源站装 TLS 证书 + 停掉旧服务器
== 522 的根因 ==
DNS 配好、橙色云朵生效之后:
http://yk.xxmxxs.top/ -> 200(经 Cloudflare,反代正常)
https://yk.xxmxxs.top/ -> 522
13.54.30.196:443 -> 不通
zone 的 SSL/TLS 模式是 **Full / Full(strict)**,Cloudflare 回源走 443,
而源站只听了 80 —— 因此 522。
== 解决:源站签 Let's Encrypt 证书 ==
用 certbot 的 nginx 插件签(**不需要 webroot**,插件自己处理挑战):
Successfully received certificate
/etc/letsencrypt/live/yk.xxmxxs.top/fullchain.pem
notAfter = Jan 6 2027(自动续期已启用 certbot.timer)
nginx 已加 listen 443 + 证书 + http->https 跳转
**开着橙色云朵也能签**:HTTP-01 挑战请求
http://yk.xxmxxs.top/.well-known/acme-challenge/... 会经 Cloudflare
回源到 80,CF 不缓存该路径、会透传,所以验证能过。
比"先关云朵签完再开"省事,也不用等 DNS 传播。
踩的坑:第一次用了 xmz7891@example.com,Let's Encrypt 拒收
example.com 这类保留域名,报"invalid email"。
改用 --register-unsafely-without-email 即可
(续期由 timer 负责,不依赖邮件提醒)。
== 停掉旧服务器 ==
中转已在 Lightsail 跑通,旧那台(随身 WiFi + 两条 CF 隧道 + 网络调优)
全部停掉并取消自启:
lanremote-relay / lanremote-tunnel / lanremote-tunnel-h2 /
lanremote-nettune / monitor.timer / watchdog.timer -> 全 inactive
**只停服务,没关机、没删文件** —— 保持可逆,新服务器稳几天再说。
== 待用户操作 ==

背景:522 是因为 Cloudflare 的 SSL 模式是 Full/Full(strict),
|

|
回源走 443,而源站只有 80。现在证书签好了、nginx 也配了 443,
|

所以要确认:
|

1. 本机 443 能自测通(带正确 SNI)

2. 从**外面**能不能连上 443

—— 这一步取决于用户在 Lightsail 防火墙开没开 443

r'''停掉旧那台随身 WiFi 服务器上的中转。
|
||||||
|
|
||||||
|
== 为什么可以停 ==
|
||||||
|
|
||||||
|
中转已经搬到 AWS Lightsail(有公网 IP、域名 yk.xxmxxs.top、
|
||||||
|
经 Cloudflare CDN),旧机器上那套(lanremote-relay + 两条
|
||||||
|
Cloudflare 隧道 + 网络调优)全部不再需要。
|
||||||
|
|
||||||
|
旧那套的问题回顾(都是停掉它的理由):
|
||||||
|
* 线路对隧道 7844 端口间歇性阻断 -> 隧道每 3~10 分钟掉一次
|
||||||
|
* 只有 460MB 内存
|
||||||
|
* 会掉电硬挂(2026-10-08 18:42 一次非正常关机)
|
||||||
|
|
||||||
|
== 停的方式:**只停服务,不关机、不删东西** ==
|
||||||
|
|
||||||
|
用户说的是"可以停了"。按最小动作来:
|
||||||
|
|
||||||
|
* systemctl stop + disable 那几个服务
|
||||||
|
* **不**关机(万一还想上去看日志)
|
||||||
|
* **不**删任何文件(可逆)
|
||||||
|
|
||||||
|
这样如果新服务器出问题,随时可以 systemctl start 回去。
|
||||||
|
等新服务器稳定跑一阵,再彻底关机/退订也不迟。

r'''给源站签一张 Let's Encrypt 证书,让 Cloudflare 的 SSL 能走"完全(严格)"。
|
||||||
|
|
||||||
|
== 522 是怎么来的 ==
|
||||||
|
|
||||||
|
DNS 配好、橙色云朵生效之后:
|
||||||
|
|
||||||
|
http://yk.xxmxxs.top/ -> 200 (经 Cloudflare,反代是好的)
|
||||||
|
https://yk.xxmxxs.top/ -> 522 (Cloudflare 连不上源站)
|
||||||
|
13.54.30.196:443 -> 不通(源站没听 443)
|
||||||
|
|
||||||
|
结论:zone 的 SSL/TLS 模式是 **Full** 或 **Full (strict)**,
|
||||||
|
Cloudflare 回源走 443,而源站只有 80 -> 522。
|
||||||
|
|
||||||
|
== 两种解法 ==
|
||||||
|
|
||||||
|
A. 把 SSL/TLS 改成 **Flexible**
|
||||||
|
一个下拉框搞定。CF<->用户加密,**CF<->源站明文**。
|
||||||
|
省事,但源站那段不加密 —— 而且 Cloudflare 官方不建议
|
||||||
|
(源站流量在 CF 内网走,风险不大,但"完全"更好)。
|
||||||
|
|
||||||
|
B. 源站装证书,保持 **Full (strict)** <- 这个脚本做的
|
||||||
|
端到端加密,还能开 HSTS 之类。多花两分钟,值得。
|
||||||
|
|
||||||
|
== 为什么开着橙色云朵也能签 Let's Encrypt ==
|
||||||
|
|
||||||
|
HTTP-01 验证是:Let's Encrypt 去请求
|
||||||
|
http://yk.xxmxxs.top/.well-known/acme-challenge/<随机串>
|
||||||
|
这条请求会经过 Cloudflare 回源到我们的 80 端口。
|
||||||
|
Cloudflare 默认**不缓存** .well-known 路径、也会透传,所以能验证成功。
|
||||||
|
(这比"先关云朵签完再开"省事,也不用等 DNS 传播。)
|
||||||
|
|
||||||
|
== 签完还要做的 ==
|
||||||
|
|
||||||
|
1. 用户在 Lightsail 防火墙**开 443**
|
||||||
|
2. 用户把 Cloudflare 的 SSL/TLS 设为 **Full (strict)**
