Pool Design/Theory

The core daemons are:

api - Main API for the frontend to use and pull data from.  Expects to be hosted at  /
remoteShare - Main API for consuming shares from remote/local pools.  Expects to be hosted at /leafApi
pool - Where the miners connect to.
longRunner - Database share cleanup.
payments - Handles all payments to workers.
blockManager - Unlocks blocks and distributes payments into MySQL
worker - Does regular processing of statistics and sends status e-mails for non-active miners.

Server Requirements

• Ubuntu 16.04 (fresh installation)
• 4 Gb Ram
• 2 CPU Cores (with AES_NI)
• 60 Gb SSD-Backed Storage (not set in stone)

Pre-Installation (one liner)

/usr/sbin/useradd -m graft && echo "graft ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers && passwd graft

Interactive Installer (one liner)

• Login as the new user: sudo su - graft

wget https://raw.githubusercontent.com/sysrenan/nodejs-pool/master/deployment/deploy.bash?${RANDOM} -O deploy.bash && chmod +x deploy.bash && ./deploy.bash

Wallet

The pool is designed to have a dual-wallet design, one which is a fee wallet, one which is the live pool wallet. The fee wallet is the default target for all fees owed to the pool owner.

The deploy script will automatically create both wallets. You will enter a wallet name during installation and the script will append -pool and -fee to the wallet as well as to the ~/walletpass file. The password will be the same for both wallets, feel free to change as needed.

The wallet location will be: ~/<walletname>-fee or ~/<walletname>-pool

Final Manual Steps

• From the admin panel, you can configure all of your pool's settings for addresses, payment thresholds, etc.
• Configure email option:

UPDATE pool.config SET item_value = 'key-xxxxxxxx' WHERE module = 'general' and item = 'mailgunKey';
UPDATE pool.config SET item_value = 'https://api.mailgun.net/v3/xxxxxxx' WHERE module = 'general' and item = 'mailgunURL';

Configuration Details

You should take a look at the original wiki for specific configuration settings in the system.
