1、修改YUM仓库

vim /etc/yum.repos.d/my.repo

[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/
enabled=1
gpgcheck=0

2、安装cobbler

yum install dhcp httpd xinetd tftp cobbler cobbler-web -y

3、修改cobbler配置文件

生成加密密码：openssl passwd -1 -salt bw.com 123456

vim /etc/cobbler/settings

server: 192.168.100.100
next_server: 192.168.100.100
default_password_crypted: "$1$stu.com$Pp0HQwZhSF...mXIxjJAH." #root管理员密码

4、配置DHCP

vim /etc/dhcpd/dhcp.conf

option domain-name "stu.com";
option domain-name-servers 192.168.100.100;
default-lease-time 36000;
max-lease-time 72000;
log-facility local7;

subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.110 192.168.100.150;
option routers 192.168.100.1;
option broadcast-address 192.168.100.255;
next-server 192.168.100.100;
filename "pxelinux.0";
}

systemctl start dhcpd
systemctl enable dhcpd

5、配置tftp

vim /etc/xinetd.d/tftp

disable= no

systemctl start xinetd
systemctl enable xinetd

6、下载启动引导文件

cobbler get-loaders

7、导入光盘镜像文件

cobbler import --path=/mnt/cdrom --name=c75 --arch=x86_64

8、生成自动应答文件

vim /var/lib/cobbler/kickstarts/c75.ks

#platform=x86, AMD64, Intel EM64T
#version=DEVEL

Install OS instead of upgrade

install

Keyboard layouts

keyboard ‘us‘

Root password

rootpw --iscrypted $default_password_crypted #见第3步

System timezone

timezone Asia/Shanghai

Use network installation

url --url=$tree

System language

lang en_US.UTF-8

Firewall configuration

firewall --disabled

System authorization information

auth --useshadow --enablemd5

Use graphical install

text
firstboot --disable

SELinux configuration

selinux --disabled

Reboot after installation

reboot

System bootloader configuration

bootloader --location=mbr

Clear the Master Boot Record

zerombr

Partition clearing information

clearpart --all --initlabel

Disk partitioning information

part /boot --fstype="xfs" --size=256
part swap --fstype="swap" --size=1024
part / --fstype="xfs" --ondisk=sda --size=1 --grow #使用全部剩余空间

Network information

$SNIPPET(‘network_config‘)

%pre
$SNIPPET(‘log_ks_pre‘)
$SNIPPET(‘kickstart_start‘)
$SNIPPET(‘pre_install_network_config‘)

Enable installation monitoring

$SNIPPET(‘pre_anamon‘)
