How to spread web go applications on ubuntu • linux & open source

Go, also known as Golang, is an open source programming language developed by Google. Go is designed for efficiency, ease of use, and scalability. Very popular for building web applications, microser services, and cloud -based applications. In this guide, we will discuss how to use a simple Go Web application on Ubuntu using Nginx as an inverted proxy and systemD to manage application services.

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:

Response to commands:

Go version Go1.23.3 Linux/AMD64

go version Go1.23.3 Linux/AMD64

Create a go application

Create a directory for the application project with a name Goweb:

mkdir ~/goweb && cd ~/goweb

mkdir ~/Goweb && CD ~/Goweb

Create Main.go submit:

Fill in the file 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 Compilation:

Make services

Create SystemD Service File:

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

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

File:

[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 Services:

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

Create Nginx Configuration Files:

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

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

File:

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 your browser and visit the address:

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