function.fopen:无法打开流:PHP中的权限被拒绝 [英] function.fopen: failed to open stream: Permission denied in PHP

问题描述

我正在尝试通过PHP应用程序为我的网站创建XML网站地图.这个想法是创建一个新文件或覆盖一个现有文件.当我调用fopen时，出现以下错误:

I'm trying to create XML sitemaps for my website from my PHP application. The idea is to either create a new file or overwrite an existing file. When I call fopen, I get the following error:

[function.fopen]: failed to open stream: Permission denied

我正在尝试写到Webroot，其权限为:755.这意味着所有者具有写权限，对吗?我需要做什么才能使脚本能够写入此文件夹? 777会是一件坏事，对吧?我可以以所有者身份运行脚本吗?

I'm trying to write to the webroot and its permissions are: 755. This means that the owner has write permission, right? What do I need to do to make my script be able to write to this folder? 777 would be a bad thing, right? Can I run my script as owner somehow?

谢谢.

推荐答案

是的，正如您所说，使用777可能是一个巨大的错误.网络服务器不能与用于创建文件和文件夹的用户一起运行.

Yep, as you've said, using 777 could be huge mistake. The webserver doesn't run with the same user as you use to create files and folders.

您有一些选择:

• 使用具有写权限的用户(而不是apache用户)作为cronjob运行站点地图创建.
• 将站点地图放在另一个目录中，并设置一个302 Redirect或符号链接.在这种情况下，如果您遇到一个安全问题，请他人编写您的sitemap.xml，至少他们将无法创建具有更危险扩展名的另一个文件(例如PHP，这可能会导致网站入侵).
• 制定重写规则，将所有匹配项重定向到sitemap.xml，并重定向到输出相应XML的php脚本.

• Run the sitemap creation as a cronjob, using an user with rights to write there, other than the apache user.
• Put the sitemap in another directory, and the set up a 302 Redirect or a symlink. In this case, if you have a security issue that let's someone to write your sitemap.xml, at least they'll not be able to create another file with a more dangerous extensions (like PHP, which may result in a site intrusion).
• Make a rewrite rule to redirect any hit to sitemap.xml, to a php script that outputs the appropriate XML.
