beego框架

https://beego.me/quickstart

$ go get -u github.com/astaxie/beego
$ go get -u github.com/beego/bee
export http_proxy="http://192.168.2.234:808/"

export https_proxy="https://192.168.2.234:808/"

yum install go

yum install golang

go version

go get -u github.com/astaxie/beego

go get -u github.com/beego/bee

echo 'export GOPATH="$HOME/go"' >> ~/.profile

echo 'export PATH="$GOPATH/bin:$PATH"' >> ~/.profile

exec $SHELL

source ~/.profile

export

go version

echo $PATH

echo $GOPATH

cd $GOPATH/src

bee new hello

cd hello

bee run

go env

在centOS下，安装go的环境，如下：
下载压缩包，wget https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz
解压该文件，由于默认的go路径，在/usr/local下， 所以用如下命令，解压创建/usr/local/go
tar -C /usr/local -xzf go1.8.1.linux-amd64.tar.gz 
配置环境变量，vim /etc/profile下，添加对应的goroot和gopath的配置环境
export GOROOT=/usr/local/go
export GOPATH=/app/gopath        之后，source /etc/profile 使得其配置文件有效.
检查go的版本，$ go version 
在go的开发路径下，我的demo是写在/app/gopath/src/hello下面的，编写helloworld.go的例子。  具体如下：
package main
import "fmt" 
func main() { 
    fmt.Printf("Hello, world.\n") 
} 
之后，go bulid helloworld.go，生成了helloworld的文件; 　或者直接执行 go run helloworld.go 直接可以看到结果
./helloworld 直接执行，输出了 Hello world
