+# KAMCO Training API 배포 가이드 (RedHat 9.6)
+
+## 빠른 배포 (Quick Start)
+
+이 문서는 RedHat 9.6 환경에서 HTTPS로 KAMCO Training API를 배포하는 방법을 설명합니다.
+
+**접속 URL**:
+- `https://api.train-kamco.com`
+- `https://train-kamco.com`
+
+## 사전 요구사항
+
+- [x] Docker & Docker Compose 설치
+- [x] Git 설치
+- [x] sudo 권한
+- [x] 포트 80, 443 사용 가능
+
+## 1단계: /etc/hosts 설정
+
+```bash
+# root 권한으로 도메인 추가
+echo "127.0.0.1   api.train-kamco.com train-kamco.com" | sudo tee -a /etc/hosts
+
+# 확인
+cat /etc/hosts | grep train-kamco
+```
+
+**예상 결과**:
+```
+127.0.0.1   api.train-kamco.com train-kamco.com
+```
+
+## 2단계: 방화벽 설정 (필요시)
+
+```bash
+# 방화벽 상태 확인
+sudo firewall-cmd --state
+
+# HTTP/HTTPS 포트 개방
+sudo firewall-cmd --permanent --add-port=80/tcp
+sudo firewall-cmd --permanent --add-port=443/tcp
+
+# 방화벽 재로드
+sudo firewall-cmd --reload
+
+# 확인
+sudo firewall-cmd --list-ports
+```
+
+**예상 결과**: `80/tcp 443/tcp`
+
+## 3단계: 프로젝트 디렉토리로 이동
+
+```bash
+cd /path/to/kamco-train-api
+
+# 현재 위치 확인
+pwd
+# 예상: /home/username/kamco-train-api
+```
+
+## 4단계: 파일 구조 확인
+
+배포 전 필수 파일이 모두 있는지 확인하세요:
+
+```bash
+# SSL 인증서 확인
+ls -la nginx/ssl/
+
+# 예상 결과:
+# train-kamco.com.crt (인증서)
+# train-kamco.com.key (개인 키)
+# openssl.cnf (설정 파일)
+```
+
+```bash
+# Docker Compose 파일 확인
+ls -la docker-compose-prod.yml nginx/nginx.conf
+
+# 예상: 두 파일 모두 존재
+```
+
+## 5단계: Docker 네트워크 생성 (최초 1회)
+
+```bash
+# kamco-cds 네트워크가 있는지 확인
+docker network ls | grep kamco-cds
+
+# 없으면 생성
+docker network create kamco-cds
+```
+
+## 6단계: Docker Compose 배포
+
+```bash
+# 기존 컨테이너 중지 (있는 경우)
+docker-compose -f docker-compose-prod.yml down
+
+# 새로운 이미지 빌드 및 실행
+docker-compose -f docker-compose-prod.yml up -d --build
+
+# 컨테이너 상태 확인
+docker-compose -f docker-compose-prod.yml ps
+```
+
+**예상 결과**:
+```
+NAME                      STATUS
+kamco-cd-nginx           Up (healthy)
+kamco-cd-training-api    Up (healthy)
+```
+
+## 7단계: 배포 확인
+
+### 컨테이너 로그 확인
+
+```bash
+# Nginx 로그
+docker logs kamco-cd-nginx --tail 50
+
+# API 로그
+docker logs kamco-cd-training-api --tail 50
+
+# 실시간 로그 (Ctrl+C로 종료)
+docker-compose -f docker-compose-prod.yml logs -f
+```
+
+### HTTP → HTTPS 리다이렉트 테스트
+
+```bash
+# HTTP 접속 시 HTTPS로 리다이렉트되는지 확인
+curl -I http://api.train-kamco.com
+curl -I http://train-kamco.com
+
+# 예상 결과: 301 Moved Permanently
+# Location: https://api.train-kamco.com/ 또는 https://train-kamco.com/
+```
+
+### HTTPS 헬스체크
+
+```bash
+# -k 플래그: 사설 인증서 경고 무시
+curl -k https://api.train-kamco.com/monitor/health
+curl -k https://train-kamco.com/monitor/health
+
+# 예상 결과: {"status":"UP","components":{...}}
+```
+
+### 브라우저 테스트
+
+브라우저에서 다음 URL에 접속:
+
+- `https://api.train-kamco.com/monitor/health`
