Servire Discourse da una sottocartella (prefisso percorso) invece che da un sottodominio

Miguel_Angel_García · 2 Febbraio 2022, 9:26am

Grazie mille per la tua risposta @pfaffman, lo apprezzo davvero.

Approfondendo la questione, ho provato a ripristinare tutte le modifiche in /etc/nginx/conf.d/discourse.conf all’interno del container, accedendovi con /var/discourse/launcher enter app.
Dopo aver ripristinato il file discourse.conf, ho eseguito un rebuild usando /var/discourse/launcher rebuild app.
Ho provato ad accedere al sito web senza /forum, ma è apparso lo stesso errore “Oops” (la prima immagine che ho allegato nel mio commento precedente).

Inoltre, ho provato a eseguire (all’interno del container):

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

ma è apparso un altro errore (penso sia lo stesso che @ahmed_khan1 ha evidenziato):

bundler: failed to load command: script/discourse (script/discourse)

Come modificare `nginx/discourse.conf`

Presumo che qualsiasi modifica a discourse.conf all’interno del container venga comunque ripristinata eseguendo una ricostruzione.

Per mantenere le modifiche, devi in qualche modo aggiungerle alla configurazione del tuo container, ad esempio web_only.yml:

# [… ]
## Ricorda, questa è sintassi YAML - puoi avere solo un blocco con un nome
run:
  - exec: echo "Inizio comandi personalizzati"
# [… ]
  - replace:
      filename: /etc/nginx/conf.d/discourse.conf
      from: $proxy_add_x_forwarded_for
      to: $http_x_real_ip
      global: true
# [… ]

Come eseguire il debug di un’installazione di Discourse in una sottocartella

In un’installazione di Discourse in una sottocartella, una chiamata a Discourse avviene in questo modo:
example.org/forum → [Proxy esterno per example.org] → /path-to-discourse/discourse/shared/web-only/nginx.http.sock → [Nginx nel container web di Discourse]

Quindi, se c’è un errore, dobbiamo prima individuarlo:

Proxy esterno
Nginx nel container Discourse
Discourse stesso

Proxy esterno

Chiamalo in un browser e controlla il risultato.
Controlla i log degli errori del proxy esterno.

Nginx nel container Discourse

Connettiti via SSH al tuo webserver.
Connettiti direttamente al socket tramite curl.
Esegui il debug dell’output di curl e dei log di Nginx in Discourse

Importante: usa l’URL http – e non https.

curl -I --unix-socket /path-to-discourse/discourse/shared/web-only/nginx.http.sock http://www.example.org/forum/

Se questo funziona, prova una chiamata reale come:

curl --unix-socket /path-to-discourse/discourse/shared/web-only/nginx.http.sock \
-H "user-agent: Chrome/88.0.4324.182" \
-H "Accept-Encoding: gzip" \
http://www.example.org/forum/t/test-thread/12345 --output test-encoded.html.gz

Ciao @pfaffman e @rrit,

Ho ulteriori informazioni sul problema. Nel log di Discourse, come ha detto @pfaffman:

l’errore generato è:

Ti suona familiare?

A proposito, @rrit ho provato a cercare il file nginx.http.sock, nella cartella che hai suggerito e anche nell’intero progetto, ma non l’ho trovato, quindi non sono riuscito a provare quello che hai detto

Saluti,
Miguel.

pfaffman · 7 Febbraio 2022, 12:27pm

Non riesco davvero a capire cosa hai fatto o cosa stai cercando di fare.\n\nImmagino che tu non abbia un backup del tuo ultimo database funzionante e del file yml?\n\nPenso che quello che farei sarebbe provare a tornare alla tua ultima configurazione, fare un backup e poi ricominciare su un sito di prova.

rrit · 8 Febbraio 2022, 7:58pm

Mi scuso, mi riferivo a una configurazione come questa:

