+
+## 数据关联结论
+
+展厅的 3 个一级单元当前均为 `stopCount=0`，而详情讲解点 `865546647764037632` 实际属于单元 `865546627916591104`，该单元可返回 39 条讲解点。这说明一级单元目录与讲解点关联仍存在后端数据不一致。H5 主流程保持为 `展厅 -> 讲解对象 -> 统一详情`，不以一级单元作为主导航。
+
+统一详情即使参数错误也使用 HTTP `200`，客户端必须结合业务 `code` 判断结果。语言和性别均由当前版本的详情数组在本地切换；切换标准版与拓展版时才重新请求统一详情并传入 `version`。

+# 测试服务器导览 H5 部署手册
+
+最后更新：2026-09-15
+
+## 1. 部署目标
+
+- 站点：`guide.whaoyue.com`
+- 服务器公网 IP：`124.220.83.186`
+- SSH 用户：`root`
+- 操作系统：Ubuntu 22.04.5 LTS
+- HTTPS 入口：`https://guide.whaoyue.com:4433/`
+- HTTP/IP 测试入口：`http://124.220.83.186:8888/`
+- 部署对象：`frontend-miniapp` H5 构建产物
+- Nginx 容器：`sgs-nature-nginx`
+
+`8888` 直接提供明文 HTTP，不再跳转到 HTTPS，并接受域名、公网 IP 和其他 Host。HTTP 仅用于测试；请求内容、登录凭据和 Token 均不会被加密，不得作为生产入口。
+
+Nginx 源站也支持 `http://guide.whaoyue.com:8888/`，但截至 2026-09-15，腾讯侧会在请求到达 Nginx 前将该域名 HTTP 请求重定向到 DNSPod `webblock` 页面。因此公网 HTTP 验收应使用 IP 入口；该外部拦截不能通过本机 Nginx 配置消除。
+
+域名 DNS A 记录应指向：
+
+```text
+guide.whaoyue.com -> 124.220.83.186
+```
+
+## 2. 当前部署拓扑
+
+```text
+公网用户
+  -> 124.220.83.186:8888（HTTP）/ guide.whaoyue.com:4433（HTTPS）
+  -> sgs-nature-nginx Docker 容器
+  -> 容器使用 host 网络
+  -> /usr/share/nginx/html/guide
+  -> 宿主机 /data/sgs-nature/web/guide
+```
+
+`sgs-nature-nginx` 当前不是 Docker Compose、Docker Stack、systemd 或 1Panel 项目管理的容器，而是手动创建并启动的 Docker 容器。
+
+容器实际参数：
+
+```text
+镜像：nginx:latest
+Nginx：1.31.3
+网络：host
+重启策略：unless-stopped
+启动命令：nginx -g 'daemon off;'
+```
+
+当前容器挂载：
+
+| 宿主机路径 | 容器路径 | 权限 | 用途 |
+| --- | --- | --- | --- |
+| `/data/sgs-nature/deploy/nginx.conf` | `/etc/nginx/conf.d/default.conf` | 只读 | Nginx 配置 |
+| `/data/sgs-nature/web` | `/usr/share/nginx/html` | 只读 | 静态站点和资源 |
+
+由于容器使用 `host` 网络，Docker 没有 `-p` 端口映射。Nginx 配置中的 `listen 8888` 和 `listen 4433` 就是宿主机的监听端口。`8888` 直接提供 HTTP，`4433` 提供 HTTPS。
+
+不要操作或重启服务器上另一个名为 `nginx` 的容器。该容器占用公网标准端口 `80/443`，与本导览容器职责不同。因此导览 HTTP 入口必须显式携带 `:8888`，不能使用无端口的 `http://124.220.83.186/`。
+
+## 3. 服务器目录
+
+导览站点目录：
+
+```text
+/data/sgs-nature/web/guide/
+```
+
+容器内对应目录：
+
+```text
+/usr/share/nginx/html/guide/
+```
+
+证书目录按当前部署方案放在已有 Web 挂载目录内：
+
+```text
+/data/sgs-nature/web/ssl/guide.whaoyue.com/fullchain.pem
+/data/sgs-nature/web/ssl/guide.whaoyue.com/privkey.pem
+```
+
+容器内证书路径：
+
+```text
+/usr/share/nginx/html/ssl/guide.whaoyue.com/fullchain.pem
