1. install Go from here

wget https://dl.google.com/go/go1.10.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.10.linux-amd64.tar.gz

2. set up development folders

mkdir -p ~/go/src
mkdir -p ~/go/pkg
mkdir -p ~/go/bin

3. set up GOPATH & GOBIN

add the following lines to ~/.bashrc

export GOPATH=$HOME/go
export GOBIN=$HOME/go/bin
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

4. check Go version and Go environment

source ~/.bashrc
go version
go env

5. create hello.go

cd ~/go/src
vi hello.go 

package main

import "fmt"

func main() {
        fmt.Printf("Hello, world.\n")
}

6. run hello.go

go run hello.go # output: Hello, world.

7. build and install hello.go

go build hello.go   # create a new file hello on the same directory
./hello             # output: Hello, world.
hello               # -bash: /home/you/go/bin/hello: No such file or directory
go install hello.go # create a new file hello on ~/go/bin directory
hello               # output: Hello, world.
