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

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

4.修改pxe配置

vi /var/ftpd/pxelinux.cfg/default

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.
