Step1：下载&解压

下载地址：https://golang.google.cn/dl/
根据需要，选择对应的版本进行下载。本文使用go1.13.4.linux-amd64。

使用wget下载：

shell> wget https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz

验证下载文件的完整性：

shell> sha256sum go1.13.4.linux-amd64.tar.gz

解压：

shell> tar -zxvf go1.13.4.linux-amd64.tar.gz
...
go/test/typeswitch.go
go/test/typeswitch1.go
go/test/typeswitch2.go
go/test/typeswitch3.go

go/test/utf.go

Step2:配置GOPATH

修改profile：

shell> cp /etc/profile /etc/profile_bak_`date +%Y%m%d`
shell> echo "# config go path" >>  /etc/profile
shell> echo "export GOPATH=/data/sde/go/go" >>  /etc/profile
shell> echo "export export PATH=\$PATH:\$GOPATH/bin" >>  /etc/profile
shell> echo "" >>  /etc/profile

确认修改后的profile是否正确：

shell> cat /etc/profile
...
# config go path
export GOPATH=/data/sde/go/go
export export PATH=$PATH:$GOPATH/bin

让修改后的profile生效：

shell> source /etc/profile

Step3：验证

查看版本

shell> go version
go version go1.13.4 linux/amd64
