Automatic installation script for Skyminers / Skycoin node
We wanted to make the process of setting up a fully operational Skycoin Miner as easy as possible for everyone. To do so we developed an installation script that will do the complex process with ease and fully automated.
We also included auto start scripts to keep your miners operational after a reboot or a shutdown. They are also automatically installed with the script. The installation script needs only to be executed on one board and it logins in to the other boards via SSH itself to install them, too.
This tutorial is for the Software part of your Skyminer. For the hardware assembly, please use the following tutorial from the offical Skycoin project: https://downloads.skycoin.net/skywire/Skywire_Miner_Assembly_Manual_2_1.pdf

Depending on what OS you are using on your Workstation (the computer you use in your daily life), you need a special software (Etcher) to flash the image of the operation system for the Orange PI boards of your Skyminer to the SD Cards (shipped with your Skyminer).

All other tutorials we came across used the full desktop version (with GUI) of Armbian. We would highly recommend to only use the light/server version since a GUI setup always comes with a few downsides. First GUI needs more computing resources which can be used for the miner itself and second a desktop version comes with a lot of bloatware which increases the chances of a security breach. Our tutorial although is that simple and step by step that you will face no issues installing the server version.

PuTTY for Windows and Cyberduck for MacOS is used to remote control your Orange PI’s from your workstation. It makes it possible to copy & paste the commands given in this tutorial easily into the remote machine (the Orange PI’s). Putty is only necessary if you are working on a Windows and Cyberduck only for Mac workstations. All Linux workstation have an SSH client natively incorporated inside the terminal (if not it can be easily installed within the terminal). Later in this tutorial we will also explain how to connect to the Orange PI’s using both Putty and Linux SSH.

