-# 云盘后端Linux打包指南
-
-## 概述
-
-本指南说明如何使用PyInstaller将云盘后端应用打包成Linux可执行文件，以便在没有Python环境的Linux服务器上部署运行。
-
-## 文件说明
-
-### 打包配置文件
-- `build.spec` - PyInstaller配置文件，定义了打包规则和依赖
-- `build_linux.py` - 完整的打包脚本，包含检查、清理、打包和部署包创建功能
-- `requirements-build.txt` - 打包所需的依赖包列表
-
-### 部署配置文件
-- `cloud-drive.service` - systemd服务配置文件
-- `install.sh` - 自动化安装脚本
-- `uninstall.sh` - 卸载脚本
-- `quick_build.sh` - 快速打包脚本
-
-## 环境要求
-
-### 开发环境（打包用）
-- Python 3.8+
-- PyInstaller 5.0+
-- 操作系统：Linux或Windows（交叉编译）
-
-### 目标环境（部署用）
-- Linux 64位系统
-- MySQL 5.7+ 或 8.0+
-- Redis (可选)
-- 至少512MB内存
-- 至少100MB磁盘空间
-
-## 打包步骤
-
-### 方法一：使用完整打包脚本
-
-```bash
-# 1. 进入后端目录
-cd backend
-
-# 2. 安装依赖
-pip install -r requirements.txt
-pip install pyinstaller
-
-# 3. 运行打包脚本
-python build_linux.py
-
-# 或者只清理构建目录
-python build_linux.py --clean
-```
-
-### 方法二：使用快速脚本
-
-```bash
-# 1. 进入后端目录
-cd backend
-
-# 2. 运行快速打包脚本
-chmod +x quick_build.sh
-./quick_build.sh
-```
-
-### 方法三：手动打包
-
-```bash
-# 1. 安装PyInstaller
-pip install pyinstaller
-
-# 2. 清理之前的构建
-rm -rf build dist __pycache__
-
-# 3. 执行打包
-pyinstaller --clean build.spec
-
-# 4. 创建部署包
-mkdir -p deploy/logs deploy/uploads
-cp dist/cloud-drive-server deploy/
-cp .env.example deploy/
-```
-
-## 打包输出
-
-成功打包后，会生成以下文件：
-
-```
-backend/
-├── deploy/                    # 部署包目录
-│   ├── cloud-drive-server    # 主程序可执行文件
-│   ├── start.sh              # 启动脚本
-│   ├── .env.example          # 环境配置示例
-│   ├── README.md             # 部署说明
-│   ├── logs/                 # 日志目录
-│   └── uploads/              # 上传文件目录
-├── build/                    # PyInstaller构建临时文件
-├── dist/                     # 打包输出目录
-└── build.spec               # 打包配置文件
-```
-
-## 部署到Linux服务器
-
-### 方法一：使用自动化安装脚本
-
-```bash
-# 1. 将整个deploy目录上传到服务器
-scp -r deploy/ user@server:/tmp/cloud-drive
-
-# 2. 在服务器上运行安装脚本（需要root权限）
-sudo /tmp/cloud-drive/install.sh
-```
-
-### 方法二：手动部署
-
-```bash
-# 1. 创建服务用户
-sudo useradd -r -s /bin/false cloud-drive
-
-# 2. 创建安装目录
-sudo mkdir -p /opt/cloud-drive/{logs,uploads}
-
-# 3. 复制文件
-sudo cp deploy/cloud-drive-server /opt/cloud-drive/
-sudo cp deploy/.env.example /opt/cloud-drive/
-sudo chmod +x /opt/cloud-drive/cloud-drive-server
-
-# 4. 设置权限
-sudo chown -R cloud-drive:cloud-drive /opt/cloud-drive
-
-# 5. 配置环境变量
-sudo cp /opt/cloud-drive/.env.example /opt/cloud-drive/.env
-sudo nano /opt/cloud-drive/.env  # 编辑配置
-
-# 6. 安装systemd服务
-sudo cp cloud-drive.service /etc/systemd/system/
-sudo systemctl daemon-reload
-sudo systemctl enable cloud-drive
-
-# 7. 启动服务
-sudo systemctl start cloud-drive
-```
-
-## 环境配置
-
-编辑 `/opt/cloud-drive/.env` 文件：
-
-```env
-# 数据库配置
-DATABASE_URL=mysql+pymysql://用户名:密码@主机:端口/数据库名
-
-# Redis配置
-REDIS_URL=redis://主机:端口
-
-# JWT配置
-JWT_SECRET_KEY=你的密钥
-JWT_EXPIRE_MINUTES=30
-
-# 运行环境
-ENVIRONMENT=production
-
-# 文件上传配置
-UPLOAD_DIR=uploads
-MAX_FILE_SIZE=10485760  # 10MB
-```
-
-## 服务管理
-
-```bash
-# 查看服务状态
-sudo systemctl status cloud-drive
-
-# 启动服务
-sudo systemctl start cloud-drive
-
-# 停止服务
-sudo systemctl stop cloud-drive
-
-# 重启服务
-sudo systemctl restart cloud-drive
-
-# 查看日志
-sudo journalctl -u cloud-drive -f
