一、安装：

不能在root下运行

$sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
- Add Linuxbrew to your PATH

    PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"

- We recommend that you install GCC by running:

    brew install gcc

- Run `brew help` to get started

- Further documentation: 

    https://docs.brew.sh

Warning: /home/ubuntu/.linuxbrew/bin is not in your PATH.

设置路径：

$export PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"

这里参考设置环境变量
linux 修改配置文件

二、卸载：

$/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" 

The following possible Homebrew files were not deleted:

/home/linuxbrew/.linuxbrew/share/

/home/linuxbrew/.linuxbrew/etc/

/home/linuxbrew/.linuxbrew/lib/

/home/linuxbrew/.linuxbrew/var/

You may wish to remove them yourself.

需要手动删除文件夹：

$rm -r -f /home/linuxbrew/.linuxbrew

三、更换源

brew默认的源速度太慢了，可以替换成国内的清华大学提供的源

1.Homebrew 的 formula 索引的镜像（即brew update时所更新内容）
替换brew.git
这里$(brew --repo) 是/home/linuxbrew/.linuxbrew/Homebrew
$ cd "$(brew --repo)"
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
替换homebrew-core.git
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
$ brew update

2. Homebrew 二进制预编译包的镜像(注： 2.1 2.2 任选其一)    
 2.1 临时替换(关闭终端再次打开终端时配置失效，使用默认配置)   
 export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles    
 2.2 长期替换(建议使用此项配置)  
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles'>>   ~/.bash_profile   
source ~/.bash_profile  
 #执行.bash_profile脚本让配置即时生效

注意：
linux 必须先安装gcc，很多软件编译还是得用apt下载gcc和g++，make,cmake,还有环境配置，不是很好用
