Nginx na stiahnutie povolenia chyba - Open() failed (13: Permission denied)

Otázka

Mám webovú stránku s Nginx + Uwsgi + Django kde som externého cestu s názvom /download ak chcete spravovať súbory na stiahnutie v Django (poverení používateľa) a vnútorného cesta /download-nginx skutočne prevezmite súbory na directory /var/wwww/download. Kvôli skúšania, snažil som sa to urobiť so svojím prihlasovacím menom, rovnako ako predvolený program na prenos pošty užívateľa. S nimi som si permission denied chyba na Imdb:

open() "/var/www/download/example.txt" failed (13: Permission denied)

Prečítal som si niekoľko ďalších riešení, TAK hovorím, že problém je, že poskytnuté užívateľovi v poriadku.conf nemá dostatok povolenia. Vec je, že oni majú dosť povolenia:

$ sudo -u nginx stat /var

  File: ‘/var’
  Size: 4096            Blocks: 8          IO Block: 4096   directory
Device: 802h/2050d      Inode: 50331745    Links: 21
Access: (0777/drwxrwxrwx)  Uid: (  996/   nginx)   Gid: (    0/    root)
Context: system_u:object_r:var_t:s0

Change: 2021-11-23 11:21:37.151148760 +0000

Tiež, len v prípade som urobil chmod 777 rekurzívne o directory /var/wwww/download

Môj nginx.conf súbor je nasledovný:

        include /etc/nginx/default.d/*.conf;

    location /download-nginx {

            alias /var/www/download;

        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
    }

}

Download pohľad na moje Django webovú stránku, je nasledovná (aj keď chybu som si istá, že nie je na tento úryvok):

def download(request):
    # Auth code is ommitted #
    response = HttpResponse()
    path = "/var/www/download/example.txt"
    name = "example.txt"
    response['Content-Length'] = os.path.getsize(path)
    response['X-Accel-Redirect'] = "/download-nginx/{0}".format(name)
    del response['Content-Type']
    del response['Content-Disposition']
    del response['Accept-Ranges']
    del response['Set-Cookie']
    del response['Cache-Control']
    del response['Expires']
    return response

Preto moja otázka je: čo by som mal robiť v mojom Centos stroj, aby mohli získať prístup k údajom na /var/www/download a poskytnúť na používateľov, ako webove prvky?

Problém je vyriešený: Courier potreby +x povolenie na každej adresárov. Bolo to vyriešil s:

sudo chmod +x /var
sudo chmod +x /var/www
sudo chmod +x /var/www/download
