Want to run your own self-hosted cloud storage services in your environment? There are few open source platform that can do that.. and OwnCloud is one of many… OwnCloud works well when done using HTTPS or SSL/TLS..

OwnCloud is an open source software that enables private cloud services on users’ own servers and environments. Like DropBox and other cloud storage services, OwnCloud provides similar functions, and it’s free to download and install on your own servers without paying service providers.

In today’s environments, OwnCloud is frequently being installed with SSL/TLS encryption so that all traffic to and from the platform is protected over HTTPS. This is a great way to secure your data on OwnCloud.

This brief tutorial shows students and new users steps to install and configure OwnCloud on Ubuntu 17.04 | 17.10 Servers with Let’s Encrypt SSL support.

To learn how to install OwnCloud on your servers, follow the steps below:

To get started with installing OwnCloud, follow the steps below:

Step 1: Install Apache2

OwnCloud requires a webserver to function and the most popular webserver in use today is Apache2. So, go and install Apache2 on Ubuntu by running the commands below:

sudo apt install apache2

After installing Apache2, run the commands below to disable directory listing.

sudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/apache2/apache2.conf

Next, run the commands below to stop, start and enable Apache2 service to always start up with the server boots.

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

Step 2: Install MariaDB

OwnCloud also requires a database server to function.. and MariaDB database server is a great place to start. To install it run the commands below.

sudo apt-get install mariadb-server mariadb-client

After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

After that, run the commands below to secure MariaDB server.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

• Enter current password for root (enter for none): Just press the Enter
• Set root password? [Y/n]: Y
• New password: Enter password
• Re-enter new password: Repeat password
• 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

Restart MariaDB server

sudo systemctl restart mysql.service

Step 3: Install PHP and Related Modules

PHP 7.1 isn’t available on Ubuntu default repositories… in order to install it, you will have to get it from third-party repositories.

Run the commands below to add the below third party repository to upgrade to PHP 7.1

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

Then update and upgrade to PHP 7.1

sudo apt update

Run the commands below to install PHP 7.1 and related modules.

sudo apt install php7.1 libapache2-mod-php7.1 php7.1-common libapache2-mod-php7.1 php7.1-mbstring php7.1-xmlrpc php7.1-soap php7.1-apcu php7.1-smbclient php7.1-ldap php7.1-redis php7.1-gd php7.1-xml php7.1-intl php7.1-json php7.1-imagick php7.1-mysql php7.1-cli php7.1-mcrypt php7.1-ldap php7.1-zip php7.1-curl

After install PHP 7.1, run the commands below to open PHP-FPM default file.

sudo nano /etc/php/7.1/apache2/php.ini

Then make the change the following lines below in the file and save.

file_uploads = On
allow_url_fopen = On
memory_limit = 256M
upload_max_filesize = 64M
max_execution_time = 360
date.timezone = America/Chicago

Step 4: Create OwnCloud Database

Now that you’ve install all the packages that are required, continue below to start configuring the servers. First run the commands below to create OwnCloud database.

Run the commands below to logon to the database server. When prompted for a password, type the root password you created above.

sudo mysql -u root -p

Then create a database called owncloud

CREATE DATABASE owncloud;

Create a database user called ownclouduser with new 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' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download OwnCloud Latest Release

Next, visit OwnCloud site to download your free copy. The community edition is what you’ll want to download.

After downloading, run the commands below to extract the download file into Apache2 root directory.

cd /tmp && wget https://download.owncloud.org/community/owncloud-10.0.3.zip
unzip owncloud-10.0.3.zip
sudo mv owncloud /var/www/html/owncloud/

Then run the commands below to set the correct permissions for OwnCloud to function.

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

Step 6: Configure Apache2

Finally, configure Apahce2 site configuration file for OwnCloud. This file will control how users access OwnCloud content. Run the commands below to create a new configuration file called owncloud.conf

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

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/owncloud/
     ServerName example.com
     ServerAlias www.example.com
  
     Alias /owncloud "/var/www/html/owncloud/"

     <Directory /var/www/html/owncloud/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted
          <IfModule mod_dav.c>
            Dav off
          </IfModule>
        SetEnv HOME /var/www/html/owncloud
        SetEnv HTTP_HOME /var/www/html/owncloud
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Save the file and exit.

