/etc/network/interfaces 中没有主接口

/etc/network/interfaces 中没有主接口

我使用的是 Debian 9,想要设置静态 IP 地址。下列的本指南我应该找到一行以auto eth0in开头的行/etc/network/interfaces,但这里没有这样的东西。 Debian 9 中这些东西有改变吗?来自ip a我的网络接口wlo1- 或者这只是一个环回设备?

root@emerald:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback
root@emerald:~# ls /etc/network/interfaces.d/
root@emerald:~#

输出ip a

root@emerald:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether ec:9a:74:f3:72:a9 brd ff:ff:ff:ff:ff:ff
3: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 74:de:2b:9f:23:90 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.100/24 brd 192.168.1.255 scope global dynamic wlo1
       valid_lft 86377sec preferred_lft 86377sec
    inet6 fe80::76de:2bff:fe9f:2390/64 scope link 
       valid_lft forever preferred_lft forever

自 2009 年以来,Consistent Network Device Naming采用了命名惯例Ethernet adaptersLinux这就是为什么有eno1,没有eth0。并且由于缺少主网卡的配置/etc/networks/interfaces- 这很可能是因为您已经network-manager安装了。你可以看到一些相关的信息这里

如果您想使用/etc/network/intefaces,只需禁用或删除Network-Managereno1根据您的要求进行配置即可/etc/network/interfaces
