How Can I Configure Nginx to Serve Subfolders Differently?

Nginx Location Configuration for Subfolders

In Nginx configuration, managing access to subdirectories is crucial for organizing website content effectively. Let's consider a scenario where you have two subfolders, "/static" and "/manage," within a web root directory.

Problem:

You need to configure Nginx to provide access to these subfolders as follows:

• "/static" folder accessible at the root URI (e.g., http://example.org/)
• "/manage" folder accessible at "/manage" (e.g., http://example.org/manage)

Solution:

To address this issue, you need to utilize the alias directive for the "/manage" subfolder:

server {
    # ... (unchanged configuration)
    
    location ^~ /manage {
        alias /var/www/mysite/manage/public;
        index index.php;
        
        if (!-e $request_filename) { rewrite ^ /manage/index.php last; }
        
        location ~ \.php$ {
            if (!-f $request_filename) { return 404; }
            fastcgi_pass 127.0.0.1:9000;
            
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        }
    }
}

Alternative Solution Using Root:

In some cases, you may consider using the root directive instead of alias. However, it requires a nested location block and is generally less efficient for subfolder handling.

Additional Notes:

• The ^~ modifier ensures that the prefix location takes precedence over regular expression locations.
• The try_files and alias directives cannot be used together due to a known bug.
• The if directive should be handled with caution to avoid unexpected behaviors.
