Tuning the Nginx Configuration

Adjust Nginx parameters to improve the Nginx performance.

The default Nginx configuration file is nginx.conf, which is located in the Nginx installation directory by default. The following is an example of an optimized Nginx configuration file.

The example configuration file is for reference only. In actual situations, adjust the configuration file based on your actual hardware environment and service requirements.
