I have text installed CentOS 5.2 using the first CD only or a minimal install without the server packages. My question is that if i run install.sh right away will the script pull/download all the necessary packages in order for it to run? Or do i have to manually install individual packages.
We strongly recommend you not pre-install any packages (though packages installed from the standard OS sources shouldn’t cause problems; packages from third party sources almost definitely will). A minimal OS install is the best possible place to start, and is recommended by the documentation.