+- `https://train-kamco.com/monitor/health`
+
+**사설 인증서 경고**:
+- "안전하지 않음" 경고가 표시되면 **"고급"** → **"계속 진행"** 클릭
+
+## 8단계: SSL 인증서 확인 (선택사항)
+
+```bash
+# 인증서 정보 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -text -noout | head -30
+
+# 유효 기간 확인 (100년)
+openssl x509 -in nginx/ssl/train-kamco.com.crt -noout -dates
+
+# SAN (멀티 도메인) 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -text -noout | grep -A1 "Subject Alternative Name"
+
+# 예상 결과:
+# X509v3 Subject Alternative Name:
+#     DNS:api.train-kamco.com, DNS:train-kamco.com
+```
+
+## 트러블슈팅
+
+### 문제 1: "Connection refused"
+
+**원인**: 컨테이너가 실행되지 않음
+
+**해결**:
+```bash
+# 컨테이너 상태 확인
+docker ps -a | grep kamco-cd
+
+# 컨테이너 재시작
+docker-compose -f docker-compose-prod.yml restart
+
+# 로그 확인
+docker logs kamco-cd-nginx
+docker logs kamco-cd-training-api
+```
+
+### 문제 2: "502 Bad Gateway"
+
+**원인**: Nginx는 실행 중이지만 API 컨테이너가 준비되지 않음
+
+**해결**:
+```bash
+# API 컨테이너 상태 확인
+docker logs kamco-cd-training-api
+
+# API 헬스체크 (컨테이너 내부에서)
+docker exec kamco-cd-nginx wget -qO- http://kamco-changedetection-api:8080/monitor/health
+
+# API 컨테이너 재시작
+docker-compose -f docker-compose-prod.yml restart kamco-changedetection-api
+```
+
+### 문제 3: "Name or service not known"
+
+**원인**: /etc/hosts에 도메인이 설정되지 않음
+
+**해결**:
+```bash
+# /etc/hosts 확인
+cat /etc/hosts | grep train-kamco
+
+# 없으면 추가
+echo "127.0.0.1   api.train-kamco.com train-kamco.com" | sudo tee -a /etc/hosts
+```
+
+### 문제 4: 포트 80 또는 443이 이미 사용 중
+
+**원인**: 다른 프로세스가 포트를 사용 중
+
+**해결**:
+```bash
+# 포트 사용 확인
+sudo lsof -i :80
+sudo lsof -i :443
+
+# 사용 중인 프로세스 종료 (예: httpd, nginx)
+sudo systemctl stop httpd
+sudo systemctl stop nginx
+
+# Docker Compose 재시작
+docker-compose -f docker-compose-prod.yml restart
+```
+
+### 문제 5: SELinux 권한 오류
+
+**원인**: SELinux가 Docker 볼륨 마운트를 차단
+
+**해결**:
+```bash
+# SELinux 상태 확인
+getenforce
+
+# Permissive 모드로 임시 변경 (재부팅 시 초기화됨)
+sudo setenforce 0
+
+# 영구 변경 (권장하지 않음)
+sudo vi /etc/selinux/config
+# SELINUX=permissive 또는 SELINUX=disabled로 변경
+```
+
+## 컨테이너 관리 명령어
+
+### 시작/중지/재시작
+
+```bash
+# 시작
+docker-compose -f docker-compose-prod.yml up -d
+
+# 중지
+docker-compose -f docker-compose-prod.yml down
+
+# 재시작
+docker-compose -f docker-compose-prod.yml restart
+
+# 특정 서비스만 재시작
+docker-compose -f docker-compose-prod.yml restart nginx
+docker-compose -f docker-compose-prod.yml restart kamco-changedetection-api
+```
+
+### 로그 확인
+
+```bash
+# 전체 로그
+docker-compose -f docker-compose-prod.yml logs
+
+# 특정 서비스 로그
+docker-compose -f docker-compose-prod.yml logs nginx
+docker-compose -f docker-compose-prod.yml logs kamco-changedetection-api
+
+# 실시간 로그
