我尝试使用 nmcli 将静态 IP 分配给我的 Ubuntu 16.04 服务器，它有效，但它仍然保留原始 IP 作为“辅助”IP。我不知道如何摆脱它。 10.163.148.36是服务器的原始IP，10.163.148.194是我希望它切换到的新IP。我使用以下 nmcli 命令来设置 IP 地址：
nmcli connection modify 'Wired connection 1' ipv4.addresses '10.163.148.194/24' ipv4.gateway '10.163.148.2' ipv4.method 'manual' ipv4.ignore-auto-dns 'yes' connection.autoconnect 'yes' ipv4.dns '10.10.10.10 10.20.10.10'
记下 ens160 接口的两个 IP 地址。
aruba@ubuntu:~$ ip a

答案1
在“Red Hat”中，语法如下：
nmcli con mod "Wired connection 1" -ipv4.addresses "10.163.148.194"
您只需在您的属性前添加一个减号
它在 Ubuntu 中也可能像这样工作……？
答案2
我也遇到过同样的情况，除了使用“ip addr del”命令删除旧IP之外，我没有找到任何其他解决方案，例如：
ip addr del 10.163.148.36/24 dev ens160
答案3
这是在 Fedora 29 中对我有用的（在 RHEL/CentOS 中可能工作得很好）：
nmcli con mod ens192 ipv4.addresses "" ipv4.gateway ""
然后只需弹起界面即可拾取更改：
nmcli con down ens192; nmcli con up ens192
答案4
我在 Fedora 安装中使用以下命令将其删除
nmcli con mod end192 ipv4.method manual
这将停止 DHCP 连接并且仅分配已配置的静态 IPv4 地址。
