+#### 使用 Homebrew/install
+
+Linuxbrew/install 现在已经废弃，被合并入 Homebrew/install。故可遵循「首次安装Homebrew」进行操作。
+
+在安装 Linuxbrew 前，需要安装 git。
+
+#### 直接安装 brew
+
+参考了 [https://docs.brew.sh/Homebrew-on-Linux](https://docs.brew.sh/Homebrew-on-Linux)
+
+直接使用以下脚本即可
+
+```
+git clone https://{{ site.hostname }}/git/homebrew/brew.git ~/.linuxbrew/Homebrew
+mkdir ~/.linuxbrew/bin
+ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin
+export HOMEBREW_CORE_GIT_REMOTE=https://{{ site.hostname }}/git/homebrew/homebrew-core.git
+export HOMEBREW_BOTTLE_DOMAIN=https://{{ site.hostname }}/homebrew-bottles
+eval $(~/.linuxbrew/bin/brew shellenv)
+brew update
+```
