Masternode tasks

This is fast simple enumeration of regular task with cryptocurrency. Any cryptomoney is similar, therefore I use one of them - genesisx.

• Prepare Ubuntu 16 for installing cryptomoney

# sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev
# sudo apt-get install libminiupnpc-dev
# 
# sudo add-apt-repository ppa:bitcoin/bitcoin
# sudo apt-get update
# sudo apt-get install libdb4.8-dev libdb4.8++-dev
# sudo apt-get install libminiupnpc-dev
# 
# sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev



• Read source code and prepare it

# mkdir genesisx && cd genesisx
# git clone https://github.com/genesis-x/genesis-x.git
# cd genesis-x
# 
# sudo -i
# cd /home/coinadmin/genesisx/genesis-x
# root@ubuntu-bit:/home/coinadmin/genesisx/genesis-x# chmod 777 -R *
# su coinadmin



• Compile source code

# ./autogen.sh
# ./configure
# make
# sudo make install

Finish must look as:

libtool: install: /usr/bin/install -c genesisxd /usr/local/bin/genesisxd
libtool: install: /usr/bin/install -c genesisx-cli /usr/local/bin/genesisx-cli
libtool: install: /usr/bin/install -c genesisx-tx /usr/local/bin/genesisx-tx
libtool: install: /usr/bin/install -c test/test_genesisx /usr/local/bin/test_genesisx

This means you have masternode engine in your computer.




• Prepare first config for sync database. This is config example, of course you need to set your own X,Y,Z. Log/pass for connection between daemon and cli usually arbitrary. And node from witch you will read blockchain of cource is changing time on time, get last for this coin from http://xgs.ccore.online/connections




# cat .genesisx/genesisx.conf
rpcuser=3mes5o7mww289lc7r6zkqekmsdfkjmnnv8xj3rwvdinbhfuuwqj664qs3u1lb7kh5
rpcpassword=qdhjlnq4h3q66wg9pv7o99ipxzasdaskfdhsdfgxo2c4opy3o7yrco38ckj2
rpcport=555XX
rpcconnect=127.0.0.1
rpcallowip=127.0.0.1
server=1
daemon=1
listen=1
discover=1
staking=0
logtimestamps=1
maxconnections=50
txindex=1
zapwallettxes=0
externalip=ZZZ.ZZZ.ZZZ.ZZZ
port=YYYY
addnode=192.168.0.221:5555
addnode=95.216.59.97:5555
addnode=173.249.17.41:5555
addnode=5.189.182.209:5555
addnode=80.254.127.139:5555
addnode=62.122.242.31:5555
addnode=62.171.152.94:5555



• Start daemon

# genesisxd -daemon
# watch genesisx-cli getinfo

If you see something like in screen below, you have win, but usually to rich this step need a lot of efforts.



Take a time while database syncing. Usually this need a hours. Check daemon activity by.

# top
# watch iostat -x (need install firtly as sudo apt install sysstat)
# iptraf-ng (need install firstly as sudo apt-get install iptraf-ng)



• Clone database. Ordinary task is setup up a lot of masternodes simultaneously. There are a lot of way to do this, but below I show way to many login in the same machine. Firstly need to stop daemon.

# genesisx-cli stop

Than need to create needed quantity of new user.

# sudo useradd -s /bin/bash -d /home/coin1/ -m -G sudo coin1
# sudo passwd coin1 

And than copy database to each user

# sudo cp -R /home/coinadmin/.genesisx /home/coin1/.genesisx
# sudo chown -R coin1:coin1 /home/coin1/

Than need to change each config - port and rpcport - in each config.

#nano .genesisx/genesisx.conf

Than start daemon for each use account.

# genesisxd -daemon
# watch genesisx-cli getinfo



• If you server administrator, in next step you will receive private key for each masternode. You need to add it usually to a lot of config. I write script below to add user key to each config.

#!/bin/bash
genesisx-cli stop
sed -i '/^port/ a masternode=1' .genesisx/genesisx.conf
sed -i "/^port/ a masternodeprivkey=$1" .genesisx/genesisx.conf
echo -n " $1 "
grep '^port' .genesisx/genesisx.conf
genesisxd -daemon

Usually I also copy this script to /usr/local/bin, but no matter. Create it, mark as executable and perform it.

# nano addkey
# chmod +x addkey
# ./addkey ZZZZZZZZZZ



• Sentinel. Below is a simplest coin, a lot of coin need more, for example sentinel. For example this is workflow for gobyte-sentinel.

# sudo apt-get update
# sudo apt-get -y install python-virtualenv
# git clone https://github.com/gobytecoin/sentinel.git && cd sentinel
# virtualenv ./venv
# ./venv/bin/pip install -r requirements.txt
# crontab -e
# * * * * * cd /home/YOURUSERNAME/sentinel && ./venv/bin/python bin/sentinel.py >/dev/null 2>&1
# nano sentinel.conf
# gobyte_conf=/home/YOUR HOME DIRECTORY/.gobytecore/gobyte.conf
