# 安装使用 Home Manager 前面简单提过,NixOS 自身的配置文件只能管理系统级别的配置,而用户级别的配置则需要使用 home-manager 来管理。 根据官方文档 [Home Manager Manual](https://nix-community.github.io/home-manager/index.html),要将 home manager 作为 NixOS 模块安装,首先需要创建 `/etc/nixos/home.nix`,配置方法如下: ```nix { config, pkgs, ... }: { # 注意修改这里的用户名与用户目录 home.username = "ryan"; home.homeDirectory = "/home/ryan"; # 直接将当前文件夹的配置文件,链接到 Home 目录下的指定位置 # home.file.".config/i3/wallpaper.jpg".source = ./wallpaper.jpg; # 递归将某个文件夹中的文件,链接到 Home 目录下的指定位置 # home.file.".config/i3/scripts" = { # source = ./scripts; # recursive = true; # 递归整个文件夹 # executable = true; # 将其中所有文件添加「执行」权限 # }; # 直接以 text 的方式,在 nix 配置文件中硬编码文件内容 # home.file.".xxx".text = '' # xxx # ''; # 设置鼠标指针大小以及字体 DPI(适用于 4K 显示器) xresources.properties = { "Xcursor.size" = 16; "Xft.dpi" = 172; }; # git 相关配置 programs.git = { enable = true; userName = "Ryan Yin"; userEmail = "xiaoyin_c@qq.com"; }; # 通过 home.packages 安装一些常用的软件 # 这些软件将仅在当前用户下可用,不会影响系统级别的配置 # 建议将所有 GUI 软件,以及与 OS 关系不大的 CLI 软件,都通过 home.packages 安装 home.packages = with pkgs;[ # 如下是我常用的一些命令行工具,你可以根据自己的需要进行增删 neofetch nnn # terminal file manager # archives zip xz unzip p7zip # utils ripgrep # recursively searches directories for a regex pattern jq # A lightweight and flexible command-line JSON processor yq-go # yaml processer https://github.com/mikefarah/yq exa # A modern replacement for ‘ls’ fzf # A command-line fuzzy finder # networking tools mtr # A network diagnostic tool iperf3 dnsutils # `dig` + `nslookup` ldns # replacement of `dig`, it provide the command `drill` aria2 # A lightweight multi-protocol & multi-source command-line download utility socat # replacement of openbsd-netcat nmap # A utility for network discovery and security auditing ipcalc # it is a calculator for the IPv4/v6 addresses # misc cowsay file which tree gnused gnutar gawk zstd gnupg # nix related # # it provides the command `nom` works just like `nix # with more details log output nix-output-monitor # productivity hugo # static site generator glow # markdown previewer in terminal btop # replacement of htop/nmon iotop # io monitoring iftop # network monitoring # system call monitoring strace # system call monitoring ltrace # library call monitoring lsof # list open files # system tools sysstat lm_sensors # for `sensors` command ethtool pciutils # lspci usbutils # lsusb ]; # 启用 starship,这是一个漂亮的 shell 提示符 programs.starship = { enable = true; settings = { add_newline = false; aws.disabled = true; gcloud.disabled = true; line_break.disabled = true; }; }; # alacritty 终端配置 programs.alacritty = { enable = true; env.TERM = "xterm-256color"; font = { size = 12; draw_bold_text_with_bright_colors = true; }; scrolling.multiplier = 5; selection.save_to_clipboard = true; }; programs.bash = { enable = true; enableCompletion = true; bashrcExtra = '' export PATH="$PATH:$HOME/bin:$HOME/.local/bin:$HOME/go/bin" ''; # set some aliases, feel free to add more or remove some shellAliases = { urldecode = "python3 -c 'import sys, urllib.parse as ul; print(ul.unquote_plus(sys.stdin.read()))'"; urlencode = "python3 -c 'import sys, urllib.parse as ul; print(ul.quote_plus(sys.stdin.read()))'"; httpproxy = "export https_proxy=http://127.0.0.1:7890; export http_proxy=http://127.0.0.1:7890;"; }; }; # This value determines the Home Manager release that your # configuration is compatible with. This helps avoid breakage # when a new Home Manager release introduces backwards # incompatible changes. # # You can update Home Manager without changing this value. See # the Home Manager release notes for a list of state version # changes in each release. home.stateVersion = "22.11"; # Let Home Manager install and manage itself. programs.home-manager.enable = true; } ``` 添加好 `/etc/nixos/home.nix` 后,还需要在 `/etc/nixos/flake.nix` 中导入该配置,它才能生效,可以使用如下命令,在当前文件夹中生成一个示例配置以供参考: ```shell nix flake new example -t github:nix-community/home-manager#nixos ``` 调整好参数后的 `/etc/nixos/flake.nix` 内容示例如下: ```nix { description = "NixOS configuration"; inputs = { nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable"; home-manager.url = "github:nix-community/home-manager"; home-manager.inputs.nixpkgs.follows = "nixpkgs"; }; outputs = inputs@{ nixpkgs, home-manager, ... }: { nixosConfigurations = { # 这里的 nixos-test 替换成你的主机名称 nixos-test = nixpkgs.lib.nixosSystem { system = "x86_64-linux"; modules = [ ./configuration.nix # 将 home-manager 配置为 nixos 的一个 module # 这样在 nixos-rebuild switch 时,home-manager 配置也会被自动部署 home-manager.nixosModules.home-manager { home-manager.useGlobalPkgs = true; home-manager.useUserPackages = true; # 这里的 ryan 也得替换成你的用户名 # 这里的 import 函数在前面 Nix 语法中介绍过了,不再赘述 home-manager.users.ryan = import ./home.nix; # 使用 home-manager.extraSpecialArgs 自定义传递给 ./home.nix 的参数 # 取消注释下面这一行,就可以在 home.nix 中使用 flake 的所有 inputs 参数了 # home-manager.extraSpecialArgs = inputs; } ]; }; }; }; } ``` 然后执行 `sudo nixos-rebuild switch` 应用配置,即可完成 home-manager 的安装。 安装完成后,所有用户级别的程序、配置,都可以通过 `/etc/nixos/home.nix` 管理,并且执行 `sudo nixos-rebuild switch` 时也会自动应用 home-manager 的配置。 `home.nix` 中 Home Manager 的配置项有这几种查找方式: - [Home Manager - Appendix A. Configuration Options](https://nix-community.github.io/home-manager/options.html): 一份包含了所有配置项的列表,建议在其中关键字搜索。 - [home-manager](https://github.com/nix-community/home-manager): 有些配置项在官方文档中没有列出,或者文档描述不够清晰,可以直接在这份 home-manager 的源码中搜索阅读对应的源码。
