dhclient - 应用配置更改而无需重新启动

dhclient在配置文件 ( )上编辑一些配置后，/etc/dhcp/dhclient.conf更改似乎没有任何效果，直到我重新启动计算机。由于dhclient在后台运行，我相信该进程需要重新启动才能再次实际读取配置文件并应用所述更改。

实现这一目标的最佳方法是什么？

在dhclient手册页上我找到了以下选项：

-r            Release the current lease and stop the running  DHCP  client  as
              previously  recorded  in  the  PID file.  When shutdown via this
              method dhclient-script will be executed with the specific reason
              for calling the script set.  The client normally doesn't release
              the current lease as this is not required by the  DHCP  protocol
              but  some  cable ISPs require their clients to notify the server
              if they wish to release an assigned IP address.

如果我理解正确，这个选项将杀死dhclient，从而使其释放租约并在启动时再次读取配置文件（我不确定是否会像调用一样简单dhclient &）。

检查进程树，我还注意到dhclient是 的子进程network-manager。使用新配置重新开始运行会sudo service network-manager restart是一种更干净的方式吗？dhclient

重新激活连接。

例如通过nmcli connection up $NAMENetworkManager 或任何其他客户端。

您通常不会重新启动 NetworkManager。
