ethopool

Open Source ETHO Protocol Mining Pool

Features

This pool is being further developed to provide an easy to use pool for Ethereum miners. This software is functional however an optimised release of the pool is expected soon. Testing and bug submissions are welcome!

• Support for HTTP and Stratum mining
• Detailed block stats with luck percentage and full reward
• Failover geth instances: geth high availability built in
• Modern beautiful Ember.js frontend
• Separate stats for workers: can highlight timed-out workers so miners can perform maintenance of rigs
• JSON-API for stats

Building on Linux

Dependencies:

• go >= 1.9
• geth or parity
• redis-server >= 2.8.0
• nodejs >= 4 LTS
• nginx

First of all let's get up to date and install the dependencies:

sudo apt-get update && sudo apt-get dist-upgrade -y
sudo apt-get install build-essential make git screen curl nginx tcl -y

Install GO:

wget https://storage.googleapis.com/golang/go1.16.15.linux-amd64.tar.gz
tar -xvf go1.16.15.linux-amd64.tar.gz
rm go1.16.15.linux-amd64.tar.gz
sudo mv go /usr/local
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

sudo nano ~/.profile

#add this in the end and save
export PATH=$PATH:/usr/local/go/bin

source ~/.profile
go version

Clone & compile:

git config --global http.https://gopkg.in.followRedirects true
git clone https://github.com/Exlo84/ethopool.git
cd ethopool
make

Installing Redis latest version

curl -O http://download.redis.io/redis-stable.tar.gz
tar xzvf redis-stable.tar.gz
cd redis-stable
make
make test 
sudo make install

sudo mkdir /etc/redis
sudo cp ~/redis-stable/redis.conf /etc/redis
sudo nano /etc/redis/redis.conf
    
# Set supervised to systemd
  supervised systemd
# Set the dir
  dir /var/lib/redis

**Create a Redis systemd Unit File

sudo nano /etc/systemd/system/redis.service

Add

[Unit]
Description=Redis In-Memory Data Store
After=network.target

[Service]
User=redis
Group=redis
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/local/bin/redis-cli shutdown
Restart=always

[Install]
WantedBy=multi-user.target

**Create the Redis User, Group and Directories

sudo adduser --system --group --no-create-home redis
sudo mkdir /var/lib/redis
sudo chown redis:redis /var/lib/redis
sudo chmod 770 /var/lib/redis

Start and Test Redis

sudo systemctl start redis
sudo systemctl status redis

Install Node.js

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install nodejs -y

Install Geth

cd ~
wget https://github.com/Ether1Project/Ether1/releases/download/V2.1.0/geth
sudo mv geth /usr/local/bin/geth 

Make geth system service

sudo nano /etc/systemd/system/geth.service

Copy the following

[Unit]
Description=Geth for Pool
After=network-online.target

[Service]
ExecStart=/usr/local/bin/geth --rpc --allow-insecure-unlock --rpcaddr 127.0.0.1 --rpcport 8545 --syncmode "fast" --etherbase <your-address> --mine --extradata "<your-pool>"
User=<your-user-name>

[Install]
WantedBy=multi-user.target

Then run geth by the following commands

sudo systemctl enable geth
sudo systemctl start geth
sudo systemctl status geth

Run console

geth attach

Register pool account and open wallet for transaction. This process is always required, when the wallet node is restarted.

personal.newAccount()
personal.unlockAccount(eth.accounts[0],"password",40000000)

Set up pool

mv config.example.json config.json
nano config.json

Make pool system service

sudo nano /etc/systemd/system/pool.service

Copy the following

[Unit]
Description=Ethopool
After=geth.target

[Service]
ExecStart=/home/<name>/ethopool/build/bin/ethash-galaxypool /home/<name>/ethopool/config.json

[Install]
WantedBy=multi-user.target

Then run pool by the following commands

sudo systemctl enable pool
sudo systemctl start pool
sudo systemctl status pool

Building Frontend

cd www

Modify your configuration file

nano ~/ethopool/www/config/environment.js

Create frontend

cd ~/ethopool/www/

sudo npm install -g ember-cli@^2.18.2
sudo npm install -g bower
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
npm install
bower install
npm i intl-format-cache

./build.sh

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

Serving API using nginx

Edit this

sudo nano /etc/nginx/sites-available/default

Delete everything in the file and replace it with the text below. Be sure to change with your info

upstream api {
        server 127.0.0.1:8080;
}

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  root /home/<name>/ethopool/www/dist;
 
 index index.html index.htm index.nginx-debian.html;
 
server_name _;
 
location / {
        try_files $uri $uri/ =404;
        }
  
location /api {
        proxy_pass http://api;
        }
}

Save and close

Restart nginx

sudo service nginx restart

How To Secure the pool frontend with Let's Encrypt (https)

First, install the Certbot's Nginx package with apt-get

$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install python-certbot-nginx

And then open your nginx setting file, make sure the server name is configured!

$ sudo nano /etc/nginx/sites-available/default
. . .
server_name <your-pool-domain>;
. . .

Change the _ to your pool domain, and now you can obtain your auto-renewaled ssl certificate for free!

$ sudo certbot --nginx -d <your-pool-domain>

Now you can access your pool's frontend via https!

Notes

• Unlocking and payouts are sequential, 1st tx go, 2nd waiting for 1st to confirm and so on. You can disable that in code. Carefully read docs/PAYOUTS.md.
• Also, keep in mind that unlocking and payouts will halt in case of backend or node RPC errors. In that case check everything and restart.
• You must restart module if you see errors with the word suspended.
• Don't run payouts and unlocker modules as part of mining node. Create separate configs for both, launch independently and make sure you have a single instance of each module running.
• If poolFeeAddress is not specified all pool profit will remain on coinbase address. If it specified, make sure to periodically send some dust back required for payments.
