访问：[https://golang.org/dl/][https_golang.org_dl]

下载 [go1.12.4.linux-amd64.tar.gz][]

wget https://dl.google.com/go/go1.12.4.linux-amd64.tar.gz
    
    sudo tar -zxvf go1.12.4.linux-amd64.tar.gz -C /opt

检查安装是否成功

cd /opt/go/bin ./go version go version go1.12.4 linux/amd64

设置环境变量

vi /etc/profile
    
    export GOROOT=/opt/go export GOPATH=/home/ubuntu/go export GOPROXY=https://goproxy.io export GOARCH=amd64 export GOOS=linux export GOTOOLS=$GOROOT/pkg/tool export PATH=$PATH:$GOROOT/bin:$GOPATH/bin source /etc/profile

其中，GOPROXY 可以解决 golang.org/x/... 系列包无法下载的问题。

编写 HelloWorld 文件，测试运行环境。

package main import "fmt" func main(){ fmt.Println("hello,world!") }

go run hello.go
    go build hello.go

创建 go.mod 文件

go mod init hello

用 Gin 实现一个简单的 http 服务

import ( "gopkg.in/gin-gonic/gin.v1" "net/http" ) func main(){ router := gin.Default() router.GET("/", func(c *gin.Context) { c.String(http.StatusOK, "Hello World") }) router.Run(":8000") }

直接编译执行

go run hello

可以看到引用的包都被自动下载了

HTTP 服务启动正常，可以通过浏览器访问了。
