如何在Oracle Linux中將核心版本從6.8降級到6.7

Oracle Linux 6.7意外升級到6.8。需要降級到6.7。 我們如何編輯menu.lst以將其更改爲從較早的內核啓動？沒有用yum降級以下是最近輸出，如何在Oracle Linux中將核心版本從6.8降級到6.7

您的意思是內核版本降級爲3.8〜2.6？如果是的話，那很簡單。當電腦啓動時，在grub顯示時按下箭頭鍵 - 在5秒內完成，否則將啓動3.8。然後進入擴展選項 - 不管它如何顯示，除了「Oracle Linux Server Unbreakable Enterprise Kernel」外。然後選擇將是2.6內核的'Oracle Linux Server Red Hat Compatible Kernel'。如果這就是你所追求的，那麼在這裏發佈，我會添加關於如何總是引導到內核的進一步說明。 – bytefire

不，我想從3.8.13-68.3.4.el6uek而不是3.8.13-118.13.2.el6uek啓動，但我只能通過putty訪問這個服務器，沒有控制檯。因此，我只是在menu.lst上更改爲default = 2並重新啓動。不過謝謝你的支持。而且我還可以通過使用yum歷史記錄撤消ID將OS的等級從6.8降低到6.7。 – Dexpras

我能夠用下面的步驟來解決這個問題，

Eble到只需更改菜單上默認值從舊內核啓動.lst文件
使用以下步驟可以降級OS版舊版
