+# sing-box Xboard Fork
 
----
+这是一个基于上游 [SagerNet/sing-box](https://github.com/SagerNet/sing-box) 的定制分支，主要面向 Xboard / UniProxy 面板联动部署场景。
 
-# sing-box
+它保留了上游 `sing-box` 内核能力，同时补充了：
 
-The universal proxy platform.
+- Xboard 动态入站服务
+- 多节点托管
+- 面板协议自动识别
+- VLESS / REALITY 面板字段映射
+- Shadowsocks 2022 用户同步与密钥处理
+- AnyTLS / Trojan / Hysteria / TUIC 的本地 TLS / ACME 支持
+- 安装脚本与分离式配置模板
+- PROXY protocol 客户端真实 IP 传递
 
-## Repository Notice
+如果你要查看官方功能基线、通用配置文档、原始内核行为，请优先参考上游：
 
-This repository is a customized fork based on the upstream [SagerNet/sing-box](https://github.com/SagerNet/sing-box) project.
+- 上游仓库：https://github.com/SagerNet/sing-box
+- 上游文档：https://sing-box.sagernet.org
 
-- Upstream project: `sing-box`
-- Upstream documentation: https://sing-box.sagernet.org
-- This repository may contain local modifications for Xboard integration, deployment scripts, and protocol handling behavior
+## 适用场景
 
-If you are looking for the official project, feature baseline, or upstream release notes, please refer to the upstream `sing-box` repository first.
+这个仓库更适合以下用途：
 
-[![Packaging status](https://repology.org/badge/vertical-allrepos/sing-box.svg)](https://repology.org/project/sing-box/versions)
+- 从 Xboard / UniProxy 面板拉取节点配置
+- 从面板拉取用户并动态更新
+- 单机运行多个节点
+- 给面板型机场节点准备安装脚本
+- 对接面板下发的 `protocol`、`cert_config`、`accept_proxy_protocol`、REALITY 字段等
 
