1, turn off the firewall and selinux

systemctl stop firewalld .service
setenforce 0

2, install the graphics support

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

 

3, install vncserver

yum -y install tigervnc-server

 

4, modify the configuration file

cp /lib/systemd/ system/[email protected] /etc/systemd/ system/vncserver@: 1.service

vim /etc/systemd/ system/vncserver@\: 1.service

To find two lines

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

I logged in as root, so as to modify

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

5, reload systemd

systemctl daemon-reload 

 

6, set vnc login password

vncpasswd 

 

7, start vncserver

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

8, to see whether it is normal to start

ps -ef | grep vnc

 

So far vncserver set up is completed.
