+# ⛔ CRITICAL: 배포 전 필수 확인사항 (DO NOT SKIP!)
+
+## 🚨 Production 환경 고정값 (절대 변경 금지!)
+
+| 항목 | 올바른 값 | 잘못된 예 |
+|------|----------|----------|
+| **DB_NAME** | `autonet` | ~~mongolcar~~, ~~autonet_db~~ |
+| **DB_PASSWORD** | `roskfl@1122` (@ 포함, URL 인코딩 필요) | - |
+| **API_URL (Frontend)** | `https://autonetsellcar.com` | ~~http://192.168.0.202:8000~~ |

+| **배포 디렉토리** | `/opt/autonet/production` | ~~`/home/damon/mongolcar`~~ |
+
+## 🚫 절대 하지 말 것
+
+1. **수동 `docker run`에서 환경변수 직접 타이핑 금지** - [PRODUCTION_VALUES.md](./PRODUCTION_VALUES.md)에서 복사만 허용
+2. **DB_NAME 직접 타이핑 금지** - 반드시 `autonet` 복사/붙여넣기
+3. **`.env` 파일 덮어쓰기 금지** - 서버의 기존 `.env` 보존
+4. **`/home/damon/mongolcar/data/uploads` 사용 금지** - 비어있는 잘못된 경로
+
+## ✅ 배포 전 필수 검증 명령어
+
+```bash
+# 1. DB 이름 확인 (반드시 autonet이어야 함!)
+ssh server1 "docker exec postgres-primary psql -U admin -d autonet -c 'SELECT COUNT(*) FROM cars;'"
+
+# 2. Uploads 경로에 파일 있는지 확인
+ssh server2 "ls /opt/autonet/production/backend/uploads/cars/ | head -5"

+# 3. 배포 후 API 확인

+
+## 2026-01-02: 반복되는 배포 오류 종합 (CRITICAL)
+
+### 문제 1: DB_NAME 오류 (`mongolcar` vs `autonet`)
+
+**증상**:
+- 사이트에 차량/배너 없음
+- API가 빈 배열 `[]` 반환
+- 로그인은 되지만 데이터 없음
+
+**원인**:
+- 수동 `docker run` 시 DB_NAME을 `mongolcar`로 잘못 입력
+- PostgreSQL에 `mongolcar`와 `autonet` 두 DB가 존재
+- `mongolcar`는 비어있고, 실제 데이터는 `autonet`에 있음
+
+**확인 방법**:
+```bash
+# 현재 연결된 DB 확인
+ssh server2 "docker exec autonet-backend python -c \"from app.config import get_settings; print('DB_NAME:', get_settings().DB_NAME)\""
+
+# DB별 데이터 확인
+ssh server1 "docker exec postgres-primary psql -U admin -d autonet -c 'SELECT COUNT(*) FROM cars;'"
+ssh server1 "docker exec postgres-primary psql -U admin -d mongolcar -c 'SELECT COUNT(*) FROM cars;'"
+```
+
+**해결**:
+- `DB_NAME=autonet` 확인 후 컨테이너 재시작
+- CLAUDE.md의 표준 명령어 복사해서 사용
+
+---
+
+### 문제 2: 비밀번호 `@` 파싱 오류
+
+**증상**:
+- `could not translate host name "1122@192.168.0.201"`
+- 백엔드 컨테이너 계속 재시작
+
+**원인**:
+- `DB_PASSWORD=roskfl@1122`의 `@`가 URL에서 호스트 구분자로 인식됨
+- `config.py`에 `quote_plus()` URL 인코딩이 없거나, Docker 이미지가 오래됨
+
+**확인 방법**:
+```bash
+# config.py에 quote_plus 있는지 확인
+ssh server2 "docker exec autonet-backend cat /app/app/config.py | grep quote_plus"
+```
+
+**해결**:
+1. `config.py`에 `quote_plus()` 적용 확인
+2. Docker 이미지 재빌드: `docker build --no-cache -t production-backend ./backend`
+
+---
+
+### 문제 3: 이미지 404 (잘못된 uploads 경로)
+
+**증상**:
+- `/uploads/cars/40/image_0.jpg` → 404
+- Hero 배너에 기본 이미지만 표시
+
+**원인**:
+- Production 컨테이너가 잘못된 경로 마운트: `/home/damon/mongolcar/data/uploads` (비어있음!)
+- 실제 이미지는 `/opt/autonet/production/backend/uploads`에 있음
+
+**확인 방법**:
+```bash
+# 올바른 경로 (파일 있어야 함)
+ssh server2 "ls /opt/autonet/production/backend/uploads/cars/ | head -5"
+
+# 잘못된 경로 (비어있음!)
+ssh server2 "ls /home/damon/mongolcar/data/uploads/cars/ 2>/dev/null || echo 'Empty or not exists'"
+```
+
+**해결**:
+- 볼륨 마운트를 `-v /opt/autonet/production/backend/uploads:/app/uploads`로 변경
+- CLAUDE.md의 표준 명령어 사용
+
+---
+
+### 문제 4: Mixed Content (HTTPS/HTTP)
+
+**증상**:
+- 브라우저 콘솔에 Mixed Content 오류
+- API 요청 실패
+- 사이트에 기본 이미지만 표시
+
+**원인**:
+- Frontend가 `NEXT_PUBLIC_API_URL=http://192.168.0.202:8000`으로 빌드됨
+- HTTPS 페이지에서 HTTP API 호출 시 브라우저가 차단
+
+**확인 방법**:
+```bash
+# 빌드된 JS에서 API URL 확인
+ssh server2 "docker exec autonet-frontend grep -r '192.168.0.202:8000' /app/.next/static/chunks/ | head -1"
+```
+
+**해결**:
+```bash
+# Frontend 빌드 전 필수!
+ssh server2 "echo 'NEXT_PUBLIC_API_URL=https://autonetsellcar.com' > /home/damon/mongolcar/frontend/.env.production"
+ssh server2 "cd /home/damon/mongolcar/frontend && docker build --no-cache -t production-frontend ."
+```
+
+---
+
+### 문제 5: .env 파일이 디렉토리로 생성됨
+
+**증상**:
+- 로그인 실패
+- `(sqlite3.OperationalError) no such column` 에러
+- 환경변수 로드 실패
+
+**원인**:
+- docker-compose 볼륨 마운트 시 `.env` 파일이 없으면 디렉토리로 생성됨
+
+**확인 방법**:
+```bash
+ssh server2 "ls -la /opt/autonet/production/backend/.env"
+# 'd'로 시작하면 디렉토리 (문제!)
+```
+
+**해결**:
+```bash
+# 디렉토리면 삭제 후 파일로 재생성
+ssh server2 "rm -rf /opt/autonet/production/backend/.env"
+ssh server2 "cat > /opt/autonet/production/backend/.env << 'EOF'
+USE_SQLITE=False
+DB_HOST=192.168.0.201
+DB_PORT=5432
+DB_NAME=autonet
+DB_USER=admin
+DB_PASSWORD=roskfl@1122
+EOF"
+```
+
+---
+
+## 재발 방지 체크리스트
+
+배포 시 반드시 확인:
+
+- [ ] DB_NAME이 `autonet`인가? (절대 `mongolcar` 아님!)
+- [ ] Uploads 경로가 `/opt/autonet/production/backend/uploads`인가?
+- [ ] Frontend `.env.production`에 `https://autonetsellcar.com`이 설정되어 있는가?
+- [ ] `--no-cache`로 이미지를 빌드했는가?
+- [ ] 배포 후 `curl https://autonetsellcar.com/api/hero-banners/`로 데이터 확인했는가?
