隧道"假活"真因修复 + 中转管理后台重做
用户反馈两件事:
1. 早上打开 relay.xxmxxs.top 看到 Cloudflare Error 1033 —— "这就是你说的优化好了?"
2. "中转管理那边 ui 界面大改,现在难看的要死"
============ 一、隧道 1033/502/530 的真因 ============
之前我只测 15~25 次就说"可用率 100%",太草率 ——
实际是**间歇性假活**:隧道显示 ha_connections=2 连着,
公网却 502/530/000。watchdog 日志把过程记了下来。
根因:**4G 链路静默断开 TCP 连接**(不发 FIN/RST,双方都以为还活着)。
Cloudflare 把请求发到这条僵尸连接上就回错误。
Linux 默认 tcp_keepalive_time = **7200 秒(2 小时)**才发现,
中间这段时间服务一直"看着在线、实际打不开"。
修法(都有实测数据支撑):
1. tcp_keepalive 30 秒 + 每 10 秒探测 3 次
=> 最多约 60 秒发现僵尸连接并重连
2. 隧道连接数 2 -> 4
(对照实验:http2+2 只有 1 条连上时公网 0/12;
http2+4 稳定 12/12。连接数太少会出现"只有 1 条"的危险窗口)
3. 协议定为 http2(cloudflared 自检说 TCP 7844 被墙,
但实测 http2 反而比 quic 稳)
实测:http2+4 之后公网 40/40 = 100%,最慢 1.3 秒,0 次重连。
============ 二、中转管理后台重做 ============
原来是几百行内联在 relay.py 的 f-string 里(HTML+CSS+JS 全挤一起),
改一处样式要在一堆转义花括号里翻。拆成独立模块 relay/admin.py。
新版设计(对齐官网那套白色简洁):
* 吸顶顶栏:品牌 + 运行状态 + 版本/内存/请求数
* 公网地址给最大权重(这是用户最需要复制的东西)
* 四个数字卡(在线/会话数带颜色区分)
* 设备表卡片:状态圆点、等宽配对码、行悬停
* 工具卡:网络体检 + 下载区并排
* 空状态改成图标+引导文案,不再是干巴巴一句
* 窄屏时表格自动变卡片
relay.py 从 2089 行缩到 1550 行。
============ 三、顺手修的两个真 bug ============
1. 设备记录只增不减
self.devices 从不清理,被控端每次换端口/重装就多一条,
实测一天攒了 75 条僵尸记录,/v1/health 从几 KB 涨到 20KB。
加 DEVICE_TTL(6 小时)在 snapshot() 里清。
2. 配对码映射也没清
RELAY.codes 和 devices 是一对孪生 dict,
只清 devices 会留下指向已删设备的孤儿条目 ——
管理页显示"配对码占用 131",实际一台设备都没有。
现在一起清。
============ 四、我自己造的两次事故(如实记录) ============
1. 删文件删过头
用"从 _admin_page 截到文件末尾"的方式替换方法,
但 _admin_page 后面**还有 _esc/_kb/_uptime/class Server/main()**。
结果 relay 起不来,systemd 重启 24 次,所有接口 000。
教训:**"删到文件末尾"之前必须先确认末尾有什么。**
2. ADMIN_PATH 引用了不存在的常量
路由里写的是字面量,我却在新代码里用了 ADMIN_PATH,
管理页一访问就 NameError。现在统一定义了常量。
二者都是"改完没立刻验"造成的。现在每次改完都跑一遍
管理页 + 官网 + 关键接口的回归。

r'''中转站管理后台的页面渲染(独立模块)。
|
||||
|
||||
为什么拆出来:
|
||||
原来这一大坨内联在 relay.py 里(几百行 f-string + CSS + JS),
|
||||
改一处样式要在一堆转义的花括号里找,改不动也没法看。
|
||||
拆成模块后:CSS 是普通字符串、HTML 用普通格式化,清爽多了。
|
||||
|
||||
设计目标(用户反馈"难看的要死"):
|
||||
* 和官网共用一套设计语言:白底、浅灰面板、细边框、克制的蓝
|
||||
* 信息分层次:
|
||||
顶部栏(我是谁、什么状态)
|
||||
-> 公网地址(最该被看到、要复制的东西,给最大权重)
|
||||
-> 四个数字(一眼看全局)
|
||||
-> 设备表(主内容)
|
||||
-> 工具卡(体检、下载,次要,放最后)
|
||||
* 表格:状态用圆点+文字,配对码等宽字体,行悬停高亮
|
||||
* 空状态要友好,不是干巴巴一句"没有数据"
|
||||
|
||||
功能一个都不能少(对应用户能做的事):
|
||||
单台删除 / 勾选批量删除 / 删除全部 / 复制公网地址 /
|
||||
网络体检 / 下载最新版 / 自动刷新开关
