+#### PostgreSQL 部署（Docker Compose）
+
+安装脚本会根据环境自动下载对应的 Compose 配置并保存为 `docker-compose.yml`。默认仍使用 SQLite，切换到 PostgreSQL 只需要配置环境变量。
+
+1) 在 `docker-compose` 同目录创建或修改 `.env`：
+
+```bash
+JWT_SECRET=replace_with_your_secret
+BACKEND_PORT=6365
+FRONTEND_PORT=6366
+
+DB_TYPE=postgres
+DATABASE_URL=postgres://flux_panel:replace_with_strong_password@postgres:5432/flux_panel?sslmode=disable
+
+POSTGRES_DB=flux_panel
+POSTGRES_USER=flux_panel
+POSTGRES_PASSWORD=replace_with_strong_password
+```
+
+> 📌 使用安装脚本部署时，`POSTGRES_PASSWORD` 会自动随机生成并写入 `.env`。
+
+2) 启动服务：
+
+```bash
+docker compose up -d
+```
+
+3) 如果你想继续使用 SQLite，保留 `DB_TYPE=sqlite`（或不设置 `DB_TYPE`）即可。
+
+#### 从 SQLite 迁移到 PostgreSQL
+
+如果你是通过 `panel_install.sh` 安装面板，推荐直接使用脚本菜单一键迁移：
+
+```bash
+./panel_install.sh
+# 选择 4. 迁移到 PostgreSQL
+```
+
+脚本会自动完成 SQLite 备份、PostgreSQL 启动、`pgloader` 导入、`.env` 中 `DB_TYPE`/`DATABASE_URL` 更新，并重启服务。
+
+如果你希望手动迁移，以下示例基于 Docker Volume `sqlite_data`（项目默认配置）与 `pgloader`：
+
+1) 停止服务并备份 SQLite 数据：
+
+```bash
+docker compose down
+docker run --rm -v sqlite_data:/data -v "$(pwd)":/backup alpine sh -c "cp /data/gost.db /backup/gost.db.bak"
+```
+
+2) 仅启动 PostgreSQL：
+
+```bash
+docker compose up -d postgres
+```
+
+3) 使用 `pgloader` 迁移：
+
+```bash
+source .env
+docker run --rm --network gost-network -v sqlite_data:/sqlite dimitri/pgloader:latest pgloader /sqlite/gost.db "postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}"
+```
+
+4) 切换后端到 PostgreSQL 并启动：
+
+```bash
+source .env
+export DB_TYPE=postgres
+export DATABASE_URL="postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}?sslmode=disable"
+docker compose up -d
+```
+
+5) 迁移完成后，登录面板检查用户、隧道、转发、节点数据是否正确。

+# PostgreSQL 数据库指南
+
+FLVX 默认使用 SQLite 作为数据库，同时也内置了对 PostgreSQL 的完整支持。本文档介绍如何使用 PostgreSQL 部署面板、从 SQLite 迁移以及日常维护。
+
+## 一、SQLite 与 PostgreSQL 对比
+
+| 特性 | SQLite | PostgreSQL |
+|------|--------|------------|
+| **部署复杂度** | 零配置，开箱即用 | 需要额外的数据库服务 |
+| **并发性能** | 适合小规模单机使用 | 支持高并发读写 |
+| **数据规模** | 适合中小规模数据 | 适合大规模数据 |
+| **备份与恢复** | 直接复制文件 | 支持逻辑备份与物理备份 |
+| **高可用** | 不支持 | 支持主从复制、流复制 |
+
+**建议**：如果你只是个人使用或小团队使用，SQLite 完全够用。如果节点多，推荐使用 PostgreSQL。
+
+---
+
+## 二、环境变量说明
+
+以下环境变量用于配置数据库连接，在 `.env` 文件或 Docker Compose `environment` 中设置。
+
+### 后端服务 (backend) 使用
+
+| 变量名 | 说明 | 默认值 | 示例 |
+|--------|------|--------|------|
+| `DB_TYPE` | 数据库类型，`sqlite` 或 `postgres` | `sqlite` | `postgres` |
+| `DATABASE_URL` | PostgreSQL 连接字符串（仅 `DB_TYPE=postgres` 时必填） | 空 | `postgres://flux_panel:密码@postgres:5432/flux_panel?sslmode=disable` |
