php - nginx php fastcgi无法写入，即使使用他自己的权限也被拒绝

Question

嗨，当我使用像 file_put_contents 这样的写入文本功能时，我的权限被拒绝了。我在centos 6环境下使用nginx，我使用php-fcgi

问题只能通过将 dir 权限设置为 777 来解决，但我不想要该解决方案。

这是PHP代码

<?php
    error_reporting(E_ALL);
    header("content-type:text/plain");
    if(isset($_GET['akarapaci'])) {phpinfo();}
    echo getcwd();
    echo "\nscript owner : ".get_current_user()."\n";
    echo "\nscript getmyuid : ".getmyuid()."\n";
    echo "\nscript getmygid : ".getmygid()."\n";

    file_put_contents(dirname(__FILE__)."/X","1");
?>

结果如下:

/var/www/html
script owner : nginx

script getmyuid : 496

script getmygid : 493

代码只是简单的写入文件/var/www/html/X(文件尚未创建)，并有这样的错误

2012/10/27 19:51:59 [error] 1010#0: *32 FastCGI sent in stderr: "PHP Warning:  file_put_contents(/var/www/html/X): failed to open stream: Permission denied in /var/www/html/info.php on line 10" while reading response header from upstream, client: 111.94.49.72, server: vprzl.com, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "vprzl.com"

这是/var/www/中的目录列表

这是我的 nginx.conf

      }
    }

找到了罪魁祸首! (我自己的回答)我只需要更改文件 /etc/init.d/php-fcgi

中的一行

来自

PHPUSER=php

到

PHPUSER=nginx

然后重启
