我正在 Ubuntu Server 20.04 LTS 上以模式 0(balanced-rr)设置两个 1 GB 以太网网卡的绑定。
绑定工作正常,因为它出现在分配的 IP 地址上,我可以通过此地址通过 SSH 进入它。但是,每个绑定的从属 NIC 仍然分配有一个 DHCP 地址。
我该如何设置才能让该绑定仅具有 IP 地址?
以下是我的设置方法:
sudo apt-get install ifenslave
sudo modprobe bonding
Edited /etc/modules to add "bonding"
最后,编辑 /etc/network/interfaces 以包含以下内容:(注意,在我编辑它之前它是空白的)
# bond0 is the bonded NIC, can be used like a normal NIC
auto bond0
iface bond0 inet static
address 10.16.0.91
gateway 10.16.0.1
netmask 255.255.0.0
#mode 0 is balanced-rr
bond-mode 0
bond-miimon 100
bond-slaves enp1s0 enp2s0
# enp1s0 connected to bond0
auto enp1s0
iface enp1s0 inet manual
bond-master bond0
# enp2s0 connected to bond0
auto enp2s0
iface enp2s0 inet manual
bond-master bond0
重启后,当我执行“ifconfig”时,它给出以下内容(我可以使用所有 3 个 IP)

如何防止从属接口获取自己的 DHCP 地址?
答案1
由于您将使用ifupdown
来控制网卡,因此netplan.io
不再需要使用。它将与ifupdown
导致额外 IP 地址等问题发生冲突。
sudo apt remove netplan.io
希望这可以帮助!
