+# 设计时 DbContext 配置指引
+
+> 目的：在执行 `dotnet ef` 命令时无需硬编码数据库连接，可根据 appsettings 与环境变量自动加载。本文覆盖环境变量设置、配置目录指定等细节。
+
+## 一、设计时工厂读取逻辑概述
+设计时工厂（`DesignTimeDbContextFactoryBase<T>`）按下面顺序解析连接串：
+1. 若设置了 `TAKEOUTSAAS_APP_CONNECTION` / `TAKEOUTSAAS_IDENTITY_CONNECTION` / `TAKEOUTSAAS_DICTIONARY_CONNECTION` 等环境变量，则优先使用。
+2. 否则查找配置文件：
+   - 从当前目录开始向上找到含 `TakeoutSaaS.sln` 的仓库根。
+   - 依次检查 `src/Api/TakeoutSaaS.AdminApi`、`src/Api/TakeoutSaaS.UserApi`、`src/Api/TakeoutSaaS.MiniApi` 等目录，如果存在 `appsettings.json` 或 `appsettings.{Environment}.json` 则加载。
+   - 若未找到，可通过环境变量 `TAKEOUTSAAS_APPSETTINGS_DIR` 指定包含 appsettings 文件的目录。
+
+配置结构示例（出现在 AdminApi/MiniApi/UserApi 的 appsettings）：
+```json
+"Database": {
+  "DataSources": {
+    "AppDatabase": {
+      "Write": "Host=120.53...;Database=takeout_app_db;Username=...;Password=...",
+      "Reads": [
+        "Host=120.53...;Database=takeout_app_db;Username=...;Password=..."
+      ]
+    },
+    "IdentityDatabase": {
+      "Write": "...",
+      "Reads": [ "..." ]
+    },
+    "DictionaryDatabase": {
+      "Write": "...",
+      "Reads": [ "..." ]
+    }
+  }
+}
+```
+设计时工厂会根据数据源名称（`DatabaseConstants.AppDataSource` 等）读取 `Write` 连接串，实现与运行时一致。
+
+## 二、环境变量配置
+### 1. Windows PowerShell
+```powershell
+# 指向包含 appsettings.json 的目录
+$env:TAKEOUTSAAS_APPSETTINGS_DIR = \"D:\\HAZCode\\TakeOut\\src\\Api\\TakeoutSaaS.AdminApi\"
+
+#（可选）覆盖 AppDatabase 连接串
+$env:TAKEOUTSAAS_APP_CONNECTION = \"Host=120.53.222.17;Port=5432;Database=takeout_app_db;Username=app_user;Password=***\"
+
+#（可选）覆盖 IdentityDatabase 连接串
+$env:TAKEOUTSAAS_IDENTITY_CONNECTION = \"Host=...;Database=takeout_identity_db;Username=...;Password=...\"
+
+#����ѡ������ DictionaryDatabase ���Ӵ�
+$env:TAKEOUTSAAS_DICTIONARY_CONNECTION = "Host=...;Database=takeout_dictionary_db;Username=...;Password=..."
+```
+
+### 2. Linux / macOS
+```bash
+export TAKEOUTSAAS_APPSETTINGS_DIR=/home/user/TakeOut/src/Api/TakeoutSaaS.AdminApi
+export TAKEOUTSAAS_APP_CONNECTION=\"Host=120.53.222.17;Port=5432;Database=takeout_app_db;Username=app_user;Password=***\"
+export TAKEOUTSAAS_IDENTITY_CONNECTION=\"Host=...;Database=takeout_identity_db;Username=...;Password=...\"
+export TAKEOUTSAAS_DICTIONARY_CONNECTION="Host=...;Database=takeout_dictionary_db;Username=...;Password=..."
