Go is an open-source and general-purpose programming language developed by Google. It is cross-platform, lightweight, and simple to build with, making it an ideal choice for software developers. It produces compiled machine code binaries so you don’t need source code compilation to create an executable file. Go language syntax is very similar to C language and offers a rich set of features such as structural typing, garbage collection, memory safety, and more.

Step 1 – Install Go Language

By default, the Go package is included in the Ubuntu default repository. You can install it using the following command.

apt install golang-go -y

Once the Go package is installed, you can verify its version with the following command:

go version


go version go1.18.1 linux/amd64

Step 2 – Create a Simple Go Application

In this section, we will create a Go application that will print “Hello Go Application” when accessing the domain.

First, create a project directory for your application.

mkdir project

Next, navigate to the project directory and initiate the project with the following command:

cd project
go mod init go.example.com/app

Next, create a Go application file.

nano main.go

Add the following code:

package main

import (

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello Go Application")

    http.HandleFunc("/greet/", func(w http.ResponseWriter, r *http.Request) {
        name:= r.URL.Path[len("/greet/"):]
            fmt.Fprintf(w, "Hello %s\n", name)

    http.ListenAndServe(":9990", nil)

Save and close the file, then compile the file into the executable binary file.

go build main.go

You can see the executable binary file using the following command:

ls -l


total 6152
-rw-r--r-- 1 root root      35 Oct 15 15:43 go.mod
-rwxr-xr-x 1 root root 6288896 Oct 15 15:44 main
-rw-r--r-- 1 root root     408 Oct 15 15:44 main.go

Step 3 – Create a Systemd Service File for Your Application

Next, you will need to create a systemd file to manage the Go application.

nano /lib/systemd/system/goweb.service

Add the following configurations:




Save and close the file, then reload the systemd daemon to apply the changes.

systemctl daemon-reload

Next, start and enable the Go service using the following command:

systemctl start goweb
systemctl enable goweb

You can check the status of the Go service with the following command:

systemctl status goweb


● goweb.service - goweb
     Loaded: loaded (/lib/systemd/system/goweb.service; disabled; vendor preset: enabled)
     Active: active (running) since Sun 2023-10-15 15:45:37 IST; 3s ago
   Main PID: 47830 (main)
      Tasks: 6 (limit: 9180)
     Memory: 1.1M
        CPU: 6ms
     CGroup: /system.slice/goweb.service
             └─47830 /root/project/main

Oct 15 15:45:37 ubuntupc systemd[1]: Started goweb.

Step 4 – Configure Nginx as a Reverse Proxy

Next, you will need to install and configure Nginx as a reverse proxy for the Go application. First, install the Nginx package with the following command:

apt install nginx

Next, create an Nginx virtual host configuration file.

nano /etc/nginx/conf.d/go.conf

Add the following configuration:

server {
    server_name go.example.com;
    location / {
        proxy_pass http://localhost:9990;

Save and close the file, then verify the Nginx for any syntax errors.

nginx -t


nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Then, restart the Nginx service to reload the changes.

systemctl restart nginx

Step 5 – Access Go Application

Now, open your web browser and access the Go application using the URL http://go.example.com. You will see the following screen.

access go web page

You can also greet with a specific keyword using the URL http://go.example.com:/greet/atlantic. You will see the following screen.

access Go greetings


In this post, we explained how to install Go and create a simple application on Ubuntu 22.04. We also configured the Nginx as a reverse proxy to access the application using the domain name. You can now deploy the Go application on dedicated server hosting from Atlantic.Net!
