Official sing-box binaries lack v2ray_api, so drop that config and grpcio and track per-node traffic from Clash connection stats instead. Co-authored-by: Cursor <cursoragent@cursor.com>

# 运维与故障排查
|
||
|
||
## 服务检查
|
||
|
||
```bash
|
||
# sing-box 是否运行
|
||
systemctl is-active sing-box
|
||
|
||
# 管理面板是否运行
|
||
systemctl is-active jiedian-panel
|
||
|
||
# 配置语法
|
||
sing-box check -c /etc/sing-box/config.json
|
||
|
||
# 端口监听
|
||
ss -tlnp | grep 443 # Reality TCP
|
||
ss -tlnp | grep 5080 # 面板后端（仅本机）
|
||
ss -tlnp | grep :80 # Nginx（ACME + 面板反向代理）
|
||
ss -ulnp | grep 8443 # Hysteria2 UDP
|
||
|
||
# Nginx fallback
|
||
curl -s http://127.0.0.1:8080
|
||
```
|
||
|
||
## 管理面板访问
|
||
|
||
面板通过 **Nginx 80 端口反向代理**，不再单独暴露 8444。
|
||
|
||
```bash
|
||
# 查看面板路径（安装时自动生成或 .env 中配置）
|
||
grep PANEL_PATH /opt/jiedian/.env
|
||
|
||
# 示例：PANEL_PATH=jiedian-a1b2c3d4
|
||
# 访问地址：http://66.hyf2.cc/jiedian-a1b2c3d4/
|
||
curl -I "http://66.hyf2.cc/$(grep ^PANEL_PATH= /opt/jiedian/.env | cut -d= -f2)/login"
|
||
```
|
||
|
||
> 443 端口已被 sing-box Reality 占用，面板走 80 端口子路径。请妥善保管 `PANEL_PATH`，相当于隐藏入口。
|
||
|
||
面板可查看每个节点的 **在线状态、连接数、实时速率、累计流量**（数据来自 sing-box Clash API，仅监听 127.0.0.1）。
|
||
|
||
> **注意**：GitHub 官方 sing-box 预编译包**不含** `v2ray_api`，配置里不要启用 `experimental.v2ray_api`，否则 sing-box 无法启动。
|
||

