我刚刚在 VPS 上安装了 centos 和 virtual min（VPS 安装在 Proxmox 上）我以为我配置好了，直到我尝试访问我上传的第一个网站。它给了我一个 403 Forbidden 您无权访问此服务器上的 /。
error_log如下：
[Sun Sep 20 13:24:20.963516 2015] [mpm_prefork:notice] [pid 5042] AH00170: caught SIGWINCH, shutting down gracefully

我尝试将文件权限更改为正确的用户，但什么也没改变。此时我不知道从哪里开始查找。
我试过
# restorecon -Rv /home/mysite/public_html/
如上所述，但它不会改变任何事情
# grep avc /var/log/audit/audit.log
最后一行结果是：

解决方案（我很抱歉）非常简单：
chmod -R 755 /主页/网站/public_html/
代替
chmod -R 755 /主页/网站/public_html

检查 /var/log/audit.log 中的 SELinux 拒绝，您可能会发现您新上传的网站没有正确标记的文件上下文以允许 httpd 进程读取。
如果您不确定，可以发布命令显示的最新条目：
grep avc /var/log/audit/audit.log
您可以运行restorecon -Rv /path/to/webroot，它可能会被重新正确标记。
此外，apache 至少需要对文件和目录具有读取权限。这将要求您拥有 user:apache 的所有权以及 640/750 的文件/目录权限，或者如果您设置为拥有这些文件的用户，则您需要分别对文件和目录拥有 644/755 的权限。
