第一步:安装VNC
  1. 安装vnc
  yum install -y tigervnc*
  2.启动vncserver
  [root@xxx ~]# vncserver
  You will require a password to access your desktops.
  Password:<输入密码>
  Verify:<输入密码>
  xauth: creating new authority file /root/.Xauthority
  New 'xxx:1 (root)' desktop is xxx:1
  Creating default startup script /root/.vnc/xstartup
  Starting applications specified in /root/.vnc/xstartup
  Log file is /root/.vnc/xxx:1.log
  3.配置VNC Server启动文件
  网上看了很多有关文章,说需要改 ~HOME/.vnc/xstartup 文件的,但是我没有修改,当然图形界面还是要安装的
  yum -y install gnome*
  配置/etc/sysconfig/vncserver文件
  VNCSERVERS="10:root"
  VNCSERVERARGS[10]="-geometry 1024x768 -nolistien tcp"
  端口号、用户、分辨率根据实际情况修改,保存退出
  vncserver -list        #查看是否有多个端口
  vncserver -kill :x     #删除不用的端口
  vncserver :10          #启动vncserver
  注:重启vncserver后,在windows系统安装vncviewer,输入IP:端口号和密码可以进入图形界面了
  如果界面出现乱码,可能是由于linux系统是中文安装的,修改 /etc/sysconfig/i18n 文件转换中英文
  第二步:安装VirtualBox
  1.安装DKMS内核,进入dkms官网下载rpm包后安装,下载地址:http://linux.dell.com/dkms
  wget http://linux.dell.com/dkms/permalink/dkms-2.2.0.3-1.noarch.rpm
  rpm -ivh dkms-2.2.0.3-1.noarch.rpm
  2.下载VirtualBox的RPM安装包,下载地址:https://www.virtualbox.org/wiki/Downloads
  wget http://download.virtualbox.org/virtualbox/4.3.28/VirtualBox-4.3-4.3.28_100309_el6-1.x86_64.rpm
  rpm -ivh VirtualBox-4.3-4.3.6_91406_el6-1.x86_64.rpm
  在安装完之后,出现下面错误信息:
  No precompiled module for this kernel found -- trying to build one. Messages
  emitted during module compilation will be logged to /var/log/vbox-install.log.
  Stopping VirtualBox kernel modules [ OK ]
  Uninstalling old VirtualBox DKMS kernel modules [ OK ]
  Trying to register the VirtualBox kernel modules using DKMSError! echo
  Your kernel headers for kernel 2.6.32-358.el6.x86_64 cannot be found at
  /lib/modules/2.6.32-358.el6.x86_64/build or /lib/modules/2.6.32-358.el6.x86_64/source.
  [FAILED]
  (Failed, trying without DKMS)
  Recompiling VirtualBox kernel modules [FAILED]
  (Look at /var/log/vbox-install.log to find out what went wrong)
  解决方法:
  安装kernel-devel软件包
  yum install kernel-devel-$(uname -r)
  如果yum没有安装源,可以到http://rpmfind.net/linux/rpm2html搜索相应系统的版本下载安装
  第三步:启动VirtualBox相关服务
  service vboxdrv setup
  当出现下面运行信息时说明启动成功,这时可以创建虚拟机了。

  Uninstalling old VirtualBox DKMS kernel modules [确定]
