How to log nginx errors to a file?

To log Nginx errors to a file, you can follow these steps:

1. Open the Nginx configuration file:

sudo nano /etc/nginx/nginx.conf

1. Add or modify the error_log directive to specify the path and filename for the error log file:

error_log /var/log/nginx/error.log;

Replace “/var/log/nginx/error.log” with the desired path and filename for the error log file.
3. Save and close the file.
4. Reload the Nginx configuration for the changes to take effect:

sudo service nginx reload

The error log file will now contain information about any errors that occur in Nginx, which can be helpful for troubleshooting issues with your website or server.
