linux 下vnc服务的配置
1、软件安装
[root@jedy ~]# yum install -y tigervnc-server
2、修改配置文件
[root@tian ~]# cat /etc/sysconfig/vncservers \\更改配置文件 # 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 this URL: # http://kbase.redhat.com/faq/docs/DOC-7028 # Use "-nolisten tcp" to prevent X connections to your VNC server via TCP. # 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="2:myusername" # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost" VNCSERVERS="1:root 10:aa 20:bb 30:tt" \\增加root和tt用户的vnc配置 ，注意 下面两行要去掉 "-localhost",要不然就只会在 127.0.0.1 端口开启vnc服务了。 VNCSERVERARGS[1]="-geometry 800x600 -nolisten tcp" VNCSERVERARGS[10]="-geometry 800x600 -nolisten tcp" VNCSERVERARGS[20]="-geometry 800x600 -nolisten tcp" VNCSERVERARGS[30]="-geometry 800x600 -nolisten tcp [root@tian ~]#
3、启动报务
[root@tian ~]# service vncserver restart Shutting down VNC server: 1:root 10:aa 20:bb 30:tt [FAILED] Starting VNC server: 1:root 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 10:aa New 'localhost.localdomain:10 (aa)' desktop is localhost.localdomain:10 Starting applications specified in /home/aa/.vnc/xstartup Log file is /home/aa/.vnc/localhost.localdomain:10.log 20:bb VNC password for user bb is not configured [FAILED] \\ 这里报错是因为 没有设置vnc密码。必须手工设置vnc密码 [root@tian ~]# [root@tian ~]# su bb [bb@localhost root]$ vncserver :20 You will require a password to access your desktops.

使用客户端连接时只要加上桌面号就行了10，
[root@tian ~]# vncviewer 127.0.0.1:10
补充内容
1、更改默认端口号
[root@tian ~]# which vncserver
/usr/bin/vncserver
[root@tian ~]#
[root@tian ~]# more `which vncserver` | grep 5900
$vncPort = 5900 + $displayNumber;
# n is taken if something is listening on the VNC server port (5900+n) or the
# (5900+n) or the X server port (6000+n).
if (!bind(S, pack('S n x12', $AF_INET, 5900 + $n))) {
[root@tian ~]#
[root@tian ~]# sed -i.bak 's/5900/6900/g' /usr/bin/vncserver
[root@tian ~]# more `which vncserver` | grep 6900
$vncPort = 6900 + $displayNumber;
# n is taken if something is listening on the VNC server port (6900+n) or the
# (6900+n) or the X server port (6000+n).
if (!bind(S, pack('S n x12', $AF_INET, 6900 + $n))) {
[root@tian ~]#
[root@tian ~]# service vncserver restart

[root@tian ~]#
注意：更改了端口号后，使用客户端连接时要加上完整的端口号 如
[root@tian ~]# vncviewer 127.0.0.1:6910
配置完成
