art*_*aag 5 dhcp ubuntu-server
我使用 isc-dhcp-server 设置了一个简单的 dhcp-server,但是当我启动该服务时,状态为失败,并显示消息“失败,结果为‘退出代码’”。
是的,我确实配置了文件 /etc/dhcp/dhcp.conf 和 /etc/default/dhcpd.conf
journalctl -ex我使用显示下一个输入的命令检查了更多信息。但我不知道输入的内容是什么,因为我配置了接口和 dhcp 服务器。
我不知道要做什么来解决这个问题。有人知道在这种情况下做什么。

这给了我解决方案:
\n$ sudo su\n$ systemctl restart isc-dhcp-server.service\n$ systemctl status isc-dhcp-server.service\nRun Code Online (Sandbox Code Playgroud)\n它仍然像这里一样失败

\n$ journalctl _PID=2167 {你的PID应该不同}
对我来说它回馈了:

\n您似乎缺少子网。我正在用这个
