Ubuntu 22 环境初始化

在搭建 HomeLab 测试使用过程中，可能会经常创建新的 Ubuntu 虚拟机，或初始化树莓派，记录一些常用的初始化配置

修改主机名

将主机名改为 homelab

hostnamectl hostname homelab

引入 SSH 公钥

  • 从本地导入

在本地执行，将公钥复制到要登录的机器上

ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]

修改 APT 源

将默认的 APT 源替换为清华的源

  • 修改镜像源
mv /etc/apt/sources.list /etc/apt/sources.list.backup

sudo bash -c "cat << EOF > /etc/apt/sources.list && apt update 
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-security main restricted universe multiverse
EOF"

然后使用 update 验证

apt-get update

安装常用软件

apt install -y --fix-missing curl vim git jq unzip net-tools zsh git-lfs

修改时区

使用 timedatectl 修改 /etc/timezone 文件配置，将时区改为UTC+8

sudo timedatectl set-timezone Asia/Shanghai

安装 zsh

  1. 安装 zsh 和 git
sudo apt install -y zsh git
  1. 添加 on-my-zsh
sudo sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
  1. 添加 autosuggestions 插件
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
  1. 修改 ~/.zshrc，启用 autosuggestions 插件，将 plugins=(git)替换为以下内容
plugins=(
git
zsh-autosuggestions
)
  1. 使配置生效
source ~/.zshrc

安装 Docker

  • docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
  • docker-compose
sudo apt install docker-compose -y

}
EOF