-
-# 查看应用日志
-tail -f /opt/cloud-drive/logs/app.log
-```
-
-## 验证部署
-
-```bash
-# 健康检查
-curl http://localhost:8000/api/v1/health
-
-# API文档
-curl http://localhost:8000/docs
-
-# 根路径
-curl http://localhost:8000/
-```
-
-## 故障排除
-
-### 1. 打包问题
-
-**问题**: `ImportError: No module named 'xxx'`
-**解决**: 在 `build.spec` 的 `hiddenimports` 列表中添加缺失的模块
-
-**问题**: 打包文件过大
-**解决**: 在 `build.spec` 的 `excludes` 列表中添加不需要的库
-
-### 2. 运行问题
-
-**问题**: 端口被占用
-```bash
-# 检查端口占用
-sudo netstat -tlnp | grep 8000
-# 或修改配置文件中的端口
-```
-
-**问题**: 数据库连接失败
-```bash
-# 检查数据库配置
-cat /opt/cloud-drive/.env
-# 测试连接
-mysql -h 主机 -u 用户 -p 数据库名
-```
-
-**问题**: 权限问题
-```bash
-# 检查文件权限
-ls -la /opt/cloud-drive/
-# 修复权限
-sudo chown -R cloud-drive:cloud-drive /opt/cloud-drive/
-```
-
-### 3. 性能优化
-
-**启用UPX压缩**（减小文件大小）：
-```bash
-# 安装UPX
-sudo apt install upx  # Ubuntu/Debian
-sudo yum install upx  # CentOS/RHEL
-
-# 在build.spec中确保 upx=True
-```
-
-**启用strip**（减小文件大小）：
-```bash
-# 在build.spec中确保 strip=True
-```
-
-## 更新和维护
-
-### 更新应用
-
-```bash
-# 1. 停止服务
-sudo systemctl stop cloud-drive
-
-# 2. 备份当前版本
-sudo cp /opt/cloud-drive/cloud-drive-server /opt/cloud-drive/cloud-drive-server.bak
-
-# 3. 替换新版本
-sudo cp new-cloud-drive-server /opt/cloud-drive/cloud-drive-server
-sudo chmod +x /opt/cloud-drive/cloud-drive-server
-
-# 4. 启动服务
-sudo systemctl start cloud-drive
-```
-
-### 日志管理
-
-日志会自动轮转（通过logrotate配置），也可以手动管理：
-
-```bash
-# 查看日志轮转配置
-cat /etc/logrotate.d/cloud-drive
-
-# 手动执行日志轮转
-sudo logrotate -f /etc/logrotate.d/cloud-drive
-```
-
-### 监控
-
-可以使用以下工具监控服务：
-
-```bash
-# systemd监控
-sudo systemctl status cloud-drive
-
-# 进程监控
-ps aux | grep cloud-drive-server
-
-# 网络连接
-sudo netstat -tlnp | grep 8000
-
-# 磁盘空间
-df -h /opt/cloud-drive
-```
-
-## 安全建议
-
-1. **防火墙配置**: 只开放必要的端口（8000）
-2. **用户权限**: 使用专用用户运行服务，避免root权限
-3. **文件权限**: 确保敏感文件只有服务用户可读
-4. **SSL/TLS**: 在生产环境使用HTTPS
-5. **定期更新**: 保持系统和依赖包的更新
-
-## 技术支持
-
-如遇到问题，请检查：
-1. 系统日志：`journalctl -u cloud-drive`
-2. 应用日志：`/opt/cloud-drive/logs/app.log`
-3. 配置文件：`/opt/cloud-drive/.env`
-4. 服务状态：`systemctl status cloud-drive`

-- Docker 20.10+
-- Docker Compose 2.0+
-- 至少 2GB 内存
-- 至少 10GB 磁盘空间
-
-### 2. 安装 Docker
-
-#### Ubuntu/Debian:
-```bash
-# 更新包索引
-sudo apt-get update
-
-# 安装必要的包
-sudo apt-get install ca-certificates curl gnupg lsb-release
-
-# 添加 Docker 官方 GPG key
-sudo mkdir -p /etc/apt/keyrings
-curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
-
-# 设置仓库
-echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
-
-# 安装 Docker Engine

-```
-
-### 3. 启动 Docker 服务
-```bash
-sudo systemctl start docker
-sudo systemctl enable docker
-```
-
-### 4. 将用户添加到 docker 组（可选）
-```bash
-sudo usermod -aG docker $USER
-# 重新登录或执行
-newgrp docker
-```
-
-## 🚀 快速部署
-
-### 方法一：使用自动部署脚本（推荐）
-
-1. 将 backend 目录上传到服务器
-2. 进入 backend 目录
-3. 给脚本添加执行权限：
-   ```bash
-   chmod +x build-docker.sh
-   ```
-4. 运行部署脚本：
-   ```bash
-   # 完整部署（构建镜像 + 运行容器）
-   ./build-docker.sh
-
-   # 或者使用 Docker Compose 部署
-   ./build-docker.sh compose
-   ```
-
-### 方法二：手动部署
-
-1. **构建镜像**
-   ```bash
-   docker build -t cloud-drive-backend:latest .
