linux - 虚拟机的自动安装与dhcp

  一、实现虚拟机的“全自动安装”

步骤  ---->  yum install systemctl-config-kickstart  -y

修改配置文件    vim ks.cfg

用 ksvalidator ks.cfg命令查看有没有语法错误

写脚本！！！  --extra-args "ks=http://172.25.12.250/ks.cfg"

测试－－〉在浏览器输入  172.25.12.250/ks.cfg

二、dhcp

1.安装

yum install dhcp -y

systemctl start dhcpd

2.生成配置文件 

    

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

3.修改配置文件完成配置

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; ##指定客户主机获得到的dns
  9 
 10 default-lease-time 600;   ##最短租约期
 11 max-lease-time 7200;   ##最长租约期

 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  行以后的全部删除

4.重启服务

systemctl restart dhcpd

5.测试

拔掉网线测试
