以手动方式安装和升级最新的 Linux 内核对于每个人来说都不是一件小事,甚至包括一些有经验的人也是如此。它需要对 Linux 内核有深入的了解。过去我们已经介绍了 UKUU(Ubuntu Kernel Upgrade Utility),它可以从 kernel.ubuntu.com 网站上自动检测最新的主线内核,并弹出一个不错的窗口界面进行安装。

Linux Kernel Utilities (LKU)提供一组 shell 脚本(三个 Shell 脚本),可以帮助用户从 kernel.org 获取并编译和安装最新的 Linux 内核,也可以从 kernel.ubuntu.com 获取安装最新的预编译的 Ubuntu 内核。甚至可以根据需要选择所需的内核(手动内核选择)。

该脚本还将根据 PGP 签名文件检查下载的归档文件,并且可以选择通用和低延迟版内核。

它可以删除或清除所有非活动的内核,并且不会为了安全目的留下备份的内核。强烈建议在执行此脚本之前重新启动一次。

  • compile_linux_kernel.sh :用户可以从 kernel.org 编译和安装所需的或最新的内核
  • update_ubuntu_kernel.sh :用户可以从 kernel.ubuntu.com 安装并更新所需或最新的预编译 Ubuntu 内核
  • remove_old_kernels.sh :这将删除或清除所有非活动内核,并且只保留当前加载的版本

kernel.org 有固定的发布周期(每三个月一次),发布的内核包括了新的功能,改进了硬件和系统性能。由于它具有标准的发布周期,除了滚动发布的版本(如 Arch Linux,openSUSE Tumbleweed 等),大多数发行版都不提供最新的内核。

如何安装 Linux Kernel Utilities (LKU)

正如我们在文章的开头所说的,它的 shell 脚本集只是克隆开发人员的 github 仓库并运行相应的 shell 文件来执行这个过程。


  1. $ git clone https://github.com/mtompkins/linux-kernel-utilities.git && cd linux-kernel-utilities

安装指定版本内核

为了测试的目的,我们将安装 Linux v4.4.10-xenial 内核。在安装新内核之前,我们需要通过 uanme -a 命令检查当前安装的内核版本,以便我们可以检查新内核是否可以安装。


  1. $ uname -a
  2. Linux magi-VirtualBox 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

根据上面的输出,我们的系统使用的是 4.4.0-21 通用内核。

只需运行 update_ubuntu_kernel.sh shell 脚本。第一次运行脚本时会检查是否满足所有的依赖关系,然后自动安装缺少的依赖项。它会检测系统使用的发行版,并检索 kernel.ubuntu.com 中可用的预编译内核。现在,从列表中选择你需要的内核并输入序号,然后按回车键,它将下载内核映像(linux-headers-4.4.10,linux-headers-4.4.10-xxx-generic 和 linux-image-4.4.10-xxx-generic)。

一旦内核镜像被下载,它将要求输入 sudo 密码来启动新内核的安装。

删除或清除旧内核

只需要运行 remove_old_kernels.sh shell 脚本即可删除或清除所有非活动状态的内核。


  1. $ ./remove_old_kernels.sh

  7. A reboot is recommended before running this script to ensure the current kernel tagged
  8. as the boot kernel is indeed registered and old kernels properly marked for removal.
  9. If you have just installed or modified your existing kernel and do not reboot before
  10. running this script it may render you system INOPERABLE and that would indeed suck.
