Question

我在kea-dhcp4-server上安装了raspberry pi3 b+。我在/etc/kea/kea-dhcp4.conf上配置了所有内容，但是有问题。当我重启树莓派时，kea不再响应dhcp请求，因此我运行sudo service kea-dhcp4-server status，向我显示

我必须使用sudo mkdir /var/run/kea/创建文件夹，然后使用sudo service kea-dhcp4-service restart重新启动服务以使其起作用。但是，如果我再次重新启动树莓，则会再次出现该问题。

我该如何解决？

我也在Raspberry Pi上使用kea，我通过在systemd每次启动kea时创建/var/run/kea来解决了这个问题。

为此，请执行以下操作：

将kea systemd-unit文件复制到/ etc / systemd / system

cp /lib/systemd/system/kea-dhcp4-server.service /etc/systemd/system

复制此单位文件可确保在kea软件包的下一次更新中不会覆盖该文件。
在此文件的[Service]部分中添加以下内容：（/etc/systemd/system/kea-dhcp4-server.service）
```
ExecStartPre=/bin/mkdir -p /var/run/kea
```
此命令在systemd启动kea之前执行，它将创建丢失的目录。
执行systemctl daemon-reload。这将使systemd注意到新的配置。

重新启动，您应该一切顺利。
