This guide assumes the following:
- You've downloaded Raspbian Lite ISO image.
- You've burn the image on the SDCard and you have some experiencethe working with the Raspberry Pi computer
- You've installed
Peercoin
on your computer and you want to transfer yourwallet.dat
file to your Raspberry Pi computer.
This guide has been confirmed working on:
- Pi 2 Model B v1.1 1GB a21041 (Embest, China) *
- Peercoin Daemon version v0.8.1.0
The following section was taken from this link.
-
Open up this file.
sudo nano /etc/hosts
-
Leave all of the entries alone except for the very last entry labeled 127.0.1.1 with the hostname
raspberrypi
. This is the only line you want to edit. Replace “raspberrypi” with whatever hostname you desire. I named my computerpeercoin-pi
. -
Back at the terminal, type the following command to open the hostname file:
sudo nano /etc/hostname
-
Replace the default “raspberrypi” with the same hostname you put in the previous step (e.g.
peercoin-pi
). -
Commit our changes.
sudo /etc/init.d/hostname.sh
-
Reboot the computer.
sudo reboot
-
Install firewall.
sudo apt-get install git ufw
-
Enable firewall and allow only ssh access
sudo ufw allow 22 sudo ufw allow 9901 sudo ufw --force enable sudo ufw status
-
To add more security, read this link.
The following section was inspired from this article. Please be warned that running the following code can shorten the life-span of your SDCard.
-
Configure using the following.
sudo dd if=/dev/zero of=/swapfile bs=64M count=16 sudo mkswap /swapfile sudo swapon /swapfile
-
(Optional) Stop our
swap
memory and remove it.sudo swapoff /swapfile sudo rm -f /swapfile
-
(Optional) Make the swap memory permanent on every boot.
sudo vi /etc/fstab
-
(Optional) Append the contents:
/swapfile none swap defaults 0 0
Please note these instructions where taken from this section. The following instructions are to be run on your raspberry pi.
-
Update the libraries.
sudo apt-get update
-
Install build requirements:
sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3
-
Install more requirements
sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev
-
(Optional) If above command doesn't work, you can install all boost development packages with:
sudo apt-get install libboost-all-dev
-
According to this link, we are compiling on
arm
processor so we need to run:sudo apt-get install g++-arm-linux-gnueabihf curl
-
Install
git
because it’s not installed.sudo apt-get install git
-
Clone Peercoin to our home directory.
cd /home/pi git clone https://github.com/ppcoin/ppcoin.git ``
-
To build our dependencies for
arm
, according to this link, then run the following:cd depends make HOST=arm-linux-gnueabihf NO_QT=1 cd .. ./configure --prefix=$PWD/depends/arm-linux-gnueabihf --enable-glibc-back-compat --enable-reduce-exports LDFLAGS=-static-libstdc++ make
-
To build our executable for
arm
, according to this link, then run the following:./autogen.sh ./configure make make install # optional
-
Upload the
wallet.dat
file on your computer to your raspberry pi.rsync -avz ~/Desktop/wallet.dat pi@192.168.1.10:/home/pi/.peercoin/wallets/wallet.dat
-
Run the following code to confirm the
Peercoin
daemon starts running in the background.cd /home/pi/ppcoin/src ./peercoind -listen=0 -daemon -server
-
If the daemon loads up then you have successfully built the executable.
This section had assistance from this link.
-
Install
screen
.sudo apt-get install screen
-
Open up our screen session.
screen bash
-
Start our session.
cd /home/pi/ppcoin/src ./peercoind -listen=0 -daemon -server
-
Detach the screen session so it runs in the background. Enter
CTRL
plusA
thenD
. -
Confirm our background process is running.
screen -list
-
(Optional) If you would like to resume your background session then run the following, else skip this step.
screen -r
-
Confirm our daemon is running in background by running the following command. (Don't forget to run
CTRL
plusX
when you finish)top | grep peercoin
-
(Optional) If you get any error, please investigate the
debug.log
file by running the following.~/.peercoin/debug.log
We are going to create a service in systemd
to have our peercoind
startup on boot time.
DEVELOPERS NOTE: For some reason the following code does not want to work. If someone can comment on how to fix this, that would be great!
-
While being logged in as
pi
run the following:cd ~/ touch peercoind_startup.sh vi peercoind_startup.sh
-
Populate the contents of our new file with the following
#!/bin/sh cd /home/pi/ppcoin/src ./peercoind -listen=0 -daemon -server
-
Give permission to run our script.
chmod u+x peercoind_startup.sh
-
Create our
systemd
service to handle loading our startup script.sudo vi /etc/systemd/system/peercoind.service
-
Copy and paste the following contents.
[Unit] Description=Peercoin Daemon After=multi-user.target [Service] Type=idle ExecStart=/home/pi/peercoind_startup.sh Restart=on-failure KillSignal=SIGTERM [Install] WantedBy=multi-user.target
-
We can now start the Gunicorn service we created and enable it so that it starts at boot:
sudo systemctl start peercoind sudo systemctl enable peercoind
-
Confirm our service is running.
sudo systemctl status peercoind.service
-
If the service is working correctly you should see something like this at the bottom:
raspberrypi systemd[1]: Started Peercoin Daemon.
-
Congradulations, you have setup instrumentation micro-service! All other micro-services can now poll the latest data from the soil-reader we have attached.
-
If you see any problems, run the following service to see what is wrong. More information can be found in this article.
sudo journalctl -u peercoind
-
To reload the latest modifications to systemctl file.
sudo systemctl daemon-reload
