This post shows students and new users the steps to install and configure ownCloud on Ubuntu Linux with Apache and the free Let’s Encrypt SSL certificate.

ownCloud is an open source, self-hosted file syncing and file sharing platform similar to Dropbox, OneDrive, and other proprietary online storage services. ownCloud enables private cloud services on users’ own servers. It is extensible through its application that can be installed on mobile devices and desktop computers to access and synchronize your files, contacts and data on all devices and platforms.

If you’re looking for a self-hosted file sharing and sync platform, ownCloud should be a good place to start. We show you how to install and configure ownCloud on your own Ubuntu server with a link to the Let’s Encrypt SSL post.

Also, for students and new users learning Linux, the easiest place to start learning is Ubuntu Linux. Ubuntu is the modern open source Linux operating system for desktops, servers, and other devices.

To get started installing and configuring ownCloud on Ubuntu Linux, follow the steps below.

How to install Apache on Ubuntu Linux

As mentioned above, we will use the Apache web server to run ownCloud. ownCloud requires a web server to function, and Apache is the most popular open source web server available today.

To install Apache on Ubuntu, run the following commands:

sudo apt update
sudo apt install apache2

After installing Apache, the following commands can be used to stop, start and enable Apache services always start every time the server starts.

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

To test if Apache is installed and working, open your web browser and look for the IP address or hostname of the server.

http: // localhost

apache2 test page

If you see the above page in the browser, then Apache is working as expected.

How to install MariaDB on Ubuntu Linux

A database server is required for ownCloud to work. ownCloud stores its content in a database, and MariaDB is probably the best database server available to run ownCloud.

MariaDB is fast, secure, and the default server for almost all Linux servers. To install MariaDB, run the following commands:

sudo apt install mariadb-server
sudo apt install mariadb-client

After installing MariaDB, the following commands can be used to stop, start and enable MariaDB services always start when the server starts.

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Then run the following commands to protect the database server with a root password if you were not prompted to do so during installation.

sudo mysql_secure_installation

When prompted, use the guide below to respond:

If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): PRESS ENTER

Switch to unix_socket authentication [Y/n] n

Change the root password? [Y/n] n

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

All done!

To verify and validate that MariaDB is installed and working, log into the database console using the following commands:

sudo mysql -u root -p

It should automatically log into the database server as we started the login request as root. Only root can login without password and only from server console.

If you see a screen similar to the one shown above, then the server installed successfully.

How to install PHP on Ubuntu Linux

Also, PHP is required to run ownCloud. The PHP packages are added to the Ubuntu repositories. Repository versions may not be the latest. If you need to install the latest versions, you will need to add a third-party PPA repository.

In a third-party repository with the latest versions of PHP, run the following commands.

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

At the time of writing, the latest version of PHP 8.0.

sudo apt update

Then run the following commands to install PHP 8.0 and related modules.

sudo apt install php7.4 libapache2-mod-php7.4 php7.4-imagick php7.4-common php7.4-mysql php7.4-gmp php7.4-imap php7.4-json php7.4-pgsql php7.4-ssh2 php7.4-sqlite3 php7.4-ldap php7.4-curl php7.4-intl php7.4-mbstring php7.4-xmlrpc php7.4-gd php7.4-xml php7.4-cli php7.4-zip

Next, you’ll want to change some PHP configuration settings that work great with ownCloud. Run the following commands to open the default PHP configuration file.

sudo nano /etc/php/7.4/apache2/php.ini

Then change the line settings to be somewhat aligned with the lines below. Save your changes and exit.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

How to create an ownCloud database in Ubuntu

At this point, we are ready to create the ownCloud database. As mentioned above, ownCloud uses databases to store its content.

To create a database for ownCloud, run the following commands:

sudo mysql -u root -p

Then create a database called owncloud

CREATE DATABASE owncloud;

Next, create a database user named ownclouduser and set password

CREATE USER 'ownclouduser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON owncloud.* TO 'ownclouduser'@'localhost' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

How to download ownCloud on Ubuntu

We are ready to download ownCloud and start configuring it. First, run the following commands to download the latest version of ownCloud from your repository.

