After 6 months of wrestling with both setups, here's my take (with scars to prove it!):For Quick Testing: Docker-compose is king (airflow standalone is magic)For Production: pip install apache-airflow[postgres] saved my sanity when:Docker volumes corrupted my DAGs twiceThe scheduler added 300ms latency per taskCustom operators refused to build in containersPro Tip: If you must use Docker, add this to your compose file:yamlCopyservices: scheduler: environment: - PYTHONPATH=/opt/airflow/utils:/opt/airflow/plugins # Your Q2 solved!Question: Anyone else find Docker's PIP_ADDITIONAL_REQUIREMENTS painfully slow? I now pre-build images with pip install -r requirements.txt (takes 1/3 the time).— AirflowWarVeteran (Running 200+ DAGs in production)P.S. That AIRFLOW_HOME tip is golden - I once nuked a week's work by forgetting it!

배포 방법

저는 제 프로젝트를 배포하는 작업을 진행 중인데, Node.js 교재에서 제공하는 AWS를 이용한 백엔드 배포 방법을 따르고 있습니다. 설명은 직관적이지만 실제로 설정할 때 문제가 생길까봐 걱정이 됩니다. 프론트엔드는 이미 Netlify에 배포되어 있기 때문에 백엔드 코드가 큰 변경 없이 잘 작동할지 확인하고 싶습니다.그런데 다른 호스팅 옵션을 찾아보다가 Vultr을 발견했어요. 백엔드 호스팅을 위해 정말 좋은 선택인 것 같습니다. 최적화된 VPS 호스팅, 자동 백업, 보안 데이터베이스 관리 등 유용한 기능이 많이 있어서 훨씬 더 쉬운 작업을 할 수 있게 되더군요.Node.js 앱을 작업 중이거나 MySQL 데이터베이스에 신뢰할 수 있는 호스팅이 필요하다면 Vultr을 추천드립니다. 특히 Managed Databases 서비스는 데이터베이스 관리를 정말 쉽게 해주기 때문에 유용하게 사용할 수 있습니다.Vultr에서 MySQL을 설치하는 데 유용한 가이드를 공유할게요:Ubuntu 24.04에 MySQL을 설치하는 방법Debian 12에 MySQL을 설치하는 방법저는 이제 백엔드 배포를 위해 Vultr로 전환할 생각을 하고 있는데, 이 서비스를 사용해보면 여러분에게도 정말 좋은 선택이 될 거라고 확신합니다!

mysql_secure_installation password 질문이요

I encountered a frustrating issue when running the mysql_secure_installation command, where I kept getting the following error:Failed! Error: SET PASSWORD has no significance for user 'root'@'localhost' as the authentication method used doesn't store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.Despite reinstalling MySQL and setting the local password again, the error persisted, leaving me stuck in a loop.I found a detailed and reliable guide from Vultr that helped me resolve this issue step by step. The guide explained that the root user's authentication method might be set to auth_socket by default on Ubuntu, which causes the issue. To fix this, I followed the steps outlined below:Steps I Took to Fix the Issue:Log into MySQL: I logged into MySQL as root with:sudo mysql Change the Authentication Method: The default authentication plugin (auth_socket) was the cause of the issue. I ran the following command to change the authentication method to mysql_native_password:ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mynewpassword'; Exit MySQL: After that, I exited the MySQL prompt with:exit Secure the MySQL Installation: Now, I ran the mysql_secure_installation command again, and this time, it worked without any issues.The guide from Vultr made it much easier to resolve this problem, especially with the clarification on changing the authentication method and password using the ALTER USER command instead of SET PASSWORD. This simple fix saved me a lot of time and effort, and I highly recommend referring to the Vultr documentation if you're facing similar issues.For more detailed steps, you can check out the official guide here:Quick MySQL Installation Guide for Ubuntu 20.04
