Nextcloud⧫

How to install & configure Nextcloud⧫

About mariadb and the database⧫

⚠️ TON_USER = YOUR user, in lower case ⚠️

⚠️ ndd.tld = YOUR domain, in lowercase ⚠️

⚠️ Commenting means adding a # at the start of the line so that the config file does not take it into account ⚠️

In order to avoid future errors and optimize your installation, it is better to opt for an installation with Mariadb and not SQLite!

Here is the information needed for an installation with Mariadb:

505-828-max

  • Login: choose yours and leave toto alone :0)
  • Password: choose a strong password!
  • Data directories: /data
  • Database user: nextcloud
  • Database password: nextcloud
  • Database name: nextcloud
  • Database host: db-nextcloud

Click on Install, you are free to leave the recommended applications checked. It is always possible to install them afterwards.

Remember to update your Nextcloud before any other operation!!⧫

This tutorial is valid for the latest version: 20.0.4⧫

Set security alerts⧫

After installing Nextcloud it is necessary to adjust the security alerts present in:

Settings / Overview / Security warnings & configuration

https://nextcloud.ndd.tld/settings/admin/overview

1582-500-max

For the alert:
“The “Strict-Transport-Security” HTTP header is not configured for at least “15552000” seconds. To enhance security, we recommend enabling HSTS as described in our security tips ↗. »

nano /opt/seedbox/docker/TON_USER/nextcloud/conf/nginx/site-confs/default

Add this line:
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

Like this (for example):

769-132-max

Save the edited file.

We relaunch Nextcloud and its database by doing:

docker restart nextcloud db-nextcloud

For the alert: The database has some missing indexes. Adding indexes to large tables can take some time. They are therefore not added automatically.

docker exec -ti nextcloud bash

occ db:add-missing-indices

For the alert: Some columns in the database have not been converted to big int. Changing the column type in large tables can take a long time, so they were not converted automatically.

docker exec -ti nextcloud bash

occ db:convert-filecache-bigint Validate

Following columns will be updated:

  • federated_reshares.share_id
  • share_external.id
  • share_external.parent

This can take up to hours, depending on the number of files in your instance!
Continue with the conversion (y/n)? Choose y, of course!

You get your sacred green V again ;)

1575-187-max

For the alert:

Your installation does not have a default region prefix. This is necessary to validate phone numbers in profile settings without a country code. To allow numbers without a country code, please add “default_phone_region” with the respective ISO 3166-1 code of the region in your configuration file.

You must modify the config.php file:

nano /opt/seedbox/docker/TON_USER/nextcloud/conf/www/nextcloud/config/config.php

add to last line
'default_phoneregion' => 'FR',

example:
  'dbhost' => 'XXX',
  'dbport' => '',
  'dbtableprefix' => 'oc',
  'mysql.utf8mb4' => true,
  'dbuser' => 'XXX',
  'dbpassword' => 'XXX',
  'installed' => true,
  'default_phone_region' => 'FR',

Save the edited file.

We relaunch Nextcloud and its database by doing:

docker restart nextcloud db-nextcloud

Add dark mode to Nextcloud⧫

Probably the most followed and coolest app for a dark theme.

https://apps.nextcloud.com/apps/breezedark

It works like any other app in the Nextcloud store.

Here’s a preview:

In the application part of Nextcloud, you just need to enter dark as a keyword and install it.

Clear the cache and reload the page to see the effects!

Mount home in Nextcloud⧫

https://mondedie.fr/d/10779-docker-monter-le-home-dans-nextcloud

Mount the home in Nextcloud without modifying files⧫

It’s very simple, just go to the Applications part of your Nextcloud installation.
Search for the External storage support application and install it.

Once installed, go to Settings then in the left column in External storage:

Now fill in the requested parameters:

  • A folder name: at your convenience
  • In external storage: choose… local :)
  • Authentication: none
  • Configuration: here you will need to enter the path that leads to your home.

For those who use Gdrive: /home/TON_USER/Medias/

For those who NOT use Gdrive: /home/TON_USER/local/

  • Available for: it’s up to you, otherwise leave it by default if there are no restrictions

So that you can share your files and/or folders, make sure to click on the … as shown in the screenshot and click on Allow sharing

Check that a green V is present as in the screenshot, you’re done!