+docker-compose -f docker-compose-prod.yml logs -f
+
+# 마지막 N줄만 보기
+docker logs kamco-cd-nginx --tail 100
+```
+
+### 컨테이너 상태 확인
+
+```bash
+# 실행 중인 컨테이너
+docker-compose -f docker-compose-prod.yml ps
+
+# 상세 정보
+docker inspect kamco-cd-nginx
+docker inspect kamco-cd-training-api
+
+# 리소스 사용량
+docker stats kamco-cd-nginx kamco-cd-training-api
+```
+
+### 컨테이너 내부 접속
+
+```bash
+# Nginx 컨테이너 내부 접속
+docker exec -it kamco-cd-nginx sh
+
+# API 컨테이너 내부 접속
+docker exec -it kamco-cd-training-api sh
+
+# 내부에서 빠져나오기
+exit
+```
+
+## 업데이트 및 재배포
+
+### 코드 업데이트 후 재배포
+
+```bash
+# 1. Git pull (코드 업데이트)
+git pull origin develop
+
+# 2. JAR 파일 빌드 (Jenkins에서 수행하는 경우 생략)
+./gradlew clean build -x test
+
+# 3. 컨테이너 재빌드 및 재시작
+docker-compose -f docker-compose-prod.yml down
+docker-compose -f docker-compose-prod.yml up -d --build
+
+# 4. 로그 확인
+docker-compose -f docker-compose-prod.yml logs -f
+```
+
+### 설정 파일만 변경한 경우
+
+```bash
+# nginx.conf 또는 docker-compose-prod.yml 변경 시
+docker-compose -f docker-compose-prod.yml down
+docker-compose -f docker-compose-prod.yml up -d
+
+# 또는
+docker-compose -f docker-compose-prod.yml restart nginx
+```
+
+## 모니터링
+
+### 헬스체크 엔드포인트
+
+```bash
+# API 헬스체크
+curl -k https://api.train-kamco.com/monitor/health
+
+# 예상 결과:
+# {
+#   "status": "UP",
+#   "components": {
+#     "db": {"status": "UP"},
+#     "diskSpace": {"status": "UP"}
+#   }
+# }
+```
+
+### 시스템 리소스
+
+```bash
+# 디스크 사용량
+df -h
+
+# 메모리 사용량
+free -h
+
+# Docker 이미지 및 컨테이너 용량
+docker system df
+```
+
+## 보안 권장 사항
+
+1. **사설 인증서**: 현재 사설 인증서를 사용 중입니다. 프로덕션 환경에서는 **Let's Encrypt** 또는 **GlobalSign** 같은 공인 인증서 사용을 권장합니다.
+
+2. **방화벽**: 필요한 포트(80, 443)만 개방하고, 불필요한 포트는 차단하세요.
+
+3. **정기 업데이트**: Docker 이미지와 시스템 패키지를 정기적으로 업데이트하세요.
+
+4. **로그 모니터링**: 정기적으로 로그를 확인하여 비정상적인 활동을 감지하세요.
+
+5. **백업**: SSL 인증서 키 파일(`train-kamco.com.key`)과 데이터베이스를 정기적으로 백업하세요.
+

+docker-compose -f docker-compose-prod.yml restart
+
+# 로그 확인
+docker-compose -f docker-compose-prod.yml logs -f
+```
+
+---
+
+## 롤백 절차
+
+### 이미지 기반 롤백
+
+```bash
+# 1. 사용 가능한 이미지 확인
+docker images | grep kamco-train-api
+
+# 2. 이전 이미지 태그로 롤백
+export IMAGE_TAG=previous-commit-hash
+docker-compose -f docker-compose-prod.yml up -d
+
+# 3. 헬스체크 확인
+curl -f http://localhost:8080/monitor/health
+```
+
+### Git 기반 롤백
+
+```bash
+# 1. 이전 커밋으로 체크아웃
+git log --oneline -10
+git checkout <previous-commit-hash>
+
+# 2. 재빌드 및 배포
+docker-compose -f docker-compose-prod.yml up -d --build
+
+# 3. 검증 후 브랜치 업데이트 (필요시)
+# git checkout develop
+# git reset --hard <previous-commit-hash>
+# git push -f origin develop
+```
+
+---
+
+## 모니터링 및 헬스체크
+
+### 헬스체크 엔드포인트
+
+```bash
+# API 헬스체크
