|
||
|
||
## 第一部分:北京 VPS 配置
|
||
|
||
### 1.1 Nginx Stream SNI 分流 `beijing-vps-stream.conf`
|
||
|
||
新增 `news.apple.com` SNI 映射(用于旁路由 Mihomo 直连代理):
|
||
|
||
```nginx
|
||
stream {
|
||
map $ssl_preread_server_name $backend {
|
||
www.apple.com xray; # 旁路由反向代理隧道
|
||
www.microsoft.com mihomo; # 外部客户端代理 → 东京出口
|
||
news.apple.com xray_lan; # 旁路由 Mihomo 北京直连代理
|
||
drive.salmonstill.cn nas; # 绿联云服务
|
||
default npm; # Nginx Proxy Manager
|
||
}
|
||
upstream xray { server 127.0.0.1:9443; }
|
||
upstream mihomo { server 127.0.0.1:9444; }
|
||
upstream xray_lan { server 127.0.0.1:9445; } # 新增
|
||
upstream nas { server 127.0.0.1:38653; }
|
||
upstream npm { server 127.0.0.1:8443; }
|
||
|
||
server {
|
||
listen 443 reuseport;
|
||
listen [::]:443 reuseport;
|
||
ssl_preread on;
|
||
proxy_pass $backend;
|
||
}
|
||
}
|
||
```
|
||
|
||
### 1.2 Xray 配置 `xray-北京vps-config.json`
|
||
|
||
#### 新增入站 `proxy_from_lan`(北京直连出口)
|
||
|
||
```json
|
||
{
|
||
"tag": "proxy_from_lan",
|
||
"listen": "127.0.0.1",
|
||
"port": 9445,
|
||
"protocol": "vless",
|
||
"settings": {
|
||
"clients": [
|
||
{
|
||
"id": "113e167a-a2be-4b46-9010-60020108626c",
|
||
"flow": "xtls-rprx-vision"
|
||
}
|
||
],
|
||
"decryption": "none"
|
||
},
|
||
"streamSettings": {
|
||
"network": "raw",
|
||
"security": "reality",
|
||
"realitySettings": {
|
||
"show": false,
|
||
"target": "www.apple.com:443",
|
||
"serverNames": ["news.apple.com"],
|
||
"privateKey": "GGT9LfN_2JdQG68cwrULgUK-adfT6wIokLzWjaB0fXs",
|
||
"shortIds": ["7c947a71b94f369e"]
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
> Reality 公私钥复用已有的 `interconn` 入站 keypair,`serverNames` 用新的 `news.apple.com` 与 Nginx 对应。
|
||
> `target` 设为 `www.apple.com:443`,Reality 从此地址偷取真实 TLS 证书用于伪装。
|
||
|
||
#### 新增入站 `external_qbit`(BT 入站端口)
|
||
|
||
```json
|
||
{
|
||
"tag": "external_qbit",
|
||
"listen": "0.0.0.0",
|
||
"port": 51413,
|
||
"protocol": "dokodemo-door",
|
||
"settings": {
|
||
"address": "127.0.0.1",
|
||
"port": 51413,
|
||
"network": "tcp"
|
||
}
|
||
}
|
||
```
|
||
|
||
> 仅 TCP——Xray portal 反向代理对 UDP 支持不完善,BT 的 μTP(UDP) 走不了,需要在 qBittorrent 里关闭。
|
||
|
||
#### 新增路由规则
|
||
|
||
```json
|
||
{ "type": "field", "inboundTag": ["proxy_from_lan"], "outboundTag": "direct" },
|
||
{ "type": "field", "inboundTag": ["external_qbit"], "outboundTag": "portal" }
|
||
```
|
||
|
||
### 1.3 腾讯云防火墙
|
||
|
||
新开端口:
|
||
|
||
| 端口 | 协议 | 用途 |
|
||
|---|---|---|
|
||
| 51413 | TCP | BT 入站 |
|
||
|
||
---
|
||
|
||
## 第二部分:旁路由 Xray SOCKS5 出站代理
|
||
|
||
### 2.1 配置 `xray-旁路由-config.json`
|
||
|
||
qBittorrent 出站不走 Mihomo 透明代理,而是通过旁路由上 Xray 的 `socks-lan` 入站(`:1080`),直接转发到北京 VPS 直连出口。
|
||
|
||
#### SOCKS5 入站
|
||
|
||
```json
|
||
{
|
||
"tag": "socks-lan",
