How to serve PHP files from a subdirectory of xgboost-ci.net

[hcho3]

I've set up a website from a subdirectory of xgboost-ci.net: https://xgboost-ci.net/dashboard/. In #6, we chose Nginx for the web server, so we modify the Nginx configuration here.

1. Create the directory /var/www/xgboost-ci.net/html/dashboard.
2. Create the file index.php in /var/www/xgboost-ci.net/html/dashboard with the following content:

   <?php phpinfo(); ?>

3. Since Nginx doesn't contain native PHP processing like Apache, we install the FastCGI PHP bridge by running sudo apt install php7.2-fpm php7.2-mbstring php7.2-xml php-pear.
4. Open the configuration file /etc/nginx/sites-enabled/xgboost-ci.net. Add the following configuration block to the server block:

   location ^~ /dashboard {
   alias /var/www/xgboost-ci.net/html/dashboard;
   try_files $uri $uri/ =404;
   location ~ \.php$ {
       include snippets/fastcgi-php.conf;
       fastcgi_param SCRIPT_FILENAME $request_filename;
       fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
   }
   }

   Also, change the line index index.html index.htm; to index index.html index.htm index.php;.

5. Run sudo nginx -t to verify the modified configuration.
6. Restart Nginx to apply the new configuration: sudo systemctl reload nginx.
7. Verify that https://xgboost-ci.net loads the Jenkins website and that https://xgboost-ci.net/dashboard/ loads the index.php we created earlier.
