V: Chạy Midnight Node Validator

1. Yêu Cầu:

DB_SYNC và POSTGRES cần có cổng truy cập được dành cho Midnight Node và đã đồng bộ đầy đủ Thiết lập các phụ thuộc của chuỗi đối tác.

SEED_PHRASE của khóa cross-chain được tạo ở Bước Đăng ký làm Validator node..

NODE_KEY được tạo ở Bước Đăng ký làm Validator node.

Midnight Node hiện có sẵn dưới dạng một image Docker, do đó cần cài đặt Docker/Docker Compose.

2. Chạy Midnight Node validator với docker compose

Một kho lưu trữ docker-compose được cung cấp để dễ dàng khởi động midnight-node trên testnet

git clone https://github.com/midnight-ntwrk/partner-chain-deps-docker.git
cd midnight-node-docker 
ls .

Folder dự án này bao gồm tệp .env chứa các biến môi trường quan trọng cần chỉnh sửa.

3. Cập nhập biến môi trường.

– Mở tệp .env bằng trình soạn thảo nano hoặc vi

– Cập nhập DB_SYNC_POSTGRES_CONNECTION_STRING với địa chỉ IP/host và mật khẩu chính xác của bạn.

– Tạo NODE_KEY bằng lệnh bên dưới sau đó cập nhập vào tệp .env

docker run --rm -it docker.io/parity/subkey:latest generate-node-key

– Sao chép SEED_PHRASE được tạo ở bước “Đăng ký làm Validator node” của bạn vào container

docker cp /home/YOUR_USER/partner-chains-cli/data/chains/partner_chains_template/keystore/ midnight-node-docker-midnight-node-testnet-1:./node/chain/chains/testnet

4. Khởi động Midnight Node bằng docker-compose:

Trong cùng thư mục với tệp compose.yml, thực thi lệnh sau để bắt đầu chạy node:

docker-compose up

– Node sẽ bắt đầu kết nối với testnet đồng bộ và thực hiện xác thực các block.

Ví dụ về logs đúng khi node đã đóng block thành công, lưu ý cần chờ n+2 epoch khi đăng ký làm validator thành công.

Trong cùng thư mục với tệp compose.yml, thực thi lệnh sau để kiểm tra logs.
