Content-Transfer-Encoding: 8bit 这是一个重大功能更新版本，包含全面的架构重构、功能增强、文档完善和配置热加载改进。 主要变更： ✨ 新增功能 - 后端：自适应数据收集、内存池管理、网络统计监控、网络计数器回绕保护 - 前端：国际化 (i18n) 支持、WebSocket/HTTP 双模式、Pinia 状态管理 - 基础设施：Docker 支持、CI/CD 自动化、GoReleaser 跨平台发布 - 测试：新增 3,700+ 行单元测试代码 - 配置热加载：支持动态更新 servers 配置，自动断开删除服务器的连接和清理状态 📦 架构重构 - 从 workspace 结构改为单仓库结构 - 统一代码到 internal/ 目录结构 - 新增 shared/ 共享模块（日志、配置、错误处理） 📝 文档完善 - 新增 14 个完整文档（API、架构、部署、开发、故障排查） - 新增一键安装脚本（Linux/macOS/Windows） 🔧 工具链升级 - 迁移包管理器：npm → pnpm（性能提升、磁盘节省、依赖管理更严格） - 更新所有文档、脚本、CI/CD 配置以使用 pnpm - 修复 WebSocket 路径验证测试（保持向后兼容性） 🛡️ 代码质量与安全 - 修复 50+ 个 golangci-lint 检测的安全和代码质量问题 - 为 HTTP Server 添加超时配置，防止 Slowloris 攻击 - 修复 JSON 标签尾随空格导致的序列化问题 - 修复配置热重载功能失效的问题（使用指针解引用更新配置） - 修复网络计数器回绕导致的错误值问题 🔄 配置热加载改进 - 新增 DashboardService.ReloadServers() 方法 - 自动识别并删除被移除的服务器 - 自动断开被删除服务器的 WebSocket 连接 - 自动清理被删除服务器的状态数据（serverStatusMap） - 动态同步更新服务器配置 map - 热加载行为与冷启动完全一致 详见 CHANGELOG.md --- .dockerignore | 112 + .gitattributes | 33 + .github/workflows/ci.yml | 135 +

+# Ubuntu/Debian +sudo ufw allow 8900/tcp + +# CentOS/RHEL +sudo firewall-cmd --add-port=8900/tcp --permanent +sudo firewall-cmd --reload +``` + +#### 1.5 访问 Dashboard + +在浏览器中打开：`http://your-server-ip:8900` + +### 方式 2：使用二进制文件 + +#### 2.1 下载 Dashboard + +```bash +# 查看最新版本 +LATEST_VERSION=$(curl -s

+Get-EventLog -LogName Application -Source "SSSA" -Newest 20 +``` + +### 3.3 连接失败排查 + +如果服务器显示离线，请按以下步骤排查： + +#### ① 检查 Dashboard 是否正常运行 + +```bash +# Docker +docker ps | grep sssd +docker logs sssd + +# 二进制 +sudo systemctl status sss-dashboard +sudo journalctl -u sss-dashboard -n 50 +``` + +#### ② 检查 Agent 是否正常运行 + +```bash +# Linux +sudo systemctl status sssa +sudo journalctl -u sssa -n 50 + +# Windows +Get-Service -Name "SSSA" +``` + +#### ③ 验证配置文件 + +确认以下配置项完全一致： + +- Dashboard 的 `servers.id` ↔ Agent 的 `serverId` +- Dashboard 的 `servers.secret` ↔ Agent 的 `authSecret` +- Agent 的 `serverAddr` 格式正确：`ws://dashboard-ip:8900/ws-report` +- `serverAddr` 路径与 Dashboard 的 `webSocketPath` 一致（默认 `/ws-report`） + +#### ④ 检查网络连接 + +```bash +# 测试 Dashboard 端口是否可访问 +telnet your-dashboard-ip 8900 +# 或 +nc -zv your-dashboard-ip 8900 +``` + +#### ⑤ 检查防火墙 + +```bash +# Ubuntu/Debian +sudo ufw status +sudo ufw allow 8900 + +# CentOS/RHEL +sudo firewall-cmd --list-all +sudo firewall-cmd

HTTPS。详细配置请参考： + +- [反向代理配置指南](deployment/proxy.md) +- [Nginx 配置示例](deployment/proxy.md#nginx) +- [Caddy 配置示例](deployment/proxy.md#caddy) + +配置反向代理后，Agent 的 `serverAddr` 需要改为： + +```yaml +serverAddr: wss://your-domain.com/ws-report # 注意使用 wss:// +``` + +### Q3: 数据收集频率可以调整吗？ + +可以。在 Agent 配置文件中调整： + +```yaml +collectInterval: 2s # 数据收集间隔，默认 2 秒 +``` + +**建议值：** +- 高频监控：1s - 2s +- 标准监控：3s - 5s（推荐） +- 低频监控：10s - 30s + +⚠️ 注意：间隔越短，CPU 占用越高。 + +### Q4: 支持哪些操作系统？ + +**完全支持：** +- Linux（x86_64, ARM64, ARMv7） +- Windows（x86_64, ARM64） +- macOS（x86_64, ARM64/Apple Silicon） +- FreeBSD（x86_64） + +**已测试的

排查步骤 + +**① 检查 Dashboard 是否正常运行** + +```bash +# Docker 部署 +docker ps | grep sssd # 应该看到运行中的容器 +docker logs sssd # 查看 Dashboard 日志 + +# 二进制/systemd 部署 +sudo systemctl status sss-dashboard +sudo journalctl -u sss-dashboard -n 50 +``` + +**预期结果：** +- Docker 容器状态为 `Up` +- systemd 服务状态为 `active (running)` +- 日志中显示 "服务器启动成功" 或类似消息 + +**② 检查 Agent 是否正常运行** + +```bash +# Linux/macOS +sudo systemctl

"连接成功" 或 "WebSocket connected" + +**③ 验证配置文件** + +检查以下配置项是否完全一致： + +| Dashboard 配置 | Agent 配置 | 说明 | +|---------------|-----------|------| +| `servers.id` | `serverId` | 必须完全一致（区分大小写） | +|

"C:\Program Files\SSSA\sss-agent.yaml" +``` + +**④ 检查网络连通性** + +```bash +# 测试 Dashboard 端口是否可访问 +telnet your-dashboard-ip 8900 + +# 或使用 nc +nc -zv your-dashboard-ip 8900 + +# 或使用 curl +curl -I http://your-dashboard-ip:8900 +``` + +**预期结果：** +- `Connected to ...` 或 `succeeded!` +- 如果失败，说明网络不通或防火墙阻止 + +**⑤ 检查防火墙设置** + +```bash +# Ubuntu/Debian +sudo ufw status +sudo ufw allow 8900/tcp +sudo

检查 WebSocket 路径配置** + +Dashboard 的 `webSocketPath` 和 Agent 的 `serverAddr` 路径必须一致。 + +**Dashboard 配置：** + +```yaml +webSocketPath: /ws-report # 默认值，推荐以 '/' 开头 +``` + +**Agent 配置：** + +```yaml