|
||
|
||
## 常见问题
|
||
|
||
### sing-box 报错 v2ray api is not included in this build
|
||
|
||
GitHub 下载的官方 sing-box **默认不带** `v2ray_api` 模块。若配置里写了 `experimental.v2ray_api`，启动时会直接失败：
|
||
|
||
```
|
||
FATAL create v2ray-server: v2ray api is not included in this build, rebuild with -tags with_v2ray_api
|
||
```
|
||
|
||
**处理**：重新生成配置（已移除 v2ray_api，改用 Clash API 统计）并重启：
|
||
|
||
```bash
|
||
cd /opt/jiedian
|
||
git pull
|
||
python3 scripts/render-server.py
|
||
systemctl restart sing-box jiedian-panel
|
||
```
|
||
|
||
### 面板流量/在线状态显示「不可用」
|
||
|
||
sing-box Clash API 未就绪，按顺序检查：
|
||
|
||
```bash
|
||
systemctl is-active sing-box
|
||
ss -tlnp | grep 9090 # Clash API
|
||
grep CLASH_API_SECRET /opt/jiedian/.env
|
||
python3 /opt/jiedian/scripts/render-server.py
|
||
systemctl restart sing-box jiedian-panel
|
||
```
|
||
|
||
升级后若未重装，需重新生成 sing-box 配置并重启服务，才会启用 `experimental.clash_api`。
|
||
|
||
### 在线状态始终离线但客户端能连
|
||
|
||
- 有流量时面板会按速率推断在线；若仍显示离线，执行 `curl -s -H "Authorization: Bearer $(grep CLASH_API_SECRET /opt/jiedian/.env | cut -d= -f2)" http://127.0.0.1:9090/connections | head` 查看连接 metadata 是否含 user 字段
|
||
- 修改节点或升级后需重新渲染配置：`python3 /opt/jiedian/scripts/render-server.py && systemctl restart sing-box`
|
||
|
||
### 面板打不开 / 404
|
||
|
||
1. **路径不对**：必须用完整路径，末尾带 `/`，例如 `http://域名/jiedian-xxxx/login`
|
||
2. **Nginx 未加载配置**：
|
||
```bash
|
||
nginx -t && systemctl reload nginx
|
||
cat /etc/nginx/sites-available/acme | grep -A5 jiedian
|
||
```
|
||
3. **面板进程未运行**：
|
||
```bash
|
||
systemctl status jiedian-panel
|
||
journalctl -u jiedian-panel -n 30 --no-pager
|
||
curl -I http://127.0.0.1:5080/login
|
||
```
|
||
4. **阿里云安全组**：只需放行 `80/TCP`，**无需**再放行 8444
|
||
|
||
### 面板登录后跳回登录页 / 样式丢失
|
||
|
||
通常是子路径反向代理头未生效，检查 Nginx 是否包含：
|
||
|
||
```nginx
|
||
proxy_set_header X-Forwarded-Prefix /你的PANEL_PATH;
|
||
```
|
||
|
||
修改后 `systemctl reload nginx`，并确认 `.env` 中 `PANEL_PATH` 与 Nginx 一致。
|
||
|
||
### 设置了 PANEL_ALLOW_IP 后无法访问
|
||
|
||
`.env` 中 `PANEL_ALLOW_IP` 会限制仅该 IP 可访问面板。本机公网 IP 变更后需更新并重装 Nginx 配置：
|
||
|
||
```bash
|
||
# 编辑 .env 后重新渲染 nginx
|
||
cd /opt/jiedian
|
||
bash scripts/install.sh # 或手动 sed acme 配置后 reload nginx
|
||
```
|
||
|
||
### 忘记面板密码或路径
|
||
|
||
```bash
|
||
grep -E 'PANEL_(USERNAME|PASSWORD|PATH)' /opt/jiedian/.env
|
||
# 重置密码与 Reality 密钥
|
||
bash scripts/generate-keys.sh
|
||
```
|
||
|
||
### acme.sh 证书申请失败
|
||
|
||
```bash
|
||
# 确认 DNS 已生效
|
||
dig +short A your.domain.com
|
||
|
||
# 确认 80 端口未被占用（nginx 需先启动）
|
||
ss -tlnp | grep :80
|
||
|
||
# 手动重试
|
||
/root/.acme.sh/acme.sh --issue -d your.domain.com -w /var/www/acme --force
|
||
```
|
||
|
||
### sing-box 无法启动
|
||
|
||
```bash
|
||
journalctl -u sing-box -n 50 --no-pager
|
||
```
|
||
|
||
常见原因：证书路径错误、JSON 语法错误、443 被占用。
|
||
|
||
```bash
|
||
ss -tlnp | grep :443
|
||
sing-box check -c /etc/sing-box/config.json
|
||
```
|
||
|
||
### 客户端能连但速度慢
|
||
|
||
- 换 Hysteria2 节点（UDP/QUIC 抗丢包）
|
||
- 检查 VPS 带宽：`wget -O /dev/null http://speedtest.tele2.net/100MB.zip`
|
||
- 避免高峰时段长时间 4K 流媒体
|
||
|
||
### IP 被封
|
||
|
||
1. 向 VPS 商申请更换 IP
|
||
2. 修改 `.env` 中 `REALITY_SERVER_NAME` 为其他大站（如 `www.apple.com`）
|
||
3. 重新运行 `install.sh` 或手动更新 `/etc/sing-box/config.json` 并 restart
|
||
|
||
### apt 锁被占用
|
||
|
||
安装脚本会自动等待最多 10 分钟。若超时：
|
||
|
||
```bash
|
||
# 查看占用进程
|
||
fuser /var/lib/dpkg/lock-frontend
|
||
# 等待 cloud-init / unattended-upgrades 结束后再执行
|
||
bash scripts/install.sh
|
||
```
|
||
|
||
### SSH 主机密钥变更
|
||
|
||
VPS 重装系统后，本地执行：
|
||
|
||
```bash
|
||
ssh-keygen -R 你的VPS_IP
|
||
```
|
||
|
||
### 卸载后重装
|
||
|
||
```bash
|
||
cd /opt/jiedian
|
||
git pull
|
||
bash scripts/uninstall.sh
|
||
bash scripts/generate-keys.sh # 可选：重置密钥与面板密码
|
||
bash scripts/install.sh
|
||
```
|
||
|
||
### 改用 Xray 替代 sing-box（可选）
|
||
|
||
若更熟悉 Xray，可使用 `server/xray-server.json.template`：
|
||
|
||
```bash
|
||
# 安装 Xray
|
||
bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install
|
||
|
||
# 渲染配置
|
||
sed -e "s|\${UUID}|...|g" ... server/xray-server.json.template > /usr/local/etc/xray/config.json
|
||
|
||
systemctl restart xray
|
||
```
|
||
|
||
Hysteria2 仍需单独部署（或使用 sing-box 仅跑 Hy2 inbound）。

## 防火墙与安全组对照
|
||
|
||
| 端口 | 协议 | 用途 | 是否必须放行 |
|
||
|------|------|------|-------------|
|
||
| 22 | TCP | SSH | 是 |
|
||
| 80 | TCP | ACME 验证 + **管理面板** | 是 |
|
||
| 443 | TCP | VLESS + Reality | 是 |
|
||
| 8443 | UDP | Hysteria2 | 是 |
|
||
| ~~8444~~ | ~~TCP~~ | ~~旧版面板的独立 HTTPS~~ | **已废弃，无需放行** |
|
||
|
||
## 安全建议
|
||
|
||
- 使用随机 `PANEL_PATH`，不要公开分享面板地址
|
||
- 可选在 `.env` 设置 `PANEL_ALLOW_IP=你的公网IP` 限制访问来源
|
||
- SSH 改用密钥登录，禁用密码：`PermitRootLogin prohibit-password`
|
||
- 可选修改 SSH 端口，ufw 放行新端口后再删 22
|
||
- 不要将 `.env` 或节点分享链接上传到公开仓库
