Setup Ethereum Mining Pool using open source ethereum pool

Setup Ethereum Mining Pool using open source ethereum pool

This a step by step guide on how to setup your own Ethereum Mining Pool. This guide is going over how to setup an ethereum pool using open source ethereum pool software. This is meant to setup a mining pool for a SINGLE CRYPTO CURRENCY. This is not a guide for a Multipool!!!!

If you want to see what it looks like before you set it all up, head to the http://myetherpool.org/ what to see more pool check this list

For this guide purpose we I will be using Ethereum Crypto Currency .

Requirements

 

Setup

At this point you should have your VPS started, putty up and running and your logged in as root.

 

Update Ubuntu

apt-get update
apt-get dist-upgrade

Setup SWAP

I am setting up a 4GB swap, which may be overkill but it’s the most common swap sized used in most guides so ill keep it at that.

 

dd if=/dev/zero of=/mnt/myswap.swap bs=1M count=4000
mkswap /mnt/myswap.swap
swapon /mnt/myswap.swap

 

Now let’s add it into fstab so it’ll activate at boot.

nano /etc/fstab

Add the following line at the end of the file.

/mnt/myswap.swap none swap sw 0 0

Ctrl+O to save, and Ctrl+X to exit the nano editor.

Now your swap is setup, you can modify the size in the future if you need more or less.

Install Required Packages

 

apt-get install git
apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev
apt-get install libboost-all-dev git npm nodejs nodejs-legacy libminiupnpc-dev redis-server
apt-get update
apt-get install libdb4.8-dev libdb4.8++-dev
apt-get install golang

 

Installing nginx

 

sudo apt-get update
sudo apt-get install nginx

Ethereum Daemon Setup (Wallet)

 

Now let’s setup the coin daemon, I will be using Ethereum.

We can install in 2 way her is guide ..

First>> Installing from PPA

sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

If you want to stay on the bleeding edge, install the ethereum-unstable package instead.

After installing, run geth account new to create an account on your node.

You should now be able to run geth and connect to the network.

Make sure to check the different options and commands with geth --help

You can alternatively install only the geth CLI with apt-get install geth if you don’t want to install the other utilities (bootnode, evm, disasm, rlpdump, ethtest).

Second>> Building from source

Clone the repository to a directory of your choosing:

git clone https://github.com/ethereum/go-ethereum

Install latest distribution of Golang (v1.7) if you don’t have it already:

Building geth requires Go and C compilers to be installed:

sudo apt-get install -y build-essential golang

Finally, build the geth program using the following command.

cd go-ethereum
make geth

You can now run build/bin/geth to start your node.

Mining Pool Setup

 

Clone & compile:

git config --global http.https://gopkg.in.followRedirects true
git clone https://github.com/sammy007/open-ethereum-pool.git
cd open-ethereum-pool
make

Running Pool

 

./build/bin/open-ethereum-pool config.json

You can use Ubuntu upstart – check for sample config in upstart.conf.

Building Frontend

 

The frontend is a single-page Ember.js application that polls the pool API to render miner stats.

cd www

Change ApiUrl: '//example.net/' in www/config/environment.js to match your domain name. Also don’t forget to adjust other options.

npm install -g ember-cli@2.9.1
npm install -g bower
npm install
bower install
./build.sh

Configure nginx to serve API on /api subdirectory. Configure nginx to serve www/dist as static website.

Serving API using nginx

Create an upstream for API:

upstream api {
server 127.0.0.1:8080;
}

and add this setting after location /:

location /api {
proxy_pass http://api;
}

Customization

You can customize the layout using built-in web server with live reload:

ember server --port 8082 --environment development

Don’t use built-in web server in production.

Check out www/app/templates directory and edit these templates in order to customise the frontend.

Configuration

 

Configuration is actually simple, just read it twice and think twice before changing defaults.

Don’t copy config directly from this manual. Use the example config from the package, otherwise you will get errors on start because of JSON comments.

“threshold”: 500000000,
// Perform BGSAVE on Redis after successful payouts session
“bgsave”: false
}
}

If you are distributing your pool deployment to several servers or processes, create several configs and disable unneeded modules on each server. (Advanced users)

I recommend this deployment strategy:

  1. Mining instance – 1x (it depends, you can run one node for EU, one for US, one for Asia)
  2. Unlocker and payouts instance – 1x each (strict!)
  3. API instance – 1x

 

Congratulations You have now your own Mining Pool Ready to Start
