centos7.8 安装golang（完整版）

1.下载

https://golang.google.cn/dl/

2.验证文件完整性

3.解压到/data1/usr/local/目录，并软链到/usr/local/go 

(注：阿里云ECS系统盘空间不够，故用此法)

4.配置环境变量

cat <<EOT  >> /etc/profile

export GOROOT=/usr/local/go

export GOPATH=/data1/workspace/go/go_path

export GOBIN=$GOPATH/bin

export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

EOT

或者：

echo -e "export GOROOT=/usr/local/go\nexport GOPATH=/data1/workspace/go/go_path\nexport GOBIN=$GOPATH/bin\nexport PATH=$PATH:$GOROOT/bin:$GOPATH/bin" >> /etc/profile

5.验证
