曾经的旧版: https://www.skiy.net/201512023931.html

已将此项目独立出来了:
https://github.com/skiy/golang-install

如上所述,由于上一个版本的脚本更新GO最新版本时,每次都需要重新定义最新版本号.这样很不智能…
所以我就抽空花了点时间,学习了几个脚本和正则,终于重写了一个最新版本…

功能比之前更强大啦!

智能获取最新版本安装. 其它的功能跟原来的完全一致.

支持自定义版本。
支持 Linux / MacOS / FreeBSD 等系统。
支持 树莓派等ARM开发板.

注意: 此脚本需要在 root 下操作.

线上使用方式:

curl https://raw.githubusercontent.com/skiy/golang-install/master/install.sh | sh
或
wget -qO- https://raw.githubusercontent.com/skiy/golang-install/master/install.sh | sh

MY_DIY_GO_VERSION 为自定义的 golang 版本号，如：1.10.1
自定义版本方式:

curl -SL https://raw.githubusercontent.com/skiy/golang-install/master/install.sh | bash /dev/stdin MY_DIY_GO_VERSION
或
wget -qO- https://raw.githubusercontent.com/skiy/golang-install/master/install.sh | bash /dev/stdin MY_DIY_GO_VERSION

以下方式:

将最底部源代码保存为文件名为 go.install.sh 的文件.
执行,以下命令安装最新版本

sh go.install.sh

或者给此文件添加可执行权限,再进行操作.
只有添加可执行权限后,方可自定义版本.

# 添加可执行权限
chmod +x go.install.sh

# 安装最新版本
./go.install.sh

# 自定义版本
./go.install.sh 1.9.2

脚本如下:

#!/bin/bash
