Kickstart 制作

1 .编辑镜像 引导文件

isolinux.cfg

第一行：  default linux ks=cdrom:/ks.cfg

2. 编辑软件包配置文件 ks.cfg

# 使用文本安装界面
install


#使用光驱作为安装媒介
cdrom
lang en_US.UTF-8
keyboard us
network --device eth0 --onboot yes --bootproto dhcp

#root passwd 需要编辑 $后面的东西
rootpw --iscrypted $这儿需要重新设置
# System authorization information
auth  --useshadow  --passalgo=sha512

#安装模式
text
#关闭防火墙
firewall --disable
selinux --disable

#firewall --enabled --port=23:tcp
#authconfig --enableshadow --enablemd5
#selinux --enforcing
#安装完成自动重启,并弹出cdrom
reboot --eject
#  设置时区
timezone --utc Asia/Shanghai
bootloader --location=mbr --driveorder=sda
#clear the master boot Record
zerombr

clearpart --all
# install linux
# 分区设置
part /boot --fstype ext3 --size=100
part swap --size=8000
part / --fstype ext4 --size=20000 
part /usr --fstype ext4 --size=20000
