1.2.6 compile the ks. cfg file

In general, we need a lot of interactive operations with the server during the installation of the operating system. In order to reduce this interaction process, kickstart was born. To use kickstart, you only need to define a Kickstart automatic response configuration file ks in advance. cfg (usually stored on the Installation server), and let the installation program know the location of the configuration file. During the installation process, the installation program can read the installation configuration from the file by itself, in this way, human-computer interaction is avoided multiple times during the installation process, so as to achieve unattended automatic installation.

1.3 installation demonstration

1.3.1. VMware creates a blank Virtual Machine (automatic detection and CentOS7 memory at least 2 GB)

1.3.2 click Start Virtual Machine. Now you can have tea and wait.
