Creating DNS Records

purchased domain from Namecheap , and using Cloudfare as DNS server...need to add an A record in the DNS record management part in Cloudfare dashboard...

use @ for root
put the ip of your server in the IPv$ address section
disable proxy status (we're setup in our server later)
and set TTL (time to leave) as low as possible to avoid cache
finally click save

Query DNS Records with Dig

from your linux system run

dig softpipertesting.xyz A
dig +trace softpipertesting.xyz A

subdomain, CNAME, TEXT Records

doc link: https://wizardzines.com/zines/dns/ https://messwithdns.net/

SSH to your VPS with a domain name

 ssh root@softpipertesting.xyz

lsof -i :80

This will show the process ID (PID) of the service using port 80.

lsof -i :80

nc -l 80

listen to requests coming to port 80

nc -l 80

we can respond to the requests from netcat

HTTP/1.1 200 OK
Content-type: text/html

Install Caddy web server (alternative of Nginx)

doc link: https://caddyserver.com/docs/install#debian-ubuntu-raspbian

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

check if caddy is running

sudo service caddy status

add https

sudo nano /etc/caddy/Caddyfile

then replace :80 with domain name , say softpipertesting.xyz

restart the caddy service

service caddy restart

redirect ip to the root domain

213.210.21.240:80 {
        redir https://softpipertesting.xyz{uri}
}

add this to the /etc/caddy/Caddyfile file.

Multiple Caddyfile Setup

navigate to /ctc/caddy

then

mkdir sites-available 
mkdir sites-enabled
cp Caddyfile sites-available/Caddyfile
nano sites-available/Caddyfile

keep only , remove the rest

213.210.21.240:80 {
        redir https://softpipertesting.xyz{uri}
}

then

cd sites-available
mv Caddyfile http-redirects

file name is changed to http-redirects

navigate back to /etc/caddy

nano Caddyfile

modify the file to

softpipertesting.xyz {
        # Set this path to your site's directory.
        root * /usr/share/caddy

        # Enable the static file server.
        file_server

        # Another common task is to set up a reverse proxy:
        # reverse_proxy localhost:8080

        # Or serve a PHP site through php-fpm:
        # php_fastcgi localhost:9000
}

import sites-enabled/*

create a symbolic link for http-redirects file from sites-available to sites-enabled

ln -s /etc/caddy/sites-available/http-redirects /etc/caddy/sites-enabled/http-redirects

check if the link is created, from /etc/caddy/sites-enabled

ls -l

it will show , http-redirects -> /etc/caddy/sites-available/http-redirects

restart the caddy service

caddy service restart

redirect www subdomain to root domain

edit the http-redirects file in sites-available folder and add www.softpipertesting.xyz as space separated

213.210.21.240:80 www.softpipertesting.xyz {
        redir https://softpipertesting.xyz{uri}
}

setup /var/www folder

navigate to the var folder and

mkdir www
mkdir softpipertesting.xyz

time 37 min , see to folder security

create an index file ,

cd softpipertesting.xyz
nano index.html

navigate to the Caddy file in /etc/caddy and change the root

root * /var/www/softpipertesting.xyz

Transfer files to the server with scp

scp index.html root@softpipertesting.xyz:/var/www/softpipertesting.xyz

clone a git repository (public) to server

go to the directory and then clone the repository

git clone https://github.com/Al-ArafatSiddique/testing.git .

Hide files from Caddy File server

anyone can access https://softpipertesting.xyz/.git/HEAD we need to hide it... go to the Caddyfile...modify it

        # Set this path to your site's directory.
        root * /var/www/softpipertesting.xyz

        # Enable the static file server.
        file_server {
                hide .git
        }

handle errors in Caddyfile

softpipertesting.xyz {

        root * /var/www/softpipertesting.xyz

        # Enable the static file server.
        file_server {