Configurazione del container web_only.yml:

templates:
# [...]
  - "templates/web.socketed.template.yml"
# [...]
#expose:
#  - "80:80"   # http
#  - "443:443" # https

nginx-site.conf esterno:

server {
    listen 443 ssl default_server;
# [...]
    location ~ ^/forum {
        proxy_pass http://unix:/path-to-discourse/discourse/shared/web-only/nginx.http.sock:;
        proxy_set_header Host $http_host;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Accept-Encoding $http_accept_encoding;
    }
# [...]
}

Miguel_Angel_García · 9 Febbraio 2022, 9:59am

Grazie per la risposta @pfaffman. Ad essere onesti, non ho un backup perché si trattava di un’istanza di test. Quindi non è un grosso problema e sono stato in grado di avviare una nuova istanza con l’approccio del sottodominio.
Ma sono ancora curioso riguardo all’errore che ho riscontrato quando il comando:

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

viene eseguito.
Avresti qualche idea sull’errore?

pfaffman · 9 Febbraio 2022, 3:39pm

Quindi vuoi essere in grado di passare da un’installazione in una sottocartella a una non in una sottocartella? Non lo consiglio. E per lo più nessuno pensa che un’installazione in una sottocartella sia una buona idea.

tig3 · 19 Ottobre 2024, 10:44am

Nel mio caso, lasciandolo così com’è, mostrava 127.0.0.1 per tutti gli utenti, anche se nei log di nginx l’IP dell’utente veniva registrato correttamente.

Applicare la risposta di @varun21 Serve Discourse from a subfolder (path prefix) instead of a subdomain - #111 by varun21 ha risolto il problema.

Grazie @varun21

sergey2 · 8 Gennaio 2025, 3:29am

Grazie per aver pubblicato questa guida! Quando eseguo questo comando nella cartella /var/discourse:

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

ottengo questo errore:

Could not locate Gemfile or .bundle/ directory

Ho installato Ruby con il comando snap install ruby --classic. Non ho molta familiarità con i Gem. Qualcuno potrebbe dirmi cos’altro deve essere installato affinché questo funzioni?

pfaffman · 8 Gennaio 2025, 12:24pm

Devi eseguire il comando all’interno del container

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

Penso che l’ultimo cd potrebbe non essere necessario.

Da un po’ di tempo, notiamo che il container emette frequentemente messaggi X-Accel-Mapping header missing, anche se non per ogni visitatore o ogni passaggio di navigazione. Ho notato che questo header è definito esplicitamente nella configurazione di Nginx, sebbene non per tutte le richieste: discourse/config/nginx.sample.conf at main · discourse/discourse · GitHub

Poiché non vedo questo problema segnalato altrove in questo forum, mi chiedo se possa essere correlato alla configurazione in sottodirectory che utilizziamo, anche se non vedo come.

Non sono sicuro di cosa lo generi esattamente, ma suppongo che ciò accada solo se X-Sendfile-Type è impostato su X-Accel-Redirect, ma X-Accel-Mapping non è definito. La configurazione, però, definisce entrambi o li imposta entrambi vuoti .

In realtà, viene impostato solo quando si accede ai backup e, cosa più rilevante, quando si accede ai file caricati. Ho appena testato e verificato che ogni volta che visualizzo un post con un’immagine caricata o simile, viene generato quel messaggio. Analizzando la configurazione, non dovrebbe essere possibile che X-Accel-Redirect sia impostato mentre X-Accel-Mapping no. Inoltre, si tratta di un header di richiesta impostato da Nginx all’interno del container, consumato esclusivamente da Discourse/unicorn/pitchfork/backend, quindi non entra né esce dal container.

Ah, abbiamo configurato Nginx per registrare gli errori su STDERR e, poiché non vedo questi messaggi nei log di Discourse, sono certo che sia Nginx stesso a generarli. Probabilmente è questo il motivo per cui non è stato notato da altri, dato che compare nel file di log di Nginx. Qualcuno ha tempo di verificare se anche il proprio shared/*/log/var-log/nginx/error.log contiene questi messaggi? Se sì, tornerò a confrontarmi con chi non utilizza una configurazione in sottodirectory per restringere il campo.
