How To Install Nextcloud on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Nextcloud on Ubuntu 20.04 LTS. For those of you who didn’t know, Nextcloud is an open-source self-hosted file sync and share application (Calendar, Contacts, Documents, Email, and more). The developers at Nextcloud are doing their best to give the users a more secure platform, fewer bugs, and overall a better product.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Nextcloud on a Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Nextcloud on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running these following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Install the LAMP stack.

A Ubuntu 20.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here.

Step 3. Installing Nextcloud on Ubuntu 20.04.

Now we download the latest version of Nextloud:

wget https://download.nextcloud.com/server/releases/nextcloud-20.0.0.zip

Unpack the Nextcloud archive to the document root directory on your server:

unzip nextcloud-20.0.0.zip
mv nextcloud /var/www/html

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/nextcloud

Step 4. Configuring MariaDB for Nextcloud.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for Nextcloud. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Nextcloud installation:

MariaDB [(none)]> CREATE DATABASE nextcloud;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY 'your-strong_password';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Step 5. Configuring Apache web server for Nextcloud.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘nextcloud.conf’ on your virtual server:

touch /etc/apache2/sites-available/nextcloud.conf
ln -s /etc/apache2/sites-available/nextcloud.conf /etc/apache2/sites-enabled/nextcloud.conf
nano /etc/apache2/sites-available/nextcloud.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin admin@yourdomain.com
DocumentRoot "/var/www/html/nextcloud/"
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory "/var/www/html/nextcloud/">
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Restart the Apache webserver so that the changes take place:

sudo a2enmod rewrite
sudo a2ensite nextcloud.conf
sudo systemctl restart apache2.service

Step 6. Set up HTTPS.

We should enable a secure HTTPS connection on Nextcloud. We can obtain a free TLS certificate from Let’s Encrypt. Install Let’s Encrypt client (Certbot) from Ubuntu 20.04 repository:

sudo apt install certbot python3-certbot-apache

Next, run the following command to obtain a free TLS certificate using the Apache plugin:

sudo certbot --apache --agree-tos --redirect --staple-ocsp --email you@example.com -d example.com

If the test is successful, reload Apache for the change to take effect:

sudo apache2ctl -t
sudo systemctl reload apache2

Step 7. Accessing Nextcloud Web Interface.

Nextcloud will be available on HTTP port 80 by default. Open your favorite browser and navigate to https://your-domain.com/ or https://server-ip-address/ and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel. What you do with Nextcloud is up to you. You can add new modules or just use it as cloud-based file sync and share. You can install the Android app and even make use of the ownCloud desktop clients (they’ll work fine with Nextcloud).
