1. 사전 환경 세팅
1) JDK 설치
Java 17을 기준으로 구성된 Spring Boot 서버를 실행시킬 예정이다. Spring Boot 서버를 실행시키려면 JDK 가 설치되어 있어야 한다. 따라서 JDK 17 버전을 설치한다.

서버를 실행시키기 전에 먼저 빌드를 해야 한다.
기존에 빌드된 파일을 삭제하고 새롭게 JAR 로 빌드한 뒤 ~/linux-springboot/build/libs 경로에서 Spring Boot 프로젝트를 실행시킨다.
로그가 터미널 화면에 출력된 것을 확인할 수 있다.
Spring Boot 출력되는 로그가 표준 출력, 표준 에러 출력으로 전달되면 터미널에 기본값으로 출력하게끔 세팅되어 있기 때문에 터미널에 로그가 나오는 것을 확인할 수 있다.
2. Spring Boot 서버가 출력하는 로그를 파일로 남기기
1) 실행시킨 서버 종료
Ctrl + c 를 누르면 종료된다.

2) 표준 출력과 표준 에러 출력을 파일로 리다이렉션
- Ubuntu
ubuntu@ip-172-31-39-75:~/linux-springboot/build/libs$ java -jar linux-springboot-0.0.1-SNAPSHOT.jar >> app.log 2>&1
표준 출력과 표준 에러 출력에서 발생하는 값을 app.log 파일로 전송하기 위해, 2>&1 을 활용했고, Spring Boot 를 실행시킬 때마다 기존 로그 파일의 내용이 삭제되지 않게 > 대신에 >> 를 사용했다.
참고)
2>&1 은 표준 에러(파일 디스크립터 2번)를 표준 출력(파일 디스크립터 1번)과 동일한 곳으로 리다이렉션하라는 의미
3) 로그가 파일에 잘 저장됐는 지 확인
Ctrl + c 를 눌러 서버를 종료시킨 후 로그 파일을 확인한다.

기존 로그가 사라지지 않고 계속해서 쌓이게끔 만들었다.
실제 현업에서 서비스를 운영할 때, 출력되는 로그를 터미널 화면에서 보게끔 만들지 않고 파일로 저장한다. 나중에 문제가 생겼을 때 로그 파일을 열어서 디버깅을 하기 때문이다.