+/usr/share/nginx/html/ssl/guide.whaoyue.com/privkey.pem
+```
+
+证书目录位于 Web 挂载目录下，因此 Nginx 配置必须拒绝公网访问：
+
+```nginx
+location ^~ /ssl/ {
+    deny all;
+    return 404;
+}
+```
+
+证书权限建议：
+
+```text
+fullchain.pem：0644
+privkey.pem：0600
+```
+
+相关部署和备份文件：
+
+```text
+/data/sgs-nature/deploy/nginx.conf
+/data/sgs-nature/backup/
+```
+
+## 4. 本地构建
+
+项目根目录：
+
+```text
+E:\MyWork\深圳国际艺术馆\museum-guide\museum-guide-v4.0\frontend-miniapp
+```
+
+环境要求：
+
+- Node.js `>=20 <25`
+- pnpm 9
+
+安装依赖：
+
+```powershell
+pnpm install
+```
+
+测试环境默认配置文件为 `.env.test`，关键配置如下：
+
+```dotenv
+VITE_APP_PUBLIC_BASE=/
+VITE_GUIDE_DATA_SOURCE_MODE=sdk
+VITE_EXPLAIN_CONTENT_SOURCE_MODE=remote
+VITE_DATA_SOURCE_MODE=sdk
+VITE_GUIDE_CONTENT_SOURCE_MODE=remote
+VITE_GUIDE_STATIC_DATA_BASE_URL=/static/guide-data
+VITE_API_BASE_URL=/app-api
+VITE_AUDIO_API_BASE_URL=/app-api
+VITE_SGS_API_BASE_URL=/app-api
+VITE_SGS_MAP_ID=1
+VITE_SGS_SDK_SCRIPT_URL=/static/sgs-map-sdk/index.global.js?v=2.5.0
+VITE_SGS_H5_ENGINE_URL=/engine/index.html
+VITE_SGS_SDK_ORIGIN=
+```
+
+由于站点通过域名根路径提供服务，`VITE_APP_PUBLIC_BASE` 必须为 `/`，不能设置为 `/guide/`。`guide` 是服务器上的目录名，不是 URL 路径。
+
+执行质量检查和测试构建：
+
+```powershell
+pnpm type-check
+pnpm lint
+pnpm build:test:h5
+```
+
+`pnpm build:test:h5` 会生成 H5 产物，并复制以下资源：
+
+- `static/nav-assets`
+- `static/guide-data`
+- `static/sgs-map-sdk`
+- `static/three`
+- `static/icons`
+- `static/explain`
+- `static/Fonts`
+- `engine`
+- 讲解图片、占位图片等补充资源
+
+构建目录：
+
+```text
+dist/build/h5/
+```
+
+生产发布需要真实腾讯地图 Web Key 时，使用生产构建：
+
+```powershell
+$env:VITE_TENCENT_MAP_KEY = '<真实腾讯地图 Web Key>'
+pnpm build:h5
+Remove-Item Env:VITE_TENCENT_MAP_KEY
+```
+
+不要将真实 Key、密码、Token 或其他密钥提交到仓库。
+
+构建后建议检查：
+
+```powershell
+Test-Path dist\build\h5\index.html
+Get-ChildItem dist\build\h5 -Recurse -File | Measure-Object Length -Sum
+rg -n -S --glob '!*.map' '1\.92\.206\.90|guide\.whaoyue\.com|http://124\.220\.83\.186:9000' dist\build\h5
+```
+
+最后一个命令不应出现旧服务器地址或不应使用的绝对 HTTP 资源地址。
+
+## 5. 打包和上传
+
+在项目根目录执行：
+
+```powershell
+New-Item -ItemType Directory -Force -Path '.tmp' | Out-Null
+$archive = '.tmp\museum-guide-h5.tar.gz'
+if (Test-Path -LiteralPath $archive) {
+    Remove-Item -LiteralPath $archive -Force
+}
+tar -C 'dist\build\h5' -czf $archive .
