Configuring VNC Server on Linux 6.3
Posted by Kashif Manzoor on 10th December 2013
This method applies to RHEL; let’s first install the VNC Server.
Through yum command
# yum install tigervnc-server
Or
Through RPM command
First, locate and mount your RHEL 6.3 install media.
[root@oraerp ~]# cd “/media/RHEL_6.3 x86_64 Disc 1/Packages”
[root@oraerp Packages]# pwd
/media/RHEL_6.3 x86_64 Disc 1/Packages
Install following rpm packages
rpm -ivh xorg-x11-fonts-misc-7.2-9.1.el6.noarch.rpm
rpm –ivh tigervnc-server-1.0.90-0.17.20110314svn4359.el6.x86_64.rpm
Now lets edit the vncservers file to configure display
/etc/sysconfig/vncservers
We can assign numbers to VNC for display like “:2” and “:3”.
In vncservers file we will find “display:user” pairs as defined on a single line.
VNCSERVERS=”2:root 3:oracle”
VNCSERVERARGS[2]=”-geometry 800×600 -nolisten tcp -localhost”
VNCSERVERARGS[3]=”-geometry 800×600″
After this we will set the VNC password for users defined in the “/etc/sysconfig/vncservers” file.
# vncpasswd
Password:
Verify:
#
Lets switch to oracle user and set the password
# su – oracle
$ vncpasswd
Password:
Verify:
$ exit
logout
#
After setting up password, will enable the “vncserver” service for autostart and then start the service.
# chkconfig vncserver on
# service vncserver start
Our setup is over 🙂 now we can use a VNC viewer to connect to server by using the display numbers and passwords defined in our setup.

Faced issue on Oracle Linux 6.4, after configuring vncserver properly was not able to connect…. after research were able to fix the issue…… here is what i did:
Linux Firewall was stopping to connect so i just disabled through this command service iptables stop
[root]# service vncserver status
Xvnc (pid 4370 4174) is running…
[root@]# service iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
