You should check line 15 of /etc/apache2/sites-enabled/owncloud.conf for typos.

I got it.

Thanks for this tutorial

Hi Shawn,

If you have Debian 9 installed, then PHP 7.0 is the default version of PHP distributed with the OS. If you need a newer PHP version you will have to add some unofficial repository.

I am new to Linux but from what I understand Owncloud no longer supports anything below 7.2.

you have made an error somewhere during the installation, please try again with the steps we have provided

It seems that you are trying to connect to your database server as user root.

When you are configuring the database connection in the “Configure the database” section from your browser, make sure that you enter the exact same database information as you did when creating the database in Step 2 of the tutorial.

Error while trying to create admin user: Failed to connect to the database: An exception occured in driver: SQLSTATE[HY000] [1698] Access denied for user ‘root’@’localhost’

But, with SQLite, I can pass Admin Create task.

How can I use MySQL/MariaDB?

sudo apt install apache2 mariadb-server libapache2-mod-php7.0 \
openssl php-imagick php7.0-common php7.0-curl php7.0-gd \
php7.0-imap php7.0-intl php7.0-json php7.0-ldap php7.0-mbstring \
php7.0-mcrypt php7.0-mysql php7.0-pgsql php-smbclient php-ssh2 \
php7.0-sqlite3 php7.0-xml php7.0-zip php-redis php-apcu

You need install the version 7.2 than is the more current version.

If you want to use HTTPS, you need to purchase or generate a free SSL certificate for your domain and configure Apache with the new SSL certificate.
For more information, you can check the OwnCloud official documentation.

IP of application is the IP of the virtual machine.

To find out on debian, you can install net-tools: sudo apt-get install net-tools
Then you can use the command “ifconfig” (as root) to get your ip-adress.

I installed everything correctly, but what is the IP of the application?
I installed it on a virtual machine.
Localhost does not work.

If you want to access and manage your MySQL databases from your browser, you would have to install phpMyAdmin or some other database management tool on your server.
