VNC server configuration on RHEL 6

Step 1

Installing  the VNC Server.

Download the following rpms and install/update them 

#rpm –ivh tigervnc-license-1.3.1-17.el6.noarch.rpm   

#rpm -Uvh libjpeg-6b-46.1.x86_64.rpm   

#rpm -Uvh libjpeg-turbo-1.2.1-1.el6.x86_64.rpm

#rpm -ivh tigervnc-server-minimal-1.3.1-17.el6.x86_64.rpm

#rpm -ivh tigervnc-server-1.3.1-17.el6.x86_64.rpm

Step 2

Edit the "/etc/sysconfig/vncservers" file to configure the required displays. The following entries enable VNC for display numbers ":2" and ":3". Notice multiple "display:user" pairs are defined on a single line, but the arguments for each display are defined separately.

vi  /etc/sysconfig/vncservers  

add the following lines

VNCSERVERS="2:root 3:oracle"

VNCSERVERARGS[2]="-geometry 1280x1024 -nolisten tcp -localhost"

VNCSERVERARGS[3]="-geometry 1280x1024"

Step 3

Set the VNC password for any users defined in the "/etc/sysconfig/vncservers" file.

# vncpasswd

Password:

Verify:

#

# su - oracle

$ vncpasswd

Password:

Verify:

$ exit

logout

# 

Step 4

Enable the "vncserver" service for autostart and start the service.

# chkconfig vncserver --list

vncserver       0:off   1:off   2:off   3:off   4:off   5:off   6:off

# chkconfig vncserver on

# chkconfig vncserver --list

vncserver       0:off   1:off   2:on    3:on    4:on    5:on    6:off

# service vncserver start
