How to install NextCloud 13 on Debian 9

We’ll show you, how to install NextCloud 13 on Debian 9. Nextcloud is an open-source software suite that allows users to store their data such as files, contacts, calendars, news feed, TODO lists and much more, on their personal servers. It is using standard protocols such as webdavm, carddav and caldav. It also provides client applications so users can easily manage and synchronize their data among Linux, MacOS, Windows platforms and smart phones, which makes Nextcloud a great free alternative to proprietary cloud services such as Dropbox, Google Drive, iCloud, etc…

In this tutorial we will install and configure Nextcloud 13 on a Debian 9 VPS, with Apache web server, PHP and MariaDB.


Before we start with the installation there are several requirements:

  • SSH ‘root’ access to your server.
  • MySQL or MariaDB 5.5+; PostgreSQL version 9 or 10;
  • PHP version 7.0, 7.1 or 7.2.
  • Apache version 2.4 with mod_php or Nginx (php-fpm) web server

Login via SSH and update your system

Login to your Debian 9 VPS via SSH as user root

ssh root@IP_Address -p Port_Number

and make sure that all installed packages are up to date by running the following command

apt update && apt upgrade

Install Apache web server

As mentioned in the requirements, a web server is required to run Nextcloud. Run the following command to install Apache on your VPS

apt install apache2

Once installed, start Apache and enable it to start at server boot

systemctl start apache2
systemctl enable apache2

Install PHP

Install PHP and some PHP modules required by NextCloud

apt install php7.0 libapache2-mod-php7.0 php7.0-common php7.0-gd php7.0-json php7.0-mysql php7.0-curl php7.0-mbstring php7.0-intl php7.0-mcrypt php7.0-imagick php7.0-xml php7.0-zip

Install MariaDB and create a database

Next, we will install MariaDB server using the following command

apt -y install mariadb-server

Start the database server and enable it to start upon server boot

systemctl enable mariadb
systemctl start mariadb

Run the mysql_secure_installation post-installation script to harden the security of your MariaDB server and set a ‘root’ password. You can use the following options


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

Now, login to the MariaDB server as user root and create a new user and database for Nextcloud

mysql -u root -p

MariaDB [(none)]> CREATE DATABASE nextcloud;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud_user'@'localhost' IDENTIFIED BY 'PASSWORD';
MariaDB [(none)]> exit;

Don’t forget to replace ‘PASSWORD’ with an actual strong password. Combination of letters and numbers and minimum 10 characters long is recommended.

Download and install Nextcloud
Go go Nextcloud’s official website and download Nextcloud 13 to your Debian 9 VPS. Currently latest stable version is 13.0.1


Extract the downloaded ZIP archive in a directory Apache has access to, and change the ownership of the nextcloud directory to the web server user

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

Once all Nextcloud prerequisites are fulfilled, we can complete installation using the on-screen installation wizard or through the command line. We will complete the installation through the command line. Change the current working directory

cd /var/www/html/nextcloud

and execute the following command as the web server user

sudo -u www-data php occ  maintenance:install --database "mysql" --database-name "nextcloud"  --database-user "nextcloud_user" --database-pass "PASSWORD" --admin-user "admin" --admin-pass "PASSWORD"

Use the database information we created above and set a strong password for the Nextcloud ‘admin’ user.

If the installation is successfull you will get the following output

Nextcloud was successfully installed

Edit the config/config.php file and add as a trusted domain

nano config/config.php

 'trusted_domains' =>
  array (
    0 => 'localhost',
    1 => '',

Create Apache Virtual Host

If you want to be able to access Nextcloud with a domain name, you will have to create a new virtual host. Create the following file

nano /etc/apache2/sites-available/

<VirtualHost *:80>

DocumentRoot /var/www/html/nextcloud

Alias /nextcloud “/var/www/html/nextcloud/”

<Directory /var/www/html/nextcloud>
Options +FollowSymlinks
AllowOverride All

<IfModule mod_dav.c>
Dav off

SetEnv HOME /var/www/html/nextcloud
SetEnv HTTP_HOME /var/www/html/nextcloud

ErrorLog /var/log/apache2/nextcloud-error_log
CustomLog /var/log/apache2/nextcloud-access_log common


Save the file and enable the newly created virtual host


It is also recommended to enable the mod_headers, mod_env, mod_dir and mod_mime Apache modules

a2enmod headers
a2enmod env
a2enmod dir
a2enmod mime

To activate the new configuration, you need to run the following command

systemctl reload apache2

With this step the Nextcloud 13 installation is completed. You can now visit and login to your Nextcloud instance using the credentials used in the insallation command above.