+```
+
+SSH 主机别名为：
+
+```text
+museum-guide-test
+```
+
+该别名位于本机：
+
+```text
+C:\Users\Administrator\.ssh\config
+```
+
+上传构建包：
+
+```powershell
+scp '.tmp\museum-guide-h5.tar.gz' 'museum-guide-test:/tmp/museum-guide-h5.tar.gz'
+```
+
+不要把密码写入 SSH 配置、命令脚本或部署文档。
+
+## 6. 证书
+
+当前使用的证书为 `guide.whaoyue.com` 的 Let’s Encrypt 证书，记录的有效期为：
+
+```text
+Not Before: 2026-06-07 15:33:10 GMT
+Not After:  2026-09-05 15:33:09 GMT
+```
+
+截至 2026-09-15，该证书已经过期。`4433` 仍能建立忽略证书校验的 HTTPS 连接，但浏览器会显示安全警告；应尽快完成证书续期。开放 `8888` HTTP 仅用于测试，不替代证书续期。
+
+查看证书：
+
+```bash
+openssl x509 \
+  -in /data/sgs-nature/web/ssl/guide.whaoyue.com/fullchain.pem \
+  -noout -subject -issuer -dates
+```
+
+证书续期注意事项：
+
+- 新服务器目前没有发现已配置的 `acme.sh` 或 `certbot` 续期任务。
+- Let’s Encrypt HTTP-01 验证固定使用公网 `80`，不会访问 `8888`。
+- 公网 `80/443` 已被服务器上另一个 `nginx` 容器占用。
+- 证书到期前必须配置 DNS-01，或者制定临时借用公网 `80` 完成验证的方案。
+- 续期后需要把新证书复制到上述目录，并执行 Nginx 配置检查和 reload。
+
+续期后的最低操作：
+
+```bash
+docker exec sgs-nature-nginx nginx -t
+docker exec sgs-nature-nginx nginx -s reload
+openssl x509 \
+  -in /data/sgs-nature/web/ssl/guide.whaoyue.com/fullchain.pem \
+  -noout -subject -issuer -dates
+```
+
+## 7. Nginx 配置
+
+配置文件：
+
+```text
+/data/sgs-nature/deploy/nginx.conf
+```
+
+当前已有 `18101` server，服务 `/dp/`、`/gl/`、`/map/` 及自然馆测试环境 API。新增导览站点时不得删除或覆盖该 server。
+
+导览 HTTP 与 HTTPS 由同一个 server 块提供，以避免两套静态资源和反向代理规则发生漂移。核心配置：
+
+```nginx
+server {
+    # 测试环境明文 HTTP；公网 80 仍由另一 nginx 容器占用。
+    listen 8888 default_server;
+    listen 4433 ssl;
+    server_name guide.whaoyue.com 124.220.83.186 _;
+
+    root /usr/share/nginx/html/guide;
+    index index.html;
+
+    ssl_certificate /usr/share/nginx/html/ssl/guide.whaoyue.com/fullchain.pem;
+    ssl_certificate_key /usr/share/nginx/html/ssl/guide.whaoyue.com/privkey.pem;
+
+    location ^~ /ssl/ {
+        deny all;
+        return 404;
+    }
+
+    location ^~ /static/nav-assets/ {
+        try_files $uri =404;
+    }
+
+    location ^~ /assets/ {
+        try_files $uri =404;
+    }
+
+    location ^~ /engine/ {
+        try_files $uri =404;
+    }
+
+    location ^~ /static/ {
+        try_files $uri =404;
+    }
+
+    location ^~ /app-api/ {
+        proxy_pass http://127.0.0.1:48100;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection $connection_upgrade;
+        proxy_read_timeout 300s;
+        proxy_send_timeout 300s;
+    }
+
+    location ^~ /minio/ {
+        proxy_pass http://127.0.0.1:9000/;
+        proxy_http_version 1.1;
+        proxy_set_header Host 127.0.0.1:9000;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_read_timeout 300s;
+    }
+
+    location ^~ /museum-assets/ {
