Nginx virtual hosts guide: because juggling multiple sites on one server beats paying for actual cloud scaling, right?

Nginx, a popular web server software, allows users to host multiple websites on a single server using virtual hosts, also known as server blocks. This feature enables website owners to manage multiple projects on one server, each with its own configuration and logs. To set up virtual hosts, users need to create a server block configuration file, specifying the server name, root directory, and log files. The correct structure of directories is crucial, with a recommended approach of using a public directory for website files and a separate logs directory. Nginx uses the HTTP Host header to determine which server block to apply, and a default server block can be set up to protect against unwanted requests. Proper configuration and logging are essential for security and troubleshooting. By following best practices, users can ensure a scalable and secure web server setup, with separate logs and configurations for each website, making it easier to manage and maintain multiple projects on a single server.
