# cobbler是基于pxe(dhcpclient,tdtp-client)网卡-现代网卡都是pxe的 跟着cobbler check即可

根绝cobbbler check提示，做完一个之后，先重启紧接着就cobbler sync # 准备

防火墙和selinux关闭
dhcp服务器设置为静态ip
虚拟机:勾选不分配ip并基于nat模式

1.安装相关包并启动服务

# 安装cobbler自动把依赖包httpd,tftp,syslinux-nonlinux装好
[root@centos7 ~]#yum install cobbler dhcp
[root@centos7 ~]#systemctl enable --now cobblerd httpd tftp dhcpd
# dhcp起不起来，因为没有配置

2.修改cobbler配置文件

[root@centos7 ~]#vim /etc/cobbler/settings 

default_password_crypted: "$1$gEc7ilpP$pg5iSOj/mlxTxEslhRvyp/"
# 这个密码通过open-ssl passwd -1 可以生成md5加密的
next_server：< tftp服务器的 IP 地址>
server：<cobbler服务器的 IP 地址>
manage_dhcp：1  #设置为1，表示通过cobbler生成dhcpd.conf配置文件
pxe_just_once: 1 避免客户机pxe处于第一位导致循环重启

[root@centos7 ~]#systemctl restart cobblerd
[root@centos7 ~]#cobbler sync

3.准备启动相关文件

[root@centos7 ~]#cobbler get-loaders
[root@centos7 ~]#ls /var/lib/cobbler/loaders
[root@centos7 ~]#cobbler sync 
# cobbler sync相当于同步功能
[root@centos7 ~]#tree /var/lib/tftpboot/

4.配置dhcp服务

#修改dhcp的模版文件下面的行，用来生成dhcp的配置文件
[root@centos7 ~]#vim /etc/cobbler/dhcp.template
subnet 192.168.100.0 netmask 255.255.255.0 {
     option routers             192.168.100.1;
     option domain-name-servers 180.76.76.76,223.6.6.6;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp       192.168.100.1 192.168.100.200;
[root@centos7 ~]#cobbler sync
[root@centos7 ~]#systemctl start dhcpd

# 上面的做完了，前期准备就可以了，剩下的就是根据菜单准备对应资源了，应答文件以及内核和虚拟文件系统

5.修改菜单标题信息

[root@centos7 ~]#vim /etc/cobbler/pxe/pxedefault.template
MENU TITLE Cobbler | qq 3555409634
[root@centos7 ~]#cobbler sync
[root@centos7 ~]#cat /var/lib/tftpboot/pxelinux.cfg/default

6.导入centos系统镜像，生成对应的虚拟文件系统和内核，以及作为网络源

[root@centos7 ~]#mount /dev/sr1 /mnt
# 注意arch前面有两个--
[root@centos7 ~]#cobbler import --name=centos-8.1-x86_64 --path=/misc/cd --arch=x86_64
[root@centos7 ~]#du -sh /var/www/cobbler/ks_mirror/*
[root@centos7 ~]#cobbler distro list
[root@centos7 ~]#cobbler profile list
默认的是生成最小化安装的应答文件

7.准备kickstart应答文件，并关联

[root@centos7 ~]#vim /var/lib/cobbler/kickstarts/ks8.cfg

#将kickstart文件，关联指定的YUM源和生成菜单列表
[root@centos7 ~]#cobbler profile add --name=CentOS-8.1_test --distro=CentOS-8.1-
x86_64 --kickstart= /var/lib/cobbler/kickstarts/centos8.cfg

8.删除默认的菜单列表

#删除默认的菜单列表
[root@centos7 ~]#cobbler profile remove --name=CentOS8.0-x86_64
