-0. MongoDB란

 

MongoDB document-oriented NoSQL 계열 오픈소스 데이터베이스로 아래와 같은 구조로 이루어집니다.

(출처: https://beginnersbook.com/2017/09/mapping-relational-databases-to-mongodb/)

 

Document

=> Document 기존 RDBMS record 같은 개념으로 실제 데이터가 저장되는 방식이며 JSON 형태의 key-value 쌍으로 이루어져 있음

value에는 array, string, int 다양한 type 있음

{

name : "kimdubi",

age : 29,

interests : ["Infra","DB","NoSQL"]

}

 

Collection

=> RDBMS 테이블과 같은 개념

 

database 

=> mysql 스키마와 같은 개념으로 MongoDB 서버는 여러개의 database 이루어 있으며 database 안에는 여러개의 Collection들이 있습니다.

 

-1. 사용할 디렉토리 생성

 

/engn001/mongo => mongodb 엔진영역

/data001/mongo => mongodb data 영역

 

 

-2. 계정 profile 수정

 

export MONGO_PATH=/engn001/mongo/

export PATH=$PATH:$MONGO_PATH/bin

 

-3. mongodb tar 압축해제 설치

 

dori:mongo mac$ pwd

/engn001/mongo

dori:mongo mac$ ls

mongodb-osx-ssl-x86_64-4.0.9.tar

 

-3.1. mongodb conf 파일 생성

vi mongod.conf

 

systemLog:    ## db log 관련설정

  destination: file

  path: "/engn001/mongo/logs"

  logAppend: true   ## 새로운 로그를 기존 로그파일에 추가하는 방식

  verbosity: 0  ## 로깅 레벨로 0~5. 이슈 발생  디버깅 하려면 레벨을 높게 설정하는  좋음

storage:
  dbPath:   ## db data 저장될 위치 지정
    "/data001/mongo"

  journal:   ## transaction log 사용 유무 = mysql log-bin 옵션

    enabled: true

    commitIntervalMs: 100   ## 커밋 인터발

  directoryPerDB: true  ## database 별로 디렉토리 별도로 사용

  wiredTiger:   ## mongodb 에서 사용할 엔진 설정 wiredTiger  mmapv1 / inMemory 엔진  있음

    engineConfig:

      cacheSizeGB: 2  ## buffer pool 사이즈

      journalCompressor: snappy  ## journal data 압축 방식 ( none / snappy - default / zlib )

      directoryForIndexes: false  ## true 설정  storage.dbPath 아래 index / collection 디렉토리에 각각 인덱스와 컬렉션을 저장함

    collectionConfig:

      blockCompressor: snappy

    indexConfig:

      prefixCompression: true

processManagement:

  fork: true  ## mongodb 데몬형태로 띄움

net:

  bindIp: 127.0.0.1

  port: 27017

 

 

 

-4. mongodb 기동

 

dori:mongo mac$ vi mongod.cfg
dori:mongo mac$ mongod --config=/engn001/mongo/mongod.cfg
about to fork child process, waiting until server is ready for connections.
forked process: 24596
child process started successfully, parent exiting

dori:mongo mac$

 

 

 

-5. log 확인
