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
|
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
eth0 Link encap:Ethernet HWaddr b8:27:eb:1c:f4:ae UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback wlan0 Link encap:Ethernet HWaddr 74:da:38:41:33:35 |
4. Assign Static IP Address:
|
pi@raspberrypi ~ $sudo nano /etc/network/interfaces
auto lo iface lo inet loopback allow-hotplug wlan0 |