+```
+
+> 注意：若设置了 `TAKEOUTSAAS_APP_CONNECTION`，则无需在 appsettings 中提供 `Write` 连接串，反之亦然。不要将明文密码写入代码仓库，建议使用 Secret Manager 或部署环境的安全存储。
+
+## 三、执行脚本示例
+完成上述环境变量配置后即可执行：
+```powershell
+# TakeoutAppDbContext（业务库）
+dotnet tool run dotnet-ef database update `
+  --project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --startup-project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --context TakeoutSaaS.Infrastructure.App.Persistence.TakeoutAppDbContext
+
+# IdentityDbContext（身份库）
+dotnet tool run dotnet-ef database update `
+  --project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --startup-project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --context TakeoutSaaS.Infrastructure.Identity.Persistence.IdentityDbContext
+
+# DictionaryDbContext（字典库）
+dotnet tool run dotnet-ef database update `
+  --project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --startup-project src/Infrastructure/TakeoutSaaS.Infrastructure/TakeoutSaaS.Infrastructure.csproj `
+  --context TakeoutSaaS.Infrastructure.Dictionary.Persistence.DictionaryDbContext
+```
+
+若需迁移 Identity/Dictionary 等上下文，替换 `--context` 参数为对应类型即可。
+
+## 四、常见问题
+1. **未找到 appsettings**：确保 `TAKEOUTSAAS_APPSETTINGS_DIR` 指向存在 `appsettings.json` 的目录，或将命令在 API 项目目录中执行。
+2. **密码错误**：确认远程 PostgreSQL 用户/密码是否与 appsettings 或环境变量一致，避免在 CLI 中使用默认的账号。
+3. **多环境配置**：`ASPNETCORE_ENVIRONMENT` 变量可控制加载 `appsettings.{Environment}.json`；默认是 Development。

+# PostgreSQL 与 Redis 接入手册
+
+> 本文档补齐 `Document/10_TODO.md` 中“Postgres/Redis 接入文档与 IaC/脚本”的要求，统一描述连接信息、账号权限、运维流程，以及可复用的部署脚本位置。
+
+## 1. 运行环境总览
+
+| 组件 | 地址/端口 | 主要数据库/实例 | 说明 |
+| --- | --- | --- | --- |
+| PostgreSQL | `120.53.222.17:5432` | `takeout_app_db`、`takeout_identity_db`、`takeout_dictionary_db`、`takeout_hangfire_db` | 线上实例，所有业务上下文共用。 |
+| Redis | `49.232.6.45:6379` | 单节点 | 业务缓存/登录限流/刷新令牌存储。 |
+
+> 注意：所有业务账号都只具备既有库的读写权限，无 `CREATEDB`。若需新库，需使用平台管理员账号（`postgres`）或联系 DBA。
+
+## 2. 账号与库映射
+
+| 数据库 | 角色 | 密码 | 用途 |
+| --- | --- | --- | --- |
+| `takeout_app_db` | `app_user` | `AppUser112233` | 业务域 (`TakeoutAppDbContext`) |
+| `takeout_identity_db` | `identity_user` | `IdentityUser112233` | 身份域 (`IdentityDbContext`) |
+| `takeout_dictionary_db` | `dictionary_user` | `DictionaryUser112233` | 字典域 (`DictionaryDbContext`) |
+| `takeout_hangfire_db` | `hangfire_user` | `HangFire112233` | 后台调度/Hangfire |
+
+Redis 密码：`MsuMshk112233`，见 `appsettings.*.json -> Redis`。
+
+## 3. 环境变量/配置注入
+
+### PowerShell
+
+```powershell
+$env:TAKEOUTSAAS_APPSETTINGS_DIR = "D:\HAZCode\TakeOut\src\Api\TakeoutSaaS.AdminApi"
+$env:TAKEOUTSAAS_APP_CONNECTION = "Host=120.53.222.17;Port=5432;Database=takeout_app_db;Username=app_user;Password=AppUser112233;Pooling=true"
