I use CentOS 5.5 and Apache Webserver on my dedicated Server. My Folder "/var/www/myWebApp" is owned by apache, so that apache can read, write logs, etc..

But now I would like to use very secure FTP (vsftp) to upload my new files. I used to give every user rwx -Acess to "/var/www/myWebApp", but I guess this is way to insecure.

On CentOS I created another user "ftpuser" for uploading files and that has "/var/www/myWebApp" as its home directory. How can I give him the permission to write into the "/var/www/myWebApp" without giving every user the same rights?
