求教安全设置、文件上传、用户组

torrent_yxd

我需要将安全模式打开，并且需要支持文件上传应该如何设置？nginx.conf:

user  www www;


上传临时目录：/home/wwwroot/tmp

php.ini

safe_mode = On

safe_mode_gid = On

safe_mode_include_dir =

safe_mode_exec_dir = /usr/bin


网站目录所属：

/home root:root

/home/wwwlogs root:root

/home/wwwroot www:www

/home/www www:www

访问网站时是空白的，php_error.log显示如下：
[05-Feb-2012 05:05:33 UTC] PHP Warning:  Unknown: SAFE MODE Restriction in effect.  The script whose uid/gid is 501/501 is not allowed to access /tmp owned by uid/gid 0/0 in Unknown on line 0
[05-Feb-2012 05:05:33 UTC] PHP Fatal error:  Unknown: Failed to initialize storage module: files (path: ) in Unknown on line 0

--------------------------------------------

如果把nginx.conf改成

user root root;

把/home下所有目录及子目录都改成root:root
这样倒是可以显示网页了，但是不是不安全啊，而且上传文件的时候仍旧失败
php_error.log显示如下：
[05-Feb-2012 05:10:27 UTC] PHP Warning:  Unknown: SAFE MODE Restriction in effect.  The script whose uid/gid is 501/501 is not allowed to access /tmp owned by uid/gid 0/0 in Unknown on line 0
[05-Feb-2012 05:10:27 UTC] PHP Fatal error:  Unknown: Failed to initialize storage module: files (path: ) in Unknown on line 0

请老大指导！

不需要你自己修改配置，你改了才会出问题
