# 구축하기

### 시작하기 전에

시작하기 전에 다음을 확인하세요:

* [인프라DID](/infrablockchain-docs/ko/infrablockchain/service-chains/infra-did-parachain.md)

### 인프라DID 체인

이전 튜토리얼을 완료한 경우, 로컬에 ***인프라릴레이체인(InfraRelayChain)*** 레포지토리가 있어야 합니다.

1. 컴퓨터의 터미널 셸을 엽니다.
2. 다음 명령을 실행하여 인프라DID 체인 저장소를 복제합니다:

   ```bash
   git clone https://github.com/InfraBlockchain/infra-did-substrate
   ```

   이 명령은 `develop` 브랜치를 클론합니다.
3. 다음 명령을 실행하여 노드 템플릿 디렉토리의 루트로 이동합니다:

   ```bash
   cd infra-did-substrate
   ```

   작업을 포함할 새 브랜치를 만듭니다:

   ```bash
   git switch -c my-learning-branch-yyyy-mm-dd
   ```

   `yyyy-mm-dd`를 원하는 식별 정보로 바꾸세요. 숫자로 된 연도-월-일 형식을 권장합니다. 예를 들어:

   ```bash
   git switch -c my-learning-branch-2023-03-01
   ```
4. 다음 명령을 실행하여 노드 템플릿을 컴파일합니다:

```bash
cargo build --release
```

최적화된 빌드를 위해 항상 `--release` 플래그를 사용해야 합니다. 처음으로 이를 컴파일하는 경우 완료까지 시간이 다소 소요됩니다.

다음과 유사한 줄이 표시되면 완료됩니다:

```bash
Finished release [optimized] target(s) in 11m 23s
```

### 로컬 노드 시작하기

노드가 컴파일되면 좀비넷을 사용하여 릴레이체인과 인프라DID 체인을 로컬 환경에서 구축 할 준비가 되었습니다.

로컬 인프라DID 체인을 시작하려면 다음 단계를 따르세요:

1. 좀비넷 설정을 확인합니다

   ```bash
   cat ./zombienet/local-dev.toml
   ```

   ```toml
    [relaychain]
    default_command = "../infra-relay-chain/target/release/infrablockspace"
    default_args = ["-lparachain=debug", "-l=xcm=trace"]
    chain = "infrablockspace-local"

    [[relaychain.nodes]]
    name = "alice"
    validator = true
    rpc_port = 7100
    ws_port = 7101

    [[relaychain.nodes]]
    name = "bob"
    validator = true
    rpc_port = 7200
    ws_port = 7201

    [[relaychain.nodes]]
    name = "charlie"
    validator = true
    rpc_port = 7300
    ws_port = 7301

    [[relaychain.nodes]]
    name = "dave"
    validator = true
    rpc_port = 7400
    ws_port = 7401

    [[relaychain.nodes]]
    name = "eve"
    validator = true
    rpc_port = 7500
    ws_port = 7501

    [[relaychain.nodes]]
    name = "ferdie"
    validator = true
    rpc_port = 7600
    ws_port = 7601

    [[parachains]]
    id = 1337
    chain = "infra-did-substrate-local"
    cumulus_based = true

    # run alice as parachain collator
    [[parachains.collators]]
    name = "alice"
    validator = true
    command = "./target/release/infradid"
    args = ["-lparachain=debug", "--alice"]
   ```

   `relaychain`과 `parachains`의 `default_command` 경로가 실제 로컬에 존재하는 경로와 일치하는지 확인합니다.

   만약 일치하지 않는다면 로컬 환경에 맞게 변경 해 줍니다.
2. 좀비넷을 실행하여 릴레이체인과 체인을 실행합니다.

   ```shell
   zombienet spawn --provider native zombienet/local-dev.toml
   ```
3. 정상적으로 실행 되었다면 다음과 유사한 터미널 쉘을 확인할 수 있습니다.

   ![zombienet](/files/q2MCIe73Lw3GQUCPcYFn)
4. (선택) 인프라DID 체인의 노드를 확인하면 아래와 유사한 로그를 확인할 수 있습니다.

   ```shell

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.infrablockchain.net/infrablockchain-docs/ko/infrablockchain/tutorials/service-chains/infra-did-parachain/build.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
