从 Redhat 启动分区卸载旧内核

接管旧系统后发现/boot分区已满 90%。

在网上搜索后，我发现安装了较旧的内核，占用了磁盘空间。

似乎大家都一致认为我应该删除/卸载旧内核，但作为非系统管理员，我不太清楚该怎么做。我怎么知道要卸载哪些内核，我该怎么做rpm？

uname -a显示：

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

答案1

最安全的做法可能是使用yum erase <package>-<version>。基本上，上面有，但.EL没有必要包含 。rpm -e如果由于某种原因 yum 不可用，您可以使用。

你要非常小心，不要删除当前正在运行的内核。我注意到还有 devel 包。听起来这些对你来说可能完全没有必要，但我建议先删除最旧的版本，直到你对释放的空间量感到满意为止。

Yum 应该会处理这个问题，但也要确认启动项已从 /etc/grub.conf 中删除。

答案2

我本周遇到了这个问题。我发现一个启用了 yum 自动更新的系统。多年来，应用了多个内核更新，最终填满了 /boot。使用 记下您的内核版本uname -a。运行列出已安装的各种内核包。对要删除的版本/包rpm -qa | grep kernel执行。yum erase

[root@xxxx ~]#  rpm -qa | grep kernel
