Discourse von einem Unterordner (Pfadpräfix) statt einer Subdomain aus bereitstellen

:warning: Offizielle Discourse-Erklärung zur Subfolder-Einrichtung

Wir unterstützen Subfolder-Setups für unsere gehosteten Kunden auf Enterprise-Niveau und höher. Aufgrund der hohen technischen Komplexität der Einrichtung empfehlen wir Ihnen dringend, dieses Setup nicht zu verwenden, es sei denn, Sie sind sehr erfahren mit benutzerdefinierten Subfolder-Setups.

Es ist entscheidend, dass Sie ein tiefes Verständnis haben für

  • NGINX-Setup im Discourse Docker-Container
  • Sichere Weiterleitung der ursprünglichen IP-Adresse mithilfe von benutzerdefinierten Headern in der Proxy-Kette
  • Ratenbegrenzung im Front-Proxy-Server

Wenn Ihnen das alles seltsam und fremd vorkommt, raten wir dringend davon ab, dieses Setup zu verwenden.

Um Discourse von einem Subfolder (auch als Pfadpräfix bekannt) Ihrer Domain aus bereitzustellen, wie z. B. https://www.example.com/=SUBFOLDER=, gehen Sie wie folgt vor!

Docker-Konfiguration

Fügen Sie im Abschnitt env Ihrer Docker-Container-yml-Datei die Einstellung DISCOURSE_RELATIVE_URL_ROOT mit dem gewünschten Subfolder hinzu. Stellen Sie sicher, dass dieser nicht mit einem / endet.

Die Bearbeitung aktualisiert den gesamten Leitfaden.

env:
  ...
  DISCOURSE_RELATIVE_URL_ROOT: /=SUBFOLDER=

Der Abschnitt run erfordert einige Änderungen, um alle Discourse-Routen an die richtige Stelle weiterzuleiten. Hier ist ein vollständiger run-Abschnitt mit Subfolder-Unterstützung:

run:
    - exec:
        cd: $home
        cmd:
          - mkdir -p public/=SUBFOLDER=
          - cd public/=SUBFOLDER= && ln -s ../uploads && ln -s ../backups
    - replace:
       global: true
       filename: /etc/nginx/conf.d/discourse.conf
       from: proxy_pass http://discourse;
       to: |
          rewrite ^/(.*)$ /=SUBFOLDER=/$1 break;
          proxy_pass http://discourse;
    - replace:
       filename: /etc/nginx/conf.d/discourse.conf
       from: etag off;
       to: |
          etag off;
          location /=SUBFOLDER= {
             rewrite ^/=SUBFOLDER=/?(.*)$ /$1;
          }
    - replace:
         filename: /etc/nginx/conf.d/discourse.conf
         from: $proxy_add_x_forwarded_for
         to: $http_your_original_ip_header
         global: true

$http_your_original_ip_header steht für Your-Original-Ip-Header, ein vertrauenswürdiger Header, den Sie am Ursprung festlegen und der die tatsächliche Client-IP enthält.

Dies ist erforderlich, da der Datenverkehr einen zentralen Proxy durchläuft. Wenn Discourse eine öffentliche IP-Adresse hat, können Sie diese fälschen. Wenn Discourse privat ist, kommen Sie möglicherweise mit X-Forwarded-For davon.

Nachdem Sie diese Änderungen vorgenommen haben, bootstrappen Sie Ihren Docker-Container wie gewohnt oder bauen ihn neu, falls Sie einen bestehenden Container ändern.

./launcher bootstrap app

oder

./launcher rebuild app

Im Anhang finden Sie ein vollständiges Beispiel einer yml-Datei für einen eigenständigen Container.

subfolder-sample.yml (3.1 KB)

Bedenken hinsichtlich der Ratenbegrenzung

Wenn Sie dieses Setup wählen, möchten Sie wahrscheinlich Anfragen begrenzen, bevor sie NGINX im Container erreichen. Das bedeutet, dass Sie wahrscheinlich die Verwendung unserer Vorlage zur Ratenbegrenzung vermeiden werden. Es ist sehr schwierig, NGINX im Container so zu konfigurieren, dass es auf einer umgeleiteten IP begrenzt wird, und dies würde komplexe Änderungen an der Vorlage erfordern.

