1、图形化最小安装debian7.5操作系统
2、更改debian的apt源配置文件/etc/apt/sources.list
root@duan:~# cat /etc/apt/sources.list deb http://ftp.de.debian.org/debian wheezy main contrib non-free deb-src http://ftp.de.debian.org/debian wheezy main contrib non-free
3、更新apt,并配置网络安装所需要的服务(DHCP、TFTP、HTTP)
root@duan:~# apt-get update root@duan:~# apt-get install isc-dhcp-server tftp-hpa apache2
修改相关配置文件并重启相关服务
##### DHCP ##### cat /etc/dhcp/dhcpd.conf default-lease-time 600; max-lease-time 7200; allow booting; subnet 192.168.100.0 netmask 255.255.255.0 { range 192.168.100.128 192.168.100.253; option broadcast-address 192.168.100.255; option routers 192.168.100.100; # our router option domain-name-servers 192.168.100.100; # our router, again filename "pxelinux.0"; # (this we will provide later) } group { next-server 192.168.100.100; # our Server host tftpclient { filename "pxelinux.0"; # (this we will provide later) } }
###### TFTP ##### root@debian:~# cat /etc/default/tftpd-hpa # /etc/default/tftpd-hpa TFTP_USERNAME="tftp" TFTP_DIRECTORY="/var/lib/tftpboot" TFTP_ADDRESS="0.0.0.0:69" TFTP_OPTIONS="--secure"
##### HTTP ##### root@duan:~# mkdir -p /var/www/debian/ root@duan:~# mkdir -p /var/www/pxe/ root@duan:/var/www/pxe# ls /var/www/pxe preseed.cfg root@duan:/var/www/pxe# ls /var/www/debian/ autorun.inf dists g2ldr isolinuxREADME.html README.txt boot doc g2ldr.mbr md5sum.txtREADME.mirrors.html setup.exe css efi install picsREADME.mirrors.txt tools debian firmware install.amd poolREADME.source win32-loader.ini root@duan:~# df -h Filesystem Size Used Avail Use% Mounted on rootfs 38G 7.7G 29G 22% / udev 10M 0 10M 0% /dev tmpfs 100M 660K 99M 1% /run /dev/disk/by-uuid/7b490b3d-5fe2-4929-bd37-7d97f8932890 38G 7.7G 29G 22% / tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 541M 336K 541M 1% /run/shm /dev/loop0 3.7G 3.7G 0 100% /var/www/debian
注:此处http的主要作用,就是将debian镜像及无人值守安装配置文件preseed.cfg,通过http服务提供给PXE客户端。
4、配置pxe开机引导文件
下载debian网络引导文件
root@duan:~# wget http://ftp.debian.org/debian/dists/Debian7.5/main/installer-amd64/current/p_w_picpaths/netboot/netboot.tar.gz
将其解压到tftp根目录下
root@duan:~# tar -zxvf netboot.tar.gz -C /var/lib/tftpboot
将其中 pxelinux.0 pxelinux.cfg两个文件拷贝到tftp根目录下
root@duan:/var/lib/tftpboot# ls debian-installer pxelinux.0 pxelinux.cfg
编辑开机引导文件pxelinux.cfg/default
root@debian:/var/lib/tftpboot# cat pxelinux.cfg/default # D-I config version 2.0 include debian-installer/amd64/boot-screens/menu.cfg default debian-installer/amd64/boot-screens/vesamenu.c32 prompt 1 timeout 3 DEFAULT wheezy_amd64 LABEL wheezy_amd64 kernel debian-installer/amd64/linux append vga=normal initrd=debian-installer/amd64/initrd.gz auto=true interface=auto netcfg/dhcp_timeout=60 netcfg/choose_interface=auto priority=critical url=http://192.168.100.100/pxe/preseed.cfg DEBCONF_DEBUG=5 IPAPPEND 2
编辑debian无人值守安装配置文件

注意:用dvd搭建的局域网apt-mirror镜像源,在安装过程中需要Release及gpg认证,由于我们并不使用官方源安装系统,而我们自己的源又不含有公开的签名,在默认情况下,选择我们自己配置的源会出现错误,类似(在安装过程中可以按Ctrl+Alt+F4切换到第四个虚拟控制台,查看安装信息。按Ctrl+Alt+F1切换回安装界面)
dists/wheezy/Release is unsigned.
当时看到这个报错,我就跑偏了,在GPG加密这一块尝试了N久,还尝试了其他的无人值守FAI部署,其实要解决这个报错,我们只需要将两个配置文件做更改为如下即可:
root@duan:/var/lib/tftpboot/debian-installer/amd64/boot-screens# cat txt.cfg default install label install menu label ^Install menu default kernel debian-installer/amd64/linux append vga=788 initrd=debian-installer/amd64/initrd.gz debian-installer/allow_unauthenticated=true -- quiet
cat /var/www/pxe/preseed.cfg |grep unauthenticated # apt will complain about the unauthenticated repository and so the d-i debian-installer/allow_unauthenticated string true
也就是说忽略签名认证
5、安装
开机F12,并对preseed.cfg各选项做修改。
希望本篇文章能对大家有一定的启示,让大家尽量少走弯路,并实现在没有外网的情况下,快速完成debian的批量网络安装部署。
另:解决Debian PXE方式安装找不到硬盘的问题
是由于网络启动模式的initrd.gz中并未包含对应的驱动模块,导致无法发现硬盘。可以拿DVD光盘中install[.arch]目录下的initrd解压后获取驱动模块,与网络方式(netboot)安装的initrd合并后,重新制作新的initrd文件。
1. gunzip解压dvd中的initrd.gz并重命名为initrd-dvd
2. gunzip解压netboot中的initrd.gz并重命名为initrd-net
3. 解包initrd-dvd到dvd目录
mkdir dvd
cd dvd
cpio -i < ../initrd-dvd
4. 解包initrd-net到net目录
mkdir net
cd net
cpio -i < ../initrd-net
5. 将dvd版本中的驱动复制到net版(请调整目录名称)
cd ../dvd/lib/modules/3.2.0-4-amd64/kernel/drivers/
cp -a * ../../../../../../net/lib/modules/3.2.0-4-amd64/kernel/drivers/
6. 重新打包initrd
cd ../../../../../../net/#进入netboot解包目录
find | cpio -R 0:0 -o -H newc > ../initrd
cd ..
gzip initrd
7. 复制initrd.gz到tftp目录测试PXE引导,Enjoy!
