One click DD Linux System Usage

Basically, all VPS server vendors will provide free Linux systems for installation, such as CentOS, Debian, Ubuntu, etc. Then why use the one button DD script to reinstall/replace the system?

The system version provided by the merchant is limited and may not have the version you need.
Merchants' systems have services they don't want, such as Alibaba Cloud Shield (Anqie) in China.
The vendor's system cannot install specific software, such as the sharp core.
In the above cases, the one click DD script can replace a pure system for the server and help you solve the problem.

Environment required

Take Vicer's one button DD, which is widely spread on the Internet, for example. The required environment is:

Architecture: KVM/XEN, does not support OpenVZ.

About the system reinstallation process

There are three possible scenarios:

Under normal circumstances, the installation is successful in about 10 minutes. During this period, you can observe the installation process in VNC:
