ubuntu16 kickstart pxe 安装系统

前端之家收集整理的这篇文章主要介绍了ubuntu16 kickstart pxe 安装系统前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

环境
PXE网段:172.25.151.0/24
PXE网关:172.25.151.1
PXE服务器地址:172.25.151.254
PXE服务器系统 : ubuntu 16.04
DHCP地址池:172.25.151.240~172.25.151.253
PXE安装镜像IOS:ubuntu-16.04.4-server-amd64
挂载目录:/mnt

首先:设置网卡1 以pxe方式启动
最后:安装完成后恢复默认启动方式。

配置:
1.安装dhcp服务器

apt-get install isc-dhcp-server

修改网卡

root@ubuntu-pxe:~# cat /etc/default/isc-dhcp-server  | grep -v "^#" | grep -v "^$"
INTERFACES="enp2s0"

配置dhcp地址池

root@ubuntu-pxe:~# cat /etc/dhcp/dhcpd.conf  | grep -v "^#" | grep -v "^$"                       
ddns-update-style none;
log-facility local7;
subnet 192.168.151.0 netmask 255.255.255.0 {
  range 192.168.151.240 192.168.151.253;
  option domain-name-servers 192.168.111.2;
  option subnet-mask 255.255.255.0;
  option routers 192.168.151.1;
  option broadcast-address 192.168.151.255;
  default-lease-time 600;
  max-lease-time 7200;
}
allow booting;
allow bootp;
option option-128 code 128 = string;
option option-129 code 129 = text;
next-server 192.168.151.254;
filename "pxelinux.0";

重启dhcp服务

systemctl restart isc-dhcp-server
@H_301_28@
  • 安装tftp服务
  • apt-get install tftpd-hpa

    修改配置

    root@ubuntu-pxe:~# cat /etc/default/tftpd-hpa  | grep -v "^#" | grep -v "^$"                    
    TFTP_USERNAME="tftp"
    TFTP_DIRECTORY="/var/lib/tftpboot"
    TFTP_ADDRESS="0.0.0.0:69"
    TFTP_OPTIONS="--secure"
    RUN_DAEMON="yes"
    OPTIONS="-l -s /var/lib/tftpboot"

    3.安装Apache2

    apt-get install apache2

    4.拷贝及修改所需文件

    mkdir /var/www/html/ubuntu
    rm -fr /var/www/html/index.html
    mount /dev/cdrom /mnt
    cp -r /mnt/* /var/www/html/ubuntu/
    cp -r /var/www/html/ubuntu/install/netboot/* /var/lib/tftpboot/

    5.生成ks.cfg 文件文件内容见最后)
    6.修改部分配置
    在命令行root家目录
    cp ks.cfg /var/www/html/
    vim /var/www/html/ks.cfg #添加安装的软件包
    skipx #下面添加需要安装的软件包
    %packages
    openssh-server
    编辑txt.cfg

    root@ubuntu-pxe:~# cat /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg | grep -v "^#" | grep -v "^$"                       
    default install
    label install
            menu label ^Install
            menu default
            kernel ubuntu-installer/amd64/linux
            append net.ifnames=0 AND biosdevname=0 ks=http://192.168.151.254/ks.cfg vga=788 initrd=ubuntu-installer/amd64/initrd.gz live-installer/net-image=http://192.168.151.254/ubuntu/install/filesystem.squashfs
    label cli
            menu label ^Command-line install
            kernel ubuntu-installer/amd64/linux
            append tasks=standard pkgsel/language-pack-patterns= pkgsel/install-language-support=false vga=788 initrd=ubuntu-installer/amd64/initrd.gz --- quiet

    编辑文件default

    root@ubuntu-pxe:~# cat /var/lib/tftpboot/pxelinux.cfg/default | grep -v "^#" | grep -v "^$"                                                             
    path ubuntu-installer/amd64/boot-screens/
    include ubuntu-installer/amd64/boot-screens/menu.cfg
    default ubuntu-installer/amd64/boot-screens/vesamenu.c32
    prompt 0
    timeout 100

    接下来就可以安装系统了

    hostname SH$NAME
    echo SH$NAME >/etc/hostname
    NET=$(/sbin/ifconfig |grep -o "inet addr:192.168[^ ]*" |awk -F. '{print $3}')

    7。 以网络模式启动一台服务器进行装机

    过程略。。。