+curl http://localhost:8080/monitor/health
+curl http://localhost:8080/monitor/health/readiness
+curl http://localhost:8080/monitor/health/liveness
+
+# Nginx를 통한 헬스체크
+curl -k https://api.train-kamco.com/monitor/health
+```
+
+### 컨테이너 상태 모니터링
+
+```bash
+# 모든 컨테이너 상태
+docker ps -a | grep kamco
+
+# 리소스 사용량 실시간 모니터링
+docker stats kamco-train-nginx kamco-train-api
+
+# 헬스체크 상태
+docker inspect kamco-train-api | grep -A 10 Health
+```
+
+### 로그 모니터링
+
+```bash
+# 실시간 로그 (모든 서비스)
+docker-compose -f docker-compose-nginx.yml logs -f &
+docker-compose -f docker-compose-prod.yml logs -f &
+
+# 에러 로그만 필터링
+docker-compose -f docker-compose-prod.yml logs | grep -i error
+
+# 최근 100줄
+docker-compose -f docker-compose-prod.yml logs --tail=100
+```
+
+---
+
+## 트러블슈팅
+
+### 1. Nginx 502 Bad Gateway
+
+**원인**: API 서비스가 준비되지 않음
+
+```bash
+# API 컨테이너 상태 확인
+docker ps | grep kamco-train-api
+
+# API 로그 확인
+docker logs kamco-train-api --tail=100
+
+# 네트워크 연결 확인
+docker network inspect kamco-cds | grep kamco-train-api
+
+# 해결: API 재시작
+docker-compose -f docker-compose-prod.yml restart
+```
+
+### 2. SSL 인증서 오류
+
+**원인**: 인증서 파일 누락 또는 권한 문제
+
+```bash
+# 인증서 파일 확인
+ls -la nginx/ssl/
+
+# Nginx 설정 검증
+docker exec kamco-train-nginx nginx -t
+
+# 해결: 인증서 재배치 및 권한 설정
+chmod 600 nginx/ssl/train-kamco.com.key
+chmod 644 nginx/ssl/train-kamco.com.crt
+docker-compose -f docker-compose-nginx.yml restart
+```
+
+### 3. 컨테이너 시작 실패
+
+**원인**: 포트 충돌, 볼륨 권한, 메모리 부족
+
+```bash
+# 포트 사용 확인
+netstat -tulpn | grep -E '80|443|8080'
+
+# 볼륨 권한 확인
+ls -la ./app/
+
+# 메모리 사용량 확인
+free -h
+docker system df
+
+# 해결: 충돌 프로세스 종료 또는 포트 변경
+# 메모리 정리
+docker system prune -a
+```
+
+### 4. 네트워크 연결 문제
+
+**원인**: kamco-cds 네트워크 미생성 또는 컨테이너 미연결
+
+```bash
+# 네트워크 확인
+docker network ls | grep kamco-cds
+
+# 네트워크 상세 정보
+docker network inspect kamco-cds
+
+# 해결: 네트워크 생성
+docker network create kamco-cds
+
+# 컨테이너를 네트워크에 연결
+docker network connect kamco-cds kamco-train-api
+docker network connect kamco-cds kamco-train-nginx
+```
+
+### 5. 데이터베이스 연결 실패
+
+**원인**: application-prod.yml의 DB 설정 오류
+
+```bash
+# API 로그에서 DB 연결 에러 확인
+docker logs kamco-train-api | grep -i "connection"
+
+# DB 호스트 연결 테스트
+docker exec kamco-train-api ping <db-host>
+
+# 해결: application-prod.yml 수정 후 재배포
+vim src/main/resources/application-prod.yml
+docker-compose -f docker-compose-prod.yml up -d --build
+```
+
+---
+
+## Jenkins CI/CD 연동
+
+현재 프로젝트는 Jenkins 파이프라인으로 자동 배포됩니다.
+
+### Jenkinsfile-dev 주요 단계

+# SSL 사설 인증서 설정 가이드 (RedHat 9.6)
+
+## 개요
+
+이 문서는 RedHat 9.6 환경에서 `https://api.train-kamco.com` 및 `https://train-kamco.com` 도메인을 위한 100년 유효한 사설 SSL 인증서 설정 방법을 설명합니다.
