Installing Nextcloud on DigitalOcean Ubuntu Server

Prerequisites

In order to complete the steps in this guide, you will need the following:

A DigitalOcean droplet with Ubuntu Server 20.04. Basic plan is fine for me.

Be sure to update the server: sudo apt update && sudo apt upgrade

A non-root sudo-enabled user and firewall configured on your server.

  • Add a user on Ubuntu: adduser name
  • Add user to sudo group: usermod -aG sudo name

A domain name pointed to your server.

Installing Nextcloud

sudo snap install nextcloud

The Nextcloud package will be downloaded and installed on your server.

snap changes nextcloud

To verify it’s installed.

Configure Administrative Account

sudo nextcloud.manual-install name password

This make a take a few minutes. If successful you should get the output: Nextcloud was successfully installed

Adjusting The Trusted Domains

sudo nextcloud.occ config:system:get trusted_domains

View the trusted_domains array. At first, the only trusted domain is localhost.

sudo nextcloud.occ config:system:set trusted_domains 1 –value=example.com

  • Adds an entry for our domain.
  • To verify, again run: sudo nextcloud.occ config:system:get trusted_domains

SSL and Let’s Encrypt

sudo ufw allow 80,443/tcp

Opens the ports in the firewall that Let’s Encrypt uses to validate domain ownership.

sudo nextcloud.enable-https lets-encrypt

Requests a Let’s Encrypt certificate. You will be asked if your server meets the conditions necessary to request a certificate. Answer “y”.

Please enter an email address (for urgent notices or key recovery):

Please enter your domain name(s) (space-separated): example.com

Login to Nextcloud

Go to https://example.com

Since you have already configure an administrator account from the command line, you will be taken to the Nextcloud login page.

After logging in…

The first time you enter, a window will be displayed with some introductory text and links to various Nextcloud clients that can be used to access your Nextcloud instance.

Firewall

sudo apt install ufw

sudo vim /etc/default/ufw

Ubuntu server has IPv6 enabled, ensure that UFW is configured to support IPv6 so that it will manage firewall rules for IPv6 in addition to IPv4. Set: IPV6=yes

sudo ufw allow ssh OR sudo ufw allow 22

sudo ufw enable
