CentOS 6.4 – installation VNC server

First, install VNC
By default, CentOS 6.4 is not installed.
Check whether the installation, enter:
[Root @ localhost ~] # rpm -q vnc vnc-server
package vnc is not installed
Tip is not installed, then start the installation, enter:
[Root @ localhost ~] # yum install vnc vnc-server

Second, set the VNC password

After installation is complete early start VNC otherwise need to perform the first step will be reported Centos still not installed VNC

[Root @ localhost ~] $ vncserver
Set VNC password, enter 🙁 in a user enter the login user is under it, if su imiss switch to imiss user input vncserver is started is another desktop also have to set a password, after the start of vncserver under the account login you need the password for this user set under a.)
At this point you will be prompted to enter a password, because it is the first time configuration. Re-enter twice.
[Root @ localhost ~] $ vncpasswd

Third, configure desktop type

[Root @ localhost ~] $ vi ~ / .vnc / xstartup
Under normal circumstances, we use Linux desktops are “Gnome” desktop, so the desktop is configured to compare this habit.
Press the “i” key to enter the edit mode, the main change the last two lines. Read:
# Xterm -geometry 80×24 + 10 + 10 -ls -title “$ VNCDESKTOP Desktop” &
# Twm &
gnome-session &

Key edit the last two lines, the two lines uncommented get:

Fourth, configure the login account, desktop resolution, connection
[Root @ localhost ~] # vi / etc / sysconfig / vncservers

Modify the last two lines

VNCSERVERS = “1: root”
VNCSERVERARGS [1] = “- geometry 1024×768”

Fifth, configure the firewall to allow VNC connections
VNC server listening port from the beginning of 5900, display: 5901 1 monitor, display: 2 monitor 5902, and so on. CentOS firewall default is not allowed to connect to these ports, so you need to use the following steps to open the firewall (requires root privileges):
Input Editor:
[Root @ localhost ~] # vi / etc / sysconfig / iptables

Above, we just added a root account and desktop 1, so here follow the above rules, add a “5901” port number.

-A INPUT -m state –state NEW -m tcp -p tcp –dport 5901 -j ACCEPT

Sixth, reboot the firewall

service iptables restart

Seven, set to start automatically VNC

[Root @ localhost ~] # chkconfig vncserver on

Eight close
vncserver -kill: 1 (note that there is a space behind kill)

Successful installation

Nine, the client installation

Download and install vnc viewer

After a successful installation Login

Then it will pop up a password, the password you just set password.

Password not login account password set but vnc
