nginx,同一域名，同一端口下配置多个项目，那么php连接应该怎么配置两个？
这里定义了两个站点

        location /discuz {
            alias       /usr/local/nginx/html/discuz/upload;
            index       index.php;
        }


        location /wordpress {
                alias   /usr/local/nginx/html/wordpress;
                index   index.php;
        }

求php的配置方法
下面应该怎么改

        location ~ /discuz/*\.php$ {
               root           /data/html/discuz;
               fastcgi_pass   192.168.1.25:9000;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
        }


        location ~ /wordpress/*\.php$ {
               root           /data/html/wordpress;
               fastcgi_pass   192.168.1.26:9000;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
        }

    location /discuz {
        alias       /usr/local/nginx/html/discuz/;
        index       index.php;
        try_files $uri $uri/ /index.php$is_args$args;
    }


    location /wordpress {
            alias   /usr/local/nginx/html/wordpress/;
            index    index.php;
            try_files  $uri $uri/ /index.php$is_args$args;
    }

    不是同一台就要在nginx配置proxy_pass转发

    location /discuz {
       proxy_pass discuz项目的ip:端口；
    }


    location /wordpress {
        proxy_pass wordpress项目的ip:端口；
    }
