Query on NGINX Open Source

Hi All,

I was referred by my colleague about NGINX. So i am new to CentOS and NGINX.

We planned to have these services (Webserver and load-balancer) using NGINX Open Source.

1. I read installation document. It mentioned i can compile Open Source or install Prebuilt Open Source Package. This is the statement "The package includes almost all official NGINX modules". Question is, does it includes Webserver and load-balancer?

2. What is the hardware requirements? CPU, memory and disk space for Webserver and load-balancer?

3. What are the steps, commands i had to enter?

Look forward to your guide to achieve my objective.
