PHPMYADMIN Root reset

The latest version of PHPMYADMIN won’t allow root to login without a password, and you can only login to the phpmyadmin user.

Here’s how you work around it.

 

 

 

 

sudo mysql -u root

 

CREATE USER 'set-new-user'@'localhost' IDENTIFIED BY 'set-your-password';

GRANT ALL PRIVILEGES ON *.* TO 'your-suername'@'localhost';

FLUSH PRIVILEGES;

exit

sudo service service mysql restart

If that fails, try this:

 
sudo mysql -u root
use mysql;
update user set plugin='' where User='root';
flush privileges;
\q

Install TightVNC Server on the Asus Tinker board

I’m making this post for my own reference, though you can obviously use it as you wish.
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install xfonts-base
sudo apt-get install tightvncserver
sudo apt-get install nano

Run: vncserver
Add a password
My preferred command line option is vncserver -geometry 1280x720 (this sets the resolution to 720P)

I’m currently running Asus Linaro 1.8 debian based OS from a 120GB SSD and a using it as a Plex media server, for the most part it seems to work just fine, though some high bit rate 1080p movies struggle a little. I’m investigating further.

 

Installing a solid state drive or USB drive is as easy as the Raspberry Pi with just one slight difference. Plex Media server, HTOP, Webmin, Nextcloud and more are exactly the same, they just run a little better with the extra CPU power and extra 1GB of RAM.

Install Webmin on a Raspberry Pi

Webmin is a graphical user interface that can help you install, maintain and control your Raspberry Pi, all from a nice and simple GUI.

It’s also pretty easy to install and keep working, there are two methods to the install, I prefer the slightly longer but more thorough version, and that’s what I’ll be doing here.

  •  edit the sources list to add a new repository with:

sudo nano /etc/apt/sources.list

and add: deb http://download.webmin.com/download/repository sarge contrib

This has the benefit if updating Webmin in future when you type sudo apt-get update && sudo apt-get upgrade.

Type/Copy these line one at a time:

  • sudo su
    cd /root
    wget http://www.webmin.com/jcameron-key.asc
    apt-key add jcameron-key.asc

You’ve now added a security key to your Pi for the repo.

Same again, type/copy these lines one at a time.

 

  • apt-get update
    apt-get install apt-transport-https
    apt-get install webmin

BOOM! And about 10 minutes later you should be able to login via a web browser. Use the raspberry Pi IP address.

Example: https://192.168.1.20:10000 and you’re in 🙂

Use 1GB of Raspberry Pi RAM as a SWAP drive

If you have little use for the 2GB of RAM in a Raspberry Pi, then you could always use 1GB of it for a SWAP drive, this should improve performance for anyone running their Pi on a SD card.

If you want to use a SSD or USB Drive then checkout my easy as Pi tutorials here: https://the-bionic-cyclist.co.uk/category/raspberry-pi-tutorials/

As usual this is a quick and easy setup:
install ZRAM

sudo wget -O /usr/bin/zram.sh https://raw.githubusercontent.com/ric96/zram_rpi3/master/zram.sh

Make it executable.

sudo chmod +x /usr/bin/zram.sh

Edit this file to run on startup

sudo nano /etc/rc.local add line before exit 0 /usr/bin/zram.sh &

HTOP – Real time feedback from your Raspberry Pi

 

 

 

 

 

What is HTOP? Simply put, it’s a real-time feedback system to let you see what your Raspberry Pi is doing, what applications are running, and how much processing power is being used as well as where your RAM is being accessed and by what.

 

 

 

 

 

 

sudo apt-get install htop

It’s tiny and installs in seconds.

After that run htop by typing….

htop

 

Simples 🙂

Install Nextcloud cloud server on a Raspberry Pi

Nextcloud is a personal cloud server, you’re not relying on Apple cloud or Google or Dropbox to hold and secure (laughable) your data. If you have a Raspberry Pi at home you can host your own cloud server. There are desktop apps for Windows and Macs and apps for almost ALL mobile operating systems too.

The most popular self-hosted file share and collaboration platform

I’ve gone for the personal route because I find the free cloud server really don’t offer enough storage space, and security is a joke for most of them. Plus with the SSL guide you can make sure your is as secure as possible.

Setup SSL on a Raspberry Pi in 2 minutes

UPDATE: Lets Encypt have an auto install bot and it’s a signed certificate, meaning no warning! https://letsencrypt.org/

This is the LetsEncrypt Method:
sudo apt-get install certbot python-certbot-apache -t stretch-backports
sudo certbot --apache
sudo certbot --apache certonly
Test the automated update process.
sudo certbot renew --dry-run

Raspberry Pi Ad Blocker

I remember seeing something about an advert blocker for the raspberry pi but I can’t find the original post, so some googling later and I found pi-hole.
https://pi-hole.net/
It took less than a minute and it kicks Ad Blocker Pro’s arse then beats it while it’s down. It’s amazing, not one single damn advert gets through, and those that do you can add to a black list.

So if like me you’re sick to death of adverts and you don’t mind spending a few quid getting a raspberry pi then this is a must.

Once complete, change the DNS server of the client (PC, phone, laptop, tablet or just about anything that uses your internet connection) to your rasperry Pi’s IP address.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

curl -sSL https://install.pi-hole.net | bash

change the pi-hole password:

pihole -a -p newpasswordhere

 

 

Run a Raspberry Pi on a SSD or a USB Drive of any kind.

Well… technically it won’t boot from a hard drive, it has to be the boot partition on the SD card, but that’s actually just a small script setting up the root partition of the SD card.

The raspberry Pi is brilliant and every iteration has made it better and faster, all except one thing, the SD card. It still requires an SD card to boot up and run, but now you can run Linux from an SSD!

What I will show you is how to copy the contents of this root partition to an external drive, be it a USB memory stick, USB hard drive or like I have, an external USB Solid state drive.

This is actually a VERY VERY easy thing to do and aside from copying the contents from one drive to another, very quick too.

So the first thing to do is attach the USB drive to the Pi. For easy install I’ve already partitioned and formatted the drive to linux EXT4, all I need to do is discover where it is in the file system.
