mkdir -p ~/go_projects/{bin,src,pkg} 

4. cd/go_projects  
5.export  PATH=$PATH:/usr/local/go/bin
6. export GOPATH="$HOME/go_projects"
7. export GOBIN="$GOPATH/bin"
8.source ~/.profile
9.to checked using type go version:your output like: 
 go version go1.9.1 linux/amd64 
10.then go env : output is
  1. GOARCH="amd64"
    GOBIN="/root/go_projects/bin"
    GOEXE=""
    GOHOSTARCH="amd64"
    GOHOSTOS="linux"
    GOOS="linux"
    GOPATH="/root/go_projects"
    GORACE=""
    GOROOT="/usr/local/go"
    GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
    GCCGO="gccgo"
    CC="gcc"
    GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build215970517=/tmp/go-build -gno-record-gcc-switches"

 11.then create home named directory in src folder of go_projects like mkdir -p ~/go_projects/src/hello
 12.then Create and  run our first program :
  1. package main
    import "fmt"
    func main() {
    fmt.Printf("Hello,Gaurav Bole welcome in GoLang\n")
    }
