安装环境： vnc服务端：
[root@localhost ~]# cat /etc/issue CentOS release 6.8 (Final) Kernel \r on an \mvnc客户端： win7-64
1、安装VNC
[root@localhost ~]# yum install tigervnc-server tigervnc -y2、配置vncservers文件
[root@localhost ~]# vim /etc/sysconfig/vncservers # 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: # https://access.redhat.com/knowledge/solutions/7027 # 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="1:root 2:lqs2" VNCSERVERARGS[1]="-geometry 1024x768 -nolisten tcp" VNCSERVERARGS[2]="-geometry 1024x768 -nolisten tcp" ~VNCSERVERS 是用来设定可以使用VNC的服务器账号，可以设定多个，例如上面root、lqs2，但是中间要用空格隔开。使用VNCVIEWER登录时，192.168.255.130:1表示是以root账号登录，以此类推。
关于参数配置说明：
1：-geometry 表示桌面分辨率，默认为1024x768，所以上面的1024x768也可以不写。
2：-nohttpd 表示不监听HTTP端口（58xx）。
3：-nolisten tcp 表示不监听TCP端口（60xx）
4：-localhost 只运行从本机访问。
5：AlwaysShared 默认只允许一个VNCVIEWER连接，此参数表示同一个显示端口允许多用户同时登录.
6：-depth 表示色深，参数有8,16,24,32.
7: SecurityTypes None 登录不需要密码认证VncAuth默认值,要密码认证。
3、设置VNC用户密码
如果此时不设置VNC用户密码，启动vncserver服务，则会报如下错误：
[root@localhost ~]# service vncserver start Starting VNC server: 1:root You will require a password to access your desktops. getpassword error: Inappropriate ioctl for device Password:2:lqs2 You will require a password to access your desktops. getpassword error: Inappropriate ioctl for device Password: [FAILED]设置密码
[root@localhost ~]# vncpasswd Password: Verify: [root@localhost ~]# su lqs2 [lqs2@localhost root]$ vncpasswd Password: Verify:4、启动vncserver服务
[lqs2@localhost root]$ su Password: [root@localhost ~]# vncserver [root@localhost .vnc]# ls localhost.localdomain:3.log localhost.localdomain:3.pid passwd xstartupVNC会在用户根目录($HOME)下的”.vnc”文件夹下生成一系列文件。其中passwd为vnc用户密码文件，由vncpasswd生成。其他的都由vnc初次启动时生成，xstartup为VNC客户端连接时启动的脚本
5、配置xstartup文件 只需修改最后一行
[root@localhost .vnc]# vim xstartup #!/bin/sh [ -r /etc/sysconfig/i18n ] && . /etc/sysconfig/i18n export LANG export SYSFONT vncconfig -iconic & unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS OS=`uname -s` if [ $OS = 'Linux' ]; then case "$WINDOWMANAGER" in *gnome*) if [ -e /etc/SuSE-release ]; then PATH=$PATH:/opt/gnome/bin export PATH fi ;; esac fi if [ -x /etc/X11/xinit/xinitrc ]; then exec /etc/X11/xinit/xinitrc fi if [ -f /etc/X11/xinit/xinitrc ]; then exec sh /etc/X11/xinit/xinitrc fi [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & gnome-session & 29,1 Bot切换到用户lqs2，并修改
[root@localhost .vnc]# su lqs2 [lqs2@localhost .vnc]$ [lqs2@localhost .vnc]$ vim /home/lqs2/.vnc/xstartup export SYSFONT vncconfig -iconic & unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS OS=`uname -s` if [ $OS = 'Linux' ]; then case "$WINDOWMANAGER" in *gnome*) if [ -e /etc/SuSE-release ]; then PATH=$PATH:/opt/gnome/bin export PATH fi ;; esac fi if [ -x /etc/X11/xinit/xinitrc ]; then exec /etc/X11/xinit/xinitrc fi if [ -f /etc/X11/xinit/xinitrc ]; then exec sh /etc/X11/xinit/xinitrc fi [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & gnome-session &启动vnc-server
[root@localhost .vnc]# service vncserver restart Shutting down VNC server: 1:root 2:lqs2 [ OK ] Starting VNC server: 1:root Warning: localhost.localdomain:1 is taken because of /tmp/.X1-lock Remove this file if there is no X server localhost.localdomain:1 A VNC server is already running as :1 2:lqs2 New 'localhost.localdomain:2 (lqs2)' desktop is localhost.localdomain:2 Starting applications specified in /home/lqs2/.vnc/xstartup Log file is /home/lqs2/.vnc/localhost.localdomain:2.log [ OK ]6、配置防火墙
[root@localhost ~]# iptables -I INPUT -p tcp --dport 5901 -j ACCEPT [root@localhost ~]# iptables -I INPUT -p tcp --dport 5902 -j ACCEPT关于VNC服务使用的端口号与桌面号相关，VNC使用TCP端口从5900开始，对应关系如下 桌面号为“1” —- 端口号为5901 桌面号为“2” —- 端口号为5902 桌面号为“3” —- 端口号为5903 …… 基于Java的VNC客户程序Web服务TCP端口从5800开始，也是与桌面号相关，对应关系如下 桌面号为“1” —- 端口号为5801 桌面号为“2” —- 端口号为5802 桌面号为“3” —- 端口号为5803
开机自启动vncserver
[root@localhost ~]# chkconfig vncserver onwin7下载vnc viewer，连接访问 [参考资料]： http://www.cnblogs.com/kerrycode/p/3315793.html http://www.ha97.com/4634.html
