centos 7 安装golang1.13

方式一、用yum安装

yum install golang

方式二、使用二进制文件安装

wget https://dl.google.com/go/go1.13.5.linux-amd64.tar.gz

tar -zxf go1.13.5.linux-amd64.tar.gz -C /usr/local

vim /etc/profile

#golang env config
export GO111MODULE=on
export GOROOT=/usr/local/go
export GOPATH=/usr/local/go/gopath
export PATH=$PATH:$GOROOT/bin

cd /usr/local/gomkdir gopath

5、使换将变量配置生效，并查看golang的版本

source /etc/profilego version

go env -w GOPROXY=https://goproxy.cn,direct

cd /usr/local/go/gopathvim hello.go

package main  
import "fmt"  
func main() {  
    fmt.Printf("Hello, world!\n")  
}  

go run hello.go

Hello, world!
