6.2. 为网络引导配置 DHCPv4 服务器

流程

1. 安装 DHCP 服务器：

   dnf install dhcp-server

2. 设置 DHCPv4 服务器。在 /etc/dhcp/dhcpd.conf 文件中输入以下配置。替换地址以匹配您的网卡。

   option architecture-type code 93 = unsigned integer 16;
   
   subnet 192.168.124.0 netmask 255.255.255.0 {
     option routers 192.168.124.1;
     option domain-name-servers 192.168.124.1;
     range 192.168.124.100 192.168.124.200;
     class "pxeclients" {
       match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
       next-server 192.168.124.2;
             if option architecture-type = 00:07 {
               filename "redhat/EFI/BOOT/BOOTX64.EFI";
             }
             else {
               filename "pxelinux/pxelinux.0";
             }
     }
     class "httpclients" {
       match if substring (option vendor-class-identifier, 0, 10) = "HTTPClient";
       option vendor-class-identifier "HTTPClient";
       filename "http://192.168.124.2/redhat/EFI/BOOT/BOOTX64.EFI";
     }
   }

3. 启动 DHCPv4 服务：

   # systemctl enable --now dhcpd
