Install Nextcloud in Ubuntu

Nextcloud – cloud platform for storing files, a branch of the project OwnCloud.

On the test, I will install the latest version of Nextcloud in Ubuntu Server 16.04 LTS (at the time of this writing was 12).
First of all, we will install the necessary components:

sudo apt-get update
sudo apt-get install apache2 mysql-server php libapache2-mod-php php-json php-mcrypt php-mysql php-bz2 php-curl php-gd php-imagick php-intl php-mbstring php-xml php-zip php-memcache

Activate the necessary apache2 modules:

sudo a2enmod rewrite
sudo a2enmod headers
sudo a2enmod env
sudo a2enmod dir
sudo a2enmod mime
sudo a2enmod setenvif
sudo a2enmod ssl

And restart it to apply the changes:

sudo service apache2 restart

Download Nextcloud:

cd ~
wget --no-check-certificate https://download.nextcloud.com/server/releases/latest.tar.bz2

You can verify the checksums MD5 or SHA256 to make sure that the archive is not damaged:

wget --no-check-certificate https://download.nextcloud.com/server/releases/latest.tar.bz2.md5
wget --no-check-certificate https://download.nextcloud.com/server/releases/latest.tar.bz2.sha256
md5sum -c latest.tar.bz2.md5 < latest.tar.bz2
sha256sum -c latest.tar.bz2.sha256 < latest.tar.bz2

Unzip the archive into the web server directory, set permissions and delete it:

sudo tar -C /var/www -xvjf ~/latest.tar.bz2
sudo chown -R www-data:www-data /var/www/nextcloud/
rm ~/latest.tar.bz2
rm ~/latest.tar.bz2.md5
rm ~/latest.tar.bz2.sha256

Create a web configuration file (in the nano editor, press Ctrl+X to exit, y/n to save or cancel changes):

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

And add to it:

Alias /nextcloud "/var/www/nextcloud/"
<Directory /var/www/nextcloud/>
  Options +FollowSymlinks
  AllowOverride All

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

 SetEnv HOME /var/www/nextcloud
 SetEnv HTTP_HOME /var/www/nextcloud
</Directory>

We activate the configuration as follows:

sudo a2ensite nextcloud

or so:

sudo ln -s /etc/apache2/sites-available/nextcloud.conf /etc/apache2/sites-enabled/nextcloud.conf

Restart apache2:

sudo service apache2 restart

Create mysql user and database:

mysqladmin -u root -p create nextcloud
mysql -u root -p -e "GRANT ALL PRIVILEGES ON nextcloud.* TO nextcloud@localhost IDENTIFIED BY 'PASSWORD';"
mysql -u root -p -e "flush privileges;"

Open in browser http://HOST/nextcloud/ specify the data and click “Finish installation”.
Standard directory for storing user files /var/www/nextcloud/data.

In the PHP configuration /etc/php5/apache2/php.ini specify date.timezone, other parameters are already specified in the file /var/www/nextcloud/.htaccess
Also, for secure transmission of data, I recommend that you configure SSL.
In the settings nextcloud, in the “Administration” menu you can see additional recommendations for customization.

Nextcloud installation completed.
