How to Build Terracoin on Ubuntu Linux

Yet another SHA256 crypto-currency based on Bitcoin. Terracoins are issued to enduser nodes that verify transactions through computing power; it is established that there will be a limited and scheduled release of no more than 42 million coins.

To build Terracoin on Ubuntu is very simple as long as you are using the correct version of the operating system.

Requirements

• Ubuntu Linux 10.04.3 LTS Server 32-bit or 64-bit
• About 2 Hours of time

I am installing Ubuntu Server on a VMWare virtual machine. If you are using a regular computer or some other type of vitalization software you may skip the VMWare Tools Installation section. The rest of these instructions assume you have a fresh clean installation of Ubuntu 10.04.3 LTS all ready.

Pre-Setup

Before we continue, lets apply any pending updates and reboot:

sudo -s
apt-get update
apt-get upgrade
reboot

If you are using VMWare, the following commands will install VMWare tools with minimal effort:

sudo -s
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
ls /mnt/cdrom
tar xzvf /mnt/cdrom/VMwareTools-9.0.0-782409.tar.gz -C /tmp/
cd /tmp/vmware-tools-distrib/
./vmware-install.pl -d
reboot

Install Dependencies

Installing all the required libraries and header files is as simple as just copying and pasting each line below into your console.

sudo -s
apt-get install build-essential
apt-get install libssl-dev
apt-get install libdb4.8-dev
apt-get install libdb4.8++-dev
apt-get install libboost-all-dev
apt-get install git-core
apt-get install ntp

We install NTPd to keep our system's time in sync. This is very important for crypto-currencies.

Download Source Code, Build, and Install

Now comes the exciting part. We download the Terracoin source from the GIT repository then build the binary. Just copy and paste each line below into your console.

cd /usr/local/
git clone https://github.com/terracoin/terracoin.git 
cd terracoin/
cd src/
nice make -f makefile.unix -j 4 USE_UPNP=

The build should take about 1 hour to complete depending on the speed of your system. When done, finish up the process by removing the debug symbols from the Terracoin binary. Lastly copy the binary to it's final install location:

strip terracoind
cp terracoind ..

Congratulations! Terracoin has been built and installed.

Final Steps

We need to install a configuration file and the startup scripts. Luckily for you this can be done with just a few more commands that you can copy and paste into your console:

wget -qO /etc/init.d/terracoin http://www.unibia.com/unibianet/sites/default/files/terracoin-init.txt 
wget -qO /etc/default/terracoin http://www.unibia.com/unibianet/sites/default/files/terracoin-default.txt 
wget -qO /etc/terracoin.conf http://www.unibia.com/unibianet/sites/default/files/terracoin-conf.txt 
mkdir -p -m 777 /var/db/terracoin
chmod +x /etc/init.d/terracoin

The configuration file needs to be adjusted to your needs. Mostly you need to setup a "rpcpassword". Edit the file /etc/terracoin.conf using your favorite editor. On Ubuntu 10.04.3LTS you can use "nano /etc/terracoin.conf".

rpcuser=admin
rpcpassword=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
rpcport=18332
rpcallowip=127.0.0.1
rpcallowip=192.168.0.*
maxconnections=300
addnode=63.247.147.163:28333
server=1
listen=1
daemon=1
logtimestamps=1

You should be able to start, stop, and check the status of the Terracoin service with these commands:

service terracoin stop
service terracoin start
service terracoin status