The download part is now finished! Let’s install the just downloaded software on your workstation (but not Armbian of course 😉). We think that process is straight forward, and you won’t need any further instructions for that. In case you do - feel free to contact us!
Alright! Now that your environment is perfectly prepared let’s get some stuff done. First, we start with flashing all 8 SD cards with Armbian using Etcher. Before we can do that, we need to unzip the Armbian download file. By doing the steps mentioned above we are going to make Armbian bootable on the Orange PI boards. If you are used to installing an operation system like Windows or Linux this step will come to some surprise for you. Etcher does basically the entire installation process without any user input. You just plug the SD cards into your Orange PI’s and as soon as you switch the power supply on the will boot into the ready to use OS right away. Ready? Let’s go 😊
-
Unzip the downloaded Armbian 7zip archive using 7zip. To do so right click on the archive, select 7-zip and then unzip to...
-
As a result, we get a new folder containing the file we going to need to flash the SD card with Etcher. It’s a .iso file.
-
Now open Etcher and click on “Select image”.
-
Select the Armbian .iso image (highlighed in yellow above) and click “Open”.
-
Insert the first microSD card into your computers SD Card reader. In most cases you will need an adaptor for that as shown below (SD or USB both work fine).
-
Now we need to select the drive of the microSD card. Sometimes the card gets selected automatically when it’s the only one connected to the PC. Attention! Be careful and select the right drive. If you accidently select a wrong drive you completely erase all its data. To prevent this rather unplug all other memory cards, USB sticks and external hard drives first (if possible).
-
Perfect now we are good to go. Press the “Flash!” button and lets flash 😊.
-
When you see the picture below the first card is successfully flashed. If something went south, please feel free to contact as for assistance.
-
Now repeat the same with the other 7 microSD cards.
-
Well done! Let’s take your awesome Skyminer and 4 of the 8 flashed microSD cards and insert the 4 cards to the top row of Orange PI’s.
You might think now why only 4 and only the top ones? Simple answer we need an HDMI display and a USB keyboard to prepare the operation system (Armbian) for the first start. The bottom raw is simply not accessible with an SD cable. So, we do the next steps on 4 cards and when finished we unplug them and plug them to the bottom row. After that we repeat the same steps with the last 4 microSD’s.
- Connect the Ethernet cables of your miner, internet router and your workstation. If you haven’t it done already, please connect your Skyminer’s router (WAN port) with your internet router using an ethernet cable. Also connect the Orange PI’s to the routers switch. Because of the hardware design of the Skyminer we need to make one adjustment before we continue. In order to be able to connect with the miner via SSH on a workstation we would need a 9th Ethernet port on the miner but there are only 8 available and those are used for the 8 Orange PI boards. To solve this we have 2 options:
- Use a comman network switch or hub and disconnect on Raspberry PI from the miners switch. Then plug in the ethernet cable from the workstation to the switch and also plug the ethernet from the disconnected Raspberry PI into the switch. After that plug another ethernet cable into the switch/hub and connect it with the miners switch.
- If you don't have a switch/hub at hand disconnect one Raspberry PI and continue with the following installation steps. We provide an additional script later in this tutorial to install the disconnected board after the installation of the other Raspberry PI's is finished. As soon as you have disconnected one board you can continue.
2. Okay now connect a HDMI display (if not available you can use a HDMI TV, too) and a USB keyboard to Raspberry PI number 1. There is no need for a mouse since wse decided to don’t use the GUI version of Armbian.
3. Turn on power for Raspberry PI number 1. Armbian is booting now and after a few seconds you should see a login screen like in the picture below. If something is not working here, please contact us for assistence.
4. Login as root with the password 1234. To do so enter “root” press enter and enter “1234” press enter. Linux usually don’t show anything while you type your password. That’s normal just type “1234” and press enter.
5. Now you are requiered to change the root password. Select a strong password here with at least 13 digits and one special character. (Use the same password for all other Raspberry PI’s)
6. Now we are asked to setup a user and give it a password. Since Armbian is based on Debian/Ubuntu the user can obtain sudo rights. That’s why we need to choose a strong password here, too. But again you can use the same for all 8 Raspberry PI’s. As username we have choosen “skyminer”, you can choose another one if you want.
7. Now you are asked a couple of questions about the new user. But you don’t need to provide them you can just hit enter and confirm with Y + enter at the end.
Full name: <Enter>
Room number: <Enter>
Work phone: <Enter>
Home phone: <Enter>
Other: <Enter>
Is the information correct: Y + <Enter>
8. Well done! We are logged in as root now. To make the board available for Putty/SSH and to use the webservices like the wallet we need to give it a static IP address. We do this in the next step…
9. In this last step (on the board it self) we give it an static IP. The router of the Skyminer always has the IP 192.168.178.1 which will also be both the satandard gateway as well as the DNS server for the Raspberry PI’s. We decided to give the boards the following IP addresses.
| Board Number | IP Address |
|---|---|
| Raspberry PI 1 | 192.168.178.101 |
| Raspberry PI 2 | 192.168.178.102 |
| Raspberry PI 3 | 192.168.178.103 |
| Raspberry PI 4 | 192.168.178.104 |
| Raspberry PI 5 | 192.168.178.105 |
| Raspberry PI 6 | 192.168.178.106 |
| Raspberry PI 7 | 192.168.178.107 |
| Raspberry PI 8 | 192.168.178.108 |
Now let us change the IP of the board according to the list above. For this example we use Raspberry PI 1.
In the terminal type and press enter afterwards:
nano /etc/network/interfaces
The network configuration file appears and we are about to make changes inside the green surrounded block (eth0):
Now lets modify the entries like the following:
# Wired adapter #1 stays as it is
allow-hotplug eth0 stays as it is
#no-auto-down eth0 insert # at the beginning
iface eth0 inet static delete dhcp and type static
address 192.168.178.101 remove # at the beginning and type IP from the table above (ex:192.168.178.101)
netmask 255.255.255.0 remove # at the beginning
gateway 192.168.178.1 remove # at the beginning
dns-nameservers 192.168.178.1 remove # and replace 8.8.8.8 8.8.4.4 with 192.168.178.1
Now your screen should look like this:
The changes must be saved to be put into effect. We do this by pressing Ctrl+x, then type Y and press enter. After that the window automatically closes. Now you are back in the terminal and we must reboot. To do so copy paste the following into your terminal:
sudo reboot now
The preconfiguration of the Raspberry PI 1 is finished at this point.
- Okay now repeat the same steps in this section (First Login to Armbian) on the other 3 plugged in microSD cards/Raspberry PI’s. When you are finished unplugged them and insert them into the bottom row of your Raspberry PI’s, plug in the left 4 microSD’s to the top row and do the same there. After that you are finished with this section.
In order to be able to connect to the terminal of your Raspberry PI’s remotly to easily maintain them from your workstation we need to setup Putty. If you using a Linux workstation theres is usally nothing to do since most Linux derivats come with an SSH incorporated in the terminal shell. Mac users gonna need Keka but for the purpose of this tutorial we will only show how to use Putty on Windows. If you have problems installing Keka on Mac or use the SSH client on Linux workstations feel free to contact us for further assistence. Let’s get started:
-
Open the Putty file you have downloaded at the beginning of this tutorial. In the window that opens type the IP address of the first Raspberry PI board into the red circled area and replace the three green “X” with the board you want to connect which would be according to list of IP’s above 192.168.178.101 for Raspberry PI 1 (the master board). After that click the “Open” button.
-
The following security alert is normal and can be easily ignored. Since you created the certificate yourself and we think you are trusting your self 😉. Just click on “Yes”.
-
You now have a remote terminal shell on your Raspberry PI and all commands you run will be run on the Raspberry PI not on your local machine.
-
You need to login to the Raspberry PI with your user and password. Type “root” when asked “Login as” and when you asked for the password type the one you have choosen when you first started the Raspberry PI. Be careful it’s the root password not the user password.
-
Congratulations now you can fully control the Raspberry PI from your workstation. We are finsihed here and you can move to the next step.
- Download the Install Script from our Github account. In the terminal type or copy paste the following command:
cd && wget https://raw.githubusercontent.com/dobby/SkyInstallScript/master/SkyInstallScriptStart.sh
Alright lets do some magic. Run the script! In the terminal shell type or copy paste the following command:
sh ~/SkyInstallScriptStart.sh
-
You will be asked for the root password you used for all boards. This is needed to automatically login to the Raspberry PI boards 2-8 and also install the software there automatically. Everyting is now done automatically you just need to wait a couple of minutes. You will be informed as soon the installation is finished.
-
CONGRATULATIONS!!! Your Skyminer is now fully installed!
