무료 몽고디비 cloud를 이용해보자

무료 클라우드에 가입하고 스프링 연동을 해보자!

기본적으로 무료 500메가를 제공한다. 몽고디비가 4.x버전위로 업그레이드 되면서 홈페이지가 많이 리뉴얼 된 모습이다.. 엄청 헤맴

아래의 사이트로 접속

1. 홈페이지 접근

Mlab_Homeage

Mlab_Homeage

대충 가입을 누르고 무료 클러스터를 생성해보자

2. Region선택

선택할 때 구글 클라우드를 선택하고 일본 region을 선택하자 한국과 가장 가까움

mlab_cluster_region

3. 총 3개의 노드가 생성되어 올라가고 있다.

중요! 생성하는데 5분정도 걸리니 그냥 기다리자

프라이머리 노드 - 세컨더리 - 세컨더리

waiting

4. db access 유저를 생성

create_user

5. network access 설정

0.0.0.0/0 전역으로 넣자! 물론 테스트이니가 가능한일..

6. 노드가 전부 올라감

all_node_activated

7. mongodb uri 획득

A. Connect 클릭
A

B. connect your application 클릭
B

C. copy 클릭
C

4번에서 설정한 username, password 기입 ( <> 해당 기호 제거)

1
mongodb+srv://<username>:<password>@cluster0.yul3n.gcp.mongodb.net/<dbname>?retryWrites=true&w=majority

8. Spring 설정

build.gradle 디펜던시 추가
