Setup Ethereum Mining Pool using open source ethereum pool



** Updated on 12/28/2018 with new Go version & new demon compilation process
This a step by step guide on how to setup your own Ethereum Mining Pool. This guide is going over how to setup an ethereumpool 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 16

sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot
Install make and build tools
sudo apt-get install build-essential make
GoLangInstall GoLang
wget https://storage.googleapis.com/golang/go1.9.2.linux-amd64.tar.gz
sudo tar -xvf go1.9.2.linux-amd64.tar.gz
sudo mv go /usr/local
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
export GOPATH=$HOME/go
Type: go version
You should have a response with the version.

Installing Redis latest version

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make
sudo cp src/redis-server /usr/local/bin/
sudo cp src/redis-cli /usr/local/bin/
sudo mkdir /etc/redis
sudo mkdir /var/redis
sudo cp utils/redis_init_script /etc/init.d/redis_6379
sudo cp redis.conf /etc/redis/6379.conf
sudo nano /etc/redis/6379.conf
  • Edit the configuration file, making sure to perform the following changes:
  • Set daemonize to yes (by default it is set to no).
  • Set the dir to /var/redis/6379 (very important step!)
sudo mkdir /var/redis/6379
sudo update-rc.d redis_6379 defaults
sudo /etc/init.d/redis_6379 start

Test Redis Install

redis-cli
Expected response
redis 127.0.0.1:6379> ping
PONG
exit

Install nginx

sudo apt-get install nginx
NGINX starts automatically on port 80. This is all that needs to be competed at this step.

NPM and NODE Install

Install using this guide provided ..
ln -s `which nodejs` /usr/bin/node

User Setup

You never run things like your coin daemon (wallet), or pool as root!
Let’s create a user for your mining pool.
Login to ssh using putty as root.
adduser usernameyouwant
You’ll be prompted for a password, please use a password that is different from your root password.
The other info it asks for you can either fill out or just leave blank and hit enter.

Ethereum Daemon Setup (Wallet)

Now let’s setup the coin daemon, I will be using Ethereum.
cd ~
mkdir eth
cd eth
git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
export GOPATH=$HOME/go
make all

Run Eth For first Time

cd build/bin/
./geth --fast --cache=512
It will start sync process depend on speed of of your server it may take time to completely sync .
Once complete now we need generate wallet address in our pool wallet
./geth –rpc console
-add account for miner pool
personal.newAccount()
You will see like this ” 0xf0d066c928aeb570847900a1a39fde27a98d83ce ”
Save this adders in you pc somewhere as we need to use this in later stage of configuration
DON’T FORGET PASSWORD
To Exit: Control B release buttons and then press D

Mining Pool Setup

cd ..
git clone https://github.com/sammy007/open-ethereum-pool.git
cd open-ethereum-pool
IF YOU NEED TO RUN MAKE AGAIN USE:
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
export GOPATH=$HOME/go
make
** Edit open-ethereum-pool >>payouts >>unlocker.go  and change  [ var homesteadReward = math.MustParseBig256(“3000000000000000000”) ] with your coin block reward
**  Edit pool configs before ./build
cp ~/open-ethereum-pool/config.example.json ~/open-ethereum-pool/build/bin/config.json
edit config.json
** edit www/config/environment.js
Change ApiUrl: ‘//example.net/’ to ApiUrl: ‘//youtdomain.com:8080/

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.

// 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
