centos7在kickstart下的安装

 

 

 

核心就是三个服务:

DHCP TFTP  HTTP

第一步安装DHCP服务

yum -y install dhcp

 

 

修改DHCP文件

cat >>/etc/dhcp/dhcpd.conf<<EOF

subnet 172.16.1.0 netmask 255.255.255.0 {

range 172.16.1.100 172.16.1.199;

option subnet-mask 255.255.255.0;

default-lease-time 21600;

max-lease-time 43200;

next-server 172.16.1.201;

filename "/pxelinux.0";

}

 

EOF

启动服务

systemctl start dhcpd

 ============================================================================================================================================

第二步安装TFTP服务

yum -y install tftp-server
systemctl start tftp.socket

yum -y install syslinux
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

创建目录,挂载磁盘到服务器

mkdir -p /var/www/html/CentOS7
mount /dev/cdrom /var/www/html/CentOS7 

第三.制作默认文件

cp -a /var/www/html/CentOS7/isolinux/* /var/lib/tftpboot/
mkdir -p /var/lib/tftpboot/pxelinux.cfg
cp /var/www/html/CentOS7/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

[root@kickstart ~]# cat /var/lib/tftpboot/pxelinux.cfg/default 
default ks
prompt 0

label ks
  kernel vmlinuz
  append initrd=initrd.img ks=http://172.16.1.201/ks_config/CentOS7-ks.cfg net.ifnames=0 biosdevname=0 ksdevice=eth1

 

第四安装HTTP

 

[root@kickstart tftpboot]# cat /var/www/html/ks_config/CentOS7-ks.cfg
