Enabling VNC Access to Linux
While setting up my Linux VM in CaaS, I thought I'd share how I enabled VNC access.
I did this on CentOS 5.3. Should work the same for RHEL 5.3 too.
1) When SSHing into your VM, port forward 5901 for VNC access:
ssh -L5901:localhost:5901 root@your.host.emccis.com
2) Configure the VNC server
vi /etc/sysconfig/vncservers
VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768 -nohttpd -localhost"
3) Set up your VNC password
vncpasswd
4) If you want a full gnome session, change your startup
vi ~/.vnc/xstartup
(remove all commands and replace with
gnome-session)
5) Start the VNC server
service vncserver restart
6) Make VNC start at boot
chkconfig vncserver on
7) on your local system, connect to the VNC server
vncviewer localhost:5901
