Running Miningcore on Windows

• .Net Core 3.1 Runtime
• PostgreSQL Database v12 or higher
• Coin Daemon (per pool)

Running pre-built Release Binaries on Windows

• Download miningcore-win-x64.zip from the latest Release
• Extract the Archive
• Setup the database as outlined below
• Create a configuration file config.json as described here
• Run dotnet Miningcore.dll -c config.json

Running Miningcore on Linux

• Install .Net Core 3.1 SDK

  Example Ubuntu 20.04:

wget https://packages.microsoft.com/config/ubuntu/20.10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y dotnet-sdk-3.1

• Install PostgreSQL Database v12 or higher

  Example Ubuntu 20.04:

# Create the file repository configuration:
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

# Import the repository signing key:
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

# Update the package lists:
sudo apt-get update

# Install the latest version of PostgreSQL.
# If you want a specific version, use 'postgresql-12' or similar instead of 'postgresql':
sudo apt-get -y install postgresql-12

• Create the database config:

# login as postgres user
sudo -i -u postgres
psql

CREATE USER miningcore WITH ENCRYPTED PASSWORD 'some-secure-password';
CREATE DATABASE miningcore;
ALTER DATABASE miningcore OWNER TO miningcore;
ALTER USER postgres WITH PASSWORD 'new_password';
GRANT ALL privileges ON DATABASE miningcore TO miningcore;

list shows the databases and privileges like below:

(4 rows)

# exit PostgresDB
\quit

# exit user postgres
$ exit					

• Import Miningcore database tables

sudo wget https://raw.githubusercontent.com/minernl/miningcore/master/src/Miningcore/DataStore/Postgres/Scripts/createdb.sql

sudo -u postgres -i
psql -d miningcore -f createdb.sql
exit

• Advanced PostgreSQL Database setup

The following step needs to performed once for every new coin you add to your server or cluster. Be sure to replace all occurences of pools_id in the statement below with the id of your pool from your config.json file:

sudo -u postgres -i
psql -d miningcore

CREATE TABLE shares_pools_id PARTITION OF shares FOR VALUES IN ('pools_id');

!!! Do this for every Coin you add to you server. If you have multiple server, add it on every server !!!

EXAMPLE:

lookup for the pools id in you config.json file. In this example pools id is VerusCoin

  CREATE TABLE shares_VerusCoin PARTITION OF shares FOR VALUES IN ('VerusCoin');
  
  config.json:
  "pools": [
      {
        "id": "VerusCoin",
        "enabled": true,
        "coin": "VerusCoin",
        "address": "RE9v8tCKiALVmkWbirTKc5cZpSJtuXswJ8",

• Coin Daemon (per pool)

• Miningcore needs to be built from source on Linux.

  Example Ubuntu 20.04:

sudo apt-get update -y
sudo apt-get install git cmake build-essential libssl-dev pkg-config libboost-all-dev libsodium-dev libzmq5
sudo git clone https://github.com/minernl/miningcore
cd miningcore/src/Miningcore
dotnet publish -c Release --framework netcoreapp3.1  -o ../../build

• Running Miningcore

  Create a configuration file config.json as described here

cd ../../build
dotnet Miningcore.dll -c config.json

Configuration

API

Building on Windows

Download and install the .Net Core 3.1 SDK

git clone https://github.com/minernl/miningcore
cd miningcore/src/Miningcore
dotnet publish -c Release --framework netcoreapp3.1  -o ..\..\build

Building on Windows - VISUAL STUDIO

• Download and install the .Net Core 3.1 SDK
• Install Visual Studio 2019. Visual Studio Community Edition is fine.
• Open Miningcore.sln in VS 2019

Running a production pool

Running Miningcore

Create a configuration file config.json as described here

cd ../../build
dotnet Miningcore.dll -c config.json

A public production pool requires a web-frontend for your users to check their hashrate, earnings etc. You can use the web frontend that come with this fork Miningcore.Web

ShareRelay (ZeroMQ) needs .NET core 2.1 runtime

ZeroMQ is not supported in .NET core 3.1 and ShareRelay will fail

If you need ShareRelay support:

Install dotnet-sdk-2.1

sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y dotnet-sdk-2.1

Build pool in core2.1 framework

BUILDIR=${1:-../../build}
echo "Building into $BUILDIR"
dotnet publish -c Release --framework netcoreapp2.1 --runtime linux-x64 --self-contained true -o $BUILDIR
