VNC服务是Linux系统经常使用的一种服务，配置起来也不复杂，以下为详细配置方法：

第一步：设置密码

[root@ www.linuxidc.com ~]# vncpasswd

password:

Verify:

第二步：启动一个vncserver session

[root@ www.linuxidc.com ~]# vncserver

这个时候会创建一个/root/.vnc/xstartup文件

第三步：修改生成的xstartup文件，注意粗体字

[root@ www.linuxidc.com ~]# vi /root/.vnc/xstartup

#!/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 &

.......

第四步：修改系统vacserver服务配置

[root@ www.linuxidc.com ~]# vi /etc/sysconfig/vncservers

打开文件后添加以下内容：

VNCSERVERS="1:root"

VNCSERVERARGS[1]=”-geometry 800×600 -alwaysshared -depth 24″

-alwaysshared代表允许多用户同时登录 -depth代为色深，参数有8,16,24,32。

第五步：重启vncserver

[root@ www.linuxidc.com ~]# /etc/init.d/vncserver restart 或 start 或 stop

自己整理

安裝條件：

1，安裝vncserver。

2，安裝xwindows(若不裝，無法使用xwindows的遠程桌面)

配置

打开配置文件/etc/sysconfig/vncservers，去掉下面这行的注释，

注釋掉： # VNCSERVERS="1:myusername"

加入：     VNCSERVERS="1:root"

注釋掉： # VNCSERVERARGS[1]="-geometry 800x600"

2. 停止vnc

终端执行:vncserver -kill :1

后面的：n代表启动的桌面

3. 修改vnc密码

终端执行：vncpasswd

然后连续输入两次密码即可

4.修改下面配置完成界面化的实现...

vi /root/.vnc/xstartup 去除注释下面兩行的注釋，使之生效。

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

最後一行修改為：gnome-session &

6. 如何使得linux启动时，vnc服务自动启动...

a. 系统设置>服务器设置>服务 中把 vncserver 打勾

b. chkconfig vncserver on

room根用户登录在/root目录下

#rpm -q vnc vnc-server查询已安装vnc的客户端和服务器端

vnc-4.1.1-36

vnc-server-4.1.1-36

#vi /etc/sysconfig/vncservers将fangfang用户名加入vncservers文件中

如下所示：

# VNCSERVERS="2:myusername"

VNCSERVERS="2:fangfang"

创建一个vnc的口令

#vncpasswd

Password:

Verify:

启动vnc服务

#sudo /sbin/service vncserver start

Starting VNC server:2:fangfang [FAILED]

后来改为用户fangfang,并在/home/fangfang目录下创建vnc的口令

[fangfang@fangfang ~]$vncpasswd

Password:

Verifty:

$ls -d .vnc

.vnc

$ls .vnc

passwd

$/sbin/service vncserver start

Starting VNC server:2:fangfang runuser:cannot set groups:Operation not permitted

[FAILED]

$sudo /sbin/service vncserver start

fangfang is not in the sudorers file.This incident will be reported.

退出仍用root用户

#sudo /sbin/service vncserver start

Starting VNC server:2:fangfang xauth:creating new authority file /home/fangfa

ng/.Xauthority

New 'fangfang.fw:2(fangfang)'desktop is fangfang.fw:2

Creating default startup script. /home/fangfang/.vnc/xstartup

Starting applications specified in /home/fangfang/.vnc/xstartup

Log file is /home/fangfang/.vnc/fangfang.fw:2.log

[OK]

这次成功了.

#cd .vnc (/home/fangfang/下)

#ls

fangfang.fw:2.log fangfag.fw:2.pid passwd xstartup

#vi xstartup

下面两行的注释去掉。

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

保存退出

重启vncserver

#sudo /sbin/service vncserver restart

Shutting down VNC server:2:fangfang [OK]

Starting VNC server:2:fangfang

New 'fangfang.fw:2(fangfang)'desktop is fangfang.fw:2

Starting application specified in /home/fangfang/.vnc/xstartup

Log file is /home/fangfang/.vnc/fangfang.fw:2.log

[OK]

