How to setup your witness for test net (Ubuntu 14.04)

The following instructions covers the setup of a witness in Ubuntu 14.04. The instructions are specific for the Test 2b release, but should be easily ported to other releases.

You can get latest version with chain id, genesis, and github tag here https://github.com/cryptonomex/graphene/releases

Note: Nodes might gone down as everyone is testing.

##Installation of dependencies Extracted from instructions here: https://github.com/cryptonomex/graphene/wiki/build-ubuntu, but limited only for witness / cli build.

If you already have done your installation move to next step

sudo apt-get update

Installation of development tools

sudo apt-get install gcc-4.9 g++-4.9 cmake make libbz2-dev libdb++-dev libdb-dev libssl-dev openssl libreadline-dev autoconf libtool git

If you cannot install gcc-4.9, you will need to add this repository before hand and try again.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

###Installation of BOOST

BOOST_ROOT=$HOME/opt/boost_1_57_0
sudo apt-get update
sudo apt-get install autotools-dev build-essential g++ libbz2-dev libicu-dev python-dev
wget -c 'http://sourceforge.net/projects/boost/files/boost/1.57.0/boost_1_57_0.tar.bz2/download' -O boost_1_57_0.tar.bz2
[ $( sha256sum boost_1_57_0.tar.bz2 | cut -d ' ' -f 1 ) == "910c8c022a33ccec7f088bd65d4f14b466588dda94ba2124e78b8c57db264967" ] || ( echo 'Corrupt download' ; exit 1 )
tar xjf boost_1_57_0.tar.bz2
cd boost_1_57_0/
./bootstrap.sh "--prefix=$BOOST_ROOT"
./b2 install [/code]

##Git checkout and build Ensure your boost path is correct

BOOST_ROOT=$HOME/opt/boost_1_57_0

Check out and build

cd ~
git clone https://github.com/cryptonomex/graphene.git
cd graphene

Check out test 2b (specific to this chain)

git checkout test2b

Update submodules and build make file

git submodule update --init --recursive
cmake -DBOOST_ROOT="$BOOST_ROOT" -DCMAKE_BUILD_TYPE=Debug .
make 

##Setup witness / import balances

Navigate to the witness directory

cd ~/graphene/programs/witness_node

Download genesis Path specific for Test 2b

 wget https://github.com/cryptonomex/graphene/releases/download/test2b/aug-31-testnet-genesis.json

Start a new terminal screen

 screen

Run the witness Current nodes for test 2b (replace for other tests)

./witness_node --rpc-endpoint "127.0.0.1:8090"  --genesis-json aug-31-testnet-genesis.json -d test_net_2b -s  "104.236.118.105:1776"

Note: -d parameter is for the directory you want the witness data to be stored -s is the node you want to connect

If you have problems, you might need to put the whole path for the genesis

./witness_node --rpc-endpoint "127.0.0.1:8090"  --genesis-json ~/graphene/programs/witness-node/genesis-json aug-31-testnet-genesis.json -d test_net_2b -s "104.236.118.105:1776" 

Detach from screen

 Ctrl A Ctrl D

Extract your wif keys for user and balances as per xeroc's instructions

Navigate to cli_wallet

cd ~/graphene/programs/cli_wallet

Run cli
Current chain id for test 2b

 ./cli_wallet -w test_wallet  --chain-id ecbde738ba0b319cb4d266e613b200d010da8b37313c20aec03f9c8e2d9b35e3

Note: -w is your directory wallet

Setup witness as per xerocs instructions

Howto-become-an-active-witness-in-BitShares-2.0

Remember to copy your keys, witness id Note you need to wait for a maintenance period to be voted in

Exit

Go back to your witness screen

screen -r

Exit your witness

ctrl c

Restart with parameters to start block producing (block producing needs your witness id and private keys) Current nodes for test 2b (replace for other tests)

./witness_node --rpc-endpoint "127.0.0.1:8090"  --genesis-json aug-31-testnet-genesis.json -d test_net_2b -s  "104.236.118.105:1776"  --witness-id '"1.6.5156"' --private-key '["GPH6JhL..your.signing.key..bc5mWyCvERV3coy","5K..your.secret..a"]'

See your witness producing blocks and you can Ctrl A Ctrl D to detach from screen.

##Tips

If you end up in a fork, or your blockchain gets corrupted it takes a long time to replay blockchain.

When I am synced, I shutdown with C-c (it should shutdown in a clean way) and I copy the blockchain folder as backup (if it shutdown without errors). Everytime my blockchain is corrupted, I remove the blockchain folder and I copy with the backup one and restart the witness. Finally I backup the blockchain folder every day.
