Deploy VNC Server in CentOS6

Deploy VNC Server in CentOS6

VNC (Virtual Network Computer) is short for Virtual Network Computer. VNC is a free open-source software based on UNIX and Linux operating systems. It has powerful remote control capabilities and is highly efficient and practical. Its performance can be comparable to any remote control software in Windows and MAC.

In Linux, VNC includes the following commands: vncserver, vncviewer, vncpasswd, and vncconnect.

The following uses CentOS6.2 as an example. The procedure for installing VNC is as follows:

1. Install gnome Desktop Environment

If the gnome desktop environment has been installed on the system, skip this step.

# Install fontforge to avoid box garbled characters in the font.

Yum install fontforge-y

# Install gnome Desktop Environment

Yum groupinstall Desktop-y

# Install the Chinese Language Support Package

Yum groupinstall 'Chinese Support '-y

# Set the default system language to Chinese

Sed-I '/LANG/c \ LANG = "zh_CN.UTF-8"'/etc/sysconfig/i18n

Source/etc/sysconfig/i18n

2. Deploy the vnc server

# Install the vnc software package

Yum install tigervnc-server-y

# Set vncserver startup

Chkconfig vncserver on

# Set the vnc logon password. Save the password in ~ /. Vnc/passwd

# If you want to change the vnc password of a common user, su must switch to this user first.

Vncpasswd

# Viewing the vncserver configuration file

Rpm-qc tigervnc-server

# Configuring vncserver

Vim/etc/sysconfig/vncservers

# Start the first and second desktops as root users

VNCSERVERS = "1: root 2: root"

# Adjust resolution

VNCSERVERARGS [1] = "-geometry 1024x768"

VNCSERVERARGS [2] = "-geometry 1024x768"

# Start vncserver. The following two desktops are started:

Vncserver: 1

Vncserver: 2

# Modify the xstartup file and change the last twm & to gnome-session &

# This file appears only after vncserver is started. After modification, restart vncserver.

Vim ~ /. Vnc/xstartup

# Stop vncserver

Vncserver-kill: 1

Vncserver-kill: 2

# Configuring a firewall

Iptables-I INPUT-m state -- state NEW-m tcp-p tcp -- dport 5901-j ACCEPT

Iptables-I INPUT-m state -- state NEW-m tcp-p tcp -- dport 5902-j ACCEPT

Service iptables save

Now that the server is deployed, you can access the Remote Desktop through UltraVNC Viewer, TigerVNC Viewer, or RealVNC Viewer.

The following describes common operations:

# Batch start

Service vncserver start

# Batch restart

Service vncserver restart

# Batch stop

Service vncserver stop

# View the running Desktop

Vncserver-list
