修改配置檔案    vim ks.cfg

用 ksvalidator ks.cfg指令檢視有沒有文法錯誤

寫腳本！！！  --extra-args "ks=http://172.25.12.250/ks.cfg"

測試－－〉在浏覽器輸入  172.25.12.250/ks.cfg

二、dhcp

1.安裝

yum install dhcp -y

systemctl start dhcpd

2.生成配置檔案 

 cp /usr/share/doc/dhcp*/dhcpd.conf.example  /etc/dhcp/dhcpd.conf

3.修改配置檔案完成配置

vim /etc/dhcp/dhcpd.conf

  1 # dhcpd.conf

  2 #

  3 # Sample configuration file for ISC dhcpd

  4 #

  5 

  6 # option definitions common to all supported networks...

  7 option domain-name "westos.com";   ##指定域名

  8 option domain-name-servers 192.168.43.1; ##指定客戶主機獲得到的dns

  9 

 10 default-lease-time 600;   ##最短租約期

 11 max-lease-time 7200;   ##最長租約期

 27 #subnet 10.152.187.0 netmask 255.255.255.0 {      #

 28 #}

 29 

 30 # This is a very basic subnet declaration.

 31 

 32 subnet 172.25.254.0 netmask 255.255.255.0 {

 33   range 172.25.254.109 172.25.254.200;

 34   option routers 172.25.254.9;

 35 }

 36  行以後的全部删除

4.重新開機服務

systemctl restart dhcpd

5.測試

拔掉網線測試
