How to specify the configuration file path when starting nginx?

To specify the configuration file path for nginx, use the -c parameter when starting nginx.

Assuming your nginx configuration file is located at /etc/nginx/nginx.conf, you can start nginx and specify the configuration file path with the following command:

nginx -c /etc/nginx/nginx.conf

If you are using a Linux system, you need to use the sudo command to run that command with administrator privileges.

sudo nginx -c /etc/nginx/nginx.conf

Please ensure that the path is correct and that you have sufficient permission to access the files in that path.
