Centos 6.6 VNC install

Centos 6.6 VNC install

I am having so many problems doing a Windows guest install on my KVM host server, which is headless, I figured I would install Gnome on it and VNC. I have another article on the Gnome install. Please see that article if you don’t have a desktop on your server.

I am doing this on my KVM host server logged in as root

Install VNC packages

# yum install tigervnc-server

# yum install xorg-x11-fonts-Type1

Make sure VNC starts on boot

# chkconfig vncserver on

Now set your VNC password

# vncpasswd 

Now create a connection so the VNC clients can connect to your VNC server

# vi /etc/sysconfig/vncservers

Add the following to the end of the file: **NOTE: Use a regular user account name here, not root user

VNCSERVERS="1:your_user_name_here"

VNCSERVERARGS[1]="-geometry 1024x768" 

If you need to add another user then do so. Make sure you use a different VNCSERVERS= number and the other users name, like

VNCSERVERS="2:another_user_name_here"

VNCSERVERARGS[1]="-geometry 1024x768" 

If you use iptables then do the following to allow VNC traffic

# iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp -m multiport --dports 5901:5903,6001:6003 -j ACCEPT

# service iptables save

# service iptables restart

Now actually start the service

# service vncserver restart

If you get an error like "getpassword error: Inappropriate ioctl for device" then try the following.

Login or ssh to the server as the user and run the “# vncpasswd “ command from the users home dir.

Once you can start the service without an error continue.

# vncserver -kill :1

Now from the users home directory do this to run the Gnome desktop

# vi .vnc/xstartup

Comment the last line and add the “exec gnome-session &” line at the bottom

#twm &

exec gnome-session &

Restart service again

# service vncserver restart

Now put the VNC client on your PC or Linux desktop and connect using:

Name:1 or serverIP:1
