如何在Linux中检查内核的安装日期？

Question

我被要求检查已安装在Linux服务器中的内核的安装日期。有没有办法检查内核何时安装在Linux服务器上？

Answer 1

检查内核安装日期：

#rpm -qa --last | grep kernel

kernel-2.6.32-504.el6.x86_64                  Thu Feb 12 00:40:00 2015

有关内核包的更多信息：

# rpm -qi setup

Answer 2

打开终端并执行：

uname -a

你会得到类似的东西：

Linux 'user' 3.16.0.-23-generic #31-Ubuntu SMP Tue Oct 21 18:00:35 UTC 2014 i686 i686 i686 GNU/Linux

如您所见，安装日期如上所示。
