# 2.3.4 커맨드 라인 설정

&#x20; elasticsearch.yml 파일에 설정하는 것 외에도 Elasticsearch 실행 시 커맨드 명령에 `-E <옵션>=<값>` 을 이용해서 환경 설정이 가능합니다. 예를 들어 클러스터명은 **my-cluster** 노드명은 **node-1**로 노드를 실행하기 위해서는 다음과 같이 실행합니.

{% code title="클러스터명: my-cluster / 노드명:  node-1 로 노드 실행" %}

```bash
$ bin/elasticsearch -E cluster.name=my-cluster -E node.name="node-1"

{% endcode %}

{% hint style="warning" %}
환경 설정이 elasticsearch.yml 과 커맨드 명령 -E 에 모두 있는 경우에는 -E 커맨드 명령에서 한 설정이 더 우선해서 적용이 됩니다.
{% endhint %}

&#x20; 지금까지 기본적인 설치 방법과 설정 정보들을 살펴보았습니다. 지금까지 다룬 설정들 외에도 추가적으로 다양한 설정들이 있습니다. 설치와 설정에 대한 더 많은 내용들은 아키텍쳐 구성과 예제 부분에서 더 자세히 다루도록 하겠습니다.
