Owncloud not found

Hi there.
I wanted to install owncloud on my VPS, so I installed LAMP firstly and it’s working (“Congratulations. LAMP is installed successfully!”)

I installed all the files (for CentOS) which were presented on this page:
Then I restarted Apache and created database owncloud.

But When I tried to open owncloud, it comes to a error just like:

Not Found
The requested URL /owncloud was not found on this server.

I tried to install owncloud again but it was told that
" Package owncloud-files-10.0.10-1.1.noarch already installed and latest version
Nothing to do."

Appreciate for every tip:)


maybe you first need an web server configuration file like shown in e.g. the documentation below telling your web server where to look for the ownCloud files?
