有谁知道哪个sebool允许httpd写访问/home/user/html?当我禁用 SELinux 时echo 0 > /selinux/enforce
我可以写入,所以我的问题肯定与 SELinux 有关。我只是不知道哪一个是正确的,而不打开一个大洞,谷歌也没有提供太多帮助。

答案1
它们都不是,至少本身不是。您必须为目录结构提供 的上下文,或者为它们提供和启用和/或的httpd_sys_rw_content_t
上下文,如下所示:public_content_rw_t
allow_httpd_anon_write
allow_httpd_sys_script_anon_write
chcon -R -t httpd_sys_rw_content_t /path
有关详细信息,请参阅httpd_selinux(8)
手册页。
答案2
虽然最好在httpd_sys_rw_content_t
需要的地方标记文件和文件夹,但为了完整起见,我想我会提到您也可以将 seboolean 更改httpd_unified
为 1 以使 SELinux 忽略这个特定的上下文要求,这仍然比禁用 SELinux 好得多,因为互联网上的许多人都会提出建议。
从手册页:
httpd 可以配置为不根据上下文区分文件控制,即所有标记为 httpd 上下文的文件都可以读/写/执行。将此布尔值设置为 false 允许您设置安全策略,以便一个 httpd 服务不能干扰另一个服务。
setebool -P httpd_unified 0
答案3
您可以在 RedHat 上找到关于 selinux 的非常好的文档,您可以下载 180 页的 .pdf 手册,但处理 selinux 问题的最佳方法是打开终端并使用自动化工具进行输入。
尝试:
aureport -a(作为 root)
然后重复导致问题的行为。您将得到问题的良好显示以及您可能想要考虑修复它的方法(在我的例子中,它是 apache 无法写入的文件夹)。
aureport 启动一个报告程序,当出现问题时,该程序将为您提供多种替代方案。会说英语的人可以清楚地解释它们。我花了几个小时解决一个 selinux 问题,然后找到了 redhat 文档中的这个小宝石,并在 30 秒内解决了问题。其中一个选择是正确的。

semanage permissive -a httpd_t
