Nginx (pronounced the same as engine x) is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server, and is released under a BSD-like protocol.
was developed by Russian programmer Igor Sysoev and was originally used by Rambler (Russian: Рамблер), a large Russian portal website and search engine. Its characteristics are that it occupies less memory and has strong concurrency capabilities. In fact, nginx's concurrency capabilities do perform better among web servers of the same type.

NGINX can be used to improve website performance, security, and scalability. 1) As a reverse proxy and load balancer, NGINX can optimize back-end services and share traffic. 2) Through event-driven and asynchronous architecture, NGINX efficiently handles high concurrent connections. 3) Configuration files allow flexible definition of rules, such as static file service and load balancing. 4) Optimization suggestions include enabling Gzip compression, using cache and tuning the worker process.

NGINXUnit supports multiple programming languages and is implemented through modular design. 1. Loading language module: Load the corresponding module according to the configuration file. 2. Application startup: Execute application code when the calling language runs. 3. Request processing: forward the request to the application instance. 4. Response return: Return the processed response to the client.

NGINX and Apache have their own advantages and disadvantages and are suitable for different scenarios. 1.NGINX is suitable for high concurrency and low resource consumption scenarios. 2. Apache is suitable for scenarios where complex configurations and rich modules are required. By comparing their core features, performance differences, and best practices, you can help you choose the server software that best suits your needs.

Question: How to start Nginx? Answer: Install Nginx Startup Nginx Verification Nginx Is Nginx Started Explore other startup options Automatically start Nginx

How to confirm whether Nginx is started: 1. Use the command line: systemctl status nginx (Linux/Unix), netstat -ano | findstr 80 (Windows); 2. Check whether port 80 is open; 3. Check the Nginx startup message in the system log; 4. Use third-party tools, such as Nagios, Zabbix, and Icinga.

To shut down the Nginx service, follow these steps: Determine the installation type: Red Hat/CentOS (systemctl status nginx) or Debian/Ubuntu (service nginx status) Stop the service: Red Hat/CentOS (systemctl stop nginx) or Debian/Ubuntu (service nginx stop) Disable automatic startup (optional): Red Hat/CentOS (systemctl disabled nginx) or Debian/Ubuntu (syst

How to configure Nginx in Windows? Install Nginx and create a virtual host configuration. Modify the main configuration file and include the virtual host configuration. Start or reload Nginx. Test the configuration and view the website. Selectively enable SSL and configure SSL certificates. Selectively set the firewall to allow port 80 and 443 traffic.

The server does not have permission to access the requested resource, resulting in a nginx 403 error. Solutions include: Check file permissions. Check the .htaccess configuration. Check nginx configuration. Configure SELinux permissions. Check the firewall rules. Troubleshoot other causes such as browser problems, server failures, or other possible errors.
