1.sudo apt-get install spawn-fcgi
原先我是安装php-fpm的，结果那个东西搞死就是设置不好，于是废掉，改用spawn-fcgi. 这玩意原先是lighttpd的组件，后来独立了，完全可以单独安装，并且配合nginx使用。
配置nginx和spawn-fcgi：修改/etc/nginx/fastcgi_params，加入下面这一行：
1.sudo apt-get install spawn-fcgi
在/etc/php5/cgi/php.ini中找到cgi.fix_pathinfo=1这一行，把前面的注释去掉。这样php-cgi才能正常使用SCRIPT_FILENAME这个变量
打开/etc/nginx/sites-available/default文件，稍做修改。我把我的贴在这里：

listen [::]:80 default ipv6only=on; ## listen for ipv6
