isc-dhcp-server 状态失败:失败,结果“退出代码”

标签: ubuntu-server dhcp

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 failed 并显示消息“failed with result 'exit code'”。

enter image description here

是的,我确实配置了文件 /etc/dhcp/dhcp.conf 和 /etc/default/dhcpd.conf

我使用命令 journalctl -ex 查看了更多信息,显示下一个输入。但是我不知道输入说的是什么,因为我配置了接口和dhcp服务器。

我不知道如何解决这个问题。有人知道在这种情况下该怎么做。

这给了我解决方案:

$ sudo su
$ systemctl restart isc-dhcp-server.service
$ systemctl status isc-dhcp-server.service

它仍然像这里一样失败

检查进程ID;像 2167 和命令:

$ journalctl _PID=2167 {你的 PID 应该不同}

对我来说,它回馈了:

jun 17 11:30:52 wd-Latitude-E6530 sh[2193]: /etc/dhcp/dhcpd.conf line 57: subnet 10.10.10.1 netmask 255.255.255.0: bad subnet number/mask combination.
jun 17 11:30:52 wd-Latitude-E6530 sh[2193]: subnet 10.10.10.1 netmask 255.255.255.0

在 /etc/dhcp/dhcpd.conf 我需要更改

subnet 10.10.10.1 netmask 255.255.255.0

进入

subnet 10.10.10.0 netmask 255.255.255.0

所以 10.10.10.1 变成 10.10.10.0

$ systemctl restart isc-dhcp-server.service
$ systemctl status isc-dhcp-server.service

现在我开始工作了:

Active: active (running) since Thu 2021-06-17 11:50:51 CEST; 2s ago

您的问题可能有所不同,但 journalctl _PID=#### 会给您一些反馈,您可以从那里进行故障排除。

您好像缺少子网。我正在使用这个

[...]
subnet 10.10.10.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 10.10.10.255;
option routers 10.10.10.1;
option domain-name-servers 10.10.10.1;
range 10.10.10.3 10.10.10.250;
if exists user-class and option user-class = "iPXE" {
      filename "boot.ipxe";
  } else {
      filename "undionly.kpxe";

这是我的 iPXE 服务器的一部分。
