yum update -y
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm -y
yum install cobbler cobbler-web dhcp debmirror pykickstart fence-agents -y

systemctl start cobblerd httpd rsyncd tftp; systemctl enable cobblerd httpd rsyncd tftp

3.尝试访问一下cobbler的网址，登录的账号密码都是cobbler

https://IP/cobbler_web

4.设置安装系统的root密码

openssl passwd -1 -salt 'root' 'bzhantest'

5.设置cobbler配置文件

vim /etc/cobbler/settings

default_password_crypted: "$1$root$UXn3D/3xy8S5.CoOYeKHH/"
server: 192.168.49.3
next_server: 192.168.49.3
manage_dhcp: 1

6.配置debmirror.conf

sed -i 's/@dists="sid";/#@dists="sid";/g' /etc/debmirror.conf
sed -i 's/@arches="i386";/#@arches="i386";/g' /etc/debmirror.conf

7.配置tftp

vim /etc/xinetd.d/tftp
disable                 = no

8.下载引导文件

cobbler get-loaders

9.编辑dhcp文件

vim /etc/cobbler/dhcp.template
subnet 192.168.49.0 netmask 255.255.255.0 {
     option routers             192.168.49.2;
     option domain-name-servers 223.5.5.5;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.49.100 192.168.49.254;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

10.重启cobbler并同步

systemctl restart cobblerd
cobbler sync

11.检查cobbler check有没有错误

cobbler check

12.下载centos7镜像，挂在到/mnt/iso下，并导入到cobbler

mkdir /mnt/iso
mount CentOS-7-x86_64-Everything-1810.iso /mnt/iso
cobbler import --arch=x86_64 --path=/mnt/iso --name=CentOS7

13.回到cobbler网页，点击kickstart templates，创建ks模板。
