# 체크와 업데이트
sudo apt update && sudo apt-get -y upgrade
# mariadb 설치
sudo apt-get install -y mariadb-server
2) 계정/비번 설정 하는 방법
# 입력 없이 접속
sudo mysql
# 비번 설정 및 권한 부여
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '비밀번호' WITH GRANT OPTION;
# 적용
FLUSH PRIVILEGES;
3) Mariadb 설정 파일 편집
1. port 설정
2. 외부 접속 허용
3. 새로 추가된 ebs 볼륨 연결
# 데이터를 저장하고 싶은 위치에 폴더 생성
sudo mkdir -p /ddrive/mariadb-data
# mariadb stop 후
sudo service mysql stop
# 데이터 copy
sudo cp -R /var/lib/mysql/* /ddrive/mariadb-data/
# 해당 폴더에 권한 부여
sudo chown -R mysql:mysql /ddrive/mariadb-data
# 환경 설정 파일 편집
sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf
# 편집 후
sudo systemctl restart mariadb
# 파일 생성 후 내용 저장

# 설치 시작
sudo yum install -y mongodb-org
2. MongoDB 데이터 삽입 공간 변경
# 빈 폴더 생성
sudo mkdir -p /xvdb/mongodb/data/mongo
# 추가 된 스토리지 경로로 설치된 mongo 폴더 카피
cp -ra /var/lib/mongo /xvdb/mongodb/data/mongo
# conf파일 열기
sudo vi /etc/mongod.conf
# 추가 된 스토리지 경로로 dbPath 변경
storage:
dbPath: /xvdb/mongodb/data/mongo
# 외부에서 접속할 수 있도록 net 변경
net:
port: 27017
bindIp: 0.0.0.0
# 권한 부여
sudo chown mongod:mongod /xvdb/mongodb/data/mongo
3. MongoDB 시작
# MongoDB 실행 확인 (없는 거 확인)
ps -ef | grep mongo
# 몽고 디비 실행
sudo systemctl start mongod
# 몽고 디비 상태 확인
sudo systemctl status mongod
# 접속 확인
mongo 혹은 netstat -ano | grep mongo
cd /opt/aws/amazon-cloudwatch-agent/bin/

4) Log는 모니터링하지 않고 CPU, 메모리만 나오도록 진행합니다.
