configurations. By configuring a virtual host, you can serve multiple websites or applications at the same time.

3. HTTP request handling: One of the core functions of Nginx is handling HTTP requests. Nginx can be configured to send requests to a specific server block or reverse proxy server based on the requested URL or other criteria.

4. Reverse proxy: Nginx can be used as a reverse proxy server to forward received client requests to the back-end application server. This is useful for load balancing, caching and security needs.

5. Load balancing: Nginx supports a variety of load balancing algorithms, such as polling, weight, IP hashing, etc. By distributing requests to multiple backend servers, you can improve the performance and reliability of your system.

6. Static file processing: Nginx can efficiently process static files, such as HTML, CSS, JavaScript, images, etc. Performance can be further optimized by configuring the cache time and compression parameters of static files.

7. HTTP compression: Nginx supports compression of HTTP responses to improve page loading speed by reducing the size of transmitted files.

8. SSL/TLS support: Nginx can be configured with an HTTPS server to provide secure encrypted communication. Web applications can be secured by configuring SSL certificates and cipher suites.

9. Virtual host configuration: Nginx's configuration file uses a unique syntax structure, which uses blocks and directives to make the configuration more concise and readable.

10. Log files: Nginx can write access logs and error logs to files to facilitate understanding of the server's operating status and troubleshooting.

In short, Nginx configuration is a very important and flexible process. Through appropriate configuration and adjustment, server performance can be optimized, security improved and maintenance easier. Mastering Nginx configuration skills can help system administrators better manage the web server and ensure its normal operation and high-quality services. .
