Centos6.3 install vnc

1. use yuminstalltigervnc-server to install vnc2 and modify the configuration file [root @ localhost ~] # Cat/etc/sysconfig/vncservers # TheVNCSERVERSvariableisalistofdisplay: userpairs. # Uncommentthelinesbelow 1. use yum install tigervnc-server to install vnc

2. modify the configuration file

[Root @ localhost ~] # Cat/etc/sysconfig/vncservers
# The VNCSERVERS variable is a list of display: user pairs.
#
# Uncomment the lines below to start a VNC server on display: 2
# As my 'myusername' (adjust this to your own). You will also
# Need to set a VNC password; run 'Man vncpasswd' to see how
# To do that.
#
# Do not run this service if your local area network is
# Untrusted! For a secure way of using VNC, see this URL:
# Http://kbase.redhat.com/faq/docs/DOC-7028
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-localhost" to prevent remote VNC clients connecting tables T when
# Doing so through a secure tunnel. See the "-via" option in
# 'Man vncviewer 'manual page.
# VNCSERVERS = "10: myusername"

# VNCSERVERARGS [1] = "-geometry 800x600-nolisten tcp-localhost"

Remove # VNCSERVERS = "10: myusername"

# VNCSERVERARGS [1] = "-geometry 800x600-nolisten tcp-localhost" the "#" before the two statements (that is, remove the comment)

Change myusername to the user name you log on to. set the preceding number. vnc is defined by Port + desktop number,

The vnc port is 5900. here, my desktop number is 10. when connecting to the vnc, the port is 5900 + 10, that is, 5910.

"1" in VNCSERVERARGS [1] indicates that I only open services to one user.

3. set the password

[Root @ localhost ~] # Vncserver

After entering the vncserver, the system prompts you to set the password.
You will require a password to access your tops.
Password:
Verify:
4. restart the service

[Root @ localhost ~] # Service vncserver restart

If prompted

5. we recommend that you add this port to the firewall and set it to a boot entry.

[root@localhost ~]#iptables -I INPUT -p tcp --dport 5901 -j ACCEPT
[root@localhost ~]#Chkconfig vncserver on

6. restart the firewall.

7. test the connection on the client. the ip address of my server is 192.168.7.198, enter 192.168.7.198: 10 on the client, and the password is the password set in step 3.
