VNC相关命令:vncconfig
1.检查vnc客户端(tscleint/vncviewer)和服务器是否已经安装在你的系统中
# rpm -qa|grep vnc
vnc-4.1.2-14.el5_3.1
vnc-server-4.1.2-14.el5_3.1
如果没有安装vncviewer,那么运行:
# yum install vnc
客户端我们也可以使用tscleint。
2.配置vncserver
vim /etc/sysconfig/vncservers
增加:VNCSERVERS="1:root"
3.vncpasswd创建一个vnc的口令
注意这将同时在你的home目录下,创建一个隐藏的目录.vnc,其中有一个文件passwd保存着你的vnc口令.
4. #service vncserver start
5. # vncserver (第一次启动时,需要指定一个密码)
You will require a password to access your desktops.
Password:
Verify:
New 'lpi:1 (root)' desktop is lpi:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/lpi:1.log
可以以多个用户身份,启动多个VNC,共享多个用户的桌面:
# lsof -i:{5901,5904}
COMMAND
Xvnc
Xvnc
可以手工指定display#,例如:
# vncserver :99
New 'lpi.123.com:99 (root)' desktop is server01.123.com:99
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/server01.123.com:99.log
6.停止 vncserver(vncserver -kill :display#):
# vncserver -kill :1
Killing Xvnc process ID 2373
7.设置自动运行:ntsysv
8.VNC给浏览器的端口是5800+N,给vncviewer的端口是5900+N,N是设置的display号
http://192.168.1.1:5801/
ultravnc:192.168.1.1:5901
# lsof -i:5801,5901
COMMAND
Xvnc
Xvnc
9.修改VNC密码
# vncpasswd /root/.vnc/passwd
Password:
Verify:
VNC日志文件位于:$HOME/.vnc下的log文件,此目录也包含了一个VNC的xstartup启动文件。
以GNOME方式显示,修改xstartup文件
#!/bin/sh
# Uncomment the following two 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" &
gnome-session &
# tsclient
出现错误:unable to connect to host: Connection refused (111)
一般是没有指定连接的display#,例如地址输入:192.168.1.1出错,192.168.1.1:1就正确了
启动vncserver服务时,出现no displays configured :此错误,请编辑vncservers文件
#vim /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).
# 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!
# <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 "-nohttpd" to prevent web-based VNC clients connecting.
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.
# `man vncviewer' manual page.
VNCSERVERS="1:root"
