1、首先安裝vnc的伺服器端

        yum install tigervnc-server

2、啟動vnc服務

       執行vncserver或者service vncserver start

       New 'was1.com:1 (root)' desktop is was1.com:1

       Starting applications specified in /root/.vnc/xstartup
       Log file is /root/.vnc/was1.com:1.log

       設定遠端登入密碼，不要使用小鍵盤，在vncpasswd下小鍵盤的作用相當於上下左右，沒有數字功能，切記

3、修改/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:
    #

    # Use "-nolisten tcp" to prevent X connections to your VNC server via TCP. 

    # Use "-localhost" to prevent remote VNC clients connecting except when
    # doing so through a secure tunnel.  See the "-via" option in the
    # `man vncviewer' manual page.

    # VNCSERVERS="2:myusername"

     # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

     VNCSERVERS="1:root 2:test"
     VNCSERVERARGS[2]="-geometry 800x600"

可以複製

    # VNCSERVERS="2:myusername"

     # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

這兩行配置進行修改。其中geometry 800x600 意思為以800*600的解析度遠端桌面 ；nolisten tcp 不偵聽tcp localhost為只允許本地主機連線

修改配置完重啟服務service vncserver restart

4、在客戶端安裝vnc

windows使用者可直接下載安裝vnc

linux需要安裝tigervnc

vncviewer [email protected]伺服器地址：1或者2

5、在伺服器上設定vncserver開機自啟動

chkconf  vncserver on

6最後一點：開通vnc的伺服器一定要設定防火牆，關閉防火牆。。。