|
||
"port": 1080,
|
||
"listen": "0.0.0.0",
|
||
"protocol": "socks",
|
||
"settings": {
|
||
"auth": "noauth",
|
||
"udp": true
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 出站 `to_beijing_direct`
|
||
|
||
```json
|
||
{
|
||
"tag": "to_beijing_direct",
|
||
"protocol": "vless",
|
||
"settings": {
|
||
"vnext": [
|
||
{
|
||
"address": "salmonstill.cn",
|
||
"port": 443,
|
||
"users": [
|
||
{
|
||
"id": "113e167a-a2be-4b46-9010-60020108626c",
|
||
"flow": "xtls-rprx-vision",
|
||
"encryption": "none"
|
||
}
|
||
]
|
||
}
|
||
]
|
||
},
|
||
"streamSettings": {
|
||
"network": "raw",
|
||
"security": "reality",
|
||
"realitySettings": {
|
||
"fingerprint": "chrome",
|
||
"serverName": "news.apple.com",
|
||
"publicKey": "62y5gDjPrdeuePGl-D2IW4Cw9Kb8_bSBBTmArvL7Nhs",
|
||
"shortId": "7c947a71b94f369e"
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 路由规则
|
||
|
||
```json
|
||
{ "type": "field", "inboundTag": ["socks-lan"], "outboundTag": "to_beijing_direct" }
|
||
```
|
||
|
||
> 路径:`qBittorrent → SOCKS5 旁路由:1080 → to_beijing_direct → 北京VPS:443(SNI=news.apple.com) → proxy_from_lan:9445 → direct → 互联网`
|
||
|
||
---
|
||
|
||
## 第三部分:旁路由 Xray 51413 转发
|
||
|
||
### 3.1 配置 `xray-旁路由-config.json`
|
||
|
||
#### 新增加出站 `to_qbit`
|
||
|
||
```json
|
||
{
|
||
"tag": "to_qbit",
|
||
"protocol": "freedom",
|
||
"settings": {
|
||
"redirect": "192.168.1.200:51413"
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 新增路由规则
|
||
|
||
```json
|
||
{
|
||
"type": "field",
|
||
"inboundTag": ["bridge"],
|
||
"port": "51413",
|
||
"outboundTag": "to_qbit"
|
||
}
|
||
```
|
||
|
||
> 放在 bridge 下——从北京 VPS 的 portal 通过反向隧道过来的 BT 入站流量,由 bridge 接收后按端口 51413 匹配到此规则,转发到 qBittorrent 容器。
|
||
|
||
---
|
||
|
||
## 第四部分:NAS qBittorrent Docker
|
||
|
||
### 4.1 创建 macvlan 网络
|
||
|
||
```bash
|
||
docker network create -d macvlan \
|
||
--subnet=192.168.1.0/24 \
|
||
--gateway=192.168.1.199 \
|
||
--ip-range=192.168.1.200/32 \
|
||
-o parent=eth0 \
|
||
qbit_macvlan
|
||
```
|
||
|
||
> `--gateway=192.168.1.199`:qBittorrent 的默认网关设为旁路由,确保出站流量经过旁路由。
|
||
> `--ip-range=192.168.1.200/32`:固定 IP。
|
||
|
||
### 4.2 启动容器
|
||
|
||
```bash
|
||
docker run -d \
|
||
--name qbittorrent \
|
||
--network qbit_macvlan \
|
||
--ip 192.168.1.200 \
|
||
-e WEBUI_PORT=8090 \
|
||
-p 8090:8090 \
|
||
-v /path/to/downloads:/downloads \
|
||
lscr.io/linuxserver/qbittorrent:latest
|
||
```
|
||
|
||
### 4.3 qBittorrent 设置
|
||
|
||
| 设置项 | 值 |
|
||
|---|---|
|
||
| 监听端口 | `51413` |
|
||
| UPnP/NAT-PMP | **禁用** |
|
||
| SOCKS5 代理 | `192.168.1.199` / 端口 `1080` |
|
||
| 连接协议 | **仅 TCP**(关闭 μTP) |
|
||
| DHT | 可选(建议开) |
|
||
| PEX | 可选(建议开) |
|
||
|
||
> 关闭 μTP(UDP):Xray portal 反向代理不支持 UDP,BT 的 μTP 走 UDP 会导致入站失败。
