到官方https://golang.org/dl/下载安装包

</pre><pre name="code" class="plain">#wget https://storage.googleapis.com/golang/go1.7.1.linux-amd64.tar.gz

# tar zxvf go1.7.1.linux-amd64.tar.gz -C /usr/local

新建GOPATH目录
# mkdir -p /mnt/wwwroot/gofile
# vim /etc/profile

export GOROOT=/usr/local/go
export GOBIN=$GOROOT/bin
export PATH=$PATH:$GOBIN
export GOPATH=/mnt/wwwroot/gofile
:wq保存

使其生效
#source /etc/profile

查看是否配置成功
# go version
go version go1.7.1 linux/amd64

简单测试：
# cd /mnt/wwwroot/gofile
# vim hello.go
package main
import "fmt"
func main() {
    fmt.Println("Hello, 世界")
}
# go run hello.go
Hello, 世界
