CentOS安装使用vnc进行远程桌面登录
以下介绍在CentOS 7下安装vncserver并使用vnc-viewer进行登录(使用root权限)：
1、运行命令yum install tigervnc-server安装vncserver；
2、运行命令yum install vnc安装vnc；//感觉不安装也可以，安装一下也很快，不要在意这些细节
3、运行命令yum groupinstall "X Window System"安装X-Window；//之前安装发现经常无法启动vncserver，后面通过网上查资料介绍可以安装X-Window解决这个 问题
4、安装中文字符以解决界面中文乱码的问题：yum install dejavu-lgc-sans-fonts、yum groupinstall "Fonts" -y
5、禁用防火墙，如果已经禁用防火墙可以跳过这一步：systemctl stop firewalld.service、systemctl disable firewalld.service
6、配置vncserver：
拷贝创建一个新的配置文件，以开启1号窗口为例，如果需要开启多个则创建多个配置文件即可：
[root@localhost ~]# cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:1.service
修改配置文件内容
[root@localhost ~]# vi /lib/systemd/system/vncserver@:1.service
The vncserver service unit file
Quick HowTo:
1. Copy this file to /etc/systemd/system/vncserver@.service
2. Replace with the actual user name and edit vncserver
parameters appropriately
("User=" and "/home//.vnc/%H%i.pid")
3. Run systemctl daemon-reload
4. Run systemctl enable vncserver@:<display>.service
DO NOT RUN THIS SERVICE if your local area network is
untrusted! For a secure way of using VNC, you should
limit connections to the local host and then tunnel from
the machine you want to view VNC on (host A) to the machine
whose VNC output you want to view (host B)
[user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB
this will open a connection on port 590N of your hostA to hostB's port 590M
(in fact, it ssh-connects to hostB and then connects to localhost (on hostB).
See the ssh man page for details on port forwarding)
You can then point a VNC client on hostA at vncdisplay N of localhost and with
the help of ssh, you end up seeing what hostB makes available on port 590M
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.

7、运行命令systemctl daemon-reload更新systemctl；
8、运行命令vncpasswd root设置vncserver的密码；
9、运行命令systemctl start vncserver@:1.service(可以运行systemctl enable vncserver@:1.service命令设置为默认启动服务)；//启动不了则重启一下系统或则查看启动日志
10、重启系统后使用VNC-Viewer连接：192.168.10.100:1,输入设置的密码即可登录。
