-0. MongoDB란
MongoDB는 document-oriented NoSQL 계열 오픈소스 데이터베이스로 아래와 같은 구조로 이루어집니다.
(출처: https://beginnersbook.com/2017/09/mapping-relational-databases-to-mongodb/)
Document
=> Document는 기존 RDBMS 의 record 와 같은 개념으로 실제 데이터가 저장되는 방식이며 JSON 형태의 key-value 쌍으로 이루어져 있음
value에는 array, string, int 등 다양한 type 이 올 수 있음

}
Collection
=> RDBMS 의 테이블과 같은 개념
database
=> mysql 의 스키마와 같은 개념으로 MongoDB 서버는 여러개의 database로 이루어 질 수 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 및 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

-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
