go开发环境搭建

官网 https://golang.google.cn/dl/

Linux环境：

cd /data/www 

wget https://golang.google.cn/dl/go1.14.7.linux-amd64.tar.gz

// 解压并安装到 /usr/local
tar -C /usr/local -xzf go1.14.7.linux-amd64.tar.gz

mkdir golang 

添加环境变量，开启go mod 包管理模式
vi /etc/profile

# go安装怒路
export GOROOT=/usr/local/go
# GOPATH环境变量
export GOPATH=/data/www/golang/path 
# 依赖包代理服务器
export GOPROXY=https://goproxy.io
# 开启go mod 模式
export GO111MODULE=on
export GOSUMDB=off

# go可执行程序导入到系统环境变量
export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:/data/www/golang/path/bin

source /etc/profile

go env 
go version 

mkdir -p project/demo1

cd project/demo1

vi hello.go

测试

package main

import "fmt"

func main(){
    fmt.Println("Hello World");
}

go run hello.go

补充：
1、go在1.13版本后，默认开启了GOSUMDB=sum.golang.org,而这个网址sum.golang.org 在国内是无法访问，报错如下
go get gopkg.in/ini.v1: gopkg.in/[email protected]: verifying module: gopkg.in/[email protected]: Get "https://sum.golang.org/lookup/gopkg.in/[email protected]": dial tcp 142.251.43.17:443: con nectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to r espond.

关闭方式：go env -w GOSUMDB=off

windows环境的配置

 vscode支持golang
1、Go 插件
2、安装gopls
3、当右下角出现Analysis Tools Missing的时候，点击一下，然后点击install即可。