+
+## 디렉토리 구조
+
+```
+nginx/
+├── nginx.conf              # Nginx 설정 파일
+├── ssl/
+│   ├── openssl.cnf         # OpenSSL 설정 파일 (SAN 포함)
+│   ├── train-kamco.com.crt # 사설 SSL 인증서 (멀티 도메인)
+│   └── train-kamco.com.key # 개인 키 (비공개)
+└── SSL_SETUP.md            # 이 문서
+```
+
+## 인증서 정보
+
+- **도메인**: api.train-kamco.com, train-kamco.com (멀티 도메인)
+- **유효 기간**: 100년 (36500일)
+- **알고리즘**: RSA 4096-bit
+- **CN (Common Name)**: api.train-kamco.com
+- **SAN (Subject Alternative Names)**: api.train-kamco.com, train-kamco.com
+
+## 사설 SSL 인증서 생성 (이미 생성됨)
+
+인증서가 이미 생성되어 있습니다. 재생성이 필요한 경우 아래 단계를 따르세요.
+
+### 1. OpenSSL 설정 파일 생성
+
+```bash
+cd /path/to/kamco-train-api
+
+cat > nginx/ssl/openssl.cnf << 'EOF'
+[req]
+default_bits = 4096
+prompt = no
+default_md = sha256
+distinguished_name = dn
+req_extensions = v3_req
+
+[dn]
+C=KR
+ST=Seoul
+L=Seoul
+O=KAMCO
+OU=Training
+CN=api.train-kamco.com
+
+[v3_req]
+subjectAltName = @alt_names
+
+[alt_names]
+DNS.1 = api.train-kamco.com
+DNS.2 = train-kamco.com
+EOF
+```
+
+### 2. SSL 인증서 및 개인 키 생성
+
+```bash
+# nginx/ssl 디렉토리 생성 (없는 경우)
+mkdir -p nginx/ssl
+chmod 700 nginx/ssl
+
+# 인증서 및 개인 키 생성 (100년 유효)
+openssl req -new -x509 -newkey rsa:4096 -sha256 -nodes \
+  -keyout nginx/ssl/train-kamco.com.key \
+  -out nginx/ssl/train-kamco.com.crt \
+  -days 36500 \
+  -config nginx/ssl/openssl.cnf \
+  -extensions v3_req
+
+# 파일 권한 설정
+chmod 600 nginx/ssl/train-kamco.com.key
+chmod 644 nginx/ssl/train-kamco.com.crt
+```
+
+### 3. 인증서 검증
+
+```bash
+# 인증서 정보 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -text -noout
+
+# 유효 기간 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -text -noout | grep -A2 "Validity"
+
+# SAN (멀티 도메인) 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -text -noout | grep -A1 "Subject Alternative Name"
+
+# CN 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -noout -subject
+
+# 개인 키 확인
+openssl rsa -in nginx/ssl/train-kamco.com.key -check
+```
+
+**예상 결과**:
+```
+X509v3 Subject Alternative Name:
+    DNS:api.train-kamco.com, DNS:train-kamco.com
+
+Validity
+    Not Before: Mar  2 23:39:XX 2026 GMT
+    Not After : Feb  6 23:39:XX 2126 GMT
+```
+
+## /etc/hosts 설정 (RedHat 9.6)
+
+### 1. hosts 파일에 도메인 추가
+
+```bash
+# root 권한으로 실행
+echo "127.0.0.1   api.train-kamco.com train-kamco.com" | sudo tee -a /etc/hosts
+
+# 확인
+cat /etc/hosts | grep train-kamco
+```
+
+**예상 결과**:
+```
+127.0.0.1   api.train-kamco.com train-kamco.com
+```
+
+### 2. 도메인 확인
+
+```bash
+# ping 테스트
+ping -c 2 api.train-kamco.com
+ping -c 2 train-kamco.com
+```
+
+## Docker Compose 배포
+
+### 1. 기존 컨테이너 중지 (실행 중인 경우)
+
+```bash
