After that, move into NextCloud.

linuxhelp opt # mv nextcloud /var/www/html/

And switch directory.

linuxhelp opt # cd /var/www/html/nextcloud/

And then change ownership with the help of the following command.

linuxhelp nextcloud # chown -R www-data.www-data /var/www/html/nextcloud/
linuxhelp nextcloud # ls -ld .
drwxr-xr-x 14 www-data www-data 4096 May 22  2017 .
linuxhelp next cloud # cd ../
linuxhelp html # cd

Once it is done, you need to create a .conf file to configure the VirtualHost.

linuxhelp ~ # vim /etc/apache2/sites-available/nextcloud.conf

Add the following lines in the file.

< virtualhost *:80> 
ServerName  linuxhelp.nextcloud.io
Documentroot /var/www/html/nextcloud
< /virtualhost> 

Once it is done, you need to restart Apache service

linuxhelp ~ # systemctl restart apache2

And then, you need to create a link for virtual host

linuxhelp ~ # ln -s /etc/apache2/sites-available/nextcloud.conf /etc/apache2/sites-enabled/nextcloud.conf

linuxhelp ~ # a2enmod rewrite
Enabling module rewrite.
