[步骤] Linux 所有有 sudo 权限用户的显示
# cat /etc/sudoers | egrep -v "^#|Defaults logfile"| egrep -i ":.*all|/su" ; cat /etc/sudoers.d/* | egrep -v "^#|Defaults logfile"| egrep -i ":.*all|/su"
[步骤] 系统升级 (从 Fedora 42 升级到 Fedora 44)
步骤一:升级所有已安装的软件
# sudo dnf update
步骤二:安装 Fedora 升级软件
# sudo dnf install dnf-plugin-system-upgrade
步骤三:刷新所有现有版本的软件源
# sudo dnf upgrade --refresh
步骤四:下载升级所有所需的软件
# sudo dnf system-upgrade download --releasever=44
步骤五:重启并升级系统
# sudo dnf system-upgrade reboot
(注意:系统会重启,并在后台升级系统,这个步骤可能会持续很长一段时间,根据虚拟机的硬件性能而定)
[排错] 解决 DELL 物理服务器重启后在 BIOS 界面卡住并报错 “The system Configuration Check operation resulted in the following issue: Comm Error: Backplane 0.”
报错现象
DELL 物理服务器重启后在 BIOS 界面卡住并报错
报错代码
The system Configuration Check operation resulted in the following issue: Comm Error: Backplane 0.
解决方法
步骤一:升级系统 BIOS
(步骤略)
步骤二:重启物理服务器
(步骤略)
[排错] 解决系统启动后卡在 “A start job is running for /dev/mapper/…… (…… / no limit)”
报错代码案例
当系统启动时,系统会一直卡住,并在 console 口显示以下内容:
A start job is running for /dev/mapper/vg-lv_swap (...... / no limit)
案例原因分析
GRUB 参数 resume=/dev/mapper/vg-lv_swap 阻止了系统启动
解决方法
步骤一:重启系统
(步骤略)
步骤二:进入系统启动时的 GRUB 参数临时设置界面
当系统启动时出现内核列表时按下 “e” 键
步骤三:临时删除阻止系统启动的 GRUB 参数
在以 Linux 开头的这一行里删除以下内容:
...... resume=/dev/mapper/vg-lv_swap ......
(补充:这里以删除 GRUB 参数 resume=/dev/mapper/vg-lv_swap 为例)
步骤四:在临时删除阻止系统启动的 GRUB 参数后进入系统
同时按下 “ctrl” 键和 “x” 键
步骤五:使用 root 账号登陆系统
(步骤略)
步骤六:在系统里永久删除阻止系统启动的 GRUB 参数
# grubby --update-kernel ALL --remove-args "resume=/dev/mapper/vg-lv_swap"
(补充:这里以删除 GRUB 参数 resume=/dev/mapper/vg-lv_swap 为例)
