The RPM version of the VMware tools installer for Linux guests seems to have gone the way of the dinosaur. In addition, the tools ISO for Linux has been provided as it’s own download, that is hidden away on the ESX or ESXi download pages, rather than the “Tools and Drivers” page.
Not sure why, but “Tools and Drivers” seems like an obvious choice to me.
It probably has to do with the move to VMware Tools Operating System Specific Packages (OSPs) – in the case of RHEL/OEL/Centos, it’s a yum repository you add in /etc/yum.repos.d that will grab the latest packages for your specific OS.
