ubuntu14.04基于preseed批量分发环境搭建

Posted 2020-10-05

1.关闭防火墙

 

2.PXE环境准备

2.1服务器静态IP设置

    sudo vi /etc/network/interfaces

 

启动eth1网络

    sudo ifup eth1

 

2.2安装服务

2.2.1 安装dnsmasq作为dncp服务

sudo apt-get install dnsmasq

配置dhcp文件  

    sudo vi /etc/dnsmasq.conf

    bogus-priv

    filterwin2k

    interface=eth1

    dhcp-range=10.0.4.100,10.0.4.200,12h

    dhcp-host=08:00:27:0f:9b:1E,10.0.4.10

    dhcp-boot=pxelinux.0

    enable-tftp

    tftp-root=/var/ftpd

    dhcp-authoritative

创建tftp目录

    sudo mkdir –p /var/ftpd

启动dnsmasq服务

    sudo service dnsmasq start

2.2.3 安装apache2服务，提供需要安装的操作系统文件

sudo apt-get install apache2

浏览器验证httpd服务正常

 

apache2配置可以访问安装文件目录

    sudo vi sites-enabled/000-default.conf

 

    sudo vi /etc/apache2/apache2.conf

 

    sudo mkdir -p  /var/www/ubuntu

重启apache2目录

    sudo service apache2 restart

浏览器验证httpd服务正常

 

2.3.复制ubuntu14.04操作系统全目录，内核与启动镜像文件

挂载ubuntu –server.iso镜像     sudo mount /dev/cdrom /mnt

复制pxe启动文件和操作系统文件

    sudo cp  -vr /mnt/install/netboot/*  /var/ftpd

 

    cp –varf  /mnt/* /var/www/ubuntu

 

创建ks.cfg脚本

sudo touch /var/www/ubuntu/ks.cfg
