+# Linux 服务器部署运维设计
+
+## 1. 背景
+
+`system-ops/deploy` 当前只提供系统部署菜单的基础入口：
+
+- `GET /deploy/overview`
+- `DeployController`
+- `DeployService`
+- `DeployOverviewVO`
+
+本次需求是在 `deploy` 模块中补充 Linux 服务器远程运维能力。用户可以维护 Linux 服务器连接配置，基于 SSH/SFTP 连接服务器，完成远程文件上传、下载和基础命令终端操作。命令终端目标体验接近 Xshell 的基础能力。
+
+当前仓库没有前端代码，本设计只定义页面布局、接口契约、后端模块拆分、数据存储和验证方式，不实现真实前端页面。
+
+## 2. 范围确认
+
+本期只支持 Linux 服务器。
+
+本期包含：
+
+- Linux SSH 连接配置的新增、编辑、删除、查询。
+- SSH 连接测试。
+- SFTP 文件列表、上传、下载、删除、新建目录。
+- SSH Shell 基础命令交互。
+- 前端单页运维工作台布局设计。
+- 连接配置使用文件方式存储，不新建数据库表。
+
+本期不包含：
+
+- Windows 服务器。
+- FTP 协议。
+- 数据库存储连接配置。
+- 部署任务编排。
+- 命令审批、命令黑名单、命令历史。
+- 批量文件压缩下载。
+- 数据库专用客户端封装。
+- Maven 编译、打包、测试。
+
+说明：需求中提到的 “FPT” 本期按 Linux 服务器常用能力理解为 SFTP。SFTP 复用 SSH 账号、密码和端口，比单独 FTP 更适合本期场景。
+
+## 3. 总体方案
+
+推荐采用 “SSH/SFTP + WebSocket 终端” 方案：
+
+- 服务器连接配置保存到本地 JSON 文件。
+- 后端通过 SSH 建立 Linux 连接。
+- 文件操作通过 SFTP 通道完成。
+- 终端操作通过 SSH Shell 通道完成。
+- 前端通过 WebSocket 与后端交换终端输入输出。
+
+该方案可以复用同一份服务器连接配置，不需要引入 Windows 远程协议，也能满足类 Xshell 的基础交互需求。
+
+## 4. 前端页面布局
+
+页面路径建议沿用当前菜单路径：
+
+```text
+/systemOps/deploy
+```
+
+页面采用三块工作区：
+
+- 左侧：服务器列表。
+- 中间：远程文件管理。
+- 右侧：连接详情和快捷操作。
+- 底部：SSH 终端区。
+
+推荐布局：
+
+```text

+### 4.1 服务器列表
+
+左侧服务器列表用于选择当前操作目标。
+
+展示字段：
+
+| 字段 | 说明 |
+|---|---|
+| 名称 | 服务器显示名称 |
+| 主机地址 | IP 或域名 |
+| SSH 端口 | 默认 22 |
+| 连接状态 | 未测试、连接成功、连接失败 |
+
+交互：
+
+- 支持按名称、主机地址搜索。
+- 点击服务器后加载连接详情，并将文件管理区切换到该服务器。
+- 列表项提供编辑、删除、测试连接入口。
+- 删除连接前必须二次确认。
+
+### 4.2 连接配置弹窗
+
+新增和编辑使用同一个弹窗。
+
+字段：
+
+| 字段 | 是否必填 | 说明 |
+|---|---|---|
+| 名称 | 是 | 页面展示名称 |
+| 主机地址 | 是 | Linux 服务器 IP 或域名 |
+| SSH 端口 | 是 | 默认 22，范围 1-65535 |
+| 用户名 | 是 | SSH 登录用户 |
+| 密码 | 新增必填 | 编辑时留空表示不修改 |
+| 备注 | 否 | 环境说明 |
+
+按钮：
+
+- 测试连接。
+- 保存。
+- 取消。
+
+密码规则：
+
+- 新增连接时密码必填。
+- 编辑连接时密码不回显。
+- 编辑时密码为空表示沿用原密码。
+- 查询列表和详情接口均不返回密码。
+
+### 4.3 远程文件管理
+
+中间文件管理区基于当前选中的服务器工作。
+
+顶部路径栏：
+
+- 展示当前远程目录，例如 `/opt/app`。
+- 支持返回上级目录。
+- 支持点击面包屑跳转到上级路径。
+
+工具栏：
+
+- 上传。
+- 下载。
+- 新建目录。
+- 删除。
+- 刷新。
+
+文件表格字段：
+
+| 字段 | 说明 |
+|---|---|
+| 名称 | 文件或目录名称 |
+| 类型 | 文件、目录、软链接 |
+| 大小 | 文件大小，目录可为空 |
+| 权限 | Linux 权限字符串 |
+| 修改时间 | 远程文件修改时间 |
+
+交互规则：
+
+- 双击目录进入下级目录。