+cd /path/to/kamco-train-api
+docker-compose -f docker-compose-prod.yml down
+```
+
+### 2. Production 환경 실행
+
+```bash
+# IMAGE_TAG 환경 변수 설정 (선택사항)
+export IMAGE_TAG=latest
+
+# Docker Compose 실행
+docker-compose -f docker-compose-prod.yml up -d
+
+# 컨테이너 상태 확인
+docker-compose -f docker-compose-prod.yml ps
+```
+
+### 3. 로그 확인
+
+```bash
+# Nginx 로그
+docker logs kamco-cd-nginx
+
+# API 로그
+docker logs kamco-cd-training-api
+
+# 실시간 로그 확인
+docker-compose -f docker-compose-prod.yml logs -f
+```
+
+## HTTPS 접속 테스트
+
+### 1. HTTP → HTTPS 리다이렉트 테스트
+
+```bash
+# api.train-kamco.com
+curl -I http://api.train-kamco.com
+
+# train-kamco.com
+curl -I http://train-kamco.com
+
+# 예상 결과: 301 Moved Permanently
+# Location: https://api.train-kamco.com/ 또는 https://train-kamco.com/
+```
+
+### 2. HTTPS 헬스체크 (-k: 사설 인증서 경고 무시)
+
+```bash
+# api.train-kamco.com
+curl -k https://api.train-kamco.com/monitor/health
+
+# train-kamco.com
+curl -k https://train-kamco.com/monitor/health
+
+# 예상 결과: {"status":"UP","components":{...}}
+```
+
+### 3. SSL 인증서 확인
+
+```bash
+# api.train-kamco.com
+openssl s_client -connect api.train-kamco.com:443 -showcerts
+
+# train-kamco.com
+openssl s_client -connect train-kamco.com:443 -showcerts
+
+# CN 및 SAN 확인
+```
+
+### 4. 브라우저 테스트
+
+브라우저에서 다음 URL에 접속:
+
+- `https://api.train-kamco.com/monitor/health`
+- `https://train-kamco.com/monitor/health`
+
+**주의**: 사설 인증서이므로 "안전하지 않음" 경고가 표시됩니다.
+- **Chrome/Edge**: "고급" → "계속 진행" 클릭
+- **Firefox**: "위험 감수 및 계속" 클릭
+
+## 브라우저에서 사설 인증서 신뢰 설정 (선택사항)
+
+사설 인증서를 브라우저에 등록하면 경고 없이 접속 가능합니다.
+
+### Chrome/Edge (RedHat Desktop)
+
+1. `chrome://settings/certificates` 접속
+2. **Authorities** 탭 선택
+3. **Import** 클릭
+4. `nginx/ssl/train-kamco.com.crt` 선택
+5. **Trust this certificate for identifying websites** 체크
+6. **OK** 클릭
+
+### Firefox
+
+1. `about:preferences#privacy` 접속
+2. **Certificates** → **View Certificates** 클릭
+3. **Authorities** 탭 선택
+4. **Import** 클릭
+5. `nginx/ssl/train-kamco.com.crt` 선택
+6. **Trust this CA to identify websites** 체크
+7. **OK** 클릭
+
+## 방화벽 설정 (RedHat 9.6)
+
+### 1. 방화벽 상태 확인
+
+```bash
+sudo firewall-cmd --state
+```
+
+### 2. HTTP (80) 및 HTTPS (443) 포트 개방
+
+```bash
+# HTTP 포트 개방
+sudo firewall-cmd --permanent --add-port=80/tcp
+
+# HTTPS 포트 개방
+sudo firewall-cmd --permanent --add-port=443/tcp
+
+# 방화벽 재로드
+sudo firewall-cmd --reload
+
+# 확인
+sudo firewall-cmd --list-ports
+```
+
+**예상 결과**:
+```
+80/tcp 443/tcp
+```
+
+## 보안 체크리스트
+
+- [x] `train-kamco.com.key` 파일 권한이 600으로 설정됨
+- [x] ssl 디렉토리가 버전 관리에서 제외됨 (.gitignore 확인)
+- [x] 두 도메인(api.train-kamco.com, train-kamco.com) 모두 SAN에 포함됨
