How to Deploy Go Web App in Ubuntu • Linux & Open Source

The language of Go, also known as Golang, is an open-source programming language developed by Google. Go is designed for efficiency, ease of use, and scalability. Go language is very popular for building web applications, microservices, and cloud -based applications. In this guide, we will discuss how to get a simple web application on Ubuntu using Nginx as Reverse Proxy and SystemD to manage application service.

Install Go

Update and install Go:

Sudo Apt Update Wget Sudo tar -c/usr/local -xzf go1.23.3.linux -amd64.tar.gz echo ‘export path = $ path:/usr/local/go/bin’ >> ~/. Profile Source ~/. Profile

sudo appropriate renew

Wget https://go.dev/dl/go1.23.3.linux-amd64.tar.gz

sudo ter –C /Usr/local –XZF Go1.23.3.linux–AMD64.ter.GZ

echo ‘Path Export = $ path:/usr/local/go/bin’ >> ~/.profile

source ~/.profile

Verify the GO installation by displaying the version number:

The command response:

Go version Go1.23.3 Linux/AMD64

go version Go1.23.3 Linux/AMD64

Make a go app

Create a directory for application projects with names Goweb:

mkdir ~/goweb && cd ~/goweb

mkdir ~/Goweb && CD ~/Goweb

Create a file Main.go:

Submit Main.go:

The main import package (“fmt” “net/http”) Func Handler (w http.responsewriter, r *http.request) {fmt.fprintf (W, “Hello, World!”)} Func Main () {http.handlefunc (“/”/”,” Handler) {http.handlefunc (“/”/”,” handler) {http.handlefunc (“”/”,” handler) HTT.

packaging main

import (

“FMT”

“NET/HTTP”

)

Func Pawang(w http.Responsewriter, R *http.Request) {

FMT.Fprintf(w, “Hello, the world!”)

}

Func main() {

http.Handlefunc(“/”, Pawang)

http.Listenandserve(“: 8080”, zero)

}

Application Compile:

Make service

Creating a service system system:

SUDO NANO/ETC/SYSYSTEMD/SYSYSTEM/GOWEB.Service

sudo Nano /etc./SystemD/system/Goweb.serve

SUBMIT:

[Unit] Description = Go Web App After = Network.Target [Service] Execstart =/Home/Youurizer/Goweb/App Restart = Always User = Youurizer Group = Youurizer Environment = Port = 8080 [Install] WANTEDBY = MULTI-USER. TARGET

[Unit]

Information=Go Web Application

After=network.target

[Service]

Execstart=/House/Youurizer/Goweb/application

Restart=always

User=Youurizer

Group=Youurizer

Environment=HARBOR=8080

[Install]

Searching for=multi–user.target

Activate service:

Sudo SystemCTL Daemon-Reload Sudo Systemctl Activating Goweb Sudo SystemCtl Start Goweb Sudo SystemCtl Status Goweb

sudo SystemCTL Daemon–Re -load

sudo SystemCTL possible Goweb

sudo SystemCTL beginning Goweb

sudo SystemCTL status Goweb

Nginx configuration

Install Nginx:

sudo apt install nginx -y

sudo appropriate install Nginx –Y

Creating Nginx Configuration Files:

SUDO NANO/ETC/NGINX/CONF.D/GOWEB.CONF

sudo Nano /etc./Nginx/conf.D/Goweb.conf

SUBMIT:

server {listen 80; server_name yourdomain.com; location / {proxy_pass proxy_http_version 1.1; Proxy_Set_Header Upgrade $ http_upgrade; proxy_set_header connection ‘upgrade’; proxy_set_header host $ host; proxy_cache_bypass $ http_upgrade; }}

server {

listen 80;

server_name Your domain.com;

Location / {

Proxy_pass http:// localhost: 8080;

proxy_http_version 1.1;

proxy_set_header Increase $http_upgrade;

proxy_set_header Connection ‘increase’;

proxy_set_header Host $host;

Proxy_cache_Bypass $http_upgrade;

}

Restart nginx:

Sudo systemctl restart nginx

sudo SystemCTL Restart Nginx

Application test

Open the browser and visit the address:

The result is the text “Hello, World!”.

Good luck 🙂