Double authentication | 2fa⧫

Increase the security of your account with double authentication (two-factor authentication or 2fa)!

Go to the Applications section of your Nextcloud.

Find and install: Two-Factor TOTP Provider
Go to Settings
Choose Security at the top left (https://ndd.tld/settings/user/security)

At this step, all you need to do is launch your favorite application for double authentication and scan the QR Code.
In this case we will use Google Authenticator, available here: https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=fr

Now that the application is launched, you should see this:

Click on Get started
Select Scan a barcode

Your account is added!

Don’t forget to enter the code returned by Google Authenticator in Nextcloud to verify everything:

Nextcloud with Talk⧫

We start by updating the script:

cd /opt/seedbox-compose/

git pull

We install Nextcloud:

cd /opt/seedbox-compose/

./seedbox.sh

Choose option 2, then option 1. Select Nextcloud in the list of applications with the Space bar, using the TAB(ulation) key on your keyboard, select OK and validate.

Go to Nextcloud and download Talk in the applications section:

https://nextcloud.ndd.tld/settings/apps and type in search “Talk”.

Once installed you must go to this address, which corresponds to Parameters / Discussion (bottom left):

https://nextcloud.ndd.tld/settings/admin/talk

Fill in the information as shown in the screenshot:

  • STUN servers: the IP of your server followed by the port: 3478
  • TURN servers: the IP of your server followed by the port: 3478
  • Secret: indicate the code after static-auth-secret in your turnserver.conf file:

nano /opt/seedbox/docker/YOUR_USER/coturn/turnserver.conf

Important
Consider opening port 3478 in iptables

It’s finished, Talk is now functional.

Nextcloud with Collabora⧫

You already have Nextcloud installed with the script (without data loss)⧫

We start by updating the script:

cd /opt/seedbox-compose/

git pull

Now we will copy the nextcloud.yml file:

cp /opt/seedbox-compose/includes/dockerapps/nextcloud.yml /opt/seedbox/conf

We reset Nextcloud:

cd /opt/seedbox-compose/

./seedbox.sh

Choose option 2, then option 3. Select Nextcloud in the list of applications with the Space bar, using the TAB(ulation) key on your keyboard, select OK and validate.

Go to Nextcloud and download Collabora in the applications section:

https://nextcloud.ndd.tld/settings/apps

Once installed, go to the configuration section of Collabora:

https://nextcloud.ndd.tld/settings/admin/richdocuments

Indicate your subdomain as shown in the screenshot: https://collabora.ndd.tld and validate with Apply.

You do not yet have Nextcloud installed⧫

We start by updating the script:

cd /opt/seedbox-compose/ && git pull

We install Nextcloud:

cd /opt/seedbox-compose/ && ./seedbox.sh

Choose option 2, then option 1. Select Nextcloud in the list of applications with the Space bar, using the TAB key on your keyboard, select OK and validate.

Go to Nextcloud and download Collabora in the applications section:

https://nextcloud.ndd.tld/settings/apps

Once installed, go to the configuration section of Collabora:

https://nextcloud.ndd.tld/settings/admin/richdocuments

Indicate your subdomain as shown in the screenshot: https://collabora.ndd.tld and validate with Apply.

Unauthorized WOPI host⧫

You may one day get an error like this: “Unauthorized WOPI host”.

To fix this, follow this procedure:

  • Output the file: docker cp collabora:/etc/loolwsd/loolwsd.xml /opt/loolwsd.xml
  • Then edit the loolwsd.xml file: nano /opt/loolwsd.xml

Update the storage tag by adding two lines, one for the IP of your server, the other for the domain of your Nextcloud instance:

<host desc="Regex pattern of hostname to allow or deny." allow="true">1\.2\.3\.4</host>

<host desc="Regex pattern of hostname to allow or deny." allow="true">nextcloud.yourdomain.tld</host>

  • Reinject the loolwsd.xl file: docker cp /opt/loolwsd.xml collabora:/etc/loolwsd/loolwsd.xml

It’s finished and functional :)
