linux 远程桌面的配置

root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developer用户名加入vncservers文件中
如下所示：
# VNCSERVERS="2:myusername"
VNCSERVERS="2:developer"
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:developer      [FAILED]
后来改为用户developer,并在/home/developer目录下创建vnc的口令
[developer@developer ~]$vncpasswd
Password:
Verifty:
$ls -d .vnc
.vnc
$ls .vnc
passwd
$/sbin/service vncserver start
Starting VNC server:2:developer runuser:cannot set groups:Operation not permitted  [FAILED]
$sudo /sbin/service vncserver start
developer 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:developer xauth:creating new authority file /home/developer/.Authority
New 'developer.fw:2(developer)'desktop is developer.fw:2
Creating default startup script. /home/developer/.vnc/xstartup
Starting applications specified in /home/developer/.vnc/xstartup
Log file is /home/developer/.vnc/developer.fw:2.log   [OK]
这次成功了.
#cd .vnc 
(/home/developer/下）
#ls
developer.fw:2.log 
developer.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:developer   [OK]
Starting VNC server:2:developer
New 'developer.fw:2(developer)'desktop is developer.fw:2
Starting application specified in /home/developer/.vnc/xstartup
Log file is /home/developer/.vnc/developer.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或vnc客户端
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
