Don't say much nonsense, the following records the installation process:
1) Install the desktop environment

[Email protected] ~]# yum-y groupinstall "X Window System" [[email protected] ~]# yum-y groupinstall "Desktop" [email p Rotected] ~]# yum-y Groupinstall "General Purpose Desktop" [[email protected] ~]# startx                //or use "Init 5" command to start the graphical interface; turn off graphics The interface needs to execute the "Init 3" command after executing the     above STARTX command (can be executed in the background, or CTRL+Z;BG 1;disown-a), the server's desktop mode is started. When you connect using VNC, you will find that you are already in desktop mode.

2) Modify the CentOS system to start in desktop mode

[Email protected] ~]# cat/etc/inittab ... #id: 3:initdefault:               //Start the system in text mode Id:5:initdefault:                //Start the system in desktop mode

3) VNC Remote Desktop Connection environment installation

In CentOS, Xstartup's file path is:/root/.vnc/(You can view Xstartup's file path through Locatexstartup) so you need to execute: chmod 777/root/.vnc/xstartup to give permissions. Then restart the vncserver. Finally, in the local Windows installation VNC viewer, remote access installs the VNC client under Windows: https://pan.baidu.com/s/ 1hrsir4k Extract Password: DQDTVNC Remote connection information (IP below is the address of the VNC server): VNC server:172.16.220.139:5901encrytion:let VNC servers Choose then enter the VNCPASSWD password to complete the VNC remote connection!