+        proxy_pass http://127.0.0.1:9000/museum-assets/;
+        proxy_http_version 1.1;
+        proxy_set_header Host 127.0.0.1:9000;
+        expires 30d;
+        add_header Cache-Control "public";
+        proxy_read_timeout 300s;
+    }
+
+    location / {
+        try_files $uri $uri/ /index.html;
+    }
+}
+```
+
+`/static/nav-assets/` 必须使用 `try_files $uri =404`，避免缺失 JSON、GLB 或其他模型资源时错误返回 SPA 的 `index.html`。
+
+修改配置前备份：
+
+```bash
+TS=$(date +%Y%m%d%H%M%S)
+cp -p /data/sgs-nature/deploy/nginx.conf \
+  "/data/sgs-nature/backup/nginx-before-guide-$TS.conf"
+```
+
+配置文件以单文件 bind mount 方式挂载。修改时必须保留宿主机文件 inode，例如原地编辑或使用 `cat candidate.conf > "$CONFIG"`；不要使用 `mv`、`install` 或其他原子替换方式覆盖路径。替换 inode 后，容器会继续看到旧文件，普通 reload 不会载入新配置。
+
+修改后先确认宿主机和容器内文件一致，再检查并 reload：
+
+```bash
+CONFIG=/data/sgs-nature/deploy/nginx.conf
+sha256sum "$CONFIG"
+docker exec sgs-nature-nginx \
+  sha256sum /etc/nginx/conf.d/default.conf
+
+docker exec sgs-nature-nginx nginx -t
+docker exec sgs-nature-nginx nginx -s reload
+```
+
+配置检查失败时不得 reload。应使用备份原地恢复配置，重新执行 `nginx -t`，确认通过后再 reload。如果已经替换了 inode，应先用独立临时容器对宿主机新配置执行 `nginx -t`，然后只重启 `sgs-nature-nginx` 使其重新建立挂载；仍然不要操作另一个名为 `nginx` 的容器。
+
+本部署方式不需要：
+
+- 新增 Docker Compose 文件
+- 新增 Nginx systemd 服务
+- 新增 Docker 端口映射
+- 重启服务器原有 `nginx` 容器
+
+## 8. 发布站点文件
+
+上传压缩包后，在服务器上执行。发布前先备份当前 `guide` 目录：
+
+```bash
+set -e
+SITE=/data/sgs-nature/web/guide
+ARCHIVE=/tmp/museum-guide-h5.tar.gz
+TS=$(date +%Y%m%d%H%M%S)
+BACKUP=/data/sgs-nature/backup
+
+mkdir -p "$SITE" "$BACKUP"
+if [ -f "$SITE/index.html" ]; then
+    tar -C "$SITE" -czf "$BACKUP/guide-before-deploy-$TS.tar.gz" .
+fi
+
+test -f "$ARCHIVE"
+find "$SITE" -mindepth 1 -maxdepth 1 -exec rm -rf -- {} +
+tar -C "$SITE" -xzf "$ARCHIVE"
+mkdir -p /data/sgs-nature/web/ssl/guide.whaoyue.com
+
+printf 'backup=%s\n' "$BACKUP/guide-before-deploy-$TS.tar.gz"
+printf 'files=%s\n' "$(find "$SITE" -type f | wc -l)"
+```
+
+证书目录不属于 H5 构建包，不能在清理站点目录时误删。证书位于同级的 `/data/sgs-nature/web/ssl/`，不在 `/data/sgs-nature/web/guide/` 内。
+
+如果证书需要更新：
+
+```bash
+install -o root -g root -m 0644 fullchain.pem \
+  /data/sgs-nature/web/ssl/guide.whaoyue.com/fullchain.pem
+install -o root -g root -m 0600 privkey.pem \
+  /data/sgs-nature/web/ssl/guide.whaoyue.com/privkey.pem
+```
+
+## 9. 部署后验证
+
+### 9.1 DNS 和端口
+
+在 Windows PowerShell 中：
+
+```powershell
+Resolve-DnsName guide.whaoyue.com -Type A
+Test-NetConnection 124.220.83.186 -Port 8888
+Test-NetConnection guide.whaoyue.com -Port 4433
+```
+
+DNS A 记录应为 `124.220.83.186`。
+
+### 9.2 HTTP/IP 和 HTTPS
+
+```powershell
+curl.exe -I --max-time 30 http://124.220.83.186:8888/
