问题描述
我们需要一些脚本生成的配置文件的网络服务，如根据用户输入DHCP，DNS和网络。这些都需要root权限，但我不知道如何运行PHP应用程序根目录。它是通过公开的网络界面运行。
We need some scripts to generate config files for network services such as DHCP, DNS and Network based on user input. These require root access, but I don't know how to run the PHP application as root. It's run through a public web interface.
推荐答案
呀，授予root用户权限到PHP或Web服务器从来都不是一个很好的做法，不管如何保护您的安装。
Awww... granting root rights to PHP or the web server is never a good practice, no matter how secure your setup.
如何让PHP写更改配置文件到一个临时目录：
How about having PHP write the changed configuration files into a temporary directory:
/home/system/transfer/apache/httpd.conf
/home/system/transfer/system/dhcp.conf
/home/system/transfer/mysql/my.ini
和须藤 cron作业运行shell脚本从那里下载他们，将它们复制到合适的位置（也考虑重新启动服务的关怀和所有），上一个五分钟的依据是什么？
and a sudo cron job running a shell script fetching them from there, and copying them to the proper location (also taking care of restarting services and all that), on a five-minute basis?
这会比具有网络/ PHP的用户直接写配置文件更安全一点，再加上它会相对容易建立一个版本的过程，允许回滚一个配置文件到一个较早的版本。
It would be a bit safer than having the Web/PHP user write the configuration files directly, plus it would be relatively easy to set up a versioning process that allows to roll back a configuration file to an earlier version.
