go环境的安装
在linux虚拟机中安装分两步
解压go包到/usr/local下
wget https://studygolang.com/dl/golang/go1.10.linux-amd64.tar.gz
cp go1.10.linux-amd64.tar.gz /usr/local
tar zxvf go1.10.linux-amd64.tar.gz
根据个人虚拟机目录不同，设置环境变量
export GOROOT=/path/to/go/
export PATH=$PATH:$GOROOT/bin/
export GOPATH=/home/user/project/go
windows下安装直接下载文件一路next就可以了，https://golang.google.cn/doc/install?download=go1.11.4.windows-amd64.msi，设置环境变量使得go.exe能被找到

go的第一个hello world程序，hello.go
// 包名为main就是可执行文件，包名不为main就是一个普通的包或者库，不能执行 package main // 导入需要的包 import( "fmt" ) // func main是程序入口 func main(){ fmt.Println("hello, world!") }
使用go run hello.go运行它，输出hello，world
调试工具delve的安装