Bestehende Beiträge

Wenn Sie dies mit einer bestehenden Website getan haben, die sich auf einer Subdomain befand, werden Sie feststellen, dass Ihre Uploads fehlerhaft sind. Es gibt ein Tool, das helfen kann, alle Pfade so zu korrigieren, dass sie den Subfolder enthalten. Greifen Sie zunächst auf den Docker-Container zu und navigieren Sie zum Discourse-Verzeichnis:

cd /var/discourse
./launcher enter app
cd /var/www/discourse

Führen Sie dann den remap-Befehl aus, nachdem Sie ein Backup erstellt haben:

RAILS_ENV=production bundle exec script/discourse remap '/uploads' '/=SUBFOLDER=/uploads'

Siehe auch: Use a subfolder (path prefix) to serve Discourse with multiple servers sharing a domain für exotischere Setups.

robots.txt

Nachdem Discourse nun in einem Subfolder läuft, kann es seine robots.txt-Datei nicht mehr bereitstellen, um zu steuern, welche Routen von Webcrawlern gecrawlt werden sollen. Crawler suchen nach der robots.txt-Datei Ihrer Hauptseite (https://www.example.com/robots.txt). Sie müssen den Inhalt der robots.txt-Datei von Discourse (zu finden unter https://www.example.com/=SUBFOLDER=/robots.txt) kopieren und in die robots.txt-Datei Ihrer Hauptseite einfügen.

That remap command wouldn’t work unless I called bundle exec discourse instead of bundle exec script/discourse.

I had to update the external_system_avatars_url site setting, and found I had to also remap things like <subfolder>/user_avatar/<domain>, <subfolder>/plugins, <subfolder>/images, etc…

Thanks for mentioning that @vvanpo :slight_smile:

I managed to get this working but do not know where to link <subfolder>/user_avatar/<domain>.

There is no user_avatar folder in the public folder. Where have you pointed (dest) your user_avatar symbolic link placed into <subfolder> ?

Thanks :wink:

Edit: It seems to work without user_avatar link. Maybe images must be rebuilded in background (sidekiq tasks) and this just take some time.

thanks @vvanpo

here’s what worked for me:

RAILS_ENV=production bundle exec discourse remap '/uploads' '/<subfolder>/uploads'
RAILS_ENV=production bundle exec discourse remap '/user_avatar/<domain>' '/<subfolder>/user_avatar/<domain>'
RAILS_ENV=production bundle exec discourse remap '/images' '/<subfolder>/images'
RAILS_ENV=production bundle exec discourse remap '/plugins' '/<subfolder>/plugins'

Considering the rewrite only matches with the subfolder trailing slash, I think it’s safe to change the location directive to /forum/ in this howto, avoiding a possible clash if there are routes starting with the subfolder string. What do you think?

everything went fine while installing but when I was executing this command

after doing ./launcher enter app I got an error

its works for me too

After following the above-mentioned steps to use discourse in a subfolder, now am getting a new error posted below :

Refused to apply style from '<URL>' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Because of this error, the CSS files of the discourse are not loading and the page is blank. Can someone please help me with this?

Hi, my forum is installed on community.example.com now i want it to move on example.com/community (forum is already ruining) now i have added the env section and run section to yml , can someone answer my queries

  1. What will i add in $http_your_original_ip_header ?
  2. The old domain is community.example.com in DISCOURSE_HOSTNAME: do i have to change it ?
  3. What will be "proxy_pass http://discourse; " section in run

Nothing, that should be copied as written.

