1、关闭防火墙和selinux

systemctl stop firewalld.service
setenforce 0

2、安装图形支持

yum groups install "GNOME Desktop"或yum groups install "X Window System"

3、安装vncserver

yum -y install tigervnc-server

4、修改配置文件

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.servicevim /etc/systemd/system/vncserver@\:1.service 

找到这两行

ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
PIDFile=/home/<USER>/.vnc/%H%i.pid

我以root登陆，所以修改为

ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i"
PIDFile=/root/.vnc/%H%i.pid

5、重新加载systemd

systemctl daemon-reload 

6、设置vnc登陆密码

vncpasswd 

7、启动vncserver

systemctl enable vncserver@:1.service
systemctl start vncserver@:1.service 

8、查看是否正常启动

ps -ef | grep vnc

至此vncserver搭建完毕。