+- 下载只支持普通文件。
+- 删除文件或目录前必须二次确认。
+- 本期支持单文件上传和单文件下载。
+- 上传目标目录为当前路径。
+- 下载目录、批量压缩下载不在本期范围。
+
+### 4.4 SSH 终端区
+
+底部终端区用于执行 Linux 命令。
+
+交互规则：
+
+- 点击“打开终端”后创建 SSH Shell 会话。
+- 前端输入通过 WebSocket 实时发送给后端。
+- 后端将 Shell 输出通过 WebSocket 实时推送给前端。
+- 本期建议限制为每台服务器最多一个终端会话。
+- 关闭终端 Tab 时通知后端释放 SSH 会话。
+- 终端断开后显示状态，不自动重连。
+
+用户可以在终端中自行执行数据库命令，例如：
+
+```bash
+mysql -uroot -p
+psql -h 127.0.0.1 -U postgres
+redis-cli
+```
+
+后端不解析数据库命令，也不保存命令历史。
+
+## 5. 后端结构设计
+
+在 `system-ops/deploy` 模块内按职责新增类，保留现有 `DeployController` 的 `/deploy/overview`。
+
+建议结构：
+
+```text
+system-ops/deploy/src/main/java/com/njcn/gather/systemops/deploy/
+├── config/
+├── controller/
+├── pojo/param/
+├── pojo/vo/
+├── pojo/dto/
+├── repository/
+├── service/
+├── service/impl/
+└── websocket/
+```
+
+职责拆分：
+
+| 类 | 职责 |
+|---|---|
+| `DeployServerController` | 连接配置查询、新增、编辑、删除、测试连接 |
+| `DeployFileController` | SFTP 文件列表、上传、下载、删除、新建目录 |
+| `DeployTerminalWebSocketHandler` | SSH 终端 WebSocket 输入输出转发 |
+| `DeployServerConfigService` | 连接配置业务校验和编排 |
+| `DeployServerConfigRepository` | JSON 文件读写 |
+| `DeploySftpService` | SFTP 文件操作 |
+| `DeploySshTerminalService` | SSH Shell 会话创建、输入、输出、关闭 |
+| `DeployCryptoService` | 密码加密和解密 |
+| `DeployProperties` | deploy 配置项绑定 |
+
+## 6. 连接配置存储
+
+连接配置不入库，使用 JSON 文件落盘。存储目录通过配置指定。
+
+建议配置：
+
+```yaml
+deploy:
+  storage-dir: ${log.homeDir}/deploy
+  terminal-idle-timeout-minutes: 30
+```
+
+`deploy.crypto-key` 不建议在默认 `application.yml` 中配置明文值。后续实现时可通过环境覆盖或外部配置提供，业务代码只读取配置，不写死密钥。
+
+落盘文件：
+
+```text
+D:\logs\deploy\deploy-server-connections.json
+```
+
+JSON 结构：
+
+```json
+{
+  "servers": [
+    {
+      "id": "uuid",
+      "name": "测试服务器",
+      "host": "192.168.1.10",
+      "sshPort": 22,
+      "username": "root",
+      "password": "加密密文",
+      "description": "测试环境",
+      "createdTime": "2026-05-21 14:00:00",
+      "updatedTime": "2026-05-21 14:00:00"
+    }
+  ]
+}
+```
+
+写文件规则：
+
+- 启动时如果文件不存在，自动创建空配置文件。
+- 读写方法集中在 `DeployServerConfigRepository`。
+- 写入时先写临时文件，再替换正式文件，避免进程中断导致 JSON 损坏。
+- 保存和删除操作需要加进程内锁，避免并发写入互相覆盖。
+
+密码规则：
+
+- 密码必须加密后落盘。
