centOS5.5-64内置xvnc连接失败问题解决: 改端口5902

一。启动vnc服务：跟32位CentOs不同，需要手工改动（如下），并使用5902端口连接，成功：

Step 1

You need to modify /etc/sysconfig/vncservers

Here you would put the desktop number and name. The name is a user on

the system.

VNCSERVERS="2:someuser"

不要uncomment下边那行：vncserverARGS

Step 2 run chkconfig and make sure vncserver is enabled and on the

levels you wanted it to run on.

Step 3

As root

su - someuser

Run vncpasswd and generate a vnc password

Step 4

Start vnc

service vncserver start

过程：上述4步后、vnc启动成功；但还是连不上，提示failed to connect..开始以为看 /var/log/messages可以搞定，但完全没用，其他log目录下的内容也看了，一样没用；再后来:ps -ef|grep vncserver,得到了一行信息，其中有 port=5902字样，马上在viewer上ip地址后增加5902，搞定！、

二。开始vnc连到的桌面极其简陋，需要调整xmanager：

You might prefer the VNC desktop session to look and behave the same as the login session you would normally see. To do that, edit the file

/home/username/.vnc/xstartup

and remove the

#

from the beginning of the two lines that follow the line reading "

Uncomment the following two lines for normal desktop

."

这里的/home/username，可用~ 代替。
