It's a good idea to get/download the server admin manual and server vm manual from VMWare, they cover a lot of this stuff.
To install the tools on a Linux guest, you need to use the server console or a client console, with the particular guest os vm displayed, and the guest os running. Select Install VMWare Tools from the top menu.
On a Windows guest os, the installer usually starts automatically, on a Linux guest, nothing appears to happen. i.e. it must be done manually.
All it does is make a CD image available to mount.
Mount the CD image
mount /dev/cdrom /mnt/cdrom
move to something like /tmp
and yhave a look at the image
There will be an RPM and a tar.gz file in the image, called something like
extract this to /tmp
tar zxf VMwareTools-1.0.4-XXXXX.tar.gz
unmount the cd image
and have a look
There will be a vmware-tools-distrib or similar folder created, cd into it and run the installer
