installing nginx on centos should be straightforward

I have set up a virtual server with a LAMP stack (Centos 6.3) and am now trying to install nginx to use as a proxy server. I have been told to download from sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm and have done so prior to trying to install nginx. However, something was wrong with this because when I tried to install nginx (sudo yum install nginx), there were a number of packages that were skipped due to dependency problems. When I tried to start nginx, it could not find the files.

Given that nginx is a well-used server, this has to be easier than what I am encountering. Does anyone know the correct commands to set this up so that nginx can install?

Thanks.
