1. Create http-server.go, where we will create a simple HTTP server that will render Hello World! browsing http://ec2-instance-public-dns:80 or executing curl -X GET http://ec2-instance-public-dns:80 from the command line, as follows:

package main
import 
(
  "fmt"
  "log"
  "net/http"
)
const 
(
  CONN_PORT = "80"
)
func helloWorld(w http.ResponseWriter, r *http.Request) 
{
  fmt.Fprintf(w, "Hello World!")
}
func main() 
{ 
  http.HandleFunc("/", helloWorld)
  err := http.ListenAndServe(":"+CONN_PORT, nil)
  if err != nil 
  {
    log.Fatal("error starting http server : ", err)
    return
  }
}

With everything in place, the directory structure should look like the following:

2. Copy http-server.go from the local machine directory to an EC2 user home (/home/ec2-user) directory using the secure copy or scp command, as follows:

$ scp -i my-first-ec2-instance.pem http-server.go ec2-user@ec2-172-31-34-99.compute-1.amazonaws.com:/home/ec2-user

3. Login into an EC2 instance using a private key file and a public DNS name, as follows:

$ ssh -i my-first-ec2-instance.pem ec2-user@ec2-172-31-34-99.compute-1.amazonaws.com

4. Run http-server.go in the background, executing the no hang-up or nohup command, as follows:

[ec2-user@ip-172-31-34-99 ~] $ nohup go run http-server.go &
