I have standard Ubuntu 16.04 droplet over digitalocean with LAMP stack. By default I have one user with root privileges (for admin use). I access any directory from root through ssh like with filezilla or netbeans. It all works fine as it should upto this.
I need more users created so that I can configure them to be able to access a particular vhost directory say like /var/www/html/domain2.com
or probably only /var/www/html/*
Also I need to be sure that doing so will not affect any Apache related permissions on folders and files. Say if I create a folder say uploads from user1 and www-data user cant read or write into that folder uploads.
How can I do this ?
