從 Redhat 引導分區解除安裝舊核心

接管了一個舊系統，發現/boot分區已滿 90%。

在網上搜尋了一番後，我發現安裝了較舊的核心，佔用了磁碟空間。

做rpm -qa | grep ^kernel | sort節目：

我刪除/解除安裝舊核心似乎是一種共識，但作為非系統管理員，我不太確定如何執行此操作。我怎麼知道要解除安裝哪些，我應該用rpm它來解除安裝？

uname -a顯示：

Linux 2.6.9-89.0.11.ELsmp #1 SMP Tue Sep 15 07:16:37 EDT 2009 i686 i686 i386 GNU/Linux

可能最安全的做法是使用yum erase <package>-<version>. 基本上，你在那裡有什麼，但.EL沒有必要包括在內。rpm -e如果由於某種原因 yum 不可用，您可以使用。

您要非常小心，不要刪除目前正在執行的核心。我注意到也有開發包。聽起來這些對您來說可能完全沒有必要，但我會先刪除最舊的版本，直到您對釋放的空間量感到滿意為止。

Yum 應該處理它，但還要確認引導條目已從 /etc/grub.conf 中刪除。
