一、虛擬機 硬體配置
CPU 4 cores + Ram 16GB + OS硬碟32GB + DATA硬碟 200GB


設定IP : 192.168.120.201/24

硬碟空間切割及掛載

yum install xCAT


取讀設定檔 source /etc/profile.d/xcat.sh

取得設定資訊 xcatprobe xcatmn

chtab key=system passwd.username=root passwd.password=Nchc@1234

tabdump site (列出站台資訊)

lsxcatd -a (檢查xCAT版本)

chdef -t site dhcpinterfaces=ens192 (定義DHCP介面)

makedns -n (讓DNS Service正常)

makedhcp -a
makedhcp -n (讓DHCP Service正常)

yum install ntp
makentp -a


copycds -n centos7.8 CentOS-7_8-x86_64-DVD-2003.iso (將系統ISO檔讀入系統，並命名為 centos7.8)
