Redhat as 5 vncserver及vncviewer的详细配置
1、 首先要配置的是服务端
A 确认服务器端是否安装了vncserver
使用rpm –qa vnc命令如果收到如下信息说明已经安装了vncserver,
[root@localhost: ~]#rpm -qa |grep vnc
gtk-vnc-python--3.el5
vnc-server--14.el5
gtk-vnc--3.el5
vnc--14.el5
B从光盘找到安装包进行安装
首先将光盘挂载(也叫解压)到某个目录这里是在/var/ftp/pub/下面建立了rhel5-64目录
mount –o loop rhel-server-5.3-x86_64-dvd.iso /var/ftp/pub/rhel5-64/
然后在/var/ftp/pub/rhel5-64/Server目录下找到 vnc-server--14.el5.x86_64.rpm安装包,使用rpm –ivh vnc-server-4.1.2-14.el5.x86_64.rpm命令直接安装;
C 接下来就是最重要的配置步骤了:
服务器端配置如下:
1)第一次启动vncserver 会提示输入密码:
管理员帐户:
[root@localhost /]# vncserver
You will require a password to access your desktops.
Password: 输入vnc 连接密码
Verify: 确认vnc密码
xauth: creating new authority file /root/.Xauthority
New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.localdomain:1.log
普通用户:
[root@localhost /]#su huilin
[huilin@localhost /]$ vncserver
You will require a password to access your desktops.
Password: 输入vnc 连接密码
Verify: 确认vnc密码
xauth: creating new authority file /home/huilin/.Xauthority
New 'localhost.localdomain:2 (huilin)' desktop is localhost.localdomain:2
Creating default startup script /home/huilin/.vnc/xstartup
Starting applications specified in /home/huilin/.vnc/xstartup
Log file is /home/huilin/.vnc/localhost.localdomain:2.log
* 注意到每个用户都可以启动自己的 vncserver,每个用户可以启动多个 vncserver,
用ip加端口号 ip:1,ip:2,ip:3 来标识。vncserver的大部分配置文件及日志文件都在用户home目录下.vnc目录下
用户可以自定义启动号码如:
[huilin@localhost /]$ :A VNC server is already running as :2
2)配置vnc的配置文件xstartup文件
如果用的是gnome 桌面环境还需要修改
[root@localhost .vnc]# vi xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER 将此行的注释去掉
# exec /etc/X11/xinit/xinitrc 将此行的注释去掉
[ -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 gnome 添加连接时使用 gnome 桌面环境
twm &
3)在的信息
[root@localhost: ~]#vi /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
# URL:
# 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. See the "-via" option in the
# `man vncviewer' manual page.
VNCSERVERS="1:root 2:demo" 此处添加用户
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
#vncserver -geometry 800x600 设置vncserver的分辨率
#vncserver -geometry 640x480 设置vncserver的分辨率
#vncserver -depth 8 设置vncserver的色深
#vncserver -depth 16 设置vncserver的色深
4)客户端的连接
a、在linux下,运行vncviewer命令即可,服务器地址的写法形如192.168.3.119:1
b、在windows下,运行即可,用法与linux下相近。
c、用浏览器(平台无关),作为java applet来实现,以形如的方式来启动 (vnc 端口从5800 开始依次类推,一般会是5800,5900)
5)修改密码
运行vncpasswd即可
6)停止vncserver
#vncserver -kill :1
#vncserver -kill :2
注意到vncserver只能由启动它的用户来关闭,即时是root也不能关闭其它用户开启的vncserver,
除非用kill命令暴力杀死进程。
7)稳定性设置
vncserver默认在多个客户机连接同一个vncserver的显示端口时,vncserver端口旧连接,而为新连接服务,可通过-dontdisconnect拒绝新连接请求而保持旧的连接。
8)同一个显示器可以连接多个客户机
#vncserver –alwaysshared