+curl.exe -k -I --max-time 30 https://guide.whaoyue.com:4433/
+```
+
+期望：
+
+```text
+124.220.83.186:8888：200 OK，不跳转
+guide.whaoyue.com:4433：200 OK
+```
+
+公网直接访问 `http://guide.whaoyue.com:8888/` 可能收到腾讯 DNSPod `webblock` 的 `302`，这不代表源站 Nginx 未启用 HTTP。可在服务器本机携带域名 Host 验证源站：
+
+```bash
+curl -I -H 'Host: guide.whaoyue.com' http://127.0.0.1:8888/
+```
+
+源站期望返回 `200 OK`。
+
+检查证书：
+
+```powershell
+cmd /c "echo.| openssl s_client -connect guide.whaoyue.com:4433 -servername guide.whaoyue.com 2>NUL | openssl x509 -noout -subject -issuer -dates"
+```
+
+### 9.3 关键静态资源
+
+不要固定使用旧版本的导航资源目录名。先从构建产物或服务器目录查找当前 Manifest：
+
+```bash
+find /data/sgs-nature/web/guide/static/nav-assets \
+  -name app_nav_manifest.json -print
+```
+
+假设当前资源包目录为：
+
+```text
+/static/nav-assets/<当前资源包目录>/
+```
+
+验证 Manifest、楼层数据和 GLB：
+

+curl.exe -I --max-time 30 http://124.220.83.186:18101/dp/
+```
+
+期望：
+
+```text
+HTTP 与 HTTPS /app-api/gis/sdk/maps/1/manifest：200 application/json
+18101 /dp/：200
+```
+
+### 9.5 私钥保护

+- 不存在的模型资源不会返回 HTML
+- `/dp/`、`/gl/`、`/map/` 原有服务未受影响
+
+## 10. 回滚
+
+### 10.1 回滚前端文件
+
+部署时会在以下目录生成备份：
+
+```text
+/data/sgs-nature/backup/guide-before-deploy-YYYYMMDDHHMMSS.tar.gz
+```
+
+回滚：
+
+```bash
+set -e
+SITE=/data/sgs-nature/web/guide
+BACKUP=/data/sgs-nature/backup/guide-before-deploy-YYYYMMDDHHMMSS.tar.gz
+
+test -f "$BACKUP"
+find "$SITE" -mindepth 1 -maxdepth 1 -exec rm -rf -- {} +
+tar -C "$SITE" -xzf "$BACKUP"
+docker exec sgs-nature-nginx nginx -t
+docker exec sgs-nature-nginx nginx -s reload
+```
+
+### 10.2 回滚 Nginx 配置
+
+```bash
+set -e
+CONFIG=/data/sgs-nature/deploy/nginx.conf
+BACKUP=/data/sgs-nature/backup/nginx-before-guide-YYYYMMDDHHMMSS.conf
+
+test -f "$BACKUP"
+cat "$BACKUP" > "$CONFIG"
+chown root:root "$CONFIG"
+chmod 0644 "$CONFIG"
+docker exec sgs-nature-nginx nginx -t
+docker exec sgs-nature-nginx nginx -s reload
+```
+
+回滚时只恢复对应的 `guide` 文件或 Nginx 配置，不要删除整个 `/data/sgs-nature/web`，以免影响 `/dp`、`/gl` 等现有站点。
+
+## 11. 当前部署记录
+
+2026-09-15：
+
+- 将 `8888` 从 HTTP→HTTPS 跳转改为直接提供导览 H5，公网 IP 入口为 `http://124.220.83.186:8888/`
+- `8888` HTTP 与 `4433` HTTPS 共用同一 server 块，支持域名、公网 IP 和其他 Host
+- 配置备份：`/data/sgs-nature/backup/nginx-before-ip-http-20260915114641.conf`
+- 候选配置和运行容器的 `nginx -t` 均通过；因单文件 bind mount 的 inode 被替换，仅重启了 `sgs-nature-nginx` 以重新挂载配置
+- 公网验证：IP HTTP 首页、Manifest、`/app-api/` 均返回 `200`；HTTP/HTTPS 私钥路径均返回 `404`；`4433` HTTPS 与原有 `18101 /dp/` 均返回 `200`
+- 域名 HTTP 请求仍被腾讯 DNSPod `webblock` 在源站前重定向；服务器本机以域名 Host 访问 `8888` 返回 `200`
+- `guide.whaoyue.com` 当前证书已于 2026-09-05 过期，待单独续期
+
+2026-08-27：
+
+- 使用 `pnpm build:test:h5` 构建测试 H5
