Centos 7 サーバーで Nginx 1.16.1 を使用して基本的な Web サーバーをセットアップしようとしています。通常どおり yum を使用して Nginx をインストールし、ブラウザーにデフォルトのページが読み込まれます。
ただし、独自のドキュメント ルート ディレクトリを設定しようとすると、設定 (デフォルトの nginx.conf ファイルでサーバー ルートを変更しただけ) とファイル権限 (以下を参照) の両方が正しく設定されていると思っていても、403 エラーが発生し続けます。

もちろんサーバーを再起動しました（何度も）。
http://[サーバIP]そしてhttp://[サーバーIP]/index.html403 エラーが発生します。
http://[サーバIP]/whatever.htmlそのようなファイルは存在しないため、404 エラーが発生します。つまり、nginx は少なくとも index.html を見つけます。
ここで何が問題になっているのか、何か考えはありますか?
答え1
これは SELinux の問題であり、ファイルのコンテキストが間違っていたことが判明しました。修正方法:
/var/www ディレクトリにある場合:
$ sudo restorecon -R /var/www/test
あるいは、どこか別の場所であれば
$ sudo chcon -R -t httpd_sys_content_t ディレクトリパス
