# 运维与故障排查
|
||
|
||
## 服务检查
|
||
|
||
```bash
|
||
systemctl is-active sing-box jiedian-panel
|
||
sing-box check -c /etc/sing-box/config.json
|
||
ss -ulnp | grep 8443
|
||
```
|
||
|

|
||
|
||
## 常见问题
|
||
|
||
### Hy2 连不上
|
||
|
||
1. 安全组放行 **8443–8499/UDP**
|
||
2. 域名解析到 VPS IP
|
||
3. 从面板 **重新复制** Hy2 链接（多节点端口 8443、8444…）
|
||
4. `systemctl restart sing-box`
|
||
|
||
### 面板打不开
|
||
|
||
- 使用 **`http://域名/PANEL_PATH/`**，不要用 https
|
||
- 443 未用于面板，面板在 **80** 端口
|
||
|
||
### 增删节点后 503
|
||
|
||
等 5–10 秒刷新；sing-box 重启期间可能短暂不可用。
|
||
|
||
### 从旧版 VLESS 迁移
|
||
|
||
```bash
|
||
cd /opt/jiedian && git pull
|
||
sudo bash scripts/remove-vless.sh
|
||
```
