mac OS簡單實用的包管理器Homebrew，真的非常好用

前言

今天安裝zookeeper時使用的是brew方式來安裝，才深深的體會到brew的厲害之處，閑話少叙，進入正題。

Homebrew的使用

1. 安裝Homebrew

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

在1中指令回車之後，會提示​

​Press RETURN to continue or any other key to abort​

​ (回車繼續或者按其他鍵終止)，這是直接回車進入“Downloading and installing Homebrew…”，

1. 如果網絡不好的話可能會提示“fatal: unable to access ‘https://github.com/Homebrew/brew/’: SSLRead() return error -9806…等”，沒關系重新輸入1的指令更新。
2. 用如下指令下載下傳安裝msf時，提示​

   ​curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused​

   ​ 解決辦法：

• 打開 https://www.ipaddress.com/ 輸入通路不了的域名，獲得對應的IP。
• 使用vim /etc/hosts指令打開不能通路的機器的hosts檔案，添加如下内容：

199.232.68.133 raw.githubusercontent.com
199.232.68.133 user-images.githubusercontent.com
199.232.68.133 avatars2.githubusercontent.com
199.232.68.133 avatars1.githubusercontent.com      

注：上面内容中199.232.68.133是raw.githubusercontent.com所在的伺服器IP（通過 https://www.ipaddress.com/ 獲知）。

儲存該檔案，再使用即可正常通路。

2. brew 常用指令（SoftwareName是你需要處理的軟體的軟體名）

1. 檢視軟體最新版本，​

   ​brew info SoftwareName​

   ​例如

brew info zookeeper      

1. 安裝軟體，​

   ​brew install SoftwareName​

   ​例如

brew install zookeeper      

1. 解除安裝軟體：​

   ​rew remove SoftwareName​

   ​例如

brew remove zookeeper      

1. 檢視通過brew安裝的所有軟體

brew list      

brew list 軟體名
