公司每月新增几十台服务器，一台一台安装，实在是太累，通过以下方法，很容易在1小时内将60台系统安装好。
环境： 192.168.5.112 dhcp server,Ubuntu 10.04 192.168.5.150-200 dhcp client,pxe boot
所有配置在192.168.5.112上进行
1.安装dnsmasq apt-get install dnsmasq
2.配置dnsmasq vi /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
3.安装apache2并建立相关目录 apt-get install apache2 mkdir /var/www/ubuntu mount -o loop ~/ubuntu10.04.iso /mnt cp /mnt/preseed/ubuntu-server.seed /var/www/ubuntu cp -a /mnt/* /var/www/ubuntu cp -r /mnt/install/netboot/* /var/ftpd/
4.修改pxe配置 vi /var/ftpd/pxelinux.cfg/default label linux kernel ubuntu-installer/amd64/linux append ks=http://192.168.5.112/ubuntu/ks.cfg preseed/url=http://192.168.5.112/ubuntu/ubuntu-server.seed vga=normal initrd=ubuntu-installer/amd64/initrd.gz –
5.修改ks.cfg vi ks.cfg
#System language lang en_US #Language modules to install langsupport en_US #System keyboard

firewall –disabled skipx %packages @openssh-server
注： 生成密码 echo gaojinbo.com | openssl passwd -1 -stdin
6.修改ubuntu-server.seed配置 vi ubuntu-server.seed
# Suggest LVM by default. d-i partman-auto/init_automatically_partition string some_device_lvm d-i partman-auto/init_automatically_partition seen false # Always install the server kernel. d-i base-installer/kernel/override-image string linux-server # Install the Ubuntu Server seed. tasksel tasksel/force-tasks string server # Only install basic language packs. Let tasksel ask about tasks. d-i pkgsel/language-pack-patterns string # No language support packages. d-i pkgsel/install-language-support boolean false # Only ask the UTC question if there are other operating systems installed. d-i clock-setup/utc boolean false d-i clock-setup/ntp boolean false d-i apt-setup/use_mirror boolean false d-i netcfg/get_ipaddress string 127.0.0.1 d-i mirror/http://hostname string 127.0.0.1 d-i apt-setup/restricted boolean false
# No boot splash screen. d-i debian-installer/splash boolean false # Install the debconf oem-config frontend (if in OEM mode). d-i oem-config-udeb/frontend string debconf # Add the network and tasks oem-config steps by default. oem-config oem-config/steps multiselect language, timezone, keyboard, user, network, tasks
7.重启dnsmasq /etc/init.d/dnsmasq restart
很简单吧，7个步骤:)
完成！
，也和他共度。甚至连吵架也是重复的，