+$env:TAKEOUTSAAS_IDENTITY_CONNECTION = "Host=120.53.222.17;Port=5432;Database=takeout_identity_db;Username=identity_user;Password=IdentityUser112233;Pooling=true"
+$env:TAKEOUTSAAS_DICTIONARY_CONNECTION = "Host=120.53.222.17;Port=5432;Database=takeout_dictionary_db;Username=dictionary_user;Password=DictionaryUser112233;Pooling=true"
+```
+
+### Bash
+
+```bash
+export TAKEOUTSAAS_APPSETTINGS_DIR=/home/user/TakeOut/src/Api/TakeoutSaaS.AdminApi
+export TAKEOUTSAAS_APP_CONNECTION="Host=120.53.222.17;Port=5432;Database=takeout_app_db;Username=app_user;Password=AppUser112233;Pooling=true"
+export TAKEOUTSAAS_IDENTITY_CONNECTION="Host=120.53.222.17;Port=5432;Database=takeout_identity_db;Username=identity_user;Password=IdentityUser112233;Pooling=true"
+export TAKEOUTSAAS_DICTIONARY_CONNECTION="Host=120.53.222.17;Port=5432;Database=takeout_dictionary_db;Username=dictionary_user;Password=DictionaryUser112233;Pooling=true"
+```
+
+Redis 连接字符串直接写入 `appsettings.*.json` 即可，如：
+
+```jsonc
+"Redis": "49.232.6.45:6379,password=MsuMshk112233,abortConnect=false"
+```
+
+## 4. 运维指南
+
+### PostgreSQL
+
+1. **只读账号验证**
+   ```powershell
+   psql "host=120.53.222.17 port=5432 dbname=takeout_app_db user=app_user password=AppUser112233"
+   ```
+2. **备份**
+   ```bash
+   pg_dump -h 120.53.222.17 -p 5432 -U postgres -F c -d takeout_app_db -f backup/takeout_app_db_$(date +%Y%m%d).dump
+   pg_dumpall -h 120.53.222.17 -p 5432 -U postgres > backup/all_$(date +%Y%m%d).sql
+   ```
+3. **恢复**
+   ```bash
+   pg_restore -h 120.53.222.17 -p 5432 -U postgres -d takeout_app_db backup/takeout_app_db_xxx.dump
+   psql -h 120.53.222.17 -p 5432 -U postgres -f backup/all_yyyymmdd.sql
+   ```
+4. **账号/权限策略**
+   - `app_user` / `identity_user` / `dictionary_user` 拥有 `CONNECT`、`TEMP`、Schema `public` 的 CRUD 权限。
+   - `hangfire_user` 仅能访问 `takeout_hangfire_db`，不可访问业务库。
+   - 创建新表/列时，通过 EF Migration 自动添加 COMMENT。
+
+### Redis
+
+1. **连接验证**
+   ```bash
+   redis-cli -h 49.232.6.45 -p 6379 -a MsuMshk112233 ping
+   ```
+2. **备份**
+   ```bash
+   redis-cli -h 49.232.6.45 -p 6379 -a MsuMshk112233 save        # 触发 RDB
+   redis-cli -h 49.232.6.45 -p 6379 -a MsuMshk112233 bgsave      # 后台
+   ```
+   RDB/AOF 文件在服务器 `redis.conf` 定义的目录（默认 `/var/lib/redis`）。
+3. **常见运维项**
+   - `CONFIG GET dir` / `CONFIG GET dbfilename` 可查看持久化路径。
+   - `INFO memory` 监控内存；开启 `maxmemory` + `allkeys-lru` 保护。
+
+## 5. IaC / 脚本
+
+| 文件 | 说明 |
+| --- | --- |
+| `deploy/postgres/create_databases.sql` | 基于 `postgres` 管理员执行，创建四个业务库及角色、授予权限、补 COMMENT。 |
