Create NextCloud Database

  1. First, create a Blank Database. Login to the MariaDB Database.

    # sudo mysql -u root -p
  2. Create a Database named nextcloud_db;

    # CREATE DATABASE nextcloud_db;
  3. Create a User for the Database nextcloud_db.

    CREATE USER 'nextcloud_user'@'localhost' IDENTIFIED BY 'your_password';
  4. Grant All privileges for the nextcloud_user to nextcloud_db database.

    #GRANT ALL ON nextcloud_db.* TO 'nextcloud_user'@'localhost' IDENTIFIED BY 'user_password' WITH GRANT OPTION;
  5. Save the changes with the below command.

    # EXIT;

Download Nextcloud Latest Release :

  1. Before installing Nextcloud, we will need to install curl and composer on the server. You can do it with the below command.

    # sudo apt install curl git
    # curl -sS | sudo php -- --install-dir=/usr/local/bin --filename=composer
  2. Download the Nextcloud from Github using below command. We will download it on the apache root directory.
    # cd /var/www/html
    # sudo git clone --branch stable13 nextcloud
    # cd /var/www/html/nextcloud
    # sudo composer install
    # sudo git submodule update --init
  •                Set permission for the folder as below.

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

Configure Apache service

  1. Now, we will need to configure the Apache for Nextcloud. Create a file called nextcloud.conf and add the below content into it.

    # sudo nano /etc/apache2/sites-available/nextcloud.conf 
      ServerAdmin [email protected]
         DocumentRoot /var/www/html/nextcloud/
         Alias /nextcloud "/var/www/html/nextcloud/"
            Options +FollowSymlinks
            AllowOverride All
            Require all granted
                Dav off
            SetEnv HOME /var/www/html/nextcloud
            SetEnv HTTP_HOME /var/www/html/nextcloud
         ErrorLog ${APACHE_LOG_DIR}/error.log
         CustomLog ${APACHE_LOG_DIR}/access.log combined
  2. Save and exit from file.

  3. Enable NextCloud and Rewrite Module.

  4. As we have configured the virtualhost, we will need to enable it with below command.

    sudo a2ensite nextcloud.conf
    sudo a2enmod rewrite
    sudo a2enmod headers
    sudo a2enmod env
    sudo a2enmod dir
    sudo a2enmod mime
  5. Finally, Restart the Apache.

    # sudo systemctl restart apache2.service
  6. Our setup is completed now. Let us check with accessing your domain name in a browser which you have added in nextcloud.conf

  7. Set Nextcloud username, password, data folder and DB username, DB Name. Finally, click on Finish Button.

  8. Here it is. We have Nextcloud Dashboard as per the below image.

        This is it. We are done with Nextcloud installation.