+- 类型检查通过
+- Lint 无错误，有 1 个既有未使用变量 warning
+- 构建产物 229 个文件，约 204 MB
+- 发布到 `/data/sgs-nature/web/guide`
+- 复用 `/data/sgs-nature/web` 现有挂载存放证书
+- 更新 `/data/sgs-nature/deploy/nginx.conf`
+- `sgs-nature-nginx` 执行 `nginx -t` 和 reload
+- `8888` 跳转、`4433` HTTPS、API、讲解数据、SDK、Engine、GLB 和私钥保护验证通过
+- 原有 `18101 /dp/` 验证通过
+
+本次构建使用测试环境腾讯地图 Key 占位符，不代表正式生产地图 Key 已配置。正式发布前需要注入真实 Key 后重新构建并验证。

+# zjsjgjyyzx.cn 主站 HTTPS 与校验文件部署操作手册
+
+最后更新：2026-09-07
+
+## 1. 适用范围
+
+本文档适用于腾讯云测试服务器上的主站域名 `zjsjgjyyzx.cn`，涵盖：
+
+- Let’s Encrypt SSL 证书申请与部署
+- 保留 HTTP `80` 和 HTTPS `443` 的独立访问能力
+- Certbot 自动续期、证书同步和 Nginx reload
+- 域名根目录 TXT 校验文件发布
+- 配置验证与回滚
+
+本文档**不适用于**导览 H5 站点 `guide.whaoyue.com:8888/4433`。该导览站点使用独立容器 `sgs-nature-nginx`，其部署手册见：
+
+```text
+docs/deployment/guide-test-server-nginx-ssl.md
+```
+
+## 2. 当前部署目标与拓扑
+
+| 项目 | 当前值 |
+| --- | --- |
+| 域名 | `zjsjgjyyzx.cn` |
+| 服务器公网 IP | `124.220.83.186` |
+| HTTP 地址 | `http://zjsjgjyyzx.cn/` |
+| HTTPS 地址 | `https://zjsjgjyyzx.cn/` |
+| 主 Nginx 容器 | `nginx` |
+| Nginx 镜像 | `nginx:latest` |
+| Docker 网络 | `bridge` |
+| 宿主机端口映射 | `80 -> 80`、`443 -> 443` |
+
+请求链路：
+
+```text
+HTTP 用户  -> zjsjgjyyzx.cn:80  -> nginx Docker 容器 -> 后台主站
+HTTPS 用户 -> zjsjgjyyzx.cn:443 -> nginx Docker 容器 -> 后台主站
+```
+
+当前要求是 **HTTP 和 HTTPS 均可直接访问**。不要在 HTTP server 中配置强制跳转到 HTTPS，除非业务要求变更且完成专项验证。
+
+## 3. 关键目录与文件
+
+### 3.1 Nginx
+
+| 宿主机路径 | 容器路径 | 用途 |
+| --- | --- | --- |
+| `/data/nginx/conf/nginx.conf` | `/etc/nginx/nginx.conf` | Nginx 主配置 |
+| `/data/nginx/conf/conf.d/` | `/etc/nginx/conf.d/` | 站点配置目录 |
+| `/data/nginx/html/` | `/usr/share/nginx/html/` | 静态资源根目录 |
+| `/data/nginx/html/admin-ui/` | `/usr/share/nginx/html/admin-ui/` | 主站前端根目录 |
+| `/data/nginx/ssl/` | `/etc/nginx/ssl/` | Nginx 可读取的证书目录 |
+| `/data/nginx/logs/` | `/var/log/nginx/` | Nginx 日志 |
+
+主站 HTTP 配置：
+
+```text
+/data/nginx/conf/conf.d/zhjzpt.conf
+```
+
+主站 HTTPS 配置：
+
+```text
+/data/nginx/conf/conf.d/zhjzpt-ssl.conf
+```
+
+### 3.2 证书
+
+Certbot 管理的原始证书：
+
+```text
+/etc/letsencrypt/live/zjsjgjyyzx.cn/fullchain.pem
+/etc/letsencrypt/live/zjsjgjyyzx.cn/privkey.pem
+```
+
+Nginx 容器读取的同步副本：
+
+```text
+/data/nginx/ssl/zjsjgjyyzx.cn/fullchain.pem
+/data/nginx/ssl/zjsjgjyyzx.cn/privkey.pem
+```
+
+权限要求：
+
+```text
+fullchain.pem: 0644
+privkey.pem:   0600
+```
+
+### 3.3 自动续期 Hook
+
+```text
+/etc/letsencrypt/renewal-hooks/deploy/zjsjgjyyzx.cn-nginx.sh
+```
+
+该 Hook 在证书续期成功后执行以下操作：
+
+1. 将证书复制到 `/data/nginx/ssl/zjsjgjyyzx.cn/`。
+2. 设置证书与私钥的安全权限。
+3. 执行 `docker exec nginx nginx -t`。
+4. 执行 `docker exec nginx nginx -s reload`。
+
+## 4. 部署前检查
+
+### 4.1 DNS 与备案
+
