以下是基于宝塔面板部署AI工作流引擎网站的详细教程和文件结构说明:
一、文件结构清单
/root/ai-workflow-engine/ ├── app/ # 主应用目录 │ ├── __init__.py │ ├── routes/ # 路由模块 │ │ ├── project_routes.py │ │ └── task_routes.py │ ├── models/ # 数据库模型 │ │ ├── project.py │ │ └── task.py │ ├── services/ # 业务服务 │ │ ├── workflow_engine.py │ │ ├── file_manager.py │ │ └── ai_clients.py │ ├── tasks/ # Celery任务 │ │ ├── __init__.py │ │ └── workflow_tasks.py │ └── utils/ # 工具类 │ ├── security.py │ └── file_utils.py ├── config.py # 主配置文件 ├── requirements.txt # 依赖清单 ├── start.sh # 启动脚本 ├── celery_worker.py # Celery工作进程 ├── static/ # 静态资源 │ ├── css/ │ ├── js/ │ └── images/ └── templates/ # 网页模板 ├── dashboard.html └── project_detail.html
二、宝塔面板部署教程
第一步:服务器准备
购买云服务器(推荐2核4G以上配置)
安装宝塔面板(官方安装命令)
登录宝塔面板完成初始化设置
第二步:环境安装
软件商店安装:
Nginx 1.22+
MySQL 8.0+
Redis 7.0+
Python项目管理器 2.0+
终端执行:
# 安装系统依赖apt-get install python3-dev libpq-dev redis-server -y
第三步:创建Python项目
打开「Python项目管理器」
新建项目:
项目路径:
/www/wwwroot/ai-workflow
Python版本:3.9+
框架选择:Flask
勾选「安装项目依赖」
端口号:5000
上传项目文件到项目目录
第四步:数据库配置
创建MySQL数据库:
数据库名:
ai_workflow
用户名:
workflow_user
密码:
StrongPassword123!
修改数据库配置(config.py):
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://workflow_user:StrongPassword123!@localhost/ai_workflow'
第五步:环境变量配置
在项目根目录创建
.env
文件:
DEEPSEEK_API_KEY=your_api_keyCELERY_BROKER_URL=redis://localhost:6379/0FILE_STORAGE_PATH=/www/ai_workflow_data
在宝塔面板「Python项目管理器」添加环境变量:
FLASK_APP=app FLASK_ENV=production
第六步:依赖安装
在项目终端执行:
pip install -r requirements.txt
关键依赖说明:
flask==3.0.2 celery==5.3.6 sqlalchemy==2.0.28 redis==5.0.3 python-dotenv==1.0.1
第七步:进程守护配置
配置Flask主进程:
名称:
AI-Workflow
启动命令:
flask run --host=0.0.0.0 --port=5000
运行目录:
/www/wwwroot/ai-workflow
配置Celery Worker:
名称:
Celery-Worker
启动命令:
celery -A app.tasks.workflow_tasks worker --loglevel=info
运行目录:
/www/wwwroot/ai-workflow
第八步:Nginx反向代理
添加站点:
域名:
workflow.yourdomain.com
根目录:
/www/wwwroot/ai-workflow/static
配置反向代理:
location / { proxy_pass http://127.0.0.1:5000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}
配置SSL证书(推荐使用Let's Encrypt)
第九步:文件存储配置
创建数据存储目录:
mkdir -p /www/ai_workflow_datachmod 755 /www/ai_workflow_data
修改文件管理器配置(file_manager.py):
FILE_BASE_PATH = os.getenv('FILE_STORAGE_PATH', '/www/ai_workflow_data')
第十步:初始化数据库
进入Python终端:
flask shell
执行数据库初始化:
from app import db db.create_all()
三、安全加固建议
防火墙设置:
仅开放80/443端口
禁用SSH密码登录
数据库安全:
限制MySQL仅本地访问
定期备份数据库
文件权限:
chown -R www:www /www/ai_workflow_datachmod 750 /www/ai_workflow_data
速率限制(Nginx配置):
limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;location /api/ { limit_req zone=api_limit burst=20; proxy_pass http://127.0.0.1:5000;}
四、系统验证
访问测试:
打开
https://workflow.yourdomain.com/create
提交测试项目查看
/status/<project_id>
接口验证进度更新
文件生成检查:
ls -l /www/ai_workflow_data/project_123# 应看到 structure.json 和 project_123.zip
Celery状态监控:
celery -A app.tasks.workflow_tasks status
该方案采用生产级部署架构,支持以下特性:
多用户隔离:通过数据库关联用户与项目
负载均衡:可扩展多个Celery Worker
自动清理:建议添加定时任务清理7天前的临时文件
实时监控:集成宝塔面板的实时资源监控
可根据实际需求调整配置参数,建议使用前进行压力测试和安全性评估。

文件说明和使用方法:
数据库初始化:
flask shell>>> from app import db>>> db.create_all()
启动服务:
# 启动Flask应用./start.sh# 启动Celery Worker(新终端)celery -A app.tasks.workflow_tasks worker --loglevel=info
API调用示例:
# 创建项目curl -X POST -H "Content-Type: application/json" -d '{"name":"电商系统"}' http://localhost:5000/api/projects/create# 查看状态curl http://localhost:5000/api/projects/status/<project_id>
以上代码实现了完整的AI工作流引擎核心功能,可根据实际需求扩展以下模块:
用户认证:在security.py中添加JWT认证
文件清理:在file_manager.py中添加定期清理任务
通知系统:集成邮件/Webhook通知功能
日志监控:添加ELK日志收集和分析
负载均衡:使用Redis作为Celery结果后端
建议在生产环境配置Nginx反向代理和HTTPS加密,并通过宝塔面板进行服务监控和维护。
以下是完整的数据库建表SQL语句,包含表结构、字段约束和关系定义:

表结构说明:
projects表:
id
: UUID主键(由应用层生成)name
: 项目名称(最大128字符)status
: 项目状态枚举值created_at
: 精确到秒的创建时间output_path
: 项目文件存储绝对路径
tasks表:
id
: 自增主键project_id
: 外键关联projects表step
: 步骤序号(1-255)status
: 任务状态枚举值result
: 存储任务执行结果(如生成的文件路径)自动维护的
created_at
和updated_at
时间戳
users表(扩展功能):
用户身份验证基础表
包含用户名、邮箱和密码哈希
project_users表:
项目与用户的权限关系表
定义用户对项目的访问级别
数据库初始化建议步骤:
通过宝塔面板创建数据库:
# 登录MySQL(宝塔安装的MySQL可能使用不同socket路径)mysql -u root -p# 执行建表SQLsource /path/to/create_tables.sql
验证表结构:
SHOW TABLES;DESC projects;DESC tasks;
添加测试数据示例:
INSERT INTO projects (id, name, status, created_at, output_path)VALUES ('550e8400-e29b-41d4-a716-446655440000', '测试项目', 'PENDING', NOW(), '/data/projects/550e8400');INSERT INTO tasks (project_id, step, description, status)VALUES ('550e8400-e29b-41d4-a716-446655440000', 1, '生成项目结构', 'PENDING'), ('550e8400-e29b-41d4-a716-446655440000', 2, '生成代码文件', 'PENDING'), ('550e8400-e29b-41d4-a716-446655440000', 3, '打包项目', 'PENDING');
注意事项:
字符集设置:
使用
utf8mb4
字符集支持emoji和全部Unicode字符排序规则使用
utf8mb4_unicode_ci
以获得准确的排序结果
外键约束:
确保使用InnoDB引擎以支持外键
ON DELETE CASCADE
保证删除项目时自动删除相关任务
索引优化:
项目表:在status和created_at字段建立索引
任务表:建立组合索引(step, status)提升查询效率
字段注释:
所有字段均添加COMMENT说明,方便后续维护
扩展性设计:
users表和project_users表为多用户支持预留
output_path字段长度256字符以适应长路径存储
实际部署时请根据服务器配置调整存储路径和权限设置,建议定期执行OPTIMIZE TABLE
维护数据库性能。
