Nexctloud

Journey to install Nextcloud on an Ubuntu Server 20.04 LTS instance.

Install

Installed by checking nexcloud on Ubuntu installation wizard. Can be installed later with snap.

Configure proxy

Use case : ports 80 and 443 are directed to my raspberry pi (with local IP 192.168.1.100), and domain name cloud.me.ovh must be redirected to my nexcloud server on IP 192.168.1.110

Configure proxy setting on pi (more info on private httpd repo):

<VirtualHost *:80>
    ServerName cloud.me.ovh
    ProxyPreserveHost On
    ProxyRequests Off
    ProxyPass / http://192.168.1.110/
    ProxyPassReverse / http://192.168.1.110/
</VirtualHost>

Add a file proxy.config.php in folder /var/snap/nextcloud/current/nextcloud/config with following content :

<?php

$CONFIG = [
        'trusted_proxies'   => ['192.168.1.100'],
];

Trust domain

Add a file trust_domain.config.php in folder /var/snap/nextcloud/current/nextcloud/config with following content :

<?php

$CONFIG = [

'trusted_domains' =>
   [
    'cloud.me.ovh',
    '192.168.1.110',
  ],

];

No need to restart system, config is taken into account at web page reload.

Enforce security

On proxy

Follow official instructions on Nextcloud doc

To enable mod_headers on HTTPD : a2enmod headers

On snap installation

sudo nextcloud.enable-https lets-encrypt

Other fixes

As an admin, go to Overview in the Administration panel from Settings. Nexctloud will scan your instance and give you instructions.

TURN Talk

Talk can fail for some users behind annoying firewalls or symmetric NAT.

That can be fixed by using a TURN server.

Synchronisation on Android

Follow these instructions Nextcloud sync documentation.

Warning : if you use an apache proxy, use overwriteprotocol instruction to force https in redirections.

Use OCC

In Ubuntu snap, you can invoke nextcloud CLI with nextcloud.occ command.

Full documentation about OCC on official doc

Migrate data by CLI

First put your files in user space :

sudo cp -a Music /var/snap/nextcloud/common/nextcloud/data/jovian/files/

Then fix ownership of new folder :

sudo chown -R root:root Music

Refresh Nextcloud cache :

sudo nextcloud.occ files:scan --path="/jovian/files/Music"
