Hello,
Joomla comes with htaccess.txt, and the option to rewrite urls. So you have to first change the htaccess.txt file to .htaccess on the server, then login and in the configuration settings change SEF to on, and use .htaccess to on.
Thanks

i make this steps and after this steps site shows me *500 Internal Server Error*. when i turn off *Use URL Rewriting*, than everything is fine.