|
||
|
||
### 4.4 定时做种调度(crontab)
|
||
|
||
让 qBittorrent 只在夜间(01:00-07:00)做种,白天暂停以节省带宽:
|
||
|
||
```bash
|
||
crontab -e
|
||
```
|
||
|
||
添加以下两行(在 NAS 或任意可访问 192.168.1.200 的设备上):
|
||
|
||
```
|
||
0 1 * * * curl -s -X POST "http://192.168.1.200:8888/api/v2/torrents/start" --data "hashes=all"
|
||
0 7 * * * curl -s -X POST "http://192.168.1.200:8888/api/v2/torrents/stop" --data "hashes=all"
|
||
```
|
||
|
||
| 时间 | 操作 | 含义 |
|
||
|---|---|---|
|
||
| 凌晨 01:00 | `/torrents/start` `hashes=all` | 启动全部种子开始做种 |
|
||
| 早上 07:00 | `/torrents/stop` `hashes=all` | 停止全部种子 |
|
||
|
||
---
|
||
|
||
## 第五部分:部署顺序
|
||
|
||
```
|
||
1. 腾讯云防火墙 → 开放 51413/tcp
|
||
2. scp beijing-vps-stream.conf → 北京VPS /etc/nginx/stream.conf.d/
|
||
3. scp xray-北京vps-config.json → 北京VPS /usr/local/etc/xray/config.json
|
||
4. 北京VPS: nginx -t && systemctl reload nginx
|
||
5. 北京VPS: systemctl restart xray
|
||
6. scp 旁路由的mihomo config.yaml → 旁路由 /opt/mihomo/config.yaml
|
||
7. scp xray-旁路由-config.json → 旁路由 /etc/xray/config.json
|
||
8. 旁路由: /etc/init.d/mihomo restart
|
||
9. 旁路由: /etc/init.d/xray restart
|
||
10. NAS: 创建 macvlan 网络 + 启动 qBittorrent 容器
|
||
11. NAS: 配置 qBittorrent 监听端口 51413,关闭 μTP
|
||
```
|
||
|
||
---
|
||
|
||
## 第六部分:验证
|
||
|
||
### 6.1 SOCKS5 代理出站验证
|
||
|
||
```bash
|
||
# 在 NAS 上执行,应返回北京 VPS 的公网 IP
|
||
docker exec qbittorrent curl --socks5 192.168.1.199:1080 https://ip.sb
|
||
```
|
||
|
||
### 6.2 Xray 日志确认
|
||
|
||
```bash
|
||
# 旁路由上查看 Xray 日志,确认 socks-lan 流量转发正常
|
||
tail -f /var/log/xray.log | grep socks-lan
|
||
```
|
||
|
||
### 6.3 BT 入站验证
|
||
|
||
```bash
|
||
# 北京 VPS 上确认端口监听
|
||
ss -tlnp | grep 51413
|
||
|
||
# 从外部测试端口可达
|
||
nc -zv salmonstill.cn 51413
|
||
```
|
||
|
||
### 6.4 端到端 BT 测试
|
||
|
||
下载一个热门 Ubuntu torrent 种子,观察:
|
||
- qBittorrent WebUI → 连接 → 应显示 DHT 节点数增长
|
||
- 跟踪器页面 → 应显示 "Working"
|
||
- 下载速度应有上传来确认入站工作
|
||
|
||
---
|
||
|
||
## 第七部分:故障排查
|
||
|
||
| 现象 | 排查 |
|
||
|---|---|
|
||
| qBittorrent curl ip.sb 返回真实 IP | SOCKS5 代理未生效,检查 qBittorrent 设置中代理配置 |
|
||
| 代理连不上 | 确认 旁路由 Xray 正在运行且 `socks-lan` 入站监听 :1080 |
|
||
| 入站无上传 | 检查北京 VPS ufw/腾讯云安全组已放行 51413/tcp |
|
||
| xray 报错 `reverse-proxy.xray.internal` | portal/bridge 域名不匹配,两边必须一致 |
|
||
| 下载有速度、无上传 | μTP 没关或 portal UDP 不支持,qBittorrent 设置仅 TCP |
|
||
|
||
---
|
||
|
||
## 第八部分:文件清单
|
||
|
||
| 文件 | 位置 | 作用 |
|
||
|---|---|---|
|
||
| `beijing-vps-stream.conf` | 北京VPS `/etc/nginx/stream.conf.d/` | Nginx SNI分流(含 news.apple.com → 9445) |
|
||
| `xray-北京vps-config.json` | 北京VPS `/usr/local/etc/xray/config.json` | Xray 入站+路由(含 proxy_from_lan + external_qbit) |
|
||
| `xray-旁路由-config.json` | 旁路由 `/etc/xray/config.json` | Xray bridge + to_qbit(51413) + socks-lan(1080) → to_beijing_direct |
|
