Explanation

This Nginx configuration sets up a server block that listens on port 80 for requests to www.example.com and example.com. The root directory for the website is specified as /home/demo/sites/example.com/public_html, where the index files are located. The configuration also includes a location block for handling PHP files using PHP-FPM, which is set to communicate over 127.0.0.1:9000.

Common Issues

If you encounter a 403 Forbidden error, ensure that:

  • The Nginx user (www-data) has the necessary permissions to access the files in the specified root directory.
  • The directory and files have appropriate permissions set (e.g., 755 for directories and 644 for files).
  • The SELinux settings (if enabled) are configured to allow Nginx to access the files.

Permissions Example

To set the correct permissions, you can use the following commands:

chown -R www-data:www-data /home/demo/sites/example.com/public_html
chmod -R 755 /home/demo/sites/example.com/public_html
