按照网上教程，安装了Lnmp环境，会出现神奇的情况，html能够正常访问，但是php文件就是不行。

location ~ \.php$ {
        root           html;
        fastcgi_pass   php_compose:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /www/$fastcgi_script_name;
        include        fastcgi_params;
    }

如上代码，有两点注意：
 fastcgi_pass, 这里默认是127.0.0.1，这里可以改为php_compose或者php_compose的容器IP。

fastcg_param 的SCRIPT_FILENAME，这里有坑的，默认是 /scripts，需要改为 php对的volumes, 上面我用了/www，所以这边用了www，php代码的解析是在php容器内完成的。
