First, make sure that you don?t already have the server-side install. See if /etc/sysconfig/vncservers exists. If it does, the VNC server is already installed.
In this case, you would just add a line like:
VNCSERVERS="1:username"
(?1? is the display to use; ?username? is your username.)
to that file, and do service vncserver restart to restart the VNC server with the new configuration.
If you?re just wanting to use KDE or something other than the default window manager, go to your home directory and edit ~/.vnc/xstartup. Here?s what I have in mine:
#!/bin/sh
xrdb $HOME/.Xresources
startkde &
Then make sure that your client connects to the proper X display.
