INSTALL MONGODB ON RASPBERRY PI 4

By far the best guide I have found, in starting this journey, was written by Mark Smith on https://developer.mongodb.com/how-to/mongodb-on-raspberry-pi/

If you want to see why things work the way they do, please visit his guide. My guide below is just the commands, and how I am connecting into the database once it is setup.

To begin, first you will want to install Ubuntu Server 20.10 as described here:
https://tacticalware.com/install-ubuntu-server-20-10-64-bit-on-raspberry-pi-4-using-a-m-2-drive/

Once you are up and running, ssh into the Raspberry Pi
Login

From the terminal run the following:
sudo bash

wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –

echo “deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse” | tee /etc/apt/sources.list.d/mongodb-org-4.4.list

apt-get update

apt-get install -y mongodb-org

systemctl daemon-reload

systemctl enable mongod

systemctl start mongod

systemctl status mongod

CTRL button +c to exit

mongo
use admin

db.createUser( { user: "admin",
 
        pwd: "SuperSecretPassword",

        roles: [ "userAdminAnyDatabase",

                 "dbAdminAnyDatabase",

                 "readWriteAnyDatabase"] } )

exit

nano /etc/mongod.conf

Add these lines to the end of the file

security:

   authorization: enabled

CTRL +x to Exit
Y to Save

systemctl restart mongod

mongo

db.adminCommand({listDatabases: 1})

Make sure you had no errors

exit

mongo -u “admin” -p

Enter your admin password for mongo, aks your SuperSecretPassword

Type
db.adminCommand({listDatabases: 1})
This will list out your databases and ensure you created it properly

exit

nano /etc/mongod.conf
and Change the bind ip from 127.0.0.1 to 0.0.0.0

net:
   port: 27017
   bindIp: 0.0.0.0

CTRL +x to Exit
Y to Save

systemctl restart mongod

ufw allow 27017/tcp

MongoDB is now successfully setup and running. On to configuring the Windows 10 system

To connect to the MongoDB from a Windows 10 computer

Open an Internet Browser on your Windows 10 computer
Navigate to https://robomongo.org/
Download the Robomongo Robo 3T Client
Once you install it, add these settings to connect to your system
Click Create
Connection Tab
Type – Direct Connection
Address – The IP of your Raspberry Pi
Port 27017
Authentication Tab
Check mark Perform Authentication
Database is admin
User Name is admin
Password is your SuperSecretPassword
Auth is SCRAM
Click Save
Click Connect

You are now connected and ready to run with your MongoDB environment

INSTALL UBUNTU SERVER 20.10 64-Bit ON RASPBERRY PI 4 USING A M.2 Drive

This guide shows you how to install an Operating System on a Raspberry Pi 4. The one I chose for this guide is Ubuntu Server 20.10 64 bit, so if you are installing that, you can follow along easily. If you are wondering which hardware I used, the exact items are linked at the bottom

On a Windows computer
Insert your USB M.2 Drive into the USB 3.0 Port on your Windows computer
Open a web browser
Navigate to
Download the Raspberry Pi Imager

Once it is downloaded, double click the imager.exe file
Select Yes
Click Install
Checkmark Run Raspberry Pi Imager
Click Finish

Now that the Raspberry Pi Imager is running
Click Choose OS
Scroll down and select Ubuntu
Then select Ubuntu Server 20.10 (RPI 3/4/400) 64-BIT
Select your SD Card (500GB WD M.2 Drive)
Click Write
All existing data …. will be erased. Are you sure you want to continue?
Click Yes
Data is written to the SD Card
The data is automatically verified after it is written
Once it finishes you will see the message that “you can now remove the SD card from the reader”
Remove the card
Click Continue

Now back on the Raspberry Pi
Plug in network cable
Connect the keyboard
Plug in a mouse
Connect the HDMI cable
Install the M.2 USB Drive you just made (up above)
Plug in the power (Last step)

Boot up your Raspberry Pi
The first time you login the username is ubuntu
The password is ubuntu
You will be forced to change the password immediately
Now you will want to run the following commands
sudo bash
apt-get update
apt-get dist-upgrade
y
apt install net tools
ifconfig

Note your ip address

You can now connect remotely and finish setting up the system

You are done. Your Raspberry Pi 4 is setup with the Ubuntu Server 20.10

COMBINE MULTIPLE CSV FILES FROM THE COMMAND LINE AND RETAIN FILENAMES

For this guide we will take thousands of csv files and combine them into One single file, which will be uploaded to a database. This file will have a new column inserted, where the originating filename will be added next to the row. In scraping sites, often my output files are separated and after I clean them up I need to combine them. This is how I do it.

On my Windows 10 computer
I will copy my CSV files over to a secondary drive, leaving the originals intact.
Then I will open a command prompt as an administrator and navigate to that drive. If the files are on my H: drive will navigate by typing
H:
Then press Enter

Now I will navigate to the “dataset” folder
cd dataset

I will then list the directory contents to ensure this holds my csv files
dir

Once I see all of my csv files I will enter the following:

for /f %a in ('dir /b *.csv') do for /f "tokens=*" %b in (%a) do echo %b,%a >> combined-date.csv

Then press Enter

This will create a file called combined-04132021.csv (which is today’s date)

And I can then upload that file to my database easily

RASPBERRY PI 4 – FLIGHTAWARE SETUP

Flightaware…an amazing app, will give you a free subscription if you monitor the skies above your house. To setup a raspberry pi with this ability, perform the following

This guide assumes you have a Raspberry Pi, already setup with Raspbian. If you don’t have this, follow the guide below:
https://tacticalware.com/install-raspbian-os-on-raspberry-pi-4/

Once you are up and running with your Raspberry Pi, you will need to plug in your flightaware usb dongle which can be found on the bottom of this page

After that, run the following commands:
From your Raspberry Pi “Desktop”
Open a terminal
sudo bash
apt-get update
apt dist-upgrade
reboot

Your system will now reboot and come back up to your “Desktop”
Open a terminal
sudo bash
wget http://flightaware.com/adsb/piaware/files/packages/pool/piaware/p/piaware-support/piaware-repository_3.7.1_all.deb
dpkg -i piaware-repository_3.7.1.deb
apt-get update
apt-get install piaware
piaware-config allow-auto-updates yes
apt-get install dump1090-fa
reboot


Your system will now reboot and come back up to your “Desktop”
Open a terminal
sudo bash
ifconfig
get the ip address of your Pi
Open the Chromium web browser on your Raspberry Pi
Navigate to https://flightaware.com/adsb/piaware/claim
Create an account or Login and claim your piaware.
If successful you will see a message similar to the following message on the web page:
PiAware – Claim and Link a Brand New PiAware Ground Station
Success!
You claimed the following 1 receivers:
162323d5-6532-4s436-9486-d6173334

Next you will want to click on the link listed in your Success message:
Great news! Your account is associated with the following PiAware receivers and you can view your statistics here:
Now you will be in the config page of your flightaware account
So you will want to click on the Gear icon

ACCESSING .ONION SITES WITHOUT TOR

While TOR is the recommended way to access the dark web, everyone and anyone can still visit without the same level of anonymity. I certainly would suggest using TOR always, however if you need to get to any .onion site from a computer without tor, you can do so by following this:

Open an internet browser (Edge, Firefox, Chrome, etc)
Type in the .onion site (ex. https://protonirockerxow.onion/rc/)
After the .onion portion of the address, add .dog (ex
Press Enter
You are now viewing RISEUP’s website on the darkweb, using a regular browser
