Ubuntu 提示 boot 空间不足的解决办法

Ubuntu 提示 boot 空间不足的解决办法

一、查看当前系统使用的内核相关信息。

root@gpu2:~# uname  -r
4.4.0-142-generic

二、查看安装的内核信息

root@gpu2:~# dpkg --get-selections | grep linux-image
linux-image-4.4.0-108-generic			deinstall
linux-image-4.4.0-109-generic			deinstall
linux-image-4.4.0-116-generic			deinstall
linux-image-4.4.0-119-generic			deinstall
linux-image-4.4.0-121-generic			deinstall
linux-image-4.4.0-124-generic			deinstall
linux-image-4.4.0-127-generic			deinstall
linux-image-4.4.0-128-generic			install
linux-image-4.4.0-130-generic			deinstall
linux-image-4.4.0-133-generic			deinstall
linux-image-4.4.0-134-generic			deinstall
linux-image-4.4.0-137-generic			deinstall
linux-image-4.4.0-138-generic			deinstall
linux-image-4.4.0-139-generic			deinstall
linux-image-4.4.0-141-generic			deinstall
linux-image-4.4.0-142-generic			install
linux-image-4.4.0-168-generic			deinstall
linux-image-4.4.0-169-generic			install
linux-image-4.4.0-170-generic			install
linux-image-4.4.0-21-generic			deinstall
linux-image-4.4.0-98-generic			deinstall
linux-image-extra-4.4.0-108-generic		deinstall
linux-image-extra-4.4.0-109-generic		deinstall
linux-image-extra-4.4.0-112-generic		deinstall
linux-image-extra-4.4.0-116-generic		deinstall

linux-image-extra-4.4.0-127-generic		deinstall
linux-image-extra-4.4.0-128-generic		install
linux-image-extra-4.4.0-130-generic		deinstall
linux-image-extra-4.4.0-133-generic		deinstall
linux-image-extra-4.4.0-134-generic		deinstall
linux-image-extra-4.4.0-137-generic		deinstall

linux-image-extra-4.4.0-139-generic		deinstall
linux-image-extra-4.4.0-141-generic		deinstall
linux-image-extra-4.4.0-142-generic		install
linux-image-extra-4.4.0-98-generic		deinstall
linux-image-generic				install

deinstall 表示该旧内核已经被删除了，需要的是删除不用的内核。

三、删除旧内核及解决问题

删除现在还在安装但是已经不再使用的内核

apt remove linux-image-4.4.0-128-generic linux-image-4.4.0-169-generic linux-image-4.4.0-170-generic linux-image-extra-4.4.0-128-generic linux-image-generic

运行命令 sudo /usr/sbin/update-grub 更新即可。

若在安装软件过程中提示系统中有多余的不被依赖的包，可以运行 sudo apt-get autoremove 以删除无用的包。

关闭自动更新内核

# cat /etc/apt/apt.conf.d/10periodic
APT::Periodic::Update-Package-Lists "0"; # 将1修改为0
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";

添加到ubuntu的基础配置中禁止自动更新内核文件

编写salt配置文件

/etc/apt/apt.conf.d/10periodic:
  file.managed:
    - user: root
    - group: root
    - mode: 644
    - source: salt://UBUNTU/base/10periodic

推送配置到所有机器上

  salt -G "os:Ubuntu" state.sls UBUNTU.base.init
