        index index.php index.html index.htm;
    }

取消如下内容的注释，并设置字体加粗部分为Nginx的默认路径，如下图所示：

    location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    }

按Esc键退出编辑模式，并输入:wq保存后退出。