+- 接口返回不包含密码。
+- 日志不打印密码。
+- 优先复用项目已有加密能力；如没有合适工具，则在 `deploy` 内封装 AES 加解密组件。
+- 加密密钥通过配置提供，不在业务代码中硬编码。
+
+## 7. 接口设计
+
+接口风格沿用当前仓库常见写法：查询和变更优先使用 `POST`，返回 `HttpResult<T>`。
+
+### 7.1 连接配置接口
+
+| 方法 | 路径 | 说明 |
+|---|---|---|
+| `POST` | `/deploy/server/list` | 查询服务器连接配置列表 |
+| `POST` | `/deploy/server/add` | 新增服务器连接配置 |
+| `POST` | `/deploy/server/update` | 修改服务器连接配置 |
+| `POST` | `/deploy/server/delete` | 删除服务器连接配置 |
+| `POST` | `/deploy/server/test` | 测试 SSH 连接 |
+
+列表返回字段：
+
+| 字段 | 说明 |
+|---|---|
+| `id` | 连接 ID |
+| `name` | 服务器名称 |
+| `host` | 主机地址 |
+| `sshPort` | SSH 端口 |
+| `username` | 用户名 |
+| `description` | 备注 |
+| `createdTime` | 创建时间 |
+| `updatedTime` | 更新时间 |
+
+新增参数：
+
+| 字段 | 是否必填 |
+|---|---|
+| `name` | 是 |
+| `host` | 是 |
+| `sshPort` | 是 |
+| `username` | 是 |
+| `password` | 是 |
+| `description` | 否 |
+
+编辑参数：
+
+| 字段 | 是否必填 | 说明 |
+|---|---|---|
+| `id` | 是 | 连接 ID |
+| `name` | 是 | 服务器名称 |
+| `host` | 是 | 主机地址 |
+| `sshPort` | 是 | SSH 端口 |
+| `username` | 是 | 用户名 |
+| `password` | 否 | 为空表示不修改 |
+| `description` | 否 | 备注 |
+
+### 7.2 文件接口
+
+| 方法 | 路径 | 说明 |
+|---|---|---|
+| `POST` | `/deploy/file/list` | 查询远程目录文件列表 |
+| `POST` | `/deploy/file/mkdir` | 新建远程目录 |
+| `POST` | `/deploy/file/delete` | 删除远程文件或目录 |
+| `POST` | `/deploy/file/upload` | 上传本地文件到远程目录 |
+| `POST` | `/deploy/file/download` | 下载远程普通文件 |
+
+文件列表参数：
+
+| 字段 | 是否必填 | 说明 |
+|---|---|---|
+| `serverId` | 是 | 服务器连接 ID |
+| `path` | 是 | 远程目录路径 |
+
+文件列表返回字段：
+
+| 字段 | 说明 |
+|---|---|
+| `name` | 文件名 |
+| `path` | 完整路径 |
+| `type` | `FILE`、`DIRECTORY`、`LINK` |
+| `size` | 文件大小 |
+| `permissions` | 权限字符串 |
+| `modifiedTime` | 修改时间 |
+
+下载接口直接写入 `HttpServletResponse`。下载文件名沿用远程文件名，不追加日期；仓库“导出或生成文件追加日期”的规则适用于后端生成或导出文件，本功能是下载远程已有文件，不改变原文件名。
+
+### 7.3 终端 WebSocket
+
+终端连接：
+
+```text
+WebSocket /deploy/terminal?serverId={serverId}
+```
+
+前端发送输入：
+
+```json
+{
+  "type": "input",
+  "data": "ls -la\n"
+}
+```
+
+前端发送窗口大小：
+
+```json
+{
+  "type": "resize",
+  "cols": 120,
+  "rows": 30
+}
+```
+
+后端输出：
+
+```json
+{
+  "type": "output",
+  "data": "total 20\r\n..."