+| `deploy/postgres/bootstrap.ps1` | PowerShell 包装脚本，调用 `psql` 执行上面的 SQL（默认读取 `postgres` 管理员账号）。 |
+| `deploy/postgres/README.md` | 介绍如何在本地/测试环境执行 bootstrap 并校验连接。 |
+| `deploy/redis/docker-compose.yml` | 可复用的 Redis 部署（Redis 7 + AOF），便于本地或测试环境一键拉起。 |
+| `deploy/redis/redis.conf` | compose/裸机均可共用的配置（`requirepass`、持久化等已写好）。 |
+| `deploy/redis/README.md` | 说明如何使用 compose 或将 `redis.conf` 部署到现有实例。 |
+
+> 线上目前为裸机安装（非容器），如需创建新环境/快速恢复，可直接运行上述脚本达到同样配置；即使在现有机器上，也可把 SQL/配置当作“最终规范”确保环境一致性。

+# PostgreSQL 部署脚本
+
+本目录提供在测试/预发布环境快速拉起 PostgreSQL 的脚本，复用线上同名数据库与账号，方便迁移/恢复。
+
+## 目录结构
+
+- `create_databases.sql`：创建四个业务库与对应角色（可多次执行，存在则跳过）。
+- `bootstrap.ps1`：PowerShell 包装脚本，调用 `psql` 执行 SQL。
+
+## 前置条件
+
+1. 已安装 PostgreSQL 12+，并能以管理员身份访问（默认使用 `postgres`）。
+2. 本地已配置 `psql` 可执行命令。
+
+## 使用方法
+
+```powershell
+cd deploy/postgres
+.\bootstrap.ps1 `
+  -Host 120.53.222.17 `
+  -Port 5432 `
+  -AdminUser postgres `
+  -AdminPassword "超级管理员密码"
+```
+
+脚本会：
+
+1. 创建/更新以下角色与库：
+   - `app_user` / `takeout_app_db`
+   - `identity_user` / `takeout_identity_db`
+   - `dictionary_user` / `takeout_dictionary_db`
+   - `hangfire_user` / `takeout_hangfire_db`
+2. 为库设置 COMMENT，授予 Schema `public` 的 CRUD 权限。
+3. 输出执行日志，失败时终止。
+
+## 自定义
+
+- 如需修改密码或新增库，编辑 `create_databases.sql` 后重新运行脚本。
+- 若在本地拉起测试库，可把 `Host` 指向 `localhost`，其余参数保持一致。
+
+## 常见问题
+
+| 问题 | 处理方式 |
+| --- | --- |
+| `psql : command not found` | 确认 PostgreSQL bin 目录已加入 PATH。 |
+| `permission denied to create database` | 改用具有 `CREATEDB` 权限的管理员执行脚本。 |
+| 需要删除库 | 先 `DROP DATABASE xxx`，再运行脚本重新创建。 |

+# Redis 部署脚本
+
+本目录提供可复用的 Redis 配置，既可在本地通过 Docker Compose 启动，也可将 `redis.conf` 拷贝到现有服务器，确保与线上一致。
+
+## 1. 部署步骤 (裸机)\n\n1. 将 \\
edis.conf\\ 拷贝到服务器（例如 /etc/redis/redis.conf）。\n2. 根据需要修改数据目录（\\dir\\）和绑定地址。\n3. 使用系统服务或 \\
edis-server redis.conf\\ 启动。\n4. 确认开放端口 6379，保证通过 \\
edis-cli -h <host> -a <pwd> ping\\ 可访问。\n\n## 2. 配置说明\n\n- \\
equirepass\\ 已设置为 MsuMshk112233。\n- 启用 appendonly（AOF），并每秒 fsync。\n- \\maxmemory-policy\\ 为 allkeys-lru，适合缓存场景。\n- \\protected-mode no\\ 允许远程连接，需结合安全组或防火墙限制来源 IP。\n\n## 3. 常用命令使用 `redis.conf`
+
+1. 把 `redis.conf` 拷贝到服务器 `/etc/redis/redis.conf`（或自定义目录）。
+2. 修改 `dir` 指向实际数据目录。
+3. 使用系统服务或 `redis-server redis.conf` 启动。
+
+关键配置已包含：
+
+- `requirepass`（密码）
+- `protected-mode no`（允许远程连接）
+- `appendonly yes` + `appendfsync everysec`
+- `maxmemory-policy allkeys-lru`
+
+## 3. 常用命令
+
+在应用或 CLI 中使用：
+
+```bash
+redis-cli -h 49.232.6.45 -p 6379 -a MsuMshk112233 ping
+```
+
+`appsettings.*.json` 的格式：`"Redis": "49.232.6.45:6379,password=MsuMshk112233,abortConnect=false"`
+
+## 4. 备份
+
+- RDB 文件：`dump.rdb`
+- AOF 文件：`appendonly.aof`
+
+通过 `redis-cli -a <pwd> save` 或 `bgsave` 触发。确保备份目录已纳入快照/对象存储。