Step 7: Enable the OwnCloud and Rewrite Module

After configuring the VirtualHost above, enable it by running the commands below

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

Step 8 : Restart Apache2

To load all the settings above, restart Apache2 by running the commands below.

sudo systemctl restart apache2.service

STEP 9: OBTAIN AND CONFIGURE LET’S ENCRYPT SSL CERTIFICATES

Now that the OwnCloud configuration is done, continue below to get Let’s Encrypt installed and configured. Let’s Encrypt now provides a NGinx module to automate this process. To get the client/module installed on Ubuntu, run the commands below

sudo apt-get install python-certbot-apache

After that run the commands below to obtain your free Let’s Encrypt SSL/TLS certificate for your site.

sudo certbot --apache -m admin@example.com -d example.com -d www.example.com

After running the above commands, you should get prompted to accept the licensing terms. If everything is checked, the client should automatically install the free SSL/TLS certificate and configure the Nginx site to use the certs.

Please read the Terms of Service at
https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf. You must
agree in order to register with the ACME server at

This is how easy is it to obtain your free SSL/TLS certificate for your Nginx powered website.

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.
-------------------------------------------------------------------------------
1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.
-------------------------------------------------------------------------------
Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2

Pick option 2 to redirect all traffic over HTTPS. This is important!

After that, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.

Congratulations! You have successfully enabled https://example.com and
https://www.example.com

You should test your configuration at:
https://www.ssllabs.com/ssltest/analyze.html?d=example.com
https://www.ssllabs.com/ssltest/analyze.html?d=www.example.com
-------------------------------------------------------------------------------

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/example.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/example.com/privkey.pem
   Your cert will expire on 2018-02-24. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

The highlighted code block should be added to your Nginx OwnCloud site configuration file automatically by Let’s Encrypt certbot. Your OwnCloud site is ready to be used over HTTPS.

<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/owncloud/
     ServerName example.com
     ServerAlias www.example.com
  
     Alias /owncloud "/var/www/html/owncloud/"

     <Directory /var/www/html/owncloud/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted
          <IfModule mod_dav.c>
            Dav off
          </IfModule>
        SetEnv HOME /var/www/html/owncloud
        SetEnv HTTP_HOME /var/www/html/owncloud
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined

RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com [OR]
RewriteCond %{SERVER_NAME} =www.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

</VirtualHost>

A new configuration file for the domain should also be created named /etc/apache2/sites-available/owncloud-le-ssl.conf. This is Apache2 SSL module configuration file and should contain the certificate definitions defined in it.

<IfModule mod_ssl.c>
<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/owncloud/
     ServerName example.com
     ServerAlias www.example.com
  
     Alias /owncloud "/var/www/html/owncloud/"

     <Directory /var/www/html/owncloud/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted
          <IfModule mod_dav.c>
            Dav off
          </IfModule>
        SetEnv HOME /var/www/html/owncloud
        SetEnv HTTP_HOME /var/www/html/owncloud
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined

SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf

</VirtualHost>
</IfModule>

Then open your browser and browse to the server domain name followed by install. You should see OwnCloud setup wizard to complete. Please follow the wizard carefully.

https://example.com

You should then see OwnCloud setup page.. Connect to the database using the information you created and continue. Select the database server installed on your systems by clicking it as shown in the image below

Click Finish setup and you’re done.

Enjoy!

Congratulations! You have successfully installed OwnCloud on Ubuntu `17.04 | 17.10 with Let’s Encrypt support.

To setup a process to automatically renew the certificates, add a cron job to execute the renewal process.

sudo crontab -e

Then add the line below and save.

0 1 * * * /usr/bin/certbot renew & > /dev/null

The cron job will attempt to renew 30 days before expiring

Enjoy!
