在raspberry重新启动之后，kea-dhcp4 4-服务器无法工作。
我已经在我的raspberry pi3 b+上安装了raspberry pi3 b+。我配置了/etc/kea/kea-dhcp4.conf上的所有内容，但存在一个问题。当我重新启动覆盆子kea不再响应dhcp请求时，我运行了sudo service kea-dhcp4-server status，它向我展示了

我怎么才能修好它？

我还在Raspberry Pi上使用kea，每次系统启动kea时，我都通过创建/var/run/kea来解决这个问题。
要做到这一点，请执行以下操作：
- 将kea单元文件复制到/etc/systemd/system
cp /lib/systemd/system/kea-dhcp4-server.service /etc/systemd/system
复制此单元文件，确保它不会被kea包的下一次更新覆盖。。
- 将以下内容添加到该文件的
[Service]-Section中：(/etc/systemd/system/kea-dhcp4-server.service)
ExecStartPre=/bin/mkdir -p /var/run/kea
这个命令在systemd启动kea之前执行，它将创建缺少的目录.
- 执行
systemctl daemon-reload。这将使系统注意到新的configuration.
重新启动，你就可以走了。
