我正在尝试添加缓存为了代理人&快速CGI但当我尝试查看网站上的任何页面时，它就会失败500内部服务器错误当我尝试在日志中搜索任何错误时，我发现nginx无法访问缓存文件夹：

我试图更改权限/var/lib/nginx/缓存到读&写：

sudo chmod -R u=rw /var/lib/nginx/cache
sudo chmod -R g=rw /var/lib/nginx/cache
sudo chmod -R o=rw /var/lib/nginx/cache

和所有者/var/lib/nginx/缓存根（我试过了nginx用户也一样):

sudo chown -R root:root /var/lib/nginx/cache

编辑：我刚刚发现/var/lib/nginx/缓存应该给予许可执行为了用户&团体&其他：

sudo chmod -R u=rwx /var/lib/nginx/cache
sudo chmod -R g=rwx /var/lib/nginx/cache
sudo chmod -R o=rwx /var/lib/nginx/cache

但一旦我重新启动nginx，它会再次抛出这些错误

答案1

错误消息类型

open() "<file>" failed (13: Permission denied)

通常与 SELinux 或 AppArmor 相关。

您需要遵循文档将 NGINX 和 NGINX Plus 与 SELinux 结合使用或根据您的需要采用它。
