Centos7 installation graphical interface:

Step 1: install the Gnome package

Enter the following command at the command line to install the Gnome package.

# yum groupinstall "GNOME Desktop"Graphical Administration Tools"

Step 2: update the run level of the system.

# ln-sf / lib/systemd/system/runlevel5.target / etc/systemd/system/default.target

Step 3: restart the machine. Start to enter the graphical interface by default.

# reboot

/ / Note: when rebooting to enter the interface, you may encounter the following situations:

Initial setup of CentOS Linux 7 (core)

1) [x] Creat user 2) [!] License information

(no user will be created) (license not accepted)

Please make your choice from above ['q' to quit |'c' to continue |'r' to refresh]:

Solution:

Enter "1" and press Enter

Enter "2" and press Enter

Enter "Q" and press Enter

Enter "yes" and press Enter

First of all, try to see if the server has VNC installed.

[root@wic] # rpm-Q tigervnc tigervnc-server

If it is not installed, it will appear directly.

Package tigervnc is not installedpackage tigervnc-server is not installed

If you do not have a desktop installed, install GNOME Desktop first

[root@wic ~] # yum groupinstall GNOME Desktop

Step 1: install VNC packages:

[root@wic ~] # yum install tigervnc-server-y

The second step is to modify the configuration information, create a folder under / etc/systemd/system/ and copy the example config file from / lib/systemd/system/vncserver@.service to vncserver@:1.service

[root@wic ~] # cp / lib/systemd/system/vncserver@.service / etc/systemd/system/vncserver@:1.service

Then open the configuration file / etc/systemd/system/vncserver@:1.service to replace the default user name

Find this business.

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

Here I log in directly as the root user, so I replace it with

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

Step 3, reload systemd

[root@wic ~] # systemctl daemon-reload

Step 4, set the password for VNC

[root@wic ~] # vncpasswd

Step 5, because Centos 7 on my side uses iptable firewall, so

Vim / etc/sysconfig/iptables

Add in the appropriate position

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 5900 tcp 5903-j ACCEPT

Restart iptable

Service iptables restart

If you are using Centos 7 default firewall, you may need to

[root@wic] # firewall-cmd-- permanent-- add-service vnc-server [root@wic ~] # systemctl restart firewalld.service

Step 6: start and enable VNC by default

[root@wic ~] # systemctl enable vncserver@:1.service [root@wic ~] # systemctl start vncserver@:1.service

So basically the Centos side is set up, and the Windows side is going to the next VNC Viewer software. Connect to VNCSERVER_IP:1 and try it. It looks a little shabby, but it goes up.
