利用cobbler 实现系统自动化安装

Posted 2021-02-17

1 安装包和配置服务

root:~# yum install cobbler  dhcp -y
root:~# systemctl enable tftp dhcpd httpd cobblerd
root:~# systemctl start tftp  httpd cobblerd

2 修改cobbler 配置文件

vim /etc/cobbler/settings
server: cobblerIP  384

next_server: cobblerIP 272 

default_password_crypted: "$1$VBqc7U0W$F2qhI5oZwR8chJBU.mAly1"   101

manage_dhcp: 1    242 #可自动配置dhcp

3 配置dhcp服务

root:~# vim /etc/cobbler/dhcp.template
subnet 192.168.64.0 netmask 255.255.255.0 {
     option routers             192.168.64.254;

4导入安装源文件

将光盘挂载好

root:~# df

查看现有安装选项

root:~# cobbler profile list
   Centos-6.10-x86_64

现在已经可以自动化安装了，不过cobbler默认配置文件为最小化安装，想要自定义的花要修改配置文件

Centos 7.0下使用system-config-kickstart

修改CentOS-Base.repo

[base]                     修改 ---------->[development]  
name=CentOS-$releasever - Base
root:~# yum install -y system-config-kickstart.noarch
root:~  # env LANG=zh_CN.UTF-8 system-config-kickstart #生成自定义配置文件

将所有选项选完即可左上角保存
