Raspberry Pi 2 Model B Basic Configuration Part 1

10/6/2015

The Raspberry Pi is a credit-card sized general purpose Linux computer designed and manufactured by the Raspberry Pi Foundation, a non-profit organization dedicated to making computers and programming instruction as accessible as possible to the widest number of people. Just recently I installed at home to play with it. There are already lots of resources available from Internet. This post and others are used to record all steps I did for making it useful to my daily work.

1. Install Raspberry Pi Software

After you hooked up power cable, HDMI cable, mouse and keyboard, you will see the following screen:

Choose Raspbian [RECOMMENDED] then click Install on the right top corner. After around 25 minutes, OS will be installed successfully.

2. Run Raspberry Pi Software Configuration Tool

After you installed OS, the first time system will show you Raspberry Pi Software Configuration Tool to do some basic configuration such as change password, enable camera, etc.

Also you can run the Raspberry Pi Software Configuration Tool whenever you want by running the following command after you logged into device:

sudo raspi-config

During installation, the screen will notify you, by default, the user name is pi and password is raspberry.

2. Enable SSH

From Raspberry Pi Software Configuration Tools Setup Option 8 Advanced Options:

After enabled SSH, you should be able to use SecreCRT or Putty this kind of tool to access it remotely.

3. Enable Wireless

My package has a usb wireless card. Followed instruction below, I was able to enable it.

From SSH session, you can check your network configuration:

Adding your scanned wireless information to Raspberry Pi

Open the wpa-supplicant configuration file in nano:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Go to the bottom of the file and add the following:

network={
ssid="Bobby"
psk="password12345"
}

In a couple of seconds, your Pi will join into SSID you entered and got the ip address

pi@raspberrypi ~ $ ifconfig

4. Assign Static IP Address:

pi@raspberrypi ~ $sudo nano /etc/network/interfaces

auto lo

iface lo inet loopback