在本机上试连接到vncserver

#vncviewer localhost:2

成功，打开了一个vnc窗口，输入口令，进入。

客户端的配置

如客户端为windows ,用putty详见SSH配置一文

客户端为linux：

1.vncviewer localhost:2 在本机执行

2.用ssh

ssh -L 5901:localhost:5901 -l foo myserver

需在sudo vi /etc/sysconfig/iptables中打开5901端口，

然后重启iptables

sudo /sbin/service iptables restart

或者直接用ip地址ssh -L 5901:localhost:5901 -l foo 192.168.x.x

Linux VNCserver的配置

1.查看VNC是否已经安装：

$ rpm -q vnc vnc-server

vnc是客户端,vnc-server是服务器端

2.把用户名加入到配置文件中：

CODE:[root@localhost ~]#  vi /etc/sysconfig/vncservers

# The VNCSERVERS variable is a list of display:user pairs.

#

# Uncomment the line below to start a VNC server on display :1

# 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:http://www.uk.research.att.com/vnc/sshvnc.html

# VNCSERVERS="1:myusername"

VNCSERVERS="1:root"

3.用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.

CODE:

[root@localhost ~]# vncpasswd

Password:

Verify:

[root@localhost ~]# ls -d .vnc

.vnc

[root@localhost ~]# ls .vnc

passwd

4.启动vnc服务.

CODE:[root@localhost ~]# service vncserver restart

Shutting down VNC server: 1:root                           [ OK ]

Starting VNC server: 1:root perl: warning: Setting locale failed.

perl: warning: Please check that your locale settings:

LANGUAGE = (unset),

LC_ALL = (unset),

LANG = "zh_EN.UTF-8"

are supported and installed on your system.

perl: warning: Falling back to the standard locale ("C").

New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1

Starting applications specified in /root/.vnc/xstartup

Log file is /root/.vnc/localhost.localdomain:1.log

[ OK ]

察看一下.vnc这个目录的内容，应该类似于下面的东西.

CODE:[root@localhost ~]# cd .vnc

[root@localhost .vnc]# ls

localhost.localdomain:1.log localhost.localdomain:2.log passwd

localhost.localdomain:1.pid localhost.localdomain:2.pid xstartup

[root@localhost .vnc]#

编辑这个名为xstartup的脚本，注意到下面红色的部分的注释

将这两行标记成红色的内容前面的注释符号去掉，否则你将只能得到一个什么都没有的灰屏。#!/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" &

twm &

因为我们已经修改了启动脚本，现在来重新启动vncserver.

CODE:[root@localhost .vnc]# service vncserver restart

Shutting down VNC server: 1:root                           [ OK ]

Starting VNC server: 1:root perl: warning: Setting locale failed.

perl: warning: Please check that your locale settings:

LANGUAGE = (unset),

LC_ALL = (unset),

LANG = "zh_EN.UTF-8"

are supported and installed on your system.

perl: warning: Falling back to the standard locale ("C").

New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1

Starting applications specified in /root/.vnc/xstartup

Log file is /root/.vnc/localhost.localdomain:1.log

[ OK ]

[root@localhost .vnc]#

5.防火墙端口设置

在使用防火墙的情况下来连接到一个远程系统,需要打开端口5901.

加入以下红色的部分，然后重启iptables服务。

[root@localhost ~]# vi /etc/sysconfig/iptables

# Firewall configuration written by redhat-config-securitylevel

# Manual customization of this file is not recommended.

*filter

:INPUT ACCEPT [0]

:FORWARD ACCEPT [0]

:OUTPUT ACCEPT [0]

:RH-Firewall-1-INPUT - [0]

-A INPUT -j RH-Firewall-1-INPUT

-A FORWARD -j RH-Firewall-1-INPUT

-A RH-Firewall-1-INPUT -i lo -j ACCEPT

-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT

-A RH-Firewall-1-INPUT -p 50 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

COMMIT

[root@localhost ~]# sudo /sbin/service iptables restart

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

其他：

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

1. 让vncserver接受两个不同的用户:

CODE:VNCSERVERS="1:root 2:yanyp"

当然你要为两个用户分别运行vncpasswd来设置口令. 并且在你的防火墙修改中，你应该明白VNC使用端口5901给连接1用，如果象上面一样要支持两个用户，应同时打开5901和5902.

2. 如果安装了用客户端vncviewer可以使用 vncviewer命令来远程连接vncserver

[root@localhost ~]$ vncviewer localhost(或者用IP地址):1

输入你的vnc口令，就可以了
