+Binary cache 的镜像位于 <https://{{ site.host }}/nix-channels/store>，与 channel 同步更新。

 以优先选择镜像，备选源站为例，选择以下配置之一：

 - 单独安装的 Nix：编辑配置文件添加或修改如下项（通常系统配置在 `/etc/nix/nix.conf`，用户配置在 `~/.config/nix/nix.conf`）：

    ```plain
-    substituters = https://mirrors.tuna.tsinghua.edu.cn/nix-channels/store https://cache.nixos.org/
+    substituters = https://{{ site.host }}/nix-channels/store https://cache.nixos.org/
    ```

 - NixOS 和 nix-darwin 使用如下配置：

    ```nix
-    nix.binaryCaches = [ "https://mirrors.tuna.tsinghua.edu.cn/nix-channels/store" "https://cache.nixos.org/" ];
+    nix.binaryCaches = [ "https://{{ site.host }}/nix-channels/store" "https://cache.nixos.org/" ];
    ```

 - NixOS 19.09 及以后版本和 nix-darwin 中系统会自动配置备选源站，也可用如下配置：

    ```nix
-    nix.binaryCaches = [ "https://mirrors.tuna.tsinghua.edu.cn/nix-channels/store" ];
+    nix.binaryCaches = [ "https://{{ site.host }}/nix-channels/store" ];
    ```

 ### Nixpkgs channel

-Channel 的镜像位于 <https://mirrors.tuna.tsinghua.edu.cn/nix-channels/> 目录下，使用方式与 <https://nixos.org/channels/> 相同。
+Channel 的镜像位于 <https://{{ site.host }}/nix-channels/> 目录下，使用方式与 <https://nixos.org/channels/> 相同。

 单独安装的 Nix 替换 `nixpkgs-unstable` 命令如下：

 ```console
-$ nix-channel --add https://mirrors.tuna.tsinghua.edu.cn/nix-channels/nixpkgs-unstable
+$ nix-channel --add https://{{ site.host }}/nix-channels/nixpkgs-unstable
 $ nix-channel --update
 ```

 替换 NixOS channel 命令如下（以 root 执行，将 `19.09` 替换为系统版本）：

 ```console
-# nix-channel --add https://mirrors.tuna.tsinghua.edu.cn/nix-channels/nixos-19.09
+# nix-channel --add https://{{ site.host }}/nix-channels/nixos-19.09
 # nix-channel --update
