一、配置kickstart應答檔案
要想配置kickstart ，首先要配置個本地yum源，要不然用system-config-kickstart時選不上包。而且，centos6的yum 源的名字一定是[base],要不然會報:
package selection is disabled due to problems downloading package information.
centos7要把倉庫名稱更改為development
[development]
name=base
baseurl=file:///mnt/
利用安裝system-config-kickstart
yum -y system-config-kickstart
如果不能啟動，用xshell,連接配接，左鍵屬性，隧道勾選轉發x11連接配接到(x)，選擇xmanager(m)
安裝httpd服務，執行system-config-kickstart時會用到httpd服務來對安裝檔案目錄進行配置
yum -y install httpd
mkdir /var/www/html/7/x86_64 -p
mount /dev/sr0 /var/www/html/7/x86_64
systemctl start httpd
二、設定dhcp伺服器
rpm -ivh /var/www/html/6/packages/dhcp-4.1.1-60.p1.el6.centos.x86_64.rpm
vim /etc/dhcp/dhcpd.conf
option domain-name "magedu.com"; ping自動補全
option domain-name-servers 192.168.0.1,8.8.8.8; dns1dns2
default-lease-time 86400; 預設租期
max-lease-time 86400; 用戶端可擷取的最長租期
subnet 192.168.100.0 netmask 255.255.255.0 { 網段及掩碼
range 192.168.100.1 192.168.100.200; 配置設定的ip位址
option routers 192.168.100.1; 配置設定的網關位址
}
service dhcpd start
vim /var/lib/dhcpd/dhcpd.leases 檢視配置設定記錄
三、設定tftp伺服器
yum -y install tftp-server
vim /etc/xinetd.d/tftp
disable = no
service xinetd start
ss -unlp | grep xinetd 檢視是否監聽udp的69端口
tftp共享檔案目錄在/var/lib/tftpboot
四、準備pxe安裝centos系統
mkdir /var/lib/tftpboot/pxelinux.cfg/
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cd /misc/cd/images/pxeboot/
cp vmlinuz initrd.img /var/lib/tftpboot
cd /misc/cd/isolinux/
cp boot.msg vesamenu.c32 splash.jpg /var/lib/tftpboot
vim /var/lib/tftpboot/pxelinux.cfg/default
default vesamenu.c32 指定菜單風格
#prompt 1
timeout 600
display boot.msg
menu background splash.jpg
menu title welcome to wang centos 6
menu color border 0 #ffffffff #00000000
menu color sel 7 #ffffffff #ff000000

menu label ^manual install centos
append initrd=initrd.img inst.repo=http://192.168.100.100/centos/6
label local
menu default
menu label boot from ^local drive
localboot 0xffff
