Restart the CentOS server: # reboot

Open the Xbrowser of Xmanager in Windows, enter the CentOS server IP in the address bar and enter to connect.

# yum-y install system-config-kickstart

# system-config-kickstart & / / & indicates running in the background

File-- > Open File-- > find anaconda-ks.cfg-- > Open-- > after importing anaconda-ks.cfg, edit as needed-- > File-- > Save as ks.cfg