That should also be copied as written

Yes, it should now be example.com

After many rebuild it is working fine now , just small issue SSL is not working , Not using any ssl template how to get SSL working

Did you set the LETSENCRYPT_ACCOUNT_EMAIL?

Also, if you have rebuilt more than five (?) times, you’ve got the rate limit and won’t be able to get a certificate for that domain name for a week.

Meine Erfahrung:

force https -> checked

Ich musste auch /assets nach subfolder/assets weiterleiten, sonst würde es für *.js.map 404 auslösen.

… und natürlich ist $http_your_original_ip_header standardmäßig $proxy_add_x_forwarded_for.

Hallo,

Hat jemand versucht, die Unterordnerkonfiguration für eine laufende Discourse-Instanz rückgängig zu machen?

Ich habe eine Instanz so konfiguriert, dass sie diese Konfiguration für einen Unterordner wie /forum verwendet, und es hat funktioniert. Aber schließlich haben wir uns entschieden, die Subdomain-Option zu verwenden, also habe ich versucht, alle Änderungen rückgängig zu machen, d. h. die Variable DISCOURSE_RELATIVE_URL_ROOT und den run-Abschnitt zu entfernen und den Standardabschnitt einzugeben:

run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

Und wenn die Anwendung neu erstellt wird, wird der folgende Bildschirm angezeigt, wenn Sie versuchen, auf die URL (ohne /forum) zuzugreifen:

Und wenn ich zu /forum gehe, wird der folgende Bildschirm angezeigt:

Ich weiß also nicht, welche anderen Änderungen erforderlich sind, damit es wieder funktioniert.

Mit freundlichen Grüßen,
Miguel.

Was ich getan hätte, wäre ein Backup und eine Wiederherstellung auf einem neuen Server. Das hätte Ihren bestehenden Server am Laufen gehalten, bis Sie den neuen testen konnten. Und da er sich auf einer neuen Subdomain befindet, wäre es auf diese Weise viel einfacher gewesen. Aber das hilft Ihnen nicht.

Haben Sie diesen Schritt umgekehrt ausgeführt?

Ich denke, Sie müssen Folgendes tun:

RAILS_ENV=production bundle exec script/discourse remap ‘/forum/uploads’ ‘/uploads’

Aber das erklärt nicht den “Oops”-Fehler. Die Orte, an denen Sie nachsehen sollten, sind die Protokolle in

/var/discourse/shared/standalone/logs/var-log/nginx/

und

/var/discourse/shared/standalone/logs/rails/production.log

Ich habe beide getippt, daher müssen Sie möglicherweise Dinge anpassen, wenn ich mich geirrt habe.

Gerne helfe ich hier so gut ich kann, aber wenn dies als Notfall gilt, für den Sie ein Budget haben, können Sie mich direkt kontaktieren.

wie man soziale Logins zum Laufen bringt, ich meine, was wird jetzt die autorisierte Callback-URI sein

DISCOURSE_HOSTNAME: example.com
DISCOURSE_RELATIVE_URL_ROOT: /forum

wird es example.com oder forum.example.com oder example.com/forum sein (Google und FB akzeptieren diese URL nicht)

1 „Gefällt mir“

Laut Konfigurieren der Facebook-Anmeldung für Discourse
Die Callback-URL lautet https://discourse.example.com/auth/facebook/callback. Für einen Unterordner wäre sie https://discourse.example.com/forum/auth/facebook/callback.

App ging okay, schlug dann aber fehl https://example.com/community/auth/failure?message=no_authorization_code&origin=https%3A%2F%2Fexample.com%2Fcommunity%2F&strategy=facebook#_= _

Entschuldigung, es gab einen Fehler bei der Autorisierung Ihres Kontos. Bitte versuchen Sie es erneut.

Ich bin ziemlich sicher, dass das bedeutet, dass Sie den Unterordnerteil richtig gemacht haben und nun den Facebook-Teil richtigstellen müssen, was erheblich schwieriger ist.
