If you selected it when you installed Fedora it is :-)
If the httpd rpm is installed, you have apache.
You xcan check it with:
rpm -qa | grep httpd
if it is installed, su to root and type
/etc/init.d/httpd start
open a browser and surf to
http://127.0.0.1
If you see a welcome page, you have aworking webserver.
Then you should start redaing the manual on the apache website. It should be useless to include it in this post :-)
