怎样在CentOS 7.0上安装和配置VNC服务器

CentOS系统中VNC配置，检查VNC客户端和服务器端、将用户名加入到配置文件、启动VNC服务、修改VNC SERVER的窗口治理器等必要问题。
1检查VNC客户端和服务器端是否已经安装
执行如下命令：
[root@localhost ~]# rpm -qa vnc vnc-server
package vnc is not installed
package vnc-server is not installed
表示系统没有安装VNC服务端，那我们就用yum安装VNC服务端。
[root@localhost ~]# yum -y install vnc vnc-server

Complete!
启动VNC Server服务:使用vncserver命令(在当前用户主目录下生成vnc文件夹)
[root@localhost ~]# vncserver
You will require a password to access your desktops
Password:
Verify:
xauth: creating new authority file /root/Xauthority
New 'localhostlocaldomain:1 (root)' desktop is localhostlocaldomain:1
Creating default startup script /root/vnc/xstartup
Starting applications specified in /root/vnc/xstartup
Log file is /root/vnc/localhostlocaldomain:1log
2 在CentOS系统中将用户名加入到配置文件中
编辑vncservers的配置文件
[root@localhost ~]# vi /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:
