## 启动项目（本地）
|
|
|
|
|
|
|
|
|
|
|
|
1. 准备环境
|
|
|
|
|
|
- 推荐 Python 3.11+
|
|
|
|
|
|
- 创建并激活虚拟环境：`python3 -m venv .venv && source .venv/bin/activate`
|
|
|
|
|
|
- 依赖安装：`pip install -r requirements.txt`（若 requirements.txt 为 UTF-16，需要先转 UTF-8）
|
|
|
|
|
|
|
|
|
|
|
|
2. 配置数据库
|
|
|
|
|
|
- 确保本地 MySQL 运行，并创建数据库/账号（例）：
|
|
|
|
|
|
```sql
|
|
|
|
|
|
CREATE DATABASE allm DEFAULT CHARACTER SET utf8mb4;
|
2026-01-21 13:59:02 +08:00
|
|
|
|
ALTER USER 'root'@'localhost' IDENTIFIED BY '*******';
|
2026-01-21 13:43:18 +08:00
|
|
|
|
GRANT ALL PRIVILEGES ON allm.* TO 'root'@'localhost';
|
|
|
|
|
|
FLUSH PRIVILEGES;
|
|
|
|
|
|
```
|
|
|
|
|
|
- 启动前设置环境变量：
|
|
|
|
|
|
```bash
|
2026-01-21 13:59:02 +08:00
|
|
|
|
export DATABASE_URL="******"
|
2026-01-21 13:43:18 +08:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
3. 迁移（首次必跑）
|
|
|
|
|
|
```bash
|
|
|
|
|
|
python -m alembic upgrade head
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
4. 启动服务
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# 启动项目命令
|
|
|
|
|
|
python3 -m uvicorn main:app --host 0.0.0.0 --port 8000 --reload
|
|
|
|
|
|
```
|
