[HOMELAB] Talos安装指南

Talos 是一个不可变的Linux发行版，专门为K8S做了优化，国内暂时还没有系统的教程安装，这里给一个教程进行安装。

安装 Brew

国内的 Homebrew 镜像有很多，但是阿里云镜像的方便安装，可以按照下面的教程进行安装。

1. 设置镜像为阿里源，并且设置环境变量

   1 2 3 4 5 6

   # 临时替换 export HOMEBREW_INSTALL_FROM_API=1 export HOMEBREW_API_DOMAIN="https://mirrors.aliyun.com/homebrew-bottles/api" export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/brew.git" export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/homebrew-core.git" export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.aliyun.com/homebrew/homebrew-bottles"

2. 安装 Homebrew

   1 2 3 4 5 6 7

   # 从阿里云下载安装脚本并安装 Homebrew git clone https://mirrors.aliyun.com/homebrew/install.git brew-install /bin/bash brew-install/install.sh rm -rf brew-install # 验证是否完成安装了 brew -v

3. 设置homebrew安装源为阿里源

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

   # 永久替换 # bash 用户 echo 'export HOMEBREW_API_DOMAIN="https://mirrors.aliyun.com/homebrew-bottles/api"' >> ~/.bash_profile echo 'export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/brew.git"' >> ~/.bash_profile echo 'export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/homebrew-core.git"' >> ~/.bash_profile echo 'export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.aliyun.com/homebrew/homebrew-bottles"' >> ~/.bash_profile source ~/.bash_profile brew update # zsh 用户 echo 'export HOMEBREW_API_DOMAIN="https://mirrors.aliyun.com/homebrew-bottles/api"' >> ~/.zshrc echo 'export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/brew.git"' >> ~/.zshrc echo 'export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.aliyun.com/homebrew/homebrew-core.git"' >> ~/.zshrc echo 'export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.aliyun.com/homebrew/homebrew-bottles"' >> ~/.zshrc source ~/.zshrc brew update

4. 将 Brew 添加到 PATH 中

   1 2 3 4 5 6 7 8 9

   # 如果是 Bash 执行下面的命令 test -d ~/.linuxbrew && eval "$(~/.linuxbrew/bin/brew shellenv)" test -d /home/linuxbrew/.linuxbrew && eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)" echo "eval \"\$($(brew --prefix)/bin/brew shellenv)\"" >> ~/.bashrc # 如果是 ZSH 需要执行下面的命令 test -d ~/.linuxbrew && eval "$(~/.linuxbrew/bin/brew shellenv)" test -d /home/linuxbrew/.linuxbrew && eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)" echo "eval \"\$($(brew --prefix)/bin/brew shellenv)\"" >> ~/.zshrc

5. 卸载 brew （如果后续需要的话）

   1 2 3 4

   # 从阿里云下载安装脚本并安装 Homebrew git clone https://mirrors.aliyun.com/homebrew/install.git brew-install /bin/bash brew-install/uninstall.sh rm -rf brew-install

# 查看当前集群的节点信息
talosctl cluster show

# 进入节点的 dashboard，观察 READY 为 Running 即可
talosctl dashboard --nodes 10.5.0.2

# 添加当前集群的配置到配置(context)
talosctl config nodes 10.5.0.2 10.5.0.3
talosctl config info
