Installation and use of the VNC remote desktop program in Centos

This article illustrates the installation and use of the VNC remote desktop application in Centos. I will share it with you for your reference as follows:

Take centos 6.5 for example

Install the GNOME desktop environment

yum groupinstall "X Window System" "Desktop"

CentOS install Xfce desktop environment, optional

yum groupinstall Xfce

Install tigervnc

yum install tigervnc-server tigervnc

Set the configuration of remote login to gnome desktop and add the following two lines at the end:

vim /etc/sysconfig/vncservers

VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768 -alwaysshared -depth 24"

Modify the remote desktop display profile: change it to the following and save it

vim /root/.vnc/xstartup

#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
gnome-session & #set starting GNOME desktop
#startkde & #kde desktop
#twm & #Text interface
#/usr/bin/startxfce4
#exec /usr/bin/fluxbox

Create a new service, execute for many times, then build multiple services, in order :1 :2 :3, every time you start, you will be prompted to set a password

vncserver

Turn off the specific vncserver command

vncserver -kill :1
vncserver -kill :2

Powered up

chkconfig vncserver on

Firewall setup

When you start the vnc service, you can use the netstat, tunlp command to view the ports used by the vnc service. You can find 5801,5901,6001, etc. Open these ports with the following command:
Restart the firewall:

# netstat  � tunlp
Proto Recv-Q Send-Q Local Address    Foreign Address    State  PID/Program name
tcp  0  0 0.0.0.0:5901    0.0.0.0:*     LISTEN  2092/Xvnc
tcp  0  0 0.0.0.0:111     0.0.0.0:*     LISTEN  1459/rpcbind
tcp  0  0 0.0.0.0:6001    0.0.0.0:*     LISTEN  2092/Xvnc
tcp  0  0 0.0.0.0:22     0.0.0.0:*     LISTEN  1711/sshd
tcp  0  0 127.0.0.1:631    0.0.0.0:*     LISTEN  1557/cupsd
# vim /etc/sysconfig/iptables
-A RH-Firewall-l-INPUT -p tcp -m tcp  � dport 5801 -j ACCEPT
-A RH-Firewall-l-INPUT -p tcp -m tcp  � dport 5901 -j ACCEPT
-A RH-Firewall-l-INPUT -p tcp -m tcp  � dport 6001 -j ACCEPT
# /etc/init.d/iptables restart

Install Windows client:

http://sourceforge.net/projects/tigervnc/files/latest/download

Start the TrigerVNC Viewer

Enter the server IP:01, for example: 192.168.1.10:1

Once connected, enter the password you set every time you start vncserver to connect to the centos desktop

I hope this article has helped you with your CentOS server operations.