+| `DB_PATH` | SQLite 数据库文件路径（仅 `DB_TYPE=sqlite` 时使用） | `/app/data/gost.db` | `/app/data/gost.db` |
+
+### PostgreSQL 容器使用
+
+| 变量名 | 说明 | 默认值 |
+|--------|------|--------|
+| `POSTGRES_DB` | 数据库名称 | `flux_panel` |
+| `POSTGRES_USER` | 数据库用户名 | `flux_panel` |
+| `POSTGRES_PASSWORD` | 数据库密码 | `flux_panel_change_me` |
+
+> ⚠️ **安全提示**：生产环境中请务必修改 `POSTGRES_PASSWORD` 为强密码，不要使用默认值！
+
+---
+
+## 三、全新部署（Docker Compose + PostgreSQL）
+
+安装脚本会根据环境自动下载对应的 Compose 配置并保存为 `docker-compose.yml`。默认使用 SQLite，只需配置环境变量即可切换到 PostgreSQL。
+
+### 1. 创建 `.env` 文件
+
+在 `docker-compose` 同目录创建 `.env` 文件：
+
+```bash
+# 基础配置
+JWT_SECRET=替换为你的密钥
+BACKEND_PORT=6365
+FRONTEND_PORT=6366
+
+# PostgreSQL 配置
+DB_TYPE=postgres
+DATABASE_URL=postgres://flux_panel:替换为强密码@postgres:5432/flux_panel?sslmode=disable
+
+POSTGRES_DB=flux_panel
+POSTGRES_USER=flux_panel
+POSTGRES_PASSWORD=替换为强密码
+```
+
+> ⚠️ `DATABASE_URL` 中的密码必须与 `POSTGRES_PASSWORD` 保持一致。
+
+### 2. 启动服务
+
+```bash
+docker compose up -d
+```
+
+### 3. 验证
+
+```bash
+# 检查所有容器是否正常运行
+docker ps
+
+# 查看后端日志，确认连接 PostgreSQL 成功
+docker logs flux-panel-backend
+
+# 查看 PostgreSQL 容器状态
+docker logs flux-panel-postgres
+```
+
+---
+
+## 四、从 SQLite 迁移到 PostgreSQL
+
+如果你已经在使用 SQLite 并且希望迁移到 PostgreSQL，请按照以下步骤操作。
+
+### 快速方式：脚本菜单一键迁移（推荐）
+
+如果你是通过安装脚本部署面板，可直接执行：
+
+```bash
+./panel_install.sh
+# 选择 4. 迁移到 PostgreSQL
+```
+
+脚本会自动完成以下操作：
+- 备份 SQLite 数据到当前目录（`gost.db.bak`）
+- 启动并等待 PostgreSQL 健康检查通过
+- 使用 `pgloader` 导入 SQLite 数据
+- 自动写入 `.env` 的 `DB_TYPE=postgres` 与 `DATABASE_URL`
+- 重启服务并等待后端健康检查
+
+### 手动方式：按步骤迁移
+
+### 1. 备份 SQLite 数据
+
+```bash
+# 停止所有服务
+docker compose down
+
+# 备份 SQLite 数据文件到当前目录
+docker run --rm -v sqlite_data:/data -v "$(pwd)":/backup alpine sh -c "cp /data/gost.db /backup/gost.db.bak"
+```
+
+### 2. 配置 PostgreSQL 环境变量
+
+在 `.env` 文件中添加 PostgreSQL 配置（参考上方"环境变量说明"）。
+
+### 3. 仅启动 PostgreSQL
+
+```bash
+docker compose up -d postgres
+```
+
+等待 PostgreSQL 完全就绪：
+
+```bash
+# 检查 PostgreSQL 健康状态
+docker inspect --format='{{.State.Health.Status}}' flux-panel-postgres
+# 输出 "healthy" 表示就绪
+```
+
+### 4. 使用 pgloader 迁移数据
+
+```bash
+source .env
+docker run --rm \
+  --network gost-network \
+  -v sqlite_data:/sqlite \
+  dimitri/pgloader:latest \
+  pgloader /sqlite/gost.db "postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}"
+```
+
+> 📌 建议直接从 `.env` 读取 `POSTGRES_USER`、`POSTGRES_PASSWORD`、`POSTGRES_DB`，避免手填密码导致认证失败。
+
+### 5. 启动全部服务
+
+```bash
+source .env
+export DB_TYPE=postgres
