 # navigation-app
 
+from deepseek
+
+## 详细部署流程
+
+### 1. 开发环境准备
+
+1. **安装Go语言环境** (仅开发机需要):
+
+   bash
+
+   复制
+
+   ```
+   # Linux
+   sudo apt update && sudo apt install -y golang
+   
+   # Mac
+   brew install go
+   
+   # Windows
+   # 从 https://golang.org/dl/ 下载安装包
+   ```
+
+2. **初始化Go模块**:
+
+   bash
+
+   复制
+
+   ```
+   cd backend
+   go mod init navigation/backend
+   go mod tidy
+   ```
+
+### 2. 编译应用程序
+
+1. **编译Linux可执行文件**:
+
+   bash
+
+   复制
+
+   ```
+   make build
+   ```
+
+   这会在`bin/`目录下生成`navigation-server`二进制文件
+
+### 3. VPS部署步骤
+
+1. **上传文件到VPS**:
+
+   bash
+
+   复制
+
+   ```
+   scp -r bin/ navigation-server config/ frontend/ data/ user@your_vps_ip:/opt/navigation-app
+   ```
+
+2. **SSH登录VPS**:
+
+   bash
+
+   复制
+
+   ```
+   ssh user@your_vps_ip
+   ```
+
+3. **设置文件权限**:
+
+   bash
+
+   复制
+
+   ```
+   cd /opt/navigation-app
+   chmod +x bin/navigation-server
+   mkdir -p data
+   chmod 700 data
+   ```
+
+4. **运行应用程序** (测试运行):
+
+   bash
+
+   复制
+
+   ```
+   cd /opt/navigation-app
+   ./bin/navigation-server
+   ```
+
+5. **配置持久化运行** (使用systemd):
+
+   创建服务文件`/etc/systemd/system/navigation.service`:
+
+   ini
+
+   复制
+
+   ```
+   [Unit]
+   Description=Navigation Server
+   After=network.target
+   
+   [Service]
+   Type=simple
+   User=www-data
+   WorkingDirectory=/opt/navigation-app
+   ExecStart=/opt/navigation-app/bin/navigation-server
+   Restart=always
+   RestartSec=10
+   
+   [Install]
+   WantedBy=multi-user.target
+   ```
+
+   启用并启动服务:
+
+   bash
+
+   复制
+
+   ```
+   sudo systemctl daemon-reload
+   sudo systemctl enable navigation
+   sudo systemctl start navigation
+   ```
+
+6. **验证服务运行**:
+
+   bash
+
+   复制
+
+   ```
+   sudo systemctl status navigation
+   curl http://localhost:8080/api/sites
+   ```
+
+### 4. 配置反向代理 (可选，推荐)
+
+使用Nginx作为反向代理:
+
+1. **安装Nginx**:
+
+   bash
+
+   复制
+
+   ```
+   sudo apt update && sudo apt install -y nginx
+   ```
+
+2. **创建配置文件** `/etc/nginx/sites-available/navigation`:
+
+   nginx
+
+   复制
+
+   ```
+   server {
+       listen 80;
+       server_name yourdomain.com;
+   
+       location / {
+           proxy_pass http://127.0.0.1:8080;
+           proxy_set_header Host $host;
+           proxy_set_header X-Real-IP $remote_addr;
+           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+       }
+   }
+   ```
+
+3. **启用配置**:
+
+   bash
+
+   复制
+
+   ```
+   sudo ln -s /etc/nginx/sites-available/navigation /etc/nginx/sites-enabled/
+   sudo nginx -t
+   sudo systemctl reload nginx
+   ```
+
+4. **配置HTTPS (使用Let's Encrypt)**:
+
+   bash
+
+   复制
+
+   ```
+   sudo apt install -y certbot python3-certbot-nginx
+   sudo certbot --nginx -d yourdomain.com
+   ```
+
+## 维护与管理
+
+### 常用命令
+
+- **查看日志**:
+
+  bash
+
+  复制
+
+  ```
+  journalctl -u navigation -f
+  ```
+
+- **重启服务**:
+
+  bash
+
+  复制
+
+  ```
+  sudo systemctl restart navigation
+  ```
+
+- **备份数据库**:
+
+  bash
+
+  复制
+
+  ```
+  cp /opt/navigation-app/data/navigation.db /path/to/backup/navigation_$(date +%F).db
+  ```
+
+### 更新流程
+
+1. 本地修改代码后重新编译:
+
+   bash
+
+   复制
+
+   ```
+   make build
+   ```
+
+2. 上传新版本到VPS:
+
+   bash
+
+   复制
+
+   ```
+   scp bin/navigation-server user@your_vps_ip:/opt/navigation-app/bin/
+   ```
+
+3. 重启服务:
+
+   bash
+
+   复制
+
+   ```
+   ssh user@your_vps_ip
+   sudo systemctl restart navigation
+   ```
+
+这个方案提供了完整的、生产就绪的Go后端实现，具有以下优点：
+
+1. 单个静态二进制文件，部署简单
+2. 使用SQLite数据库，无需额外服务
+3. 完整的CRUD API实现
+4. 包含生产环境部署配置
+5. 易于维护和更新
