2. Configure Raspbian

All commands should be executed from the /home/pi folder, unless the guide says otherwise. Be aware linux is case-sensitive, make sure every command is typed accurately, one wrong character will make things not work properly or at all ! 1

To see the current folder you are in, type pwd

To return to /home/pi from any other folder, type cd and press enter

Whenever you are in the home folder the prompt will appear as [email protected]:~$

Change your password

When logged in as the pi user, you should change the default password as security measure to prevent anyone you don't want accessing the device. Changing your password is simple with this instruction following my example:

[email protected]:~$ passwd
Changing password for pi.
(current) UNIX password:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
[email protected]:~$

**Note: Characters will not be visible when typing passwords, be sure you enter them correctly ! Otherwise you'll lock yourself out of the pi

Change Password from Raspi-config menu on Jessie Pixel

Update Raspberry Pi System (This is critical!) :

Do: sudo apt-get update; sudo apt-get upgrade -y in order to update Raspbian's system before proceeding. This will take a while (20-30 minutes). Make sure to reboot after the updates!

Set locale

You need to set the locale (Language/Region settings) of Raspbian in order to run the Stratis.

Step 1) Reconfigure language/region settings

[email protected]:~$ sudo dpkg-reconfigure locales

Choose your desired language from the list by pressing spacebar ( en_US.UTF-8 is the preferred choice), then choose ok. On the second dialogue select none

Step 2) Update System-Wide Envrionment Language

Next you will need to set the system environment locale which affects all users, by doing the following at the prompt (change accordingly to suit your language choice from the previous step:

[email protected]:~$ sudo sh -c "echo 'LC_ALL=en_US.UTF-8\nLANG=en_US.UTF-8' >> /etc/environment"

Confirm the setting with:

[email protected]:~$ cat /etc/environment

Update the locale:

sudo update-locale

Now restart: sudo reboot

Connect to the network

Ethernet

Just connect your Raspberry Pi directly (Lan cable) to your router and you should be good to go.

You can verify if it has successfully connected typing at prompt: ifconfig eth0. If the inet addr field shows your network ip, the Pi has connected to the network. If not, try rebooting by typing sudo reboot.

Wifi

You need a Raspberry Pi 3 for this step. Older models does not have built in wifi.

It is recommended to use an ethernet cable while staking, but wireless should also work fine. You can skip this step if you use an ethernet cable.

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="wireless_network_name"
    psk="wireless_network_password"
}

When connecting to a network called "my_wifi" with password "qwerty", you would enter:

network={
    ssid="my_wifi"
    psk="qwerty"
}

Now save the file by pressing Ctrl+X then Y, and press Enter.

Reboot your Raspberry Pi with sudo reboot.

You can verify if it has successfully connected using ifconfig wlan0. If the inet addr field has an address beside it, the Pi has connected to the network. If not, check that your password and network name are correct. Also check that the syntax in the configuration file exactly matches the syntax above.

Check Your Network Connection is Online

Run ping -c 5 google.com. The result should look something like this:

5 packets transmitted, 5 received, 0% packet loss, time 4006ms
rtt min/avg/max/mdev = 1.346/1.438/1.697/0.130 ms

If it doesn't say 5 packets transmitted, 5 received, make sure you have connected the ethernet cable or have connected to wifi (see previous chapter).

**Note: There's known issue with Raspberry pi tending to drop its Wifi Connection, follow this guide as a remedy to make sure you're always connected to the network.