+export DATABASE_URL="postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@postgres:5432/${POSTGRES_DB}?sslmode=disable"
+docker compose up -d
+```
+
+### 6. 验证迁移
+
+登录面板后，检查以下数据是否完整：
+- 用户列表和权限
+- 节点信息和状态
+- 隧道配置
+- 转发规则
+- 流量统计数据
+
+---
+
+## 五、独立 PostgreSQL（非 Docker）
+
+如果你不想使用 Docker Compose 中自带的 PostgreSQL 容器，也可以连接外部的 PostgreSQL 实例。
+
+### 1. 准备 PostgreSQL
+
+在目标 PostgreSQL 服务器上创建数据库和用户：
+
+```sql
+CREATE USER flux_panel WITH PASSWORD '你的强密码';
+CREATE DATABASE flux_panel OWNER flux_panel;
+```
+
+### 2. 配置连接
+
+修改 `.env` 文件，将 `DATABASE_URL` 指向外部 PostgreSQL：
+
+```bash
+DB_TYPE=postgres
+DATABASE_URL=postgres://flux_panel:你的强密码@数据库地址:5432/flux_panel?sslmode=disable
+```
+
+> 📌 如果 PostgreSQL 在远程服务器且启用了 SSL，请将 `sslmode=disable` 改为 `sslmode=require` 或 `sslmode=verify-full`。
+
+### 3. 停用内置 PostgreSQL 容器（可选）
+
+如果使用外部 PostgreSQL，可以在启动时不启动内置的 postgres 服务：
+
+```bash
+docker compose up -d backend frontend
+```
+
+---
+
+## 六、数据备份与恢复
+
+### 逻辑备份（pg_dump）
+
+```bash
+# 备份（在 Docker 环境下）
+docker exec flux-panel-postgres pg_dump -U flux_panel flux_panel > backup_$(date +%Y%m%d_%H%M%S).sql
+
+# 恢复
+docker exec -i flux-panel-postgres psql -U flux_panel flux_panel < backup_20260101_120000.sql
+```
+
+### 定时备份（cron）
+
+创建备份脚本 `/opt/flvx/backup.sh`：
+
+```bash
+#!/bin/bash
+BACKUP_DIR="/opt/flvx/backups"
+mkdir -p "$BACKUP_DIR"
+docker exec flux-panel-postgres pg_dump -U flux_panel flux_panel | gzip > "$BACKUP_DIR/flvx_$(date +%Y%m%d_%H%M%S).sql.gz"
+# 清理 30 天前的备份
+find "$BACKUP_DIR" -name "flvx_*.sql.gz" -mtime +30 -delete
+```
+
+添加 cron 任务（每天凌晨 3 点执行）：
+
+```bash
+chmod +x /opt/flvx/backup.sh
+echo "0 3 * * * /opt/flvx/backup.sh" | crontab -
+```
+
+---
+
+## 七、常见问题
+
+### Q: 切换到 PostgreSQL 后启动失败，提示连接被拒绝？
+
+**A**: 
+1. 确认 PostgreSQL 容器已启动并处于 `healthy` 状态：`docker ps`。
+2. 确认 `DATABASE_URL` 中的主机名、端口、用户名、密码正确。
+3. 在 Docker Compose 环境下，主机名应为 `postgres`（服务名），而非 `localhost`。
+
+### Q: pgloader 迁移时报错？
+
+**A**: 
+1. 确认 PostgreSQL 容器已完全就绪（状态为 `healthy`）。
+2. 确认 `--network gost-network` 参数正确，使 pgloader 容器与 PostgreSQL 在同一网络中。
+3. 如果数据库已有表结构，pgloader 可能会报冲突。可以先清空目标数据库后重试。
+
+### Q: 如何查看当前使用的数据库类型？
+
+**A**: 查看后端容器的 `DB_TYPE` 环境变量：
+
+```bash
+docker exec flux-panel-backend printenv DB_TYPE
+```
+
+### Q: 可以同时使用 SQLite 和 PostgreSQL 吗？
+
+**A**: 不可以。`DB_TYPE` 只能设置为 `sqlite` 或 `postgres` 之一。后端启动时根据此配置连接对应的数据库。
+
+### Q: PostgreSQL 数据存储在哪里？
+
+**A**: 在 Docker Compose 部署中，PostgreSQL 数据存储在名为 `postgres_data` 的 Docker Volume 中。可以通过以下命令查看：
+
+```bash
+docker volume inspect postgres_data
+```