-   ```
-
-2. **运行容器**
-   ```bash
-   docker run -d \
-     --name cloud-drive-backend \
-     --restart unless-stopped \
-     -p 8002:8002 \
-     -v $(pwd)/uploads:/app/uploads \
-     -v $(pwd)/logs:/app/logs \
-     -e ENVIRONMENT=production \
-     cloud-drive-backend:latest
-   ```
-
-### 方法三：使用 Docker Compose
-
-1. **配置环境变量**
-   ```bash
-   cp .env.example .env
-   # 编辑 .env 文件，设置正确的配置
-   ```
-
-2. **启动服务**
-   ```bash
-   docker-compose up -d
-   ```
-
-## ⚙️ 配置说明
-
-### 环境变量配置
-
-创建 `.env` 文件：
-```bash
-# 数据库配置
-DATABASE_URL=mysql://username:password@mysql:3306/mytest_db
-MYSQL_ROOT_PASSWORD=your_root_password
-MYSQL_DATABASE=mytest_db
-MYSQL_USER=your_username
-MYSQL_PASSWORD=your_password
-
-# Redis 配置
-REDIS_URL=redis://redis:6379/0
-
-# 应用配置
-SECRET_KEY=your-production-secret-key
-CORS_ORIGINS=http://localhost:3003,https://yourdomain.com
-ENVIRONMENT=production
-```
-
-### 端口配置
-- 应用端口：8002
-- MySQL 端口：3306
-- Redis 端口：6379
-
-### 数据持久化
-- `./uploads` - 文件上传目录
-- `./logs` - 应用日志目录
-- `mysql_data` - MySQL 数据目录
-- `redis_data` - Redis 数据目录
-
-## 🛠️ 常用命令
-
-### 容器管理
-```bash
-# 查看容器状态
-./build-docker.sh status
-
-# 查看容器日志
-./build-docker.sh logs
-
-# 重启容器
-./build-docker.sh restart
-
-# 停止容器
-./build-docker.sh stop
-
-# 清理资源
-./build-docker.sh cleanup
-```
-
-### Docker Compose 命令
-```bash
-# 查看服务状态
-docker-compose ps
-
-# 查看日志
-docker-compose logs -f
-
-# 重启服务
-docker-compose restart
-
-# 停止服务
-docker-compose down
-
-# 更新并重启
-docker-compose up -d --build
-```
-
-## 🔍 健康检查
-
-应用包含内置的健康检查端点：
-- 端点：`http://localhost:8002/api/v1/health`
-- 检查间隔：30秒
-- 超时时间：30秒
-- 重试次数：3次
-
-手动检查：
-```bash
-curl http://localhost:8002/api/v1/health
-```
-
-## 🔧 故障排除
-
-### 1. 容器无法启动
-```bash
-# 查看容器日志
-docker logs cloud-drive-backend
-
-# 检查端口占用
-netstat -tulpn | grep 8002
-```
-
-### 2. 数据库连接失败
-- 检查数据库服务是否运行
-- 验证连接字符串是否正确
-- 确认网络连通性
-
-### 3. 文件上传问题
-- 检查 uploads 目录权限
-- 确认磁盘空间充足
-- 验证文件大小限制
-
-### 4. 内存不足

-# 检查内存使用
-free -h
-
-# 检查容器资源使用
-docker stats
-```
-
-## 📊 监控
-
-### 日志监控
-```bash
-# 实时查看日志
-tail -f logs/app.log
-
-# 查看错误日志
-grep ERROR logs/app.log
-```
-
-### 性能监控

-# Ubuntu UFW
-sudo ufw allow 8002
-sudo ufw allow 22
-sudo ufw enable
-
-# CentOS firewalld
-sudo firewall-cmd --permanent --add-port=8002/tcp
-sudo firewall-cmd --reload
-```
-
-### 2. SSL/TLS 配置
-建议使用 Nginx 或 Caddy 作为反向代理来处理 HTTPS：
-
-```nginx
-server {
-    listen 443 ssl;
-    server_name yourdomain.com;
-
-    ssl_certificate /path/to/certificate.crt;
-    ssl_certificate_key /path/to/private.key;
-
-    location / {
-        proxy_pass http://localhost:8002;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-}
-```
-
-## 📈 扩展部署
-
-### 1. 负载均衡
-使用多个容器实例配合负载均衡器：
-
-```yaml
-# docker-compose.scale.yml
-version: '3.8'
-services:
-  app:
-    image: cloud-drive-backend:latest
-    scale: 3
-    # ... 其他配置
-```
-
-### 2. 集群部署
-使用 Docker Swarm 或 Kubernetes 进行集群部署。
-
