Install the Remote Desktop Server software VNC Server and centos6.5vnc under CentOS6.5

VNC allows you to remotely access and control your computer from another computer or mobile device, wherever you are in the world. Common Use Cases include providing desktop support to colleagues and friends, and Remotely Managing Your servers.

Deploy the VNC Server to the computer you want to control, and use the VNC Viewer to connect to the computer you want to control.

Installation Service:

Yum install tigervnc-server

This name is a bit strange. If you never know it, you cannot guess it.

How to download the installation file of the VNC Server from the official website? How to Use the VNC Viewer to connect to a remote CentOS Server?

What is the difference between setting Remote Desktop preferences in CentOS and enabling VNC Server?

It is actually the same method,
The default port 0 is used to enable the Remote Desktop preference.
You can enter the IP Address: 0 to test.

In windows, how does one remotely connect to the linux system desktop through vnc?

1. Installation graphical interface:
1) install the logon MANAGER: $ sudo apt-get install TPD
2) install the desktop environment and install only the most basic components: $ sudo apt-get install gnome-core (after installation, you can use the startx command to start the GUI)
3) install the graphic interface (automatically install the application): $ sudo apt-get install ubuntu-desktop (restart the system after installation)

2. Install vnc server (VNC server) in ubuntu ):
$ Sudo apt-get install vnc4server

3 Start the VNC service: $ vncserver: 1 (Number 1 indicates the desktop number)
Run the following command to connect to the ubuntu server at the same time: $ vncserver-geometry 1280 × 800-alwaysshared: 1 (-geometry 1280 × 800 indicates the resolution, -alwaysshared indicates that multiple users can connect to the same desktop at the same time)

Stop the VNC service: $ vncserver-kill: 1

4. In the ubuntuc server graphical interface, set the allowed end-range Logon:
System> Preferences> Remote Desktop:

After setting the password, you can remotely connect to ubuntu server through vnc viewer on the windows client!
