Run Nextcloud from Subdirectory

[studio315b]

How do you tell nextcloud that it's in a sub-directory? Currently each service on my machine is in its own docker instance, and I use Traefik to expose them to different sub-directories on my server:

mydomain/service1
mydomain/service2

Current Behaviour

all links are "/index.php/*"

Desired Behavior

all links are "/nextcloud/index.php/*"

[datenfahrt]

if I understood you correctly - you have to adjust your nextcloud configuration:

'overwritewebroot'

Look this:

https://docs.nextcloud.com/server/13/admin_manual/configuration_server/reverse_proxy_configuration.html#overwrite-parameters

This is what I was looking for. Is there a way to set this setting via docker, or do I need to modify my version of the image?

Depending on how you run the docker container. If you mount your filesystem in /var/www/html, for example, you don't need to rebuild the container. You can find the config file in the mounted directory.

can you show us some example, I tried everything I could( 'overwritehost' => '', htaccess.RewriteBase' => , etc.), still failed.

I had a similar problem and I have created a fix for this issue (Pull request : #527) that contains the an ENV variable NEXTCOULD_OVERWRITEWEBROOT to help define "subdirectories".

Hope it helps,

Hi,
I am sorry maybe i didn’t get something but in 16.0.3 version , I still have troubles to access to nextcloud with subdirectories as http://myserver/nextcloud/login

anything a do and every variable i use ( like
overwrite.cli.url
'htaccess.RewriteBase' ...)

i get a redirection to http://myserver/login

except if a use the variable
'overwritewebroot' => '/nextcloud’

but in this case i have ERR_TOO_MANY_REDIRECTS error

Is there something i missed ?

Thank you
Best regards

Hi all!
I have the same issue. Migrating to using docker and need nextcloud to use the URL /nextcloud as I have multiple web services all using different folders.

I too get the ERR_TOO_MANY_REDIRECTS error

I've also tried fiddling with the
'htaccess.RewriteBase' => '/nextcloud',
setting as well as RewriteBase / in .htaccess no success. (On some occasions all files were deleted when docker container was started)

PR #527 seems to have morphed into something different so not sure what the fix is for this as I can't get this to work either. What am I missing?

I've excatly the same issue and looking for a solution.

[johnjore]

Solution, for me, was to have all connections go via proxy when using 'overwritewebroot' => '/nextcloud’

If URL is used via web browser (local network) without reverse proxy => ERR_TOO_MANY_REDIRECTS
With proxy (from internet/external), logon screen appears.

Need to do more validation and testing, but looks good so far.
config.php

  'overwritewebroot' => '/nextcloud',
  'trusted_proxies' =>
  array (
    0 => 'IP_of_my_proxy',
  ),
  'forwarded_for_headers' =>
  array (
    0 => 'HTTP_X_FORWARDED_FOR',
  ),

nginx

    location /nextcloud/ {
        proxy_headers_hash_max_size 512;
        proxy_headers_hash_bucket_size 64;
        add_header Front-End-Https on;
        proxy_pass http://server/;
    }

ymmv...

---

Update: After moving data and re-using previous DB, Android client re-connected and resumed without any reconfiguration when connecting via proxy. Without going through the proxy, it does not work (at all), lots of errors and timeouts.

I would suspect that 'overwritewebroot' not working when connecting directly is a bug, as per a number of posts here, and hopefully it gets fixed at some point.

[wolftobias]

I tried everything, not working, by the way I use nextcloud docker image

[Energy23]

My configuration is almost the same.
Nextcloud running in a docker container und nginx as webserver / proxy.
The overwritewebroot command didn't work for me either, what is working is the nginx config:

location /nextcloud {
        proxy_pass http://localhost:8080;
        proxy_set_header X-Forwarded-Host $host:$server_port;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location = nextcloud/.well-known/carddav {
      return 301 $scheme://$host/remote.php/dav;
    }
    location = nextcloud/.well-known/caldav {
      return 301 $scheme://$host/remote.php/dav;
    }

Inside the Docker container, I moved the nextcloud files from /var/www/html to /var/www/html/nextcloud
Then I edited the .htaccess file in the /var/www/html/nextloud almost at the bottom line from
RewriteBase / to RewriteBase /nextcloud

Hope that helps, it seems that the command overwritewebroot does not affect the apache config.

The problem with the container restart doesn't affect this config. After a restart there are new files in the /var/www/html folder of a "fresh" nextcloud installation copied.

Here is are some lines of my config.php

<?php
$CONFIG = array (
  'htaccess.RewriteBase' => '/nextcloud/',
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'apps_paths' =>
  array (
    0 =>
    array (
      'path' => '/var/www/html/nextcloud/apps',
      'url' => '/apps',
      'writable' => false,
    ),
    1 =>
    array (
      'path' => '/var/www/html/nextcloud/custom_apps',
      'url' => '/custom_apps',
      'writable' => true,
    ),
  ),
  'instanceid' => '
  'passwordsalt' => '',
  'secret' => '',
  'trusted_domains' =>
  array (
    0 => 'localhost:PORT',
  ),
  'datadirectory' => '/var/www/html/nextcloud/data',
  'dbtype' => 'mysql',
  'version' => '16.0.1.1',
  'overwrite.cli.url' => 'http://localhost:PORT/nextcloud',
  'dbname' => '',
  'dbhost' => '',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => '',
  'dbpassword' => ,
  'installed' => true,
  'overwritehost' => 'URL',
  'overwriteprotocol' => 'https',
  'trusted_proxies' =>
  array (
    0 => 'https://***.de',
    1 => 'https://***.de',
  ),
  'mail_smtpmode' => 'smtp',
  'mail_smtpsecure' => 'ssl',
...
  'theme' => '',
  'loglevel' => 0,
  'maintenance' => false,
);

After almost giving up i did a final test and found the following to be working.
i created nextcloud with the following command:
podman run --name nextcloud-my -p 8080:80 -v <local_mount_point>:/var/www/html:Z -e -d docker.io/library/nextcloud:18.0.1-apache
vi <local_mount_point>/html/.htaccess
add or change "RewriteBase /" to "RewriteBase /your-sub-context"
vi <local_mount_point>/html/config/config.php
add 'overwritewebroot' => '/your-sub-context',
cd <local_mount_point>/html/
ln -s ../html/ your-sub-context

the symlink is important because otherwise somehow the app does not look at the right path. Most likely configurations within the apache would be required, but i didnt want to modify these as i would have to mount those to my host system then. Anyways, hope that this helps for some of you!

[bakcsa83]

@StokeHead Many thanks! It seems htaccess.RewriteBase in config.php does not do its job.

[waynedpj]

@StokeHead @bakcsa83 thanks to you both but as i documented here i still cannot get Nextcloud served as root but from a subdirectory. it indeed looks like htaccess.RewriteBase does not have an effect but the symlink did not work for me in a non-Docker installation. thanks again.
