Bitcoin full-node on Raspberry Pi with NFS storage

Submitted by gerry on Mon, 10/23/2017 - 11:55

I recently augmented my home-server with a bunch of additional storage. Since I have all this space, and a few Raspberry Pis lying around gathering dust, I though I might try running a Bitcoin Full Node at home. This has a couple of positive effects... it strengthens the overall bitcoin network, and it gives me a trusted verification for any inbound transactions.

I first created an NFS share on my home server... I allocated a 250GB LVM volume with an EXT4 filesystem to it, added it to /etc/exports and restarted nfs service. It was necessary to ensure that the user that owned the NFS share on the server had the same UID as the owner on the Pi. In this case, 101 for both.

I then installed the minimal Rasbian image onto a surplus 8GB MicroSD card and booted it up. I then followed these steps to install and build the bitcoin client...

1. Install prerequisites

sudo apt install build-essential autoconf libssl-dev libboost-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev libtool libevent-dev
 

2. Get bitcoin source (I got v0.15 which was the most recent 'stable', I would recommend getting whatever the most recent numbered release is)

git clone -b 0.15 https://github.com/bitcoin/bitcoin.git
 

3. Build - the 'make' will take some time

cd bitcoin/
./autogen.sh 
./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib" --disable-wallet
make
sudo make install

 

4. Enable ssh (this is specific to newer Rasbian releases)

sudo touch /boot/ssh
 

5. Add NFS share to fstab - in my case, my server is called 'erdos' and the share is located at /exports/blockchain... yours will differ

$ sudo vi /etc/fstab

Paste the following - yours may vary

erdos:/exports/blockchain   /home/pi/.bitcoin   nfs   defaults  0 0

Mount the filesystem...

$ sudo mount -a
 

6. Create systemd service file

$ sudo vi /etc/systemd/system/bitcoind.service

Paste the following - again, yours may vary

[Unit]
Description=Bitcoin daemon serivce
After=network.target

[Service]
Type=simple
User=pi
ExecStart=/usr/local/bin/bitcoind

[Install]
WantedBy=multi-user.target

 

7. Start and enable bitcoind service

[email protected]:~/bitcoin $ sudo systemctl start bitcoind
[email protected]:~/bitcoin $ sudo systemctl status bitcoind
● bitcoind.service - Bitcoin daemon serivce
   Loaded: loaded (/etc/systemd/system/bitcoind.service; disabled; vendor preset: enabled)
   Active: active (running) since Mon 2017-10-23 12:07:50 IST; 5s ago
 Main PID: 8717 (bitcoind)
   CGroup: /system.slice/bitcoind.service
           └─8717 /usr/local/bin/bitcoind

[email protected]:~/bitcoin $ sudo systemctl enable bitcoind
Created symlink /etc/systemd/system/multi-user.target.wants/bitcoind.service → /etc/systemd/system/bitcoind.service.

 

8. Confirm listening status

[email protected]:~ $ ss -ltp
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 127.0.0.1:8332 *:* users:(("bitcoind",pid=8717,fd=10))
LISTEN 0 128 *:8333 *:* users:(("bitcoind",pid=8717,fd=127))
LISTEN 0 64 *:33171 *:*
LISTEN 0 128 *:ssh *:*
LISTEN 0 64 :::39493 :::*
LISTEN 0 128 ::1:8332 :::* users:(("bitcoind",pid=8717,fd=9))
LISTEN 0 128 :::8333 :::* users:(("bitcoind",pid=8717,fd=126))
LISTEN 0 128 :::ssh :::*


9. Forward port 8333 to your bitcoin node

This will be specific to your router. It is recommended that you either configure a static IP on your Pi, or configure static DHCP on your router, so the Pi will always have the same IP.

 

 

Notes on downloading the blockchain:

The limited RAM in the Raspberry Pi can cause issues when downloading the entire blockchain... it may hang or otherwise misbehave. To avoid this, I temporarily installed bitcoin core on my main server to do the download, but since discovered that it is available via Bittorrent from https://getbitcoinblockchain.com/

Once downloaded, move the downloaded files to wherever your NFS share is and it will appear in the .bitcoin home directory.
