예상 해결 방법
1. docker로 redis 띄우기
현제 run 중인 container에 redis가 없음
해결 완료 !
해결과정
1. redis 이미지 다운
2. redis run 시키기
하지만 에러 발생
3. lsof 로 확인
lsof 는 list open files 의 약자로 시스템에서 열린 파일 목록을 알려주고 사용하는 프로세스, 디바이스 정보, 파일의 종류등 상세한 정보를 출력해주는 명령어인데,
위와 같이 2줄 상태로 출력 되었다. (redis connection error)
*
* 배포 script에 SPRING_REDIS_HOST 환경변수가 적용되어 있지 않아서 발생했던 connection issue!
*
4. 해결한 뒤 lsof
