Environment: REDHAT 5
1. Check if VNC is installed:
Rpm-qa Vnc-server
Vnc-server-4.1.2-9.el5
if not installed, install:
Yum Install Vnc-server
2. Configure the Vncserver login password:
[Email protected] ~]# Vncserver
You'll require a password to access your desktops.
Password:
Verify:
Xauth:creating new Authority file/root/. Xauthority
New ' redhat:1 (root) ' Desktop is redhat:1
Creating default startup Script/root/.vnc/xstartup
Starting applications specified In/root/.vnc/xstartup
Log file Is/root/.vnc/redhat:1.log
3. Configure the Vncserver boot file:
VI ~/.vnc/xstartup
Modified file:
#!/bin/sh
# Uncomment the following-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" &
# TWM &
Gnome-session &
4. Configuring the Vncservers File
Vi/etc/sysconfig/vncservers
Modified file:
# 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'll also
# need to set a VNC password; Run ' man vncpasswd ' to see how
# to does that.
#
# do not RUN the this SERVICE if your the local area network is
# untrusted! For a secure-to-the-using VNC, see
# <url:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.
# use "-nolisten TCP" to prevent X connections to your VNC server via TCP.
# Use the "-nohttpd" to prevent web-based VNC clients connecting.
# 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-nohttpd-localhost"
Vncservers= "1:root"
vncserverargs[1]= "-geometry 1024x768-nolisten tcp-nohttpd-localhost"
5. Turn off the firewall
Service Iptables Stop
or open VNC port:
/sbin/iptables-i input-p TCP--dport 5801-j ACCEPT
/sbin/iptables-i input-p TCP--dport 5900:5903-j ACCEPT
/etc/rc.d/init.d/iptables Save
/etc/init.d/iptables restart
6. Kill the current process:
Vncserver-kill:1
Vncserver-kill:2
...
7. Start Vncserver
[Email protected] ~]# Vncserver
New ' redhat:1 (root) ' Desktop is redhat:1
Starting applications specified In/root/.vnc/xstartup
Log file Is/root/.vnc/redhat:1.log
8. Connect via browser (JAVA):
http://192.168.65.131:5801/
9. Connect via the VNC Viewer client:
192.168.65.131:1
Follow the prompts to enter the previously configured login password to open!
PS: Problems that may occur:
A, black screen
Installed in Linux in the configuration of the VNC server, the discovery of multi-user login will appear black screen situation, the specific phenomenon is:
The client can enter the system via IP to the session number, but landing in is dark, except for a forked mouse, pitch.
Cause: The user's VNC startup file permissions are not set correctly.
Workaround: Modify the properties of the black screen user's Xstartup (typically:/home/user name/.vnc/xstartup) file to 755 (rwxr-xr-x).
B, VNC can enter a number, but cannot enter the letter
Reason: VNC server will require VNC viewer this side of the OS's input method to be the same as the VNC Server OS language.
Workaround: Generally we install the Linux OS are e-text, so when using the VNC Viewer connection, please close the local OS Chinese input method, switch to English can be.
