此次安装的go version 版本是1.14.6
1, 先去官网下载安装包
- 下载
>> wget https://studygolang.com/dl/golang/go1.14.6.linux-amd64.tar.gz
- 解压
>> sudo tar -C /usr/local/ -xzvf go1.14.6.linux-amd64.tar.gz
- 确认下版本
>> cd /usr/local/go
>> bin/go version
go version go1.14.6 linux/amd64
2, 配置环境变量
>> vim /etc/profile
...
export GOROOT=/usr/local/go
export GOPATH=/usr/local/gopath
export PATH=$PATH:$GOROOT/bin
- 配置生效
>> source /etc/profile
3, 环境变量设置好后，可以通过在命令行输入go env 命令来进行测试。
>> go env

4, 设置go modules配置
>> go env -w GO111MODULE=on
>> go env -w GOPROXY=https://goproxy.io,direct
- 校验下修改过后的配置