-## Documentation
+## 主要特性
 
-https://sing-box.sagernet.org
+- `services.xboard` 动态服务
+- 支持单节点和多节点
+- 协议优先从面板返回的 `protocol` 识别
+- 支持面板回包控制 `accept_proxy_protocol`
+- 支持 VLESS REALITY 的 `server_name`、`public_key`、`private_key`、`short_id`
+- 支持 ACME：
+  - `auto_tls`
+  - `cert_mode = http`
+  - `cert_mode = dns`
+- 当前已支持的 ACME DNS provider：
+  - `cloudflare`
+  - `alidns`
+  - `tencentcloud`
+  - `dnspod`
+  - `acmedns`
+- 安装脚本默认生成：
+  - `/etc/sing-box/config.d/10-base.json`
+  - `/etc/sing-box/config.d/20-outbounds.json`
+- 安装后的服务名为：
+  - `singbox.service`
+
+## 仓库内关键文件
+
+- [install.sh](./install.sh)
+  Linux 安装脚本
+- [option/xboard.go](./option/xboard.go)
+  `services.xboard` 配置结构
+- [service/xboard/service.go](./service/xboard/service.go)
+  Xboard 动态服务实现
+- [configs](./configs)
+  配置示例目录
+
+## 快速开始
+
+### 1. 编译并安装
+
+在 Linux 服务器上进入仓库目录：
+
+```bash
+chmod +x install.sh
+./install.sh
+```
+
+脚本会做这些事情：
+
+1. 检查 Go 环境
+2. 编译当前仓库代码
+3. 生成分离配置
+4. 创建 `singbox.service`
+5. 启动服务
+
+### 2. 安装过程会询问的内容
+
+- `Panel URL`
+- `Panel Token`
+- 一个或多个 `Node ID`
+- DNS 模式：
+  - `udp`
+  - `local`
+- 当前节点前面是否有发送 PROXY protocol 的四层代理
+
+### 3. 多节点输入规则
+
+- 安装脚本会持续要求输入 `Node ID`
+- 输入 `NO` 才结束
+- 至少要有一个节点
+
+## 运行与管理
+
+查看状态：
+
+```bash
+systemctl status singbox
+```
+
+查看日志：
+
+```bash
+journalctl -u singbox -f
+```
+
+重启服务：
+
+```bash
+systemctl restart singbox
+```
+
+手动运行：
+
+```bash
+sing-box -D /var/lib/sing-box -C /etc/sing-box/config.d run
+```
+
+## 推荐配置结构
+
+建议把配置拆成两部分。
+
+### `10-base.json`
+
+放这些内容：
+
+- 日志
+- DNS
+- `services`
+- 基础路由规则
+
+### `20-outbounds.json`
+
+放这些内容：
+
+- 全部出站
+- 出站标签
+- 你自己的分流依赖
+
+这样更方便：
+
+- 面板动态服务和你的自定义出站分离
+- 安装脚本生成的基础配置不容易被误改
+- 调整出站时不会影响 Xboard 服务主体
+
+示例已放在：
+
+- [configs/10-base.single-node.json](./configs/10-base.single-node.json)
+- [configs/10-base.multi-node.json](./configs/10-base.multi-node.json)
+- [configs/20-outbounds.example.json](./configs/20-outbounds.example.json)
+
+## `services.xboard` 配置说明
+
+配置结构定义见 [option/xboard.go](./option/xboard.go)。
+
+### 最小单节点示例
+
+```json
+{
+  "type": "xboard",
+  "panel_url": "https://panel.example.com",
+  "key": "replace-with-node-token",
+  "sync_interval": "1m",
+  "report_interval": "1m",
+  "node_id": 286
+}
+```
+
+### 多节点示例
+
+```json
+{
+  "type": "xboard",
+  "panel_url": "https://panel.example.com",
+  "key": "replace-with-node-token",
+  "sync_interval": "1m",
+  "report_interval": "1m",
+  "nodes": [
+    {
+      "node_id": 286
+    },
+    {
+      "node_id": 774
+    }
+  ]
+}
+```
+
+### 当前推荐做法
+
+- 只传 `panel_url`
+- 只传 `key`
+- 只传 `node_id` 或 `nodes`
+
+下面这些字段仍然保留兼容，但常规部署一般不需要：
+
+- `config_panel_url`
+- `user_panel_url`
+- `config_node_id`
+- `user_node_id`
+- `node_type`
+
+说明：
+
+- 当前逻辑会优先从面板回包中的 `protocol` 自动识别协议
+- `node_type` 更适合做历史兼容，不建议再依赖它做主配置
+
+## 面板配置回包约定
+
+### 1. 协议识别
+
+推荐面板显式返回：
+
+```json
+{
+  "protocol": "vless"
+}
+```
+
+当前服务会按如下顺序识别协议：
+
+1. `protocol`
+2. `node_type`
+3. 如果是 Shadowsocks 且存在 `cipher`，则回退识别为 `shadowsocks`
+
+### 2. 监听地址与端口
+
+推荐面板返回：
+
+```json
+{
+  "listen_ip": "0.0.0.0",
+  "server_port": 443
+}
+```
+
+### 3. PROXY protocol
+
+如果前面有四层代理，并且它会发送 PROXY protocol 头，需要面板返回：
+
+```json
+{
+  "accept_proxy_protocol": true