+域名 A 记录必须统一指向：
+
+```text
+zjsjgjyyzx.cn -> 124.220.83.186
+```
+
+至少使用多个公共 DNS 核对：
+
+```bash
+for r in 8.8.8.8 1.1.1.1 223.5.5.5 119.29.29.29; do
+  printf "$r A="
+  nslookup -type=A zjsjgjyyzx.cn "$r" 2>/dev/null |
+    awk '/Address: /{print $2}' | tail -1
+done
+```
+
+如使用阿里云 DNS，可检查权威记录：
+
+```bash
+dig +short A zjsjgjyyzx.cn @dns9.hichina.com
+dig +short A zjsjgjyyzx.cn @dns10.hichina.com
+```
+
+所有结果都应为：
+
+```text
+124.220.83.186
+```
+
+中国大陆服务器使用 HTTP-01 申请证书前，应确保域名备案已通过并已生效。若备案未完成或 DNS 线路未完全刷新，Let’s Encrypt 可能访问到运营商/平台拦截页，导致验证失败。
+
+### 4.2 Nginx 与端口
+
+```bash
+docker inspect nginx --format 'status={{.State.Status}} ports={{json .HostConfig.PortBindings}}'
+docker exec nginx nginx -t
+ss -lntp | grep -E ':(80|443)([[:space:]]|$)'
+```
+
+预期：
+
+- Nginx 容器为 `running`
+- 宿主机 `80` 和 `443` 都由 Docker 映射监听
+- `nginx -t` 通过
+
+### 4.3 ACME 校验路径
+
+HTTP-01 校验规则必须存在于 `zhjzpt.conf` 的 `server` 块内：
+
+```nginx
+location ^~ /.well-known/acme-challenge/ {
+    root /usr/share/nginx/html;
+    try_files $uri =404;
+    default_type text/plain;
+}
+```
+
+验证校验路径：
+
+```bash
+mkdir -p /data/nginx/html/.well-known/acme-challenge
+printf 'acme-check-ok\n' \
+  > /data/nginx/html/.well-known/acme-challenge/verify-test
+
+curl -i http://zjsjgjyyzx.cn/.well-known/acme-challenge/verify-test
+rm -f /data/nginx/html/.well-known/acme-challenge/verify-test
+```
+
+必须收到 `200 OK` 和测试文本；校验文件不能被 SPA fallback 返回为首页 HTML。
+
+## 5. 申请 SSL 证书
+
+### 5.1 安装 Certbot
+
+Ubuntu 22.04：
+
+```bash
+apt-get update -qq
+apt-get install -y -qq certbot
+```
+
+检查：
+
+```bash
+certbot --version
+systemctl status certbot.timer --no-pager
+```
+
+### 5.2 使用 HTTP-01 Webroot 签发
+
+```bash
+certbot certonly \
+  --webroot \
+  -w /data/nginx/html \
+  -d zjsjgjyyzx.cn \
+  --non-interactive \
+  --agree-tos \
+  -m '<运维联系邮箱>' \
+  --keep-until-expiring
+```
+
+成功后检查：
+
+```bash
+openssl x509 \
+  -in /etc/letsencrypt/live/zjsjgjyyzx.cn/fullchain.pem \
+  -noout -subject -issuer -dates
+```
+
+将证书同步到 Nginx 挂载目录：
+
+```bash
+install -d -o root -g root -m 0755 /data/nginx/ssl/zjsjgjyyzx.cn
+install -o root -g root -m 0644 \
+  /etc/letsencrypt/live/zjsjgjyyzx.cn/fullchain.pem \
+  /data/nginx/ssl/zjsjgjyyzx.cn/fullchain.pem
+install -o root -g root -m 0600 \
+  /etc/letsencrypt/live/zjsjgjyyzx.cn/privkey.pem \
+  /data/nginx/ssl/zjsjgjyyzx.cn/privkey.pem
+```
+
+### 5.3 常见申请失败：CA 命中旧 IP 或拦截页
+
+若 Certbot 输出中出现非本服务器 IP，或类似：
+
+```text
+Invalid response from https://dnspod.qcloud.com/static/webblock.html
+```
+
+不要继续重复申请。先检查：
+
+- 所有 DNS 线路是否统一为 `124.220.83.186`
+- 域名备案是否已生效
+- `80` 端口是否可从公网访问
