OwnCloud is free and open-source software that enables you to create a private “file-hosting” cloud. OwnCloud is similar to DropBox service with the difference of being free to download and install on your private server. Owncloud made by PHP and backend database MySQL (MariaDB), SQLLite, or PostgreSQL. OwnCloud also enables you to easily view and sync address book, calendar events, tasks, and bookmarks. You can access it via the good-looking and easy-to-use web interface or install the OwnCloud client on your Desktop or Laptop machine (supports Linux, Windows, and macOS).
In this context, we shall look into how to install OwnCloud on Ubuntu 20.04 LTS.
1. Perform System Update
First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal:
$ sudo apt update
$ sudo apt upgrade
2. Install Lamp stack
A LAMP server is required. If you do not have LAMP installed, you can follow our guide here.
3. Install OwnCloud on the system
Now we download the latest version of OwnCloud https://owncloud.com/download-server/:
$ wget https://download.owncloud.org/community/owncloud-complete-20200731.zip
Unpack the OwnCloud archive to the document root directory on your server:
$ sudo unzip owncloud-complete-20200731.zip -d /var/www/html/
We will need to change some folders permissions:
$ sudo chown -R www-data:www-data /var/www/html/owncloud/
$ sudo chown -R 755 /var/www/html/owncloud/
4. Configure MariaDB for OwnCloud
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:
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 the OwnCloud. 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 OwnCloud installation:
CREATE DATABASE ownclouddb;
CREATE USER 'ownclouduser'@'localhost' IDENTIFIED BY 'YOURPASSWORD';
GRANT ALL ON ownclouddb.* TO 'ownclouduser'@'localhost';
5. Configure Apache web server for OwnCloud
Create a new virtual host directive in Apache. For example, create a new Apache configuration file named 'owncloud.conf' on your virtual server:
$ ln -s /etc/apache2/sites-available/owncloud.conf /etc/apache2/sites-enabled/owncloud.conf
$ nano /etc/apache2/sites-available/owncloud.conf
Add the following lines:
allow from all
CustomLog /var/log/apache2/your-domain.com-access_log common
Now, we can restart the Apache webserver so that the changes take place:
$ sudo a2ensite owncloud.conf
$ sudo a2enmod rewrite
$ sudo systemctl restart apache2
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 firstname.lastname@example.org -d example.com
If the test is successful, reload Apache for the change to take effect:
$ sudo apache2ctl -t
$ sudo systemctl reload apache2
To configure ownCloud, we will use the web interface.
So, go ahead and open up a web browser and point it to https://your-domain.com.
You should see a web page where you can enter username and password for the administrator user account, click on the 'Advanced options' hyperlink and enter the data directory (or leave the default setting), then enter database username, database password, database name, host (localhost), and click 'Finish setup'.
Alternately you can also download the ownCloud clients to sync the documents across your devices.
From the home page, you can start uploading the contents using the "+ sign" button.
This article covers the complete process of installing and configuring OwnCloud on Ubuntu 20.04 LTS Focal Fossa system. In fact, OwnCloud allows you to host a private cloud for data synchronization, file storage, and file sharing. You can use ownCloud as an alternative to commercial services like DropBox or Box. This software is great for secure collaboration across your projects and teams.
