Server: jpa
IP: 47.245.60.134
OS: Debian 12 (bookworm)
Purpose: Proxy server (X-UI + Xray + IPsec/L2TP)

Services:
  - X-UI (port 6688)
  - Xray (ports: 5555, 5556, 1116)
  - IPsec/L2TP (strongSwan + xl2tpd)
  - SSH (port 22)
  - No web server, no databases, no Docker

Key Paths:
  - /root/ - Scripts (bbr3.sh, l2tp.sh, xray.sh, kejilion.sh, etc.)
  - /etc/x-ui/ - X-UI database
  - /etc/ipsec.d/ - IPsec configs
  - /etc/xl2tpd/ - L2TP configs
  - /etc/strongswan.d/ - strongSwan configs

Backup Files:
  - jpa-backup.tar.gz (297K) - Contains /root/*.sh, /etc/x-ui/, /etc/ipsec.d/, /etc/xl2tpd/, /etc/strongswan.d/

Note: X-UI and IPsec/L2TP configs are for reference only. No custom apps, no websites.

Recovery Steps:
  1. Install dependencies: apt install -y xray x-ui strongswan xl2tpd
  2. Restore configs: tar -xzf jpa-backup.tar.gz -C /
  3. Restart services as needed
  4. Use scripts in /root/ for reinstallation if needed

=== 7/31补充 ===
- jpa-root-nginx-20260731.tar.gz (101M) - /root 全量 (原备份7/8, 有7/30新脚本) + /etc/nginx (vps_proxy.conf)
- 注: 实际有 nginx 服务运行中 (README原述无web server)
- 注: 7/30 安装 opencode (AGENTS.md/setup-opencode-memory.sh, .opencode 234M)
