Jack Wallen walks you through the process of installing the latest ownCloud server release onto the latest iteration of Ubuntu Server.

Of late, nextCloud has been given the majority of the spotlight for on-premises cloud servers. However, I want to take a moment to walk you through the installation of the server that started it all. ownCloud is an equally capable cloud server that can meet and exceed your company needs. But installing this platform on the latest release of Ubuntu is a bit different than previous incarnations. So, let's see what happens when we undertake the process of installing the latest version of ownCloud onto the latest version of Ubuntu Server. The process isn't terribly challenging, at least not when you know what dependencies to install.

Let's get busy.

What you'll need

Obviously, you'll need a working instance of Ubuntu Server 18.04. I will assume you have that up and running. I will also assume you installed Ubuntu Server with the standard LAMP package offering—so Apache, MySQL, and PHP will already be up and running. One of the biggest differences between installing ownCloud on Ubuntu 16.04 and 18.04 will be the PHP packages. I'll show you how to get around that hurdle.

You will also need to download the latest version of ownCloud. This can be done with the command wget URL (where URL for the latest downloadable package can be found here). So for version 10.0.8, you'd issue the command:

wget https://download.owncloud.org/community/owncloud-10.0.8.zip

Installing dependencies

The first thing you must do is install the necessary PHP dependencies. As I said before, this can be tricky. You first need to find out what version of PHP is installed on your machine. To do this, issue the command php -v. On my installation of Ubuntu 18.04, the PHP release is PHP 7.2-7-1. The important part is the 7.2. So we need to make sure all of our PHP modules are of the 7.2 flavor. For this, we'll issue the command:

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-apcu php7.2-smbclient php7.2-ldap php7.2-redis php7.2-gd php7.2-xml php7.2-intl php7.2-json php7.2-imagick php7.2-mysql php7.2-cli php7.2-mcrypt php7.2-ldap php7.2-zip php7.2-curl

You may find that some of the above modules cannot be installed. To get around that, simply delete those modules from the above command. For my installation, I had to remove:

  • php7.2-redis
  • php7.2-imagick
  • php7.2-mcrypt
  • php7.2-smbclient

Once those were out of the command line mix, the installation went fine. Just make sure to pay attention to the output of your command and then adjust accordingly.

Configure PHP

Now we need to configure PHP. There are only two options you need to deal with. Issue the command sudo nano /etc/php/7.2/apache2/php.ini and then adjust the following parameters:

  • memory_limit =
  • date.timezone =

The memory_limit option should be no less than 256M and the date.timezone should be set to your location. To find out what timezone you should use (and the format of said timezone), take a look at this site.

Save and close that file. Restart Apache with the command:

sudo systemctl restart apache2

Create the database

Now we need to create the database. To do this, issue the command:

sudo mysql -u root -p

You'll be prompted first for your sudo password and then the MySQL root user password. I add sudo to this command on the off-chance you are using MariaDB (instead of MySQL). Once in the database command prompt, create the database with the command:

CREATE DATABASE owncloud;

Next create a new database user with the command:

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

Where PASSWORD is a strong password for the user.

Give the new user permissions for the new database with the command:

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

Where PASSWORD is a strong password for the user.

Flush the privileges and exit the database shell with the commands:

FLUSH PRIVILEGES;
EXIT;

Unpack and move the ownCloud file

Now we need to unpack and move the ownCloud file and then give it the proper permissions. I'm going to assume you downloaded the file to your home directory. With that in mind, everything can be done with the following commands:

cd ~/
unzip unzip owncloud-*.zip
sudo mv owncloud /var/www/html/
sudo chown -R www-data:www-data /var/www/html/owncloud/
sudo chmod -R 755 /var/www/html/owncloud/

Configure Apache

We now must configure Apache so that it is aware of our new ownCloud site. Create a new conf file with the command:

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

The contents of that file should be:

<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>

Where you see example.com and www.example.com, if you don't need domains (and will be using ownCloud by IP address only), you can comment out these lines.

Save and close that file.

Now we need to enable the site and the necessary modules. These steps are handled with the following commands:

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

NOTE: Some of the above modules may already be enabled.

Restart Apache with the command:

sudo systemctl restart apache2

The final step

At this point, open up a browser and point it to http://SERVER_IP/owncloud. You should be greeted by the ownCloud installer (Figure A), where you only need to create an admin user and enter the information for the database.

Figure A

The browser installer is the last step.


Click Finish setup and ownCloud will take care of everything. You will eventually be prompted to log in with the admin user you just created. Congratulations, you now have a working ownCloud, on-premises cloud server. You can now configure it to meet (and exceed) your company needs.
