Mac入门--通过homebrew下载过慢问题

使用国内的镜像替换homebrew镜像，对镜像进行加速源
原先我们执行brew命令安装的时候，跟3个仓库地址有关
1 brew.git
2 homebrew-core.git
3 homebrew-bottles
把三个仓库地址全部替换成国内Alibaba提供的地址

mac下安装和使用brew
一，安装brew
1，安装brew
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local –strip 1
2，安装完成后执行
brew
提示：Please run brew update!
3，按照提示更新，执行
brew update
报错：Error: /usr/local must be writable!
4，赋给/usr/local目录权限，执行sudo chown -R $(whoami) /usr/local，即
sudo chown -R fxp /usr/local
其中fxp为系统当前用户名。
5，再次执行
brew update
提示：
remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
HEAD is now at c3f959d Merge pull request #1542 from woodruffw/deprecate-utils-json
To restore the stashed changes to /usr/local run:
‘cd /usr/local && Git stash pop’

Error: Could not link:

Please delete these paths and run brew update.
==> Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew!
Homebrew no longer needs to have ownership of /usr/local. If you wish you can
return /usr/local to its default ownership with:
sudo chown root:wheel /usr/local
6，按照提示删除/usr/local/share/doc/homebrew，执行
rm -r -f /usr/local/share/doc/homebrew
7，再次执行
brew update
安装更新成功！
二，使用brew
命令行下执行brew，用法提示如下：
Example usage:
brew search [TEXT|/REGEX/]
brew (info|home|options) [FORMULA…]
brew install FORMULA…
brew update
brew upgrade [FORMULA…]
brew uninstall FORMULA…
brew list [FORMULA…]
Troubleshooting:
brew config
brew doctor
brew install -vd FORMULA
Developers:
brew create [URL [–no-fetch]]
brew edit [FORMULA…]
https://github.com/Homebrew/brew/blob/master/docs/Formula-Cookbook.md
Further help:
man brew
brew help [COMMAND]
brew home
常用命令有安装和卸载等，以安装和卸载autojump为例：
安装：sudo brew install autojump
卸载：sudo brew uninstall wget
查看安装软件的话，命令如下：
sudo brew search /apache*/
注意/apache*/是使用的正则表达式，用/分割。

前言：想学习一下Erlang,想通过homebrew安装一下环境，才发现新电脑还没有安装。通过官方命令在终端上安装时，发现小水管实在无法让人忍受。
于是只能通过国内镜像来安装啦，中间也遇到点问题下面把过程记录一下。
下面使用清华镜像
1.通过编辑install文件来使用镜像地
1.1获取brew_install
curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_instal
1.2编辑brew_instal
vim brew_instal
1.3在Vim模式下，按i，进入编辑模式，在BREW_REPO和CORE_TAP_REPO前加#注释掉，写入镜像地址代替
BREW_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git".freeze
CORE_TAP_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git".freeze
1.4按ESC退出编辑模式，输入:wq Return保存退出
2安装
2.1安装,运行install
/usr/bin/ruby ~/brew_install
2.2 出现如下代码时，不用等了，直接关掉命令窗口
==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...
2.3进入下面的 Taps 目录，clone homebrew-core
cd /usr/local/Homebrew/Library/Taps/homebrew
git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
3把homebrew repo切换为清华镜像
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
brew update
4 这时，终端会显示Already up-to-date.到此，homebrew就安装完毕了，我可以去安装Erlang啦

~/.cocoapods/repos/master重装
第一步：sudo rm -fr ~/.cocoapods/repos/master
第二步：git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
第三步：pod repo update
