Initial System Setup

• Raspberry Pi

• SD Memory Card Formatter Format SD card by using SD Memory Card Formatter

• Download NOOBS Download NOOBS and extract content of the zip to root of the SD card. Then insert the SD to Pi and powr on.

Post OS Install Basic Setup

User Management

Change passwd

passwd 
or 
passwd  <usr id>

Create a new user

sudo adduser <user id>

#Delete a user (the -r flag to remove their home folder too)
sudo userdel -r <user id>

Change the default edito from Nano to vim

visudo command uses the default editor Nano, to use vim then

sudo update-alternatives --set editor /usr/bin/vim.tiny

visudo edits the sudoers file, which is used by the sudo command

sudo visudo 
#or 
sudo vi /etc/sudoers

<user id>   ALL = NOPASSWD: ALL

Enable SSH

Vnc Setup

IBM No-charge products, tools, and toolkits

Update

sudo apt-get update
sudo apt-get upgrade
#sudo apt-get install git

nodejs

Remove old nodejs installation if any

sudo apt-get remove nodered -y
sudo apt-get remove nodejs -y
sudo apt-get remove nodejs-legacy -y
sudo apt-get remove npm  -y

If the node doesn’t get removed then you have to do a bit of manual work

# go to /etc/apt/sources.list.d and 
#remove any node list if you have; then do a
sudo apt-get update

# If you still see node, delete it from that location.
which node

Install 8x nodejs

# curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

FYI Only: Alternative approach

rm /work/nodejs
cd /work/dev

###### if ARM v7 (Raspberry Pi 3)
sudo wget https://nodejs.org/dist/v8.9.4/node-v8.9.4-linux-armv7l.tar.xz 
sudo tar -xvf node-v8.9.4-linux-armv7l.tar.xz
sudo ln -s  /work/dev/node-v8.9.4-linux-armv7l  /work/nodejs

export PATH=/work/nodejs/bin:$PATH
which node
node -v

Install the required build-tools

sudo apt-get update
sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

Build Python 2.7 from its source

cd /work/dev
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz

tar zxvf Python-2.7.13.tgz
ln -s  ./Python-2.7.13  ./Python

cd /work/dev/Python
sudo ./configure --enable-unicode=ucs4
sudo make
#  sudo altinstall

Build Python 3.x from its source

cd /work/dev
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
tar xf Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --enable-optimizations
make
# sudo make altinstall

Create a link for common usage

cd /work/dev
rm ./Python
# ln -s  ./Python-2.7.13  ./Python
ln -s  ./Python-3.6.2   ./Python
export PATH=/work/dev/Python:$PATH

Informix easy access path

sudo rm /work/informix
# sudo ln -s /work/dev/srv/sqldist.s /work/informix
sudo ln -s /work/dev/srv/sqldist.c /work/informix
