Centos
我在讓 CentOS 辨識英特爾乙太網卡時遇到問題。請問有什麼建議嗎？
我有一個雙埠 Intel Pro/1000 (82571EB) PCIe 卡。我已安裝到執行 CentOS 6.2 x64 的 Dell PowerEdge 1950 中。檢測到卡並載入核心模組，但未在
/etc/sysconfig/network-scripts. 手動創建啟動腳本無濟於事；我收到有關未檢測到設備的錯誤。認為它可能是一張壞卡，我嘗試了另一張卡（相同型號），甚至將它放在不同的插槽中。沒有幫助。然而，奇怪的是這張卡在 PowerEdge 2950 上沒有問題。有人有什麼建議嗎？謝謝！

ip link. 我更改了手動創建的初始化腳本，界面現在通過ifup命令聯機。我自己也可以ping通。現在正在努力使其在正確的 VLAN 中聯機。我將再次用結果更新這篇文章。編輯：非常酷。現在開始工作了！我希望我知道為什麼a）設備名稱是“p2p1”和b）作業系統沒有自動添加初始化腳本？再次感謝您的建議！
請參閱這篇文章以了解為什麼它是 p2p1 - PCI 插槽 2，埠 1。http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming
我還不知道為什麼作業系統沒有自動添加正確的 ifcfg 文件。
您好，您需要刪除文件
/etc/udev/rules.d/70-persistent-net.rules正確檢測您的網卡。刪除文件後還要重新啟動電腦。重新啟動後從命令行進行設置以配置網路，如果這也不起作用，那麼您將必須為每個設備/介面創建一個文件。
