CentOS 7 未检测到网络接口控制器

CentOS 7 最小化安装在远程服务器上。它有两个 NIC。与我处理过的其他服务器的设置相同。然而，其中之一似乎不起作用。

[root@home network-scripts]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d0:50:99:d3:10:2c brd ff:ff:ff:ff:ff:ff

[root@home network-scripts]# nmcli d
DEVICE  TYPE      STATE      CONNECTION
enp4s0  ethernet  connected  enp4s0
lo      loopback  unmanaged  --

然而，有 和ifcfg-enp4s0的ifcfg-eno1文件/etc/sysconfig/network-scripts/。

这是ifcfg-eno1：

# Generated by dracut initrd

当我跑步时：

[root@home network-scripts]# ifup eno1
Error: Connection activation failed: No suitable device found for this connection.

的输出

[root@home network-scripts]# lshw -class network

       resources: memory:a1300000-a131ffff

我不确定UNCLAIMED上面的意思。

我还尝试检查内核输出：

[root@home network-scripts]# dmesg | grep -i "Network Connection"
[    2.488019] igb 0000:04:00.0: Intel(R) Gigabit Ethernet Network Connection

和一些lspci输出：

[root@home net]# lspci | grep Connection
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (7) I219-LM (rev 10)
04:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03)

我不太确定这是否是驱动程序问题（以下是常问问题，但根据下面的输出，两个设备都安装了适当的驱动程序：

[root@home network-scripts]# /sbin/lspci -nn | grep -i net
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (7) I219-LM [8086:15bb] (rev 10)

如何判断操作系统存在软件问题还是物理端口/主板存在硬件问题？

我是否遗漏了一些完全明显的东西？

编辑：这是相关的驱动程序输出lspci -k：

00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (7) I219-LM (rev 10)
    Subsystem: ASRock Incorporation Device 15bb
    Kernel modules: e1000e

    Kernel modules: igb`

答案1

eno1 看起来不正确...这不是 centos7 命名接口的方式...

应该看起来像这样：

lshw -class network
