鞋匠PXE引导[PXE-E53:没有收到引导文件名]

Question

我的设置：

VirtualBox
DHCP/Cobbler VM server (CentOS 7)
PXE VM Client

'/etc/sysconfig/network-scripts/ifcfg-enp0s3'

DHCP/K13服务器(1台设备安装为NAT)TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=dhcp NAME=enp0s3 UUID=1b9314dd-2ad7-4bf5-bada-9fb0ca727526 DEVICE=enp0s3 ONBOOT=yes IPADDR=192.168.56.101 PREFIX=24

DHCP/Cobbler服务器/etc/dhcp/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;
     next-server                192.168.56.101;
     class "pxeclients" {
          } else {
                  filename "pxelinux.0";
          }
     }

}

DHCP/Cobbler服务器/etc/cobbler/ server‘

next_server: 192.168.56.101
server: 192.168.56.101

眼镜蛇检查

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

用于PXE的

安装.iso

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

PXE客户机

PXE-E53: No boot filename received

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

Answer 1

试试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";
        }

}

如果您的所有客户端启动BIOS模式，这应该可以工作。