Next, extract the downloaded content to the Apache root directory. This will create a folder called owncloud.

wget https://download.owncloud.org/community/owncloud-complete-20210721.zip -P /tmp
sudo unzip /tmp/owncloud-complete-20210721.zip -d /var/www

Then run the command below to allow www-data user to own the new owncloud directory.

sudo chown -R www-data:www-data /var/www/owncloud/
sudo chmod -R 755 /var/www/owncloud/

How to configure Apache for ownCloud

We have downloaded the content from ownCloud into a new folder that we call ownCloud. Now, let’s configure Apache to create a new server block to use with our ownCloud website. You can create so many server blocks with Apache.

To do that, run the following commands to create a new configuration file called owncloud.conf at / etc / apache2 / sites-available / directory to host our ownCloud server block.

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

In the archive, copy and paste the content below in the archive and save it.

Alias /owncloud "/var/www/owncloud/"

<Directory /var/www/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off
 </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud

</Directory>

Save the file and close.

After saving the above file, run the following commands to enable the new file that contains our ownCloud server block, as well as other important Apache modules.

Restart Apache after that.

sudo a2ensite owncloud.conf
sudo a2enmod rewrite
sudo a2enmod headers
sudo a2enmod env
sudo a2enmod dir
sudo a2enmod mime

Reload Apache when you have finished the above configuration.

sudo systemctl reload apache2

Now that ownCloud is downloaded and the necessary services are configured, open your browser and start the ownCloud installation by visiting the domain name or IP address of your server followed by / owncloud :

http://localhost/owncloud

However, we want to make sure our server is protected with free Let’s Encrypt SSL certificates. So, continue below to learn how to generate Let’s Encrypt SSL certificate for websites.

How to configure Let’s Encrypt for ownCloud

We have written an excellent post on how to generate and manage Let’s Encrypt SSL certificates for Apache web server. You can use that post to apply here for your ownCloud website.

To read the post on how to generate Let’s Encrypt SSL certificates for the website, click the link below:

How to configure Let’s Encrypt on Ubuntu Linux with Apache

If you managed to generate a Let’s Encrypt SSL certificate, you need to reopen the server block for our ownCloud website by running the following commands.

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

The new ownCloud server block settings should look similar to the following line. Take notes on the highlighted lines.

  • The first server block listens on port 80. It contains a 301 redirect to redirect HTTP to HTTPS.
  • The second server block listens on port 443. It contains a 301 redirect to redirect www to a domain other than www.
<VirtualHost *:80>
  ServerName example.com
  ServerAlias www.example.com
  Redirect permanent / https://example.com/
</VirtualHost>

<VirtualHost *:443>
  ServerName example.com
  DocumentRoot /var/www/
  ServerAlias www.example.com

  Protocols h2 http:/1.1

  <If "%{HTTP_HOST} == 'www.example.com'">
    Redirect permanent / https://example.com/
  </If>
  
  ErrorLog ${APACHE_LOG_DIR}/example.com-error.log

Alias /owncloud "/var/www/owncloud/"

<Directory /var/www/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off
 </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud

</Directory>
 
</VirtualHost>

Save the file above, then restart Apache and PHP using the commands below.

sudo systemctl reload apache2

Finally, if everything went according to plan, you should be able to start the ownCloud setup wizard by navigating to the server’s hostname or IP address via HTTPS.

https://example.com/owncloud

An ownCloud setup wizard should appear. Follow the wizard to complete the setup.

  • Create an administrator account and password
  • leave the default data folder
  • Select MySQL / MariaDB
  • Enter the database username
  • Enter the password of the database user
  • Enter the name of the database
  • Leave the database host as local host if ownCloud and the database server are on the same host.

Click Finish setup
