補鞋匠檢查

[root@dhcp ~]# cobbler check
No configuration problems found.  All systems go.

為 PXE 安裝 .iso

[root@dhcp ~]# mount -o loop CentOS-7-x86_64-Minimal-1708.iso /mnt/
[root@dhcp ~]# cobbler import --path=/mnt/ --name=CentOS-7

PXE客戶端

PXE-E53: No boot filename received

PXE-M0F: Exiting Intel PXE ROM. 
FATAL: Could not read from the boot medium! System halted.

嘗試 dhcpd.conf

ddns-update-style interim;

allow booting; allow bootp;

subnet 192.168.56.0 netmask 255.255.255.0 {
     option routers             192.168.1.5;
     option domain-name-servers 192.168.1.1;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.56.101 192.168.56.111;
     default-lease-time         21600;
     max-lease-time             43200;
     class "pxeclients" {
        match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
        next-server 192.168.56.101;
        filename "pxelinux.0";
        }

}

如果您的所有客戶端都啟動 BIOS 模式，這應該可以工作。
