Edge Node Provision

Edge Node Provision

Turn a bare Debian/Ubuntu VPS into a fully managed edge node with one guided workflow. This skill captures a battle-tested deployment: control-panel + proxy + WARP clean-exit + wildcard TLS + DNS + monitoring, plus every pitfall learned the hard way.

What it builds

This is a template, not a turnkey binary. You supply your own domain, Cloudflare token, server IP, and passwords. No secrets, domains, or routing rules are baked in.

Inputs to collect first

Fill a working copy of scripts/config.env.example → config.env (git-ignored by you). Collect these before touching the box:

• SERVER_IP / SERVER_IPV6 — the new VPS public addresses (amd64 or arm64)
• SSH_USER / SSH_KEY — root or a sudo user (scripts escalate via sudo), and the private key
• TZ — server timezone (default UTC)
• DOMAIN_ROOT — the sub-zone this node owns, e.g. nodeA.example.com (you get *.nodeA.example.com)
• ACME_DNS_PLUGIN + creds — DNS provider for the wildcard cert. Default dns_cf (Cloudflare). Any acme.sh-supported provider works (DNSPod/Aliyun/Route53/GoDaddy/…) — set the plugin + its env vars (references/dns-records.md).
• CF_API_TOKEN / CF_ZONE_ID — Cloudflare only: token with Zone:DNS:Edit (enables the turnkey A/AAAA record script). Non-CF users create the A/AAAA records themselves.
• SUB_PANEL / SUB_XUI / SUB_COVER — the subdomain labels for the three planes. If your zone is public, choose non-obvious labels — don't reuse a guessable convention or people can enumerate your control planes from DNS.
• AAPANEL_USER / AAPANEL_ENTRANCE — desired panel username + secret entrance path (e.g. /somesecret)
• XUI_USER / XUI_PATH — 3x-ui username + webBasePath (e.g. /somesecret/)
• passwords — generate strong ones at runtime; store them in your password manager, never in git
• monitoring (optional) — Nezha SERVER:PORT + shared key; Komari endpoint + auto-discovery key

Workflow

Run steps in order. Each script is idempotent and reads config.env. SSH into the box as root (or a sudo user) for on-box steps.

0. Verify access & prep

scripts/00-preflight.sh          # confirms SSH, records specs, sets timezone, installs base pkgs (curl/gnupg/ufw)

Also drop your public key into the box's ~/.ssh/authorized_keys for passwordless login, and (optional) add an entry to your SSH shortcut/config.

1. Wildcard DNS records

python3 scripts/02-cf-dns.py     # Cloudflare: upserts <root> + *.<root> A/AAAA -> SERVER_IP/IPV6 (proxied=false)

Cloudflare users run the script (token stays off the VPS). Non-Cloudflare users create the same four records by hand — see references/dns-records.md (two names, A + AAAA, DNS-only/unproxied).

2. Wildcard TLS cert (acme.sh DNS-01)

scripts/03-sign-wildcard-cert.sh   # on-box acme.sh --dns dns_cf, issues *.<root> (ECDSA P-256, Let's Encrypt)

Installs the cert into the BT cert dirs and registers a renew --reloadcmd. (For a fleet, see references/centralized-certs.md to sign on one host and scp to the rest.)

3. aaPanel International + nginx

scripts/04-install-aapanel.sh    # official install_7.0_en.sh (headless); waits for panel binary
scripts/05-harden-aapanel.sh     # sets username/password/entrance, binds panel domain, CDN_PROXY=True
scripts/04b-install-nginx.sh     # install_soft.sh 0 install nginx 1.24 (aaPanel-managed)

4. Cloudflare WARP (clean exit)

scripts/06-install-warp.sh       # cloudflare-warp, proxy mode SOCKS5 127.0.0.1:40000, verify warp=on
scripts/06b-warp-watchdog.sh     # installs warp-healthcheck.sh + systemd timer (self-heal every 60s)

5. 3x-ui (Xray) + inbounds

scripts/07-install-3xui.sh       # installs 3x-ui, sets panel 127.0.0.1:14533 + XUI_PATH + creds
scripts/08-xui-bootstrap.sh      # adds direct + WARP inbounds (your WS_PATH_*) + client + xray template

6. aaPanel sites (panel-native, UI-manageable)

scripts/09-aapanel-sites.sh      # AddSite + SetSSL + CreateProxy + HttpToHttps for 4 domains, via panel classes
scripts/09b-default-444.sh       # unmatched server_name -> return 444; drop landing page

7. Firewall + monitoring (optional)

scripts/10-ufw.sh                # allow 22/80/443 + panel port + aaPanel 888/39000-40000
scripts/11-monitoring.sh         # optional: install Nezha + Komari agents (placeholders in config.env)

8. Smoke test

scripts/12-smoke-test.sh         # WS 101 on both cover paths; panels 200; landing 200; e2e exit IPs (direct vs WARP)

Expected: the direct-path egress = SERVER_IP, the WARP-path egress = a Cloudflare WARP IP (warp=on).

Domains this creates

With DOMAIN_ROOT=nodeA.example.com and the example labels SUB_COVER=edge, SUB_XUI=gateway, SUB_PANEL=console (pick your own):

The labels above are just examples. Never publish the real labels you pick — on a public zone they are the map to your control planes.

References

• references/pitfalls.md — read first. The non-obvious failures (aaPanel service model, anti-scan fake 404, new-schema 3x-ui client tables, WARP keyring/gnupg, nginx http2 syntax, etc.). Skipping it costs hours.
• references/dns-records.md — the exact records to create, and how to use a non-Cloudflare DNS provider.
• references/centralized-certs.md — sign wildcards on one host and push to a fleet.

Works with any agent

The workflow is plain bash/python — drive it with Claude Code (SKILL.md), Codex/others (AGENTS.md), or by hand (README.md). Nothing here is model-specific.

Privacy / safety notes

• Never commit config.env, cert keys, panel/xui passwords, or any UUID/token. Add them to your password manager.
• The scripts contain no real domains, IPs, subscription rules, or routing policy — only placeholders. Keep it that way when you adapt them.
• WARP mode here is for your own clean egress; it is not a bypass for anyone else's controls.
