Accessing Node-RED

브라우저를 열고 다음 주소를 방문하세요: https://<SERVER_IP>
브라우저에서 SSL 경고가 표시될 수 있습니다(자체 서명 인증서).
인증が必要です (기본 인증 팝업)
인증 방식: HTTP 기본 인증
인증 정보는 다음 위치에 안전하게 저장됩니다: /root/.cloudzy-creds

중요한 파일 및 디렉터리

Main installation directory is /root/node-red.
Docker orchestration file is /root/node-red/docker-compose.yml.
Persistent Node-RED data is stored in /var/lib/docker/volumes/node-red_node-red-data/_data.
Nginx configuration file is located at /etc/nginx/sites-available/node-red.
Basic authentication credentials are stored in /etc/nginx/auth/node-red.htpasswd.
TLS certificates are stored in /etc/nginx/ssl.

서비스 관리

컨테이너 상태 확인:

docker ps

로그 보기:

docker compose -f /root/node-red/docker-compose.yml logs -f

Restart Node-RED:

docker compose -f /root/node-red/docker-compose.yml restart

Nginx 재시작:

systemctl restart nginx

Node-RED Admin User (Alternative to Basic Auth)

Node-RED has its own internal authentication system, which can replace HTTP Basic Auth.

1. Locate `settings.js`

The main configuration file is inside the Node-RED Docker volume: /var/lib/docker/volumes/node-red_node-red-data/_data/settings.js

2. Enable `adminAuth`

열기 settings.js and uncomment (or add) the adminAuth section. It should look something like this:

  adminAuth: {
      type: "credentials",
      users: [
          {
              username: "admin",
              password: "<HASHED_PASSWORD>",
              permissions: "*"
      }]
  },

3. Generate a password hash

You can generate the hash from inside the Node-RED container:

docker exec -it node-red-node-red-1 node-red admin hash-pw

You will be prompted to enter your plain password.

Copy the resulting hash and paste it as the password value in settings.js.

4. Restart Node-RED

After editing settings.js:

docker compose -f /root/node-red/docker-compose.yml restart

5. Disable HTTP Basic Auth in Nginx (Optional)

Edit the Nginx site file: /etc/nginx/sites-available/node-red

Remove or comment out these lines:

auth_basic "Restricted";
auth_basic_user_file /etc/nginx/auth/node-red.htpasswd;

Nginx 재시작:

systemctl restart nginx

도메인에 SSL 활성화하기

1. 도메인을 서버 IP로 연결하십시오.

2. Nginx 설정을 편집하고 둘 다 교체하십시오. server_name <IP>; 귀하의 도메인과 함께 (<your-domain>HTTP(포트 80) 및 HTTPS(포트 443) 블록 모두에 대해:

vim /etc/nginx/sites-available/node-red

3. Certbot 설치:

apt install -y certbot python3-certbot-nginx

4. 유효한 Let’s Encrypt 인증서를 생성하려면 다음 명령어를 실행하십시오:

certbot certonly --nginx --non-interactive --agree-tos --email [email protected] -d yourdomain.com

5. Nginx 구성에서 SSL 경로 교체:

vim /etc/apache2/sites-available/node-red
# Before:
    # ssl_certificate /etc/nginx/ssl/fullchain.pem;
    # ssl_certificate_key /etc/nginx/ssl/privkey.pem;
# After:
    # ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    # ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;

6. 변경 사항을 적용하려면 Nginx를 재시작하십시오:

systemctl restart nginx

7. 브라우저를 열고 다음 주소를 방문하세요: https://yourdomain.com