+}
+```
+
+后端状态：
+
+```json
+{
+  "type": "status",
+  "status": "CONNECTED"
+}
+```
+
+异常消息：
+
+```json
+{
+  "type": "error",
+  "message": "SSH连接失败"
+}
+```
+
+## 8. 参数校验
+
+后端至少补充以下校验：
+
+- 服务器名称不能为空。
+- 主机地址不能为空。
+- SSH 端口范围为 `1-65535`。
+- 用户名不能为空。
+- 新增连接时密码不能为空。
+- 编辑连接时 `id` 必须存在。
+- 删除连接时 `id` 必须存在。
+- 同一主机、端口、用户名组合不建议重复保存。
+- 文件路径不能为空。
+- 文件上传目标必须是远程目录。
+- 下载目标必须是远程普通文件。
+- 删除路径不能为空，不能删除空路径或根目录 `/`。
+- 新建目录名称不能为空，不能包含路径分隔符。
+
+## 9. 安全与资源控制
+
+安全规则：
+
+- 密码不明文落盘。
+- 接口返回不包含密码。
+- 日志不打印密码、终端输入内容、文件内容。
+- 终端不保存命令历史。
+- 文件路径需要做基础规范化，避免空路径、非法路径和目录穿越。
+- 下载只允许下载普通文件。
+
+资源规则：
+
+- SSH 连接测试设置连接超时，例如 5 秒。
+- SFTP 操作每次请求创建短连接，操作完成后释放。
+- 终端会话保持长连接，关闭 WebSocket 后释放 SSH Session 和 Channel。
+- 终端会话设置空闲超时，默认 30 分钟。
+- 本期每台服务器最多保留一个终端会话。
+
+## 10. 依赖建议
+
+后续实现 SSH/SFTP 时建议优先选择 Java 8 可用、项目易接入的 SSH 客户端库，例如 JSch 或 sshj。
+
+选择标准：
+
+- 支持 SSH 密码登录。
+- 支持 SFTP 文件操作。
+- 支持 Shell Channel。
+- 能在 Spring Boot 2.3 和 Java 8 下稳定使用。
+
+最终依赖需要写入 `system-ops/deploy/pom.xml`，不影响其他模块。
+
+## 11. 错误处理
+
+连接测试需要区分常见错误：
+
+| 场景 | 返回说明 |
+|---|---|
+| 主机不可达 | 连接服务器失败 |
+| 端口不通 | SSH端口连接失败 |
+| 账号或密码错误 | SSH认证失败 |
+| SFTP 打开失败 | 文件通道打开失败 |
+| 终端打开失败 | Shell通道打开失败 |
+
+接口层仍使用项目现有 `HttpResult` 和 `CommonResponseEnum` 风格。具体错误文案由 Service 返回给 Controller，不新增全局异常体系。
+
+## 12. 验证方式
+
+默认不执行 Maven 编译、打包、测试命令。后续实现完成后按以下方式验证：
+
+- 检查 `deploy` 新增代码只位于 `system-ops/deploy`。
+- 新增连接后，接口返回和 JSON 文件内容一致。
+- 编辑连接时密码留空不会覆盖原密码。
+- 删除连接后，JSON 文件同步移除对应记录。
+- 查询接口不返回密码。
+- JSON 文件中密码不是明文。
+- 测试连接能识别成功、主机不可达、端口不通、账号密码错误。
+- 文件列表能展示远程目录内容。
+- 上传文件后远程目录可见。
+- 下载普通文件内容与远程文件一致。
+- 删除文件或目录后远程路径不存在。
+- 新建目录后远程路径存在。
+- 终端能打开 Linux Shell，执行 `pwd`、`ls -la`、`mysql --version` 等基础命令。
+- 关闭终端后，后端 SSH 会话被释放。
+
+## 13. 后续扩展
+
+后续如需求增加，可以在当前方案基础上扩展：
+
+- SSH 私钥登录。
+- 多终端 Tab。
+- 命令审计和历史记录。
+- 命令黑名单或审批。
+- 部署脚本编排。
+- 文件批量上传和批量下载。
+- Windows WinRM 或 PowerShell Remoting。
+
+这些能力不进入本期实现，避免当前 `deploy` 模块从基础入口一次扩张为完整运维平台。

+# dbms 模块说明
+
+## 模块定位
+
+`dbms` 是 `system-ops` 下的数据库运维模块，当前面向 Oracle 数据库提供连接配置、连接测试、表列表查询、备份、恢复、任务状态查询和删除接口。
+
+## 当前接口
+
+- `GET /database/overview`
+  - 查询数据库运维概览信息。
+- `POST /database/connections/list`
+  - 查询数据库连接配置。
+- `POST /database/connections/add`
