无法安装tftpd-hpa

Question

我试图通过集群控制节点运行apt-get install dnsmasq pxelinux syslinux-common，并在安装时继续获取此错误。

Job for tftpd-hpa.service failed because the control process exited with error code.
See "systemctl status tftpd-hpa.service" and "journalctl -xe" for details.
invoke-rc.d: initscript tftpd-hpa, action "start" failed.

这是ifconfig的输出

我的总体目标是让集群PXE的节点启动，并连接到位于控制节点上的停靠群。现在，我按照这里显示的说明：https://manski.net/2016/09/pxe-server-on-existing-network-dhcp-proxy-on-ubuntu/。如何传递上述错误？有更简单的方法吗？

编辑:我在控制节点上使用20.04，所有其他节点都被设置为PXE引导。

Answer 1

您是否先安装了另一个tftp服务器？错误似乎很明显，在tftp端口(69)上正在侦听其他什么东西。

in.tftpd[15975]: cannot bind to local IPv4 socket: Address already in use

要查看在端口上侦听的内容，请尝试

ss -lpn | grep :69
