suPHP - 以属主身份来运行php

通常状态下PHP是以httpd.conf里设定的User身份的权限来运行的，一般默认为apache，httpd等等。有时会遇到权限的问题，可以用perl去写一个cgi script来操作，对于PHP比较熟悉也可以用php来写，然后用
suPHP
这个工具来使其以php文件属主的身份来运行它。
suPHP包括一个Apache的模块(mod_suphp)和一个setuid-root的suphp命令。由于suphp这个命令是setuid-root了的，所以还是有一定风险，尽管作者称到现在还没有发现任何bug。("Although I currently don't know any bug in suPHP I can't guarantee that there aren't any.")
FC4 (Apache 2.0.54 / PHP 4.4.1)下安装配置如下：
下载最新的
suPHP 0.6.1
，解压缩，进入suphp-0.6.1目录：
./configure --prefix=/usr --with-apxs=/usr/sbin/apxs --sysconfdir=/etc/httpd/conf --with-apache-user=apache --with-setid-mode=owner
make
make install
----------
配置文件/etc/httpd/conf/suphp.conf：
----------

...
LoadModule suphp_module modules/mod_suphp.so
...
#在suphp这个目录测试一下
suPHP_Engine on
suPHP_ConfigPath /etc
suPHP_AddHandler x-httpd-php
AddHandler x-httpd-php .php
...
在 /web/document/root/suphp 目录下写个 test_suphp.php 试试：
$output";
