Install Dogecoin Core on a Raspberry Pi

This post will show how to install dogecoin core on a raspberry pi and running a testnet, and how to use the json-rpc to interact with the blockchain and your wallet node.

Environment

Set the environment variables:

$ export CRYPTO_NAME="dogecoin"
$ export VERSION="1.14.4"
$ export ARCH="arm"

Installation

Install Dogecoin:

$ sudo mkdir -p /blockchain/${CRYPTO_NAME}/{config,data,software}
$ sudo mkdir -p /blockchain/${CRYPTO_NAME}/software/${VERSION}/bin
$ sudo chown -R pi:pi /blockchain
$ cd /tmp
$ wget https://github.com/${CRYPTO_NAME}/${CRYPTO_NAME}/releases/download/v${VERSION}/${CRYPTO_NAME}-${VERSION}-${ARCH}-linux-gnueabihf.tar.gz
$ tar -xvf ${CRYPTO_NAME}-${VERSION}-${ARCH}-linux-gnueabihf.tar.gz -C /blockchain/${CRYPTO_NAME}/software/${VERSION}/bin --strip-components=1
$ ln -s /blockchain/${CRYPTO_NAME}/software/${VERSION} /blockchain/${CRYPTO_NAME}/software/current

Setup environment to persist across reboot, re-logon:

$ cat /etc/profile.d/dogecoin.sh
export PATH=$PATH:/blockchain/dogecoin/software/current/bin

Configuration

Configure dogecoin:

$ cat /blockchain/dogecoin/config/dogecoin.conf
datadir=/blockchain/dogecoin/data  
printtoconsole=1  
rpcallowip=127.0.0.1  
rpcuser=user  
rpcpassword=pass  
rpcclienttimeout=300  
testnet=1  
prune=1000  
[test]
rpcbind=127.0.0.1  
rpcport=44555

Setup SystemD unit file:

$ cat /etc/systemd/system/dogecoind.service
[Unit]
Description=Dogecoin(DOGE) Testnet  
After=network.target

[Service]
User=pi  
Group=pi  
WorkingDirectory=/blockchain/dogecoin/data  
Type=simple  
ExecStart=/blockchain/dogecoin/software/current/bin/dogecoind -conf=/blockchain/dogecoin/config/dogecoin.conf  
StandardOutput=syslog  
StandardError=syslog  
SyslogIdentifier=dogecoin

[Install]
WantedBy=multi-user.target

Enable and restart dogecoind:

$ sudo systemctl daemon-reload
$ sudo systemctl enable dogecoind
$ sudo systemctl restart dogecoind
$ sudo systemctl status dogecoind
