CentOS 6安装和配置VNC

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 -p 51 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -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

Flushing firewall rules: [ OK ]

Setting chains to policy ACCEPT: filter [ OK ]

Unloading iptables modules: [ OK ]

Applying iptables firewall rules: [ OK ]

[root@localhost ~]#

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
