Linux下一键安装Go语言最新版本环境的教程

有点 Shell 基础，而且经常安装 Golang 的环境，为了方便自己，就写了个一键安装 golang 的环境教程，之前写过一次，但是不够智能，现在添加了几个功能。

1、可以自定义 Golang 版本号；
2、自动判断系统的相关信息(如32位or64位系统)及下载对应的地址

MY_DIY_GO_VERSION 为自定义的 golang 版本号，如：1.6.2

###第一种方式： 直接通过我写好的脚本一键安装(一键安装)。

截止发文时，Go 版本号为：1.7rc3   
### Ubuntu/CentOS:    

> 脚本默认版本号     
Wget方式：wget -qO- https://down.zzzzy.com/shell.install.go | sh     
Curl方式：curl -SL https://down.zzzzy.com/shell.install.go | sh  

> 自定义版本号      
Wget方式：wget -qO- https://down.zzzzy.com/shell.install.go | bash /dev/stdin MY_DIY_GO_VERSION    
Curl方式：curl -SL https://down.zzzzy.com/shell.install.go | bash /dev/stdin MY_DIY_GO_VERSION

https://down.zzzzy.com/shell.install.go?abc

###第二种方式：
将下面的代码复制到Linux服务器下任意一个目录，并将文件名改成 "xxx.sh"，再执行 sh xxx.sh MY_DIY_GO_VERSION
