远程桌面连接centos 7

首先安装tigervnc-server:

yum install tigervnc-server

安装好后，设置 vi /etc/sysconfig/vncservers

[root@gateway-001 ~]# cat /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"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
VNCSERVERS="2:work"
VNCSERVERARGS[2]="-geometry 1024x768  -nolisten tcp -localhost"

启动vncserver服务器：

[root@gateway-001 ~]# service vncserver start

切换到work用户，设置vncpasswd

在服务器上可以看到打开的vnc端口：

在windows上安装viewvnc，输入ip地址和端口号进行连接：

输入密码：

可以看到成功的连接上了centos 6.5的桌面：
