Open Source Mining Pool

Building on Linux

Dependencies:

• 64 bit ubuntu
• NOTE: centos can also work, but some of the commands may be different for the packages
• go >= 1.10
• gcc-c++
• make
• redis-server >= 2.8.0
• nodejs >= 4 LTS
• nginx
• Pirl geth client
• recommended to have more then 2 GB of ram, or a swap file set, or compiling may fail.
• if you need to make swap, you can run this to add a 3 gig swap file (not usually on openvz vps, it will fail most likely)

if [ ! -e /swapfile ]
   then
   fallocate -l 3G /swapfile
   chmod 600 /swapfile
   mkswap /swapfile
   swapon /swapfile
   cp /etc/fstab /etc/fstab.bak
   echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
fi

note about conventions here, "$" means you are not root, "#" means you are root.

Update installed packages

$ sudo yum update
or
$ sudo apt-get update
$ sudo apt-get -y dist-upgrade

Install go lang

$ sudo apt-get install -y build-essential golang-1.10-go unzip git wget curl
$ sudo ln -s /usr/lib/go-1.10/bin/go /usr/local/bin/go
or
$ sudo yum install -y epel-release
$ sudo yum install -y golang unzip git wget curl
$ sudo ln -s /usr/lib/go-1.10/bin/go /usr/local/bin/go

Install redis-server

(easiest to use the packages from the OS vender)

$ sudo apt-get install -y redis-server
or
$ sudo yum install -y redis

It is recommended to bind your DB address on 127.0.0.1 or on internal ip. Also, please set up the password for advanced security!!!

Install nginx

$ sudo apt-get install nginx
or
$ sudo yum install nginx

sample config located at configs/nginx.default.example (HINT, edit and move to /etc/nginx/sites-available/default)

Install gcc-c++ and make

$ sudo apt-get -y install gcc make
or
$ sudo yum install gcc make

Install NODE

This will install the latest nodejs

$ curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash -
$ sudo apt-get install -y nodejs
or
$ curl -sL https://rpm.nodesource.com/setup_11.x | sudo -E bash -
$ sudo yum install -y nodejs

Install PIRL geth (with PIRL-GUARD) (regular binary, not the masternode binary)

download from https://git.pirl.io/community/pirl/tags/pirl-linux-amd64-hulk-1_8_2

$ wget https://git.pirl.io/community/pirl/uploads/64bbf8b91bff94167cfc428ad5066f5e/pirl-linux-amd64-1.8.27-damocles
$ chmod 0755 pirl-linux-amd64-1.8.27-damocles
$ sudo mv pirl-linux-amd64-hulk-1_8_2 /usr/local/bin/pirl-linux-amd64-1.8.27-damocles

$ optional: start the binary and sync the chain up.
$ /usr/local/bin/pirl-linux-amd64-1.8.27-damocles  (control c when it reaches a blocks=1 each block line)

Install Pool

$ git clone https://github.com/phatblinkie/official-pirl-testnet-pool.git
$ cd official-pirl-testnet-pool
$ make all
$ ls build/bin/

you should see the pool binary there.

install systemd service files

 these are located in configs/systemd_files/
 be sure to edit the ExecStart for your systems paths to the json configs, and the location of the built binary

Open Firewall

Firewall should be opened to operate this service. Whether Ubuntu firewall is basically opened or not, the firewall should be opened based on your situation. You can open firewall by opening port TCP:80,443,30303,8002,8004,8008 UDP:30303

Install Frontend

Modify configuration file

$ nano www/config/environment.js

Make some modifications in these settings.

APP: {
  // API host and port
  ApiUrl: '//testnetpool.pirl.io/',
  PoolName: 'PIRL TESTNET Pool',
  CompanyName: 'PIRL.IO',
  // HTTP mining endpoint
  HttpHost: 'https://testnetpool.pirl.io',
  HttpPort: 8882,

  // Stratum mining endpoint
  StratumHost: 'testnetpool.pirl.io',
  StratumPort: 8002,

  // Fee and payout details
  PoolFee: '0.0%',
  PayoutThreshold: '1.0',
  PayoutInterval: '3h',

  // For network hashrate (change for your favourite fork)
  BlockTime: 13.0,
  BlockReward: 6,
  Unit: 'PIRL',

Install Frontend

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

$ cd official-pirl-testnet-pool/www
$ sudo npm install -g ember-cli@2.9.1
$ sudo npm install -g bower
$ sudo chown -R $USER:$GROUP ~/.npm
$ sudo chown -R $USER:$GROUP ~/.config
$ npm install
$ bower install
//if your going to run as root, you may need to run " bower install --allow-root "
$ ./build.sh
$ note: the build script copies the contents of official-pirl-testnet-pool/www/dist/ to /var/www/

Install nginx configuration

$ a sample config file for nginx is include in the configs directory copy it or edit as directed below
$ sudo nano /etc/nginx/sites-available/default

Modify based on configuration file.

# Default server configuration
# nginx example

upstream api {
    server 127.0.0.1:8080;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    root /var/www;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
    }

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

}

After setting nginx is completed, run the command below.

$ sudo service nginx restart

Type your homepage address or IP address on the web. If you face screen without any issues, pool installation has completed.

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

This guide was originally referred from digitalocean - How To Secure Nginx with Let's Encrypt on Ubuntu 16.04

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! Share your pool link!

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.
• DO NOT OPEN YOUR RPC OR REDIS ON 0.0.0.0!!! It will eventually cause coin theft.
