목표 : mysql 서버를 다운받고 이것저것 작업해본다
어디서 : 우분투, cmd 등에서
어떻게 : 리눅스 명령어를 입력해서

3. mysql root의 비밀번호 찾아보기
- MySQL 컨테이너의 로그에서 표준에러(2)를 표준 출력(1)으로 가져오고, 이를 다시 grep GENERATED 명령어로 전달하여 "GENERATED" 라는 문자열이 포함된 라인을 찾습니다.
weare@DESKTOP-BE1I4GE:~$ docker logs mysql_container 2>&1|grep GENERATED
[Entrypoint] GENERATED ROOT PASSWORD: +4ua5uBgh#vIo=8?;?88JCueH/q61o0/
+A | B : A명령어를 B에 전달
+ & : 리다이렉트하는 역할
4. 구한 비밀번호 이용해서 mysql shell 열어보기
- weare@DESKTOP-BE1I4GE:~$ docker exec -it mysql_container mysql -uroot -p
- it : Docker 컨테이너를 interactive(대화형) 모드로 실행하고 터미널에 연결할 때 사용
- docker exec: 이 명령은 실행 중인 컨테이너 내에서 명령을 실행할 수 있게 합니다.
- -it: 이 옵션들은 대화형 터미널을 사용하여 명령을 실행할 수 있게 합니다.
- mysql_container: 이는 명령을 실행할 MySQL 컨테이너의 이름입니다.
- mysql -uroot -p: 이는 MySQL 명령행 클라이언트 명령입니다. 지정된 사용자 (-uroot는 root 사용자를 나타냄)로 MySQL 서버에 연결하고 비밀번호를 입력하도록 요청합니다.
-p 는 비밀번호를 요청

5. 임시비밀번호에서 원하는 비밀번호로 변경
- mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

6. 데이터 베이스 구경
- 데이터 베이스가 4개 저장돼있는것 확인
mysql> show databases

7. 사용한 명령어 몇개 살펴보기
docker run --name : 사용하기 편한 컨테이너 아이디 지정
docker logs : container쪽에서 생성된 stdout, stderr단의 로그를 읽어옴, --follow 사용시 로그 계속적으로 스트리밍됨
