Ubuntu 18.04 下配置 Nginx 路径别名（alias）

记录一下：

server {
  listen 443 ssl;
  listen [::]:443 ssl;
	server_name example.com www.example.com;

    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;
	index index.php index.html index.htm index.nginx-debian.html;

    location / {
	  root /var/www/example_com/public/_site;

      location ~ \.php$ {
	  	fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
	  	include snippets/fastcgi-php.conf;
              fastcgi_param SCRIPT_FILENAME $request_filename;
      }
    }

    location /en_edu {
        alias /var/www/en_edu;

        location ~ \.php$ {
	  	fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
	  	include snippets/fastcgi-php.conf;
               fastcgi_param SCRIPT_FILENAME $request_filename;
        }
    }

    location ~ /\.ht {
      deny all;
    }
}