+- [ ] 방화벽에서 80, 443 포트 개방 확인
+- [x] HSTS 헤더 활성화 확인
+- [x] TLS 1.2 이상만 허용 확인
+- [ ] /etc/hosts에 도메인 매핑 확인
+
+## 트러블슈팅
+
+### 인증서 관련 오류
+
+**"certificate verify failed"**
+```bash
+# 해결: -k 플래그 사용 (사설 인증서 경고 무시)
+curl -k https://api.train-kamco.com/monitor/health
+```
+
+**"NET::ERR_CERT_AUTHORITY_INVALID" (브라우저)**
+- 정상 동작: 사설 인증서이므로 브라우저 경고는 예상된 동작입니다
+- 해결: 브라우저에 인증서 등록 (위 "브라우저에서 사설 인증서 신뢰 설정" 참조)
+
+### 연결 오류
+
+**"Connection refused"**
+```bash
+# 컨테이너 상태 확인
+docker ps | grep kamco-cd
+
+# 포트 바인딩 확인
+docker port kamco-cd-nginx
+
+# 예상 결과:
+# 80/tcp -> 0.0.0.0:80
+# 443/tcp -> 0.0.0.0:443
+```
+
+**"502 Bad Gateway"**
+```bash
+# API 컨테이너 상태 확인
+docker logs kamco-cd-training-api
+
+# nginx → API 연결 확인
+docker exec kamco-cd-nginx wget -qO- http://kamco-changedetection-api:8080/monitor/health
+```
+
+**"Name or service not known" (도메인 해석 실패)**
+```bash
+# /etc/hosts 확인
+cat /etc/hosts | grep train-kamco
+
+# 없으면 추가
+echo "127.0.0.1   api.train-kamco.com train-kamco.com" | sudo tee -a /etc/hosts
+```
+
+### 방화벽 관련 오류
+
+**외부에서 접속 안 됨**
+```bash
+# 방화벽 확인
+sudo firewall-cmd --list-ports
+
+# 포트 개방
+sudo firewall-cmd --permanent --add-port=80/tcp
+sudo firewall-cmd --permanent --add-port=443/tcp
+sudo firewall-cmd --reload
+```
+
+## 인증서 만료 및 갱신
+
+### 만료 확인
+
+```bash
+# 인증서 만료일 확인
+openssl x509 -in nginx/ssl/train-kamco.com.crt -noout -enddate
+
+# 예상 결과: notAfter=Feb  6 23:39:XX 2126 GMT (100년 후)
+```
+
+### 갱신 방법 (필요시)
+
+100년 유효한 인증서이므로 갱신이 필요하지 않지만, 재생성이 필요한 경우:
+
+```bash
+# 기존 인증서 백업
+cp nginx/ssl/train-kamco.com.crt nginx/ssl/train-kamco.com.crt.bak
+cp nginx/ssl/train-kamco.com.key nginx/ssl/train-kamco.com.key.bak
+
+# 위의 "사설 SSL 인증서 생성" 단계 재실행
+
+# nginx 재시작
+docker-compose -f docker-compose-prod.yml restart nginx
+```
+
+## 주의사항
+
+1. **사설 인증서 경고**: 브라우저에서 "안전하지 않음" 경고가 표시됩니다. 프로덕션 환경에서는 **공인 인증서(Let's Encrypt, GlobalSign 등) 사용을 권장**합니다.
+
+2. **포트 80/443**: Docker가 자동으로 처리하지만, 이미 사용 중인 프로세스가 있으면 충돌할 수 있습니다.
+   ```bash
+   # 포트 사용 확인
+   sudo lsof -i :80
+   sudo lsof -i :443
+   ```
+
+3. **대용량 파일 업로드**: `client_max_body_size`를 10GB로 설정했으므로, 서버 메모리 및 디스크 용량을 충분히 확보하세요.
+
+4. **인증서 백업**: `train-kamco.com.key` 파일은 매우 중요합니다. 안전한 곳에 백업하세요.
+
+5. **SELinux**: RedHat 9.6에서 SELinux가 활성화된 경우, Docker 볼륨 마운트 권한 문제가 발생할 수 있습니다.
+   ```bash
+   # SELinux 상태 확인
+   getenforce
+
+   # 필요시 permissive 모드로 변경
+   sudo setenforce 0
+   ```
+
+
+### 2단계: 시스템 신뢰 폴더로 복사
+터미널을 열고 관리자 권한(sudo)을 사용해 인증서를 시스템 폴더로 복사합니다.
+
+```
+sudo cp mycert.crt /etc/pki/ca-trust/source/anchors/
+```
+
+### 3단계: 시스템 신뢰 목록 업데이트
+아래 명령어를 입력해 추가한 인증서를 시스템에 갱신시킵니다.
+
+```
+sudo update-ca-trust
+```