+}
+```
+
+如果用户是直连节点，不要开启这个字段，否则连接会失败。
+
+### 4. VLESS REALITY
+
+当前支持从面板获取这些字段：
+
+- `tls_settings.server_name`
+- `tls_settings.public_key`
+- `tls_settings.private_key`
+- `tls_settings.short_id`
+- 顶层 `server_name`
+- 顶层 `public_key`
+- 顶层 `private_key`
+- 顶层 `short_id`
+
+示例见：
+
+- [configs/panel-response.vless-reality.json](./configs/panel-response.vless-reality.json)
+
+### 5. Shadowsocks 2022
+
+推荐面板返回：
+
+- `protocol: "shadowsocks"`
+- `cipher`
+- `server_key`
+
+示例见：
+
+- [configs/panel-response.shadowsocks2022.json](./configs/panel-response.shadowsocks2022.json)
+
+### 6. AnyTLS / Trojan / Hysteria / TUIC 的证书要求
+
+这些协议通常要求本地具备可用 TLS 证书。当前支持：
+
+- 文件证书
+- 证书内容直传
+- ACME 自动签发
+
+如果面板没有下发可用证书，也没有有效 ACME 配置，常见报错是：
+
+```text
+Xboard setup error: missing certificate
+```
+
+示例见：
+
+- [configs/panel-response.anytls-acme-dns.json](./configs/panel-response.anytls-acme-dns.json)
+
+## ACME 说明
+
+当前支持：
+
+- `auto_tls: true`
+- `cert_mode: "http"`
+- `cert_mode: "dns"`
+
+### DNS-01 provider
+
+已支持：
+
+- `cloudflare`
+- `alidns`
+- `tencentcloud`
+- `dnspod`
+- `acmedns`
+
+### DNSPod 说明
+
+仓库已经内置 DNSPod provider 适配，不再依赖旧版 `github.com/libdns/dnspod` 的接口兼容。
+
+你可以从面板下发：
+
+```json
+{
+  "cert_config": {
+    "cert_mode": "dns",
+    "dns_provider": "dnspod",
+    "dns_env": {
+      "DNSPOD_TOKEN": "id,token"
+    }
+  }
+}
+```
+
+也可以下发腾讯云凭据：
+
+```json
+{
+  "cert_config": {
+    "cert_mode": "dns",
+    "dns_provider": "tencentcloud",
+    "dns_env": {
+      "TENCENTCLOUD_SECRET_ID": "xxx",
+      "TENCENTCLOUD_SECRET_KEY": "xxx"
+    }
+  }
+}
+```
+
+## 配置示例目录
+
+[configs](./configs) 目录中已经提供了这些示例：
+
+- [configs/10-base.single-node.json](./configs/10-base.single-node.json)
+  单节点基础配置
+- [configs/10-base.multi-node.json](./configs/10-base.multi-node.json)
+  多节点基础配置
+- [configs/20-outbounds.example.json](./configs/20-outbounds.example.json)
+  出站配置模板
+- [configs/panel-response.vless-reality.json](./configs/panel-response.vless-reality.json)
+  VLESS REALITY 面板回包
+- [configs/panel-response.shadowsocks2022.json](./configs/panel-response.shadowsocks2022.json)
+  Shadowsocks 2022 面板回包
+- [configs/panel-response.anytls-acme-dns.json](./configs/panel-response.anytls-acme-dns.json)
+  AnyTLS + ACME DNS 验证面板回包
+
+## 常见问题
+
+### `unsupported protocol: empty`
+
+原因通常是：
+
+- 面板没有返回 `protocol`
+- 兼容字段 `node_type` 也为空
+
+建议：
+
+- 面板显式返回顶层 `protocol`
+
+### `Xboard setup error: missing certificate`
+
+原因通常是：
+
+- AnyTLS / Trojan / Hysteria / TUIC 需要证书
+- 面板没有下发证书文件、证书内容或 ACME 参数
+
+### `TLS handshake: REALITY: processed invalid connection`
+
+多数情况下表示客户端参数和当前 REALITY 节点配置不匹配，例如：
+
+- `server_name` 错误
+- `public_key` 错误
+- `short_id` 错误
+- 客户端实际上不是按 REALITY 模式连入
+
+### `Server does not exist`
+
+通常是：
+
+- 面板里不存在该 `node_id`
+- `token` 不匹配
+- 拉取配置或拉取用户的节点 ID 写错
+
+### 真实 IP 没有正确获取
+
+请确认：
+
+1. 前置代理确实发送了 PROXY protocol
+2. 面板确实下发了 `accept_proxy_protocol: true`
+
+否则服务只能看到上游代理 IP。
+
+## 开发验证
+
+近期已验证通过的命令：
+
+```bash
+go test ./common/dnspod ./common/tls ./service/acme ./service/xboard
+go build -trimpath -tags 'with_quic,with_utls,with_clash_api,with_gvisor,with_acme' ./cmd/sing-box
+```
+
+如果你改动了 Xboard、协议映射、ACME 或证书相关逻辑，建议至少执行一次以上命令。
