Nginx
Nginx - 為什麼我在 Centos 7 上遇到 403 錯誤，配置和權限似乎設置正確？
我正在嘗試在我的 Centos 7 伺服器上使用 Nginx 1.16.1 設置一個基本的 Web 伺服器。我通常使用 yum 安裝 Nginx，預設頁面在我的瀏覽器中載入。
但是，當我嘗試設置自己的文件根目錄時，即使我相信我的配置（我剛剛更改了預設 nginx.conf 文件中的伺服器根目錄）和文件權限（見下文），我仍然會收到 403 錯誤設置正確。
$ sudo nginx -T

http://$$ server-ip $$和http://$$ server-ip $$/index.html產生 403 錯誤。
http://$$ server-ip $$/whatever.html產生 404 錯誤，因為沒有這樣的文件，這意味著 nginx 至少找到了 index.html。
有什麼想法可能是這裡的問題嗎？
原來這是一個 SELinux 問題，並且該文件的上下文錯誤。怎麼修：
如果它在 /var/www 目錄中：
$ sudo restorecon -R /var/www/test
或者，如果它在其他地方
$ sudo chcon -R -t httpd_sys_content_t DIRPATH
