I need help to build my own node on ubuntu

[Pep-73]

I've been using chatgpt to help me out to build my own mining pool using ubuntu+miningcore,
when I run the command sudo nano logs emark --follow, anything happens, I've got already my minig pool fixedcoin, when I adding emark config.json, the pool goes into "maintenace", I konow something is wrong there, but I can't find any solution

Perfect! Let’s create a full Docker Compose stack that runs:

1. eMark daemon (eMarkd)
2. Miningcore
3. Configured for a solo mining pool
4. Persistent volumes, auto-restart, ready to connect miners

Here’s a production-ready setup.

---

Step 1: Create the project folder

mkdir emark-pool && cd emark-pool

---

Step 2: Create docker-compose.yml

version: "3.9"

services:
  emarkd:
    build: ./emarkd
    container_name: emarkd
    restart: unless-stopped
    ports:
      - "7777:7777"   # RPC port
      - "7778:7778"   # P2P port
    volumes:
      - ./emark-data:/root/.eMark
    command: >
      eMarkd
      -rpcallowip=0.0.0.0/0
      -rpcuser=demrpc
      -rpcpassword=ChangeMeStrongPassword
      -server=1
      -daemon=0

  miningcore:
    image: ghcr.io/coinfoundry/miningcore:latest
    container_name: miningcore
    restart: unless-stopped
    depends_on:
      - emarkd
    volumes:
      - ./config:/config
    ports:
      - "4000:4000"   # Stratum port
      - "4001:4001"   # Optional Stratum port
    command: >
      dotnet Miningcore.dll -c /config/config.json

---

Step 3: Create Dockerfile for eMarkd

Folder: emarkd/Dockerfile

FROM ubuntu:22.04

RUN apt-get update && apt-get install -y \
    git build-essential libssl-dev libdb++-dev \
    libboost-all-dev libprotobuf-dev libqrencode-dev \
    libminiupnpc-dev curl \
 && apt-get clean && rm -rf /var/lib/apt/lists/*

WORKDIR /opt/emark
RUN git clone https://github.com/emarkproject/eMark.git .
WORKDIR /opt/emark/src
RUN make -f makefile.unix
RUN cp eMarkd /usr/local/bin/

VOLUME ["/root/.eMark"]
WORKDIR /root/.eMark

EXPOSE 7777 7778
CMD ["eMarkd", "-rpcallowip=0.0.0.0/0", "-rpcuser=demrpc", "-rpcpassword=ChangeMeStrongPassword", "-server=1", "-daemon=0"]

---

Step 4: Create Miningcore configuration

Create folder: config/coins/

File: config/coins/emark.json

{
  "name": "emark",
  "symbol": "DEM",
  "family": "bitcoin",
  "hash": "sha256d",
  "rpcPort": 7777,
  "blockTime": 120,
  "blockReward": 25,
  "p2pPort": 7778,
  "targetSpacing": 120,
  "maxMoney": 210000000,
  "addressPrefixes": {
    "pubKey": [34],
    "script": [5]
  },
  "magic": "0xFBC0B6DB"
}

File: config/config.json

{
  "logging": { "level": "info", "console": true },
  "pools": [
    {
      "id": "emark-solo",
      "enabled": true,
      "coin": "emark",
      "address": "YOUR_PAYOUT_ADDRESS",
      "poolFeePercent": 0.0,
      "blockRefreshInterval": 500,
      "jobRebroadcastTimeout": 10,
      "connection": { "port": 4000, "bind": "0.0.0.0" },
      "daemons": [
        { "host": "emarkd", "port": 7777, "user": "demrpc", "password": "ChangeMeStrongPassword" }
      ],
      "paymentProcessing": { "enabled": true, "minimumConfirmations": 10, "payoutInterval": 600 }
    }
  ],
  "api": { "enabled": false },
  "stratum": { "enabled": true }
}

🔹 Replace YOUR_PAYOUT_ADDRESS with your actual eMark address.
🔹 The magic and addressPrefixes match the DEM chain defaults. If your chain differs, adjust accordingly.

---

Step 5: Start the stack

docker compose up -d

• eMarkd will sync the blockchain in ./emark-data
• Miningcore will start a solo pool listening on port 4000 for miners

Check logs:

docker logs -f emarkd
docker logs -f miningcore

---

Step 6: Connect a miner

cpuminer -a sha256d \
-o stratum+tcp://YOUR_SERVER_IP:4000 \
-u YOUR_PAYOUT_ADDRESS -p x

---

✅ You now have a complete eMark solo mining pool stack in Docker.
It’s persistent, auto-restarting, and ready for miners.

---

If you want, I can also add a monitoring dashboard with Grafana + Prometheus so you can see live pool stats and miner shares inside the same Docker Compose.

Do you want me to add that?
