노드 설치

계정을 생성하였으면 다음으로 Gesia 네트워크를 구성하고 있는 genesis 파일이 필요합니다.

Genesis JSON 파일 생성

각 네트워크별 genesis.json 파일은 아래와 같습니다.

네트워크 초기화

이제 네트워크를 초기화하기 위해 아래와 같은 Docker Compose 파일을 생성합니다.

docker-compose-geth-init.yml

version: '3'services:  init:    image: ethereum/client-go    command: init /root/.ethereum/genesis.json    volumes:      - ./node:/root/.ethereum

파일을 생성한 후, 아래 명령어로 실행합니다.

$ docker-compose -f docker-compose-geth-init.yml up

파일을 실행하면 geth 디렉토리가 생성되며, 이 디렉토리에는 genesis 블록과 초기 네트워크 구성이 저장됩니다.

Geth 실행

이제 geth를 실행하기 위해 아래와 같은 Docker Compose 파일을 생성합니다.

unlock과 miner.etherbase 옵션에는 기존에 생성한 지갑 주소를 입력합니다.

docker-compose.yml

version: '3.8'services:  node:    image: ethereum/client-go:v1.13.11    container_name: node    command: --datadir="/root/.ethereum"      --syncmode="full"      --gcmode="archive"      --port=30303      --http      --http.addr="0.0.0.0"      --http.port=8501      --http.corsdomain="*"      --http.api="personal,miner,eth,net,txpool,debug,clique"      --http.vhosts="*"      --ws      --ws.addr="0.0.0.0"      --ws.port=8502      --ws.api="personal,miner,eth,net,txpool,debug,clique"      --networkid=5555      --verbosity=5      --unlock="88bA2E9BC988506C3F588493EdC53Acaf52a9Faf"      --password=/root/.ethereum/password      --miner.gasprice=0      --miner.etherbase="88bA2E9BC988506C3F588493EdC53Acaf52a9Faf"      --allow-insecure-unlock      --nodiscover      --mine    volumes:      - ./node:/root/.ethereum:rw    ports:      - '30303:30303'      - '8501:8501'      - '8502:8502'    networks:      - gesia-network​networks:  gesia-network:    driver: bridge

파일을 생성한 후, 아래 명령어로 실행합니다.

$ docker-compose up

여기까지 실행을 완료하였으면, 정상적으로 노드 설치가 마무리 되었습니다.
