Redis Server 安裝
Redis Python 套件 (redis==5.0.1) 僅為客戶端,需另外安裝 Redis Server:
macOS (Homebrew):
brew install redis
brew services start redis
Ubuntu/Debian:
sudo apt update
sudo apt install redis-server
sudo systemctl start redis-server
sudo systemctl enable redis-server
Docker:
docker run -d --name redis -p 6379:6379 redis:alpine
驗證安裝:
redis-cli ping
# 應回傳 PONG
環境建置
# 使用 Conda
conda env create -f environment.yml
conda activate pjctrl
# 或使用 pip
pip install -r requirements.txt
設定
複製並編輯環境變數:
cp .env.example .env
主要設定項目:
MYSQL_*- 資料庫連線REDIS_*- Redis 連線JWT_SECRET_KEY- JWT 簽名密鑰 (生產環境必須更換)AUTH_API_URL- 外部認證 API
執行
# 開發模式
uvicorn app.main:app --reload --port 8000
# 生產模式
uvicorn app.main:app --host 0.0.0.0 --port 8000
資料庫遷移
# 升級至最新版本
alembic upgrade head
# 回滾一個版本
alembic downgrade -1
測試
pytest -v
