PXE服务器安装–ARM架构机器

1. 基础环境准备

本章节pxe服务器采用centos8系统

系统镜像采用centos7.6-1810arm64 地址在文章最下面

首先，确保你的 CentOS 8 服务器已经安装了所需的服务，包括 tftp-server, httpd, dhcp-server, 以及 xinetd（用于 TFTP 服务）。

# 安装所需软件包
sudo dnf install -y dhcp-server tftp-server httpd xinetd syslinux

# 启动并设置自动启动 TFTP、HTTPD 和 DHCP 服务
sudo systemctl enable --now tftp xinetd dhcpd httpd

2，配置DHCP服务

DHCP 服务为网络中的客户端分配 IP 地址，并告知 PXE 引导文件的位置。

编辑 /etc/dhcp/dhcpd.conf，根据您的网络拓扑，配置如下：

subnet 192.168.137.0 netmask 255.255.255.0 {
    range 192.168.137.100 192.168.137.199;
    option subnet-mask 255.255.255.0;
    option routers 192.168.137.1;
    option domain-name-servers 8.8.8.8;
    default-lease-time 21600;
    max-lease-time 43200;
    next-server 192.168.137.100;
    filename "arm64/grubaa64.efi";
}

3，配置TFTP服务

service tftp

{

    socket_type             = dgram

    protocol                = udp

    wait                    = yes

    user                    = root

    server                  = /usr/sbin/in.tftpd

    server_args             = -s /var/lib/tftpboot

    disable                 = no

    per_source              = 11

    cps                     = 100 2

    flags                   = IPv4

}

4，配置PXE启动文件

[root@localhost ~]# mkdir –p /var/lib/tftpboot/arm64

[root@localhost ~]#  cp -avf /mnt/EFI/BOOT/*  /var/lib/tftpboot/arm64

[root@localhost ~]#  cp /mnt/images/pxeboot/vmlinuz  /var/lib/tftpboot/arm64

[root@localhost ~]#  cp /mnt/images/pxeboot/initrd.img  /var/lib/tftpboot/arm64

root@localhost ~]# ls /var/lib/tftpboot

root@localhost ~]# chmod –R 777 /var/lib/tftpboot

5,配置Grub引导文件

set default="1"

………………

set timeout=30

menuentry 'Install Centos7 Arm64' --class red --class gnu-linux --class gnu --class os {

        linux arm64/vmlinuz inst.ks=http://192.168.137.102/ks.cfg inst.repo=http://192.168.137.102/arm64 ro

        initrd arm64/initrd.img

}

6,配置KS文件 用于自动化安装

[root@localhost ~]# cp anaconda-ks.cfg /var/www/html/ks.cfg

[root@localhost ~]# vim /var/www/html/ks.cfg

#version=DEVEL

ignoredisk --only-use=sda

# System bootloader configuration

bootloader --location=mbr --boot-drive=sda

autopart --type=lvm

# Partition clearing information

clearpart --all --initlabel --drives=sda

# Use text mode install

# Use CDROM installation media

url --url=http://192.168.137.102/arm64

# Keyboard layouts

挂载镜像，并将内容拷贝到/var/www/html/arm64目录中

[root@localhost ~]# mount CentOS-7-aarch64-Everything-1810.iso  /mnt/cdrom

[root@localhost ~]# cp –avf /mnt/*  /var/www/html/arm64

[root@localhost ~]# chmod –R 777 /var/www/html/arm64

7.从PXE启动

1、 配置完成后重启服务

[root@localhost ~]# systemctl restart httpd.service

[root@localhost ~]# systemctl restart tftp.service

[root@localhost ~]# systemctl restart http.service

[root@localhost ~]# systemctl restart dhcpd.service
