配置静态IP连接

配置IP

添加静态 IPv4 配置的网络连接,可使用以下命令:

nmcli connection add type ethernet con-name connection-name ifname interface-name ip4 address gw4 address

说明:
如果要添加 IPv6 地址和网关信息,使用 ip6 和 gw6 选项。

例如创建名为 net-static的静态连接配置文件,使用以下命令:

# nmcli con add type ethernet con-name net-static ifname enp3s0 ip4 192.168.0.10/24 gw4 192.168.0.254

还可为该设备同时指定 IPv6 地址和网关,示例如下:

# nmcli con add type ethernet con-name test-lab ifname enp3s0 ip4 192.168.0.10/24 gw4 192.168.0.254 ip6 abbe::**** gw6 2001:***::*
Connection 'net-static' (63aa2036-8665-f54d-9a92-c3035bad03f7) successfully added.

NetworkManager 会将其内部参数 ipv4.method 设定为 manual,将 connection.autoconnect 设定为yes,并将设置写入 /etc/sysconfig/network-scripts/ifcfg-my-office 文件,其中会将对应 BOOTPROTO 设定为 none,将 ONBOOT 设定为 yes。

设定两个 IPv4 DNS 服务器地址,使用以下命令:

# nmcli con mod net-static ipv4.dns "*.*.*.* *.*.*.*"

设置两个 IPv6 DNS 服务器地址,使用以下命令:

# nmcli con mod net-static ipv6.dns "2001:4860:4860::**** 2001:4860:4860::****"

激活连接并检查状态

激活新的网络连接,使用以下命令:

# nmcli con up net-static ifname enp3s0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)

检查这些设备及连接的状态,使用以下命令:

# nmcli device status

DEVICE      TYPE      STATE      CONNECTION
enp4s0      ethernet  connected  enp4s0
enp3s0      ethernet  connected  net-static
virbr0      bridge    connected  virbr0
lo          loopback  unmanaged  --
virbr0-nic  tun       unmanaged  --

查看配置的连接详情,使用以下命令(使用 -p, --pretty 选项在输出结果中添加标题和分段):

# nmcli -p con show net-static
