我的 centos 6 上缺少 /dev/dvd
我剛剛通過 USB dvd 刻錄機安裝了一個最小的 centos 6。它工作得很好。但現在我無法安裝 DVD 刻錄機。我什至找不到 /dev/dvd 設備。我想缺少驅動程序，但是我如何找到驅動程序？
系統的一些輸出。

我發現我的加固腳本在 /etc/modprobe.d 的一個 conf 文件中做了一個“黑名單 usb-storage”。我已經忘記了。
/dev/dvd是真正塊設備文件的符號連結。搜尋dmesgCD-ROM 設備的輸出。應該是類似的東西sr0orscd0。然後，您可以自己創建一個符號連結：sudo ln -s /dev/<dvd_device_name> /dev/dvd。
