Linux下搭建简易go环境

1.配置apt源

vim /etc/apt/sources.list
然后复制以下内容,当然为了保险起见可以先备份原文件

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

2.安装golang

sudo apt-get install golang

3.设置gopath ， 用于放置第三方lib库文件

1.临时修改：export GOPATH=/opt/go
2.直接修改 ~/.bashrc

echo export GOPATH=/opt/go >> ~/.bashrc 

3.编写第一个go程序

package main

import "fmt" 

func main() {
  fmt.Println("Hello world!")
}

4.运行go build

go build main.go 
./main
