beego框架
https://beego.me/ https://beego.me/quickstart
$ go get -u github.com/astaxie/beego $ go get -u github.com/beego/beeexport 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 $GOPATH/src
bee new hello
cd hello
bee rungo env
在centOS下，安装go的环境，如下：
下载压缩包，wget https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz
解压该文件，由于默认的go路径，在/usr/local下， 所以用如下命令，解压创建/usr/local/go
tar -C /usr/local -xzf go1.8.1.linux-amd64.tar.gz
配置环境变量，vim /etc/profile下，添加对应的goroot和gopath的配置环境
export GOROOT=/usr/local/go
export GOPATH=/app/gopath 之后，source /etc/profile 使得其配置文件有效.
检查go的版本，$ 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
