自动化部署之（二）ubuntu无人值守安装系统

ubuntu无人值守安装系统，用于批量网络安装Ubuntu和debian

环境：Ubuntu-desktop(ip:192.168.56.11)

安装软件

apt install dnsmasq apache2 system-config-kickstart

配置dnsmasq

vim /etc/dnsmasq.conf

bogus-priv
filterwin2k 
interface=eth0
dhcp-range=192.168.5.150,192.168.5.250,12h  
dhcp-boot=pxelinux.0  
enable-tftp  
tftp-root=/var/ftpd  
dhcp-authoritative 

创建必要的目录

mkdir /var/ftpd
mkdir /var/www/ubuntu

挂载安装介质

mount /dev/cdroom /mnt
cp /mnt/* /var/www/ubuntu -arf

将网络启动文件复制到网络引导目录

cp /var/www/ubuntu/install/netboot/* /var/ftpd -arf/

修改apache2配置文件

vim /etc/apache2/sites-enabled/000-default.conf

DocumentRoot /var/www
#这里只给出了关键配置

运行system-config-kickstart生成ks.cfg文件

编辑响应文件ks.cfg

vim /var/www/ks.cfg

编辑引导文件

vim /var/ftpd/pxelinux.cfg/default

path ubuntu-installer/amd64/boot-screens/
include ubuntu-installer/amd64/boot-screens/menu.cfg
default ubuntu-installer/amd64/boot-screens/vesamenu.c32
default install
label install
    kernel ubuntu-installer/amd64/linux
    append ks=http://192.168.56.11/ks.cfg initrd=ubuntu-installer/amd64/initrd.gz --
prompt 0
timeout 0

启动相关服务

systemctl start apache2
systemctl start dnsmasq

若安装出现如下错误

请在ubuntu-installer/amd64/boot-screens/txt.cfg里，append加入如下一行配置

live-installer/net-image=http://192.168.56.11/ubuntu/install/filesystem.squashfs clock-setup/ntp=false ip=dhcp ksdevice=bootif

解决图片所示的错误

vim /var/ftpd/ubuntu-installer/amd64/boot-screens/txt.cfg

default install
label install
    menu label ^Install
    kernel ubuntu-installer/amd64/linux
    append ks=http://192.168.56.11/ks.cfg vga=788 initrd=ubuntu-installer/amd64/initrd.gz live-installer/net-image=http://192.168.56.11/ubuntu/install/filesystem.squashfs clock-setup/ntp=false ip=dhcp ksdevice=bootif --- quit
