PVE 退出群集的操作步骤

停止cluster 服务

systemctl stop pve-cluster.service
systemctl stop corosync.service

设置本地模式

pmxcfs -l

删除corosync 配置文件

rm /etc/pve/corosync.conf
rm -rf /etc/corosync/*

重启cluster集群服务

killall pmxcfs
systemctl start pve-cluster.service

删除 WEB-UI 上的除当前 node 外的 node

cd /etc/pve/nodes
rm -rf node_name

windows 10 更新后恢复 manjaro 引导菜单

针对 manjaro ,但理论上适用于大多数 linux 系统。

先用 live 启动盘引导进入系统,按如下操作进行。

[manjaro@manjaro ~]$ lsblk -f

git 拉取所有分支的办法

git clone xxx
git branch -r | grep -v '\->' | while read remote; do git branch --track "${remote#origin/}" "$remote"; done
git fetch --all
git pull --all

alpine 中 apk add 很慢的解决办法

切换 alpine 源:

  • 阿里
sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
  • 科大镜像
sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories

设置 GOPROXY

bash 环境变量

echo "export GO111MODULE=on" >> ~/.profile
echo "export GOPROXY=https://goproxy.io" >> ~/.profile
source ~/.profile

KDE 中使用 MATE 键打开 latte-dock 的应用启动器

~/.config/kwinrc 文件中添加以下代码:

[ModifierOnlyShortcuts]
Meta=org.kde.lattedock,/Latte,org.kde.LatteDock,activateLauncherMenu

然后用以下命令重新加载KWin:

qdbus org.kde.KWin /KWin reconfigure

或者直接运行:

kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.lattedock,/Latte,org.kde.LatteDock,activateLauncherMenu"
qdbus org.kde.KWin /KWin reconfigure
