HomeBrew更新和安装软件缓慢大多是由于国内网络原因，所以没条件的使用镜像源。

中科大镜像(此为sh内容，直接执行请自行过滤不必要代码)

#!/bin/bash

# 替换brew.git:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

# 替换homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

# 替换homebrew-cask.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

# 应用生效
brew update
# 替换homebrew-bottles:
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

镜像源还原(此为sh内容，直接执行请自行过滤不必要代码)

#!/bin/bash

# 替换brew.git:
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

# 替换homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git

# 替换homebrew-cask.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask"
git remote set-url origin https://github.com/Homebrew/homebrew-cask.git

# 应用生效
brew update
# 后续需要删除环境变量：HOMEBREW_BOTTLE_DOMAIN，并刷新即可。

清华大学开源软件镜像站

更换成清华大学镜像源

cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.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

cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

brew update

临时替换

export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles

永久替换

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

更换成阿里云镜像源(还原同上)

# 替换brew.git:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
# 替换homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
# 应用生效
brew update
# 替换homebrew-bottles:
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile
# source ~/.zshrc

完成后就可以愉快的使用了

brew install mysql
mysql.server start