+  - 新增 Oracle 数据库连接配置。
+- `POST /database/connections/update`
+  - 修改 Oracle 数据库连接配置。
+- `POST /database/connections/delete`
+  - 删除数据库连接配置。
+- `POST /database/connections/test`
+  - 测试 Oracle 数据库连接。
+- `POST /database/connections/tables`
+  - 查询 Oracle 表列表。
+- `POST /database/backups/create`
+  - 创建备份任务，默认使用 `DATA_PUMP`，可选 `JDBC_EXPORT`。
+- `POST /database/backups/tasks/list`
+  - 查询备份任务列表。
+- `GET /database/backups/tasks/status`
+  - 查询任务状态。
+- `POST /database/backups/files/list`
+  - 查询备份文件记录。
+- `POST /database/restores/create`
+  - 创建恢复任务。
+- `GET /database/restores/tasks/status`
+  - 查询恢复任务状态。
+- `POST /database/delete/backup-file`
+  - 删除备份文件，要求 `confirmText=确认删除`。
+- `POST /database/delete/task`
+  - 删除任务记录，要求 `confirmText=确认删除`。
+
+## 数据脚本
+
+- `src/main/resources/sql/system-ops/system-ops-init.sql`
+  - 系统运维菜单初始化脚本。
+- `src/main/resources/sql/system-ops/dbms-database-ops-init.sql`
+  - 数据库运维连接、任务、备份文件和恢复记录表结构。
+
+## 配置项
+
+建议通过环境配置覆盖：
+
+```yaml
+dbms:
+  backup:
+    storage-path: D:/dbms-backup
+    default-max-file-size-mb: 512
+  tools:
+    expdp-path:
+    impdp-path:
+```
+
+说明：
+
+- `backup.storage-path`
+  - `JDBC_EXPORT` 生成的 CSV 和元数据 JSON 的受管根目录。
+- `tools.expdp-path`、`tools.impdp-path`
+  - Oracle Data Pump 工具路径；为空时尝试走系统 `PATH`。
+
+## 当前行为
+
+- 一期仅支持 `ORACLE`。
+- 连接密码支持两种运行方式：
+  - 前端每次传 `temporaryPassword`。
+  - 连接已保存密文，且公共 `Sm4Utils` 提供 `decryptData_ECB` 时由后端自动解密复用。
+- 新增连接前的测试接口允许只传 `temporaryPassword`，不强制把密码写进 `connection.password`。
+- 备份任务异步执行，只有实际文件生成成功后才会写入 `dbms_backup_file` 记录。
+- `JDBC_EXPORT` 当前会生成两类文件：
+  - 主数据文件：`*.csv`
+  - 元数据文件：`*_metadata_yyyyMMdd_<taskNo>.json`
+- `JDBC_EXPORT` 恢复依赖元数据文件，不再允许缺少元数据直接发起恢复。
+- 删除备份文件时，会校验目标路径必须位于受管备份目录下，避免误删非备份文件。
+
+## 当前限制
+
+- `DATA_PUMP` 仍依赖部署机器可执行 `expdp`、`impdp`，并且 Oracle 侧已准备好 `directory` 对象和权限。
+- 当前代码要求 `DATA_PUMP` 连接配置里补齐可管理的 `directoryPath`，否则虽然 Oracle 端可能已导出成功，后端无法安全管理文件记录与删除。
+- `JDBC_EXPORT` 恢复当前仅覆盖表数据，不承诺恢复索引、约束、触发器、序列、存储过程、权限等 Oracle 对象。
+- `TIME_RANGE` 模式当前只在 `JDBC_EXPORT` 场景真正参与查询过滤；`DATA_PUMP` 尚未接入 Oracle `QUERY` 参数。
+- `SIZE_SPLIT` 参数目前已做入参校验，但尚未实现真正的导出分片。
+- 本轮仅完成代码路径和文档收口，未执行 `mvn` 编译、测试或真实库联调。
