我有一张双端口 Intel Pro/1000 (82571EB) PCIe 卡。我已将其安装到运行 CentOS 6.2 x64 的 Dell PowerEdge 1950 中。检测到了卡并加载了内核模块，但没有创建启动脚本/etc/sysconfig/network-scripts。手动创建启动脚本没有帮助；我收到有关未检测到设备的错误。
我觉得可能是卡坏了，于是尝试了另一张卡（相同型号），甚至将其放在不同的插槽中。但毫无效果。然而，奇怪的是，这张卡在 PowerEdge 2950 中运行正常。有人有什么建议吗？谢谢！

编辑：我看到设备在中显示为“p2p1” ip link。我修改了手动创建的初始化脚本，现在界面可以通过命令联机ifup。我也可以 ping 我自己。现在正在努力让它在正确的 VLAN 中联机。我将再次更新此帖子并附上结果。
编辑：非常酷。现在可以正常工作了！我希望知道为什么 a) 设备名称是“p2p1”以及 b) 操作系统没有自动添加初始化脚本？再次感谢您的建议！
答案1
请参阅此帖子以了解为什么它是 p2p1 - PCI 插槽 2，端口 1。http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming
我还不知道为什么操作系统没有自动添加正确的 ifcfg 文件。
答案2
你好你需要删除该文件
/etc/udev/rules.d/70-persistent-net.rules
正确检测您的网卡。删除文件后，还要重新启动您的机器。重新启动后，从命令行执行设置以配置网络，如果这也不起作用，那么您将必须为每个设备/接口创建一个文件。
请参阅博客。
答案3
根据我的经验，你应该使用以下命令：ip link、ifup
#ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:ac:0d:0e brd ff:ff:ff:ff:ff:ff
然后
#ifup eth0
就是这样。
