下载完成后,使用以下sha256sum命令验证tarball校验和
[root@VM_134_103_redhat go-study]# sha256sum go1.10.3.linux-amd64.tar.gz

使用该tar命令将tarball解压缩到/usr/local目录
[root@VM_134_103_redhat go-study]# sudo tar -C /usr/local -xzf go1.10.3.linux-amd64.tar.gz

现在我们需要通过调整PATH环境变量告诉我们的系统在哪里找到Go可执行文件二进制文件
[root@VM_134_103_redhat ~]# vi /etc/profile
加入到变量环境到最后
export PATH=$PATH:/usr/local/go/bin

[root@VM_134_103_redhat ~]# go version
go version go1.10.3 linux/amd64

运行
[root@VM_134_103_redhat go-study]# go run hello.go 
Hello, World!
[root@VM_134_103_redhat go-study]#

构建二进制

[root@VM_134_103_redhat go-study]# go build
[root@VM_134_103_redhat go-study]# ll

[root@VM_134_103_redhat go-study]# ./go-study 
Hello, World!
