Installing and Configuring ownCloud on Ubuntu 20.04

What is ownCloud?

With ownCloud you can 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.

ownCloud has plenty of compelling features:

• Versioning: A file history permits you to roll back to a previous version.
• Encryption: ownCloud protects user data in transit; when it’s transmitted between client and server.
• Drag and drop upload: Drag files from your desktop file manager to your ownCloud instance.
• Theming: Change the look of your ownCloud instance.
• Viewing ODF files: You can view Open Document Format files such as .odt documents and .ods spreadsheets.
• Expansion via installable applications: From within the ownCloud Marketplace, you can install a number of official and third party applications.
• A mobile app for Android and iOS: Mobile apps allow you to interact with your ownCloud server, such as for syncing, uploading, downloading, and viewing files.

Why would you want to host your own cloud? Some common reasons are:

• To save sensitive data, but not on a third-party, commercial option.
• You work from home and you need a private cloud to be used only by those in your household.
• You own a small business and want to keep everything in-house.
• You need an expandable storage solution.

This tutorial walks you through the steps to install ownCloud on Ubuntu 20.04, one of the most user-friendly server operating systems available. There are only a few steps to install ownCloud on Ubuntu 20.04. You install the LAMP (Linux Apache MySQL/MariaDB PHP) stack; create a database and database user; configure Apache; and set up ownCloud using its graphical user interface.

Before You Begin

1. If you have not already done so, create a Linode account and Compute Instance. See our Getting Started with Linode and Creating a Compute Instance guides.

2. Follow our Setting Up and Securing a Compute Instance guide to update your system. You may also wish to set the timezone, configure your hostname, create a limited user account, and harden SSH access.

Note

If you have a registered domain name that you want to point to your ownCloud instance, then use the Linode DNS Manager to point the domain to the Linode server on which you plan to install ownCloud. If you do not have a registered domain name, then replace example.com with the IP address of the Linode server when following the steps in the Create an Apache Configuration File section.

Install ownCloud

Install the LAMP Stack

ownCloud requires a full LAMP (Linux, Apache, MySQL, PHP) stack. In this section, you complete the steps to install a LAMP stack on your Linode. Although you don’t have to use Apache as the web server, the ownCloud developers highly recommend it over web servers like NGINX and lightHTTP.

1. Install the LAMP stack with a single command:

    sudo apt-get install lamp-server^ -y
   

2. When the installation is complete, enable and start Apache:

    sudo systemctl start apache2
    sudo systemctl enable apache2
   

3. Start and enable the MySQL database:

    sudo systemctl start mysql
    sudo systemctl enable mysql
   

4. Set a MySQL admin password and secure the installation:

    sudo mysql_secure_installation
   

   During this process, the system asks if you want to enable the VALIDATE PASSWORD COMPONENT. This feature ensures that all created passwords are strong and unique. Answer n (as in “no”). When prompted, type and verify a new secure password for the MySQL admin user. You are then prompted to answer four questions, to all of which you should respond y (as in “yes”).

5. Install PHP and all the required PHP packages

    sudo apt-get install php php-opcache php-gd php-curl php-mysqlnd php-intl php-json php-ldap php-mbstring php-mysqlnd php-xml php-zip -y
   

6. Restart Apache to enable any changes:

    sudo systemctl restart apache2
   

Create the ownCloud Database

Now that you have installed the prerequisites, it’s time to create the ownCloud database and user. The commands in this section are issued from within the MariaDB console.

1. Access the MariaDB console:

    sudo mysql -u root -p
   

2. create your ownCloud database:

    CREATE DATABASE ownclouddb;
   

3. Create a new user with the necessary privileges, including a strong and unique password. Be sure to substitute PASSWORD with your own password:

    GRANT ALL ON ownclouddb.* TO 'ownclouduser'@'localhost' IDENTIFIED BY 'PASSWORD';
   

4. Flush your database’s privileges:

    FLUSH PRIVILEGES;
   

5. Finally, exit the database console:

    exit
   

Download ownCloud

At this point, the system is ready for ownCloud. Before you actually download the software, check the ownCloud downloads page to confirm the most recent version.

1. Download ownCloud. As of writing this guide, the latest version is 10.5.0. Replace 10.5.0 with the version you want to download.

    wget https://download.owncloud.org/community/owncloud-10.5.0.zip
   

2. Unzip the downloaded file:

    unzip owncloud-10.5.0.zip
   

   Note

   If necessary, install unzip with the command:

   sudo apt-get install zip -y
   

3. When you unzip the file, a new directory named owncloud is created. Move the new directory to the Apache document root. This example uses the default directory for Apache site files:

    sudo mv owncloud /var/www/html/
   

4. Change the ownership of the owncloud directory:

    sudo chown -R www-data: /var/www/html/owncloud
   

Create an Apache Configuration File

Apache requires a virtual host configuration file in order to server your ownCloud instance to the web.

1. Create an Apache configuration file using the Nano text editor:

    sudo nano /etc/apache2/sites-available/owncloud.conf
   

2. Paste the following text into the new file. Replace mentions of example.com with your own domain name or your Linode’s IP Address:

File: /etc/apache2/sites-available/owncloud.conf

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<VirtualHost \*:80> ServerAdmin admin@example.com DocumentRoot /var/www/html/owncloud ServerName example.com <Directory /var/www/html/owncloud> Options FollowSymlinks AllowOverride All Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/example.com_error.log CustomLog ${APACHE_LOG_DIR}/your-domain.com_access.log combined </VirtualHost>

1. Save and close the file by typing Ctrl + O and then, Ctrl + X:

2. Enable the rewrite, mime, and unique_id Apache modules:

    sudo a2enmod rewrite mime unique_id
   

3. Restart the Apache server:

    sudo systemctl restart apache2
   

The command line portion of the installation is complete.

Configure ownCloud

This section covers the web-based portion of the installation.

1. Open a web browser and navigate to your site’s domain, if it has been configured to use a domain name like, http://example.com/owncloud. If you configured Apache to point to your server’s IP address, navigate to http://192.0.2.0/owncloud and replace the example IP address with your own. You should see the ownCloud web-based installer.

2. Type a username and password for the admin user; click the Storage & Database drop-down; and then click MySQL/MariaDB.

3. The database information section is now available. Enter the following information:

   • Database User: ownclouduser
   • Database password: the password you set for the ownCloud database user
   • Database: ownclouddb
   • Localhost: leave as the default

   

4. Click Finish setup. When the install completes, the ownCloud login page appears. Login with the newly-created admin credentials. Once logged in, you are taken to the main ownCloud page.

You now have a working instance of ownCloud, running on Ubuntu 20.04.