+- `/.well-known/acme-challenge/` 是否返回实际验证文件
+- 是否存在旧 A 记录、CNAME、线路分流或平台拦截
+
+## 6. Nginx 配置
+
+### 6.1 HTTP 80 配置
+
+文件：
+
+```text
+/data/nginx/conf/conf.d/zhjzpt.conf
+```
+
+HTTP 站点应继续：
+
+```nginx
+server {
+    listen 80;
+    server_name zjsjgjyyzx.cn 124.220.83.186 _;
+    # 保留现有静态页面与代理规则
+}
+```
+
+不要加入以下跳转规则，否则不再满足 HTTP、HTTPS 都直接可访问的要求：
+
+```nginx
+return 301 https://$host$request_uri;
+```
+
+### 6.2 HTTPS 443 配置
+
+文件：
+
+```text
+/data/nginx/conf/conf.d/zhjzpt-ssl.conf
+```
+
+HTTPS 配置应与 HTTP 站点保持功能等价，至少包含：
+
+- 静态站点根目录：`/usr/share/nginx/html/admin-ui`
+- `/kkfileview/` 代理
+- `/dp/` 静态目录
+- `/.well-known/acme-challenge/` 规则
+- `/admin-api/` 代理
+- `/app-api/` 代理
+- 根路径 SPA fallback
+
+核心 TLS 配置：
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name zjsjgjyyzx.cn;
+
+    root /usr/share/nginx/html/admin-ui;
+    index index.html;
+    charset utf-8;
+
+    ssl_certificate /etc/nginx/ssl/zjsjgjyyzx.cn/fullchain.pem;
+    ssl_certificate_key /etc/nginx/ssl/zjsjgjyyzx.cn/privkey.pem;
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_session_cache shared:SSL:10m;
+    ssl_session_timeout 10m;
+
+    # 以下保持与 HTTP 站点相同的静态和代理 location
+}
+```
+
+配置修改前先备份：
+
+```bash
+TS=$(date +%Y%m%d%H%M%S)
+cp -p /data/nginx/conf/conf.d/zhjzpt.conf \
+  "/data/nginx/conf/conf.d/zhjzpt.conf.bak-$TS-before-change"
+
+[ ! -f /data/nginx/conf/conf.d/zhjzpt-ssl.conf ] || \
+  cp -p /data/nginx/conf/conf.d/zhjzpt-ssl.conf \
+  "/data/nginx/conf/conf.d/zhjzpt-ssl.conf.bak-$TS"
+```
+
+检查并 reload：
+
+```bash
+docker exec nginx nginx -t
+docker exec nginx nginx -s reload
+```
+
+`nginx -t` 失败时不得 reload。应先恢复备份，重新检查通过后再 reload。
+
+## 7. Certbot 自动续期
+
+### 7.1 Deploy Hook 内容
+
+创建：
+
+```text
+/etc/letsencrypt/renewal-hooks/deploy/zjsjgjyyzx.cn-nginx.sh
+```
+
+内容：
+
+```sh
+#!/bin/sh
+set -eu
+
+DOMAIN="zjsjgjyyzx.cn"
+LIVE="/etc/letsencrypt/live/${DOMAIN}"
+TARGET="/data/nginx/ssl/${DOMAIN}"
+
+install -d -o root -g root -m 0755 "$TARGET"
+install -o root -g root -m 0644 "$LIVE/fullchain.pem" "$TARGET/fullchain.pem"
+install -o root -g root -m 0600 "$LIVE/privkey.pem" "$TARGET/privkey.pem"
+
+docker exec nginx nginx -t
+docker exec nginx nginx -s reload
+```
+
+设置权限：
+
+```bash
+chmod 700 /etc/letsencrypt/renewal-hooks/deploy/zjsjgjyyzx.cn-nginx.sh
+```
+
+### 7.2 测试续期
+
+```bash
+certbot renew --dry-run
+systemctl is-enabled certbot.timer
+systemctl is-active certbot.timer
+```
+
+预期：
+
+```text
+certbot renew --dry-run：模拟续期成功
+enabled
+active
+```
+
+## 8. 域名根目录校验文件
+
+主站根目录是：
+
+```text
+/data/nginx/html/admin-ui/
+```
+
+发布第三方验证文件时，保持原始文件名和内容。例如文件名为 `example.txt`：
+
+```bash
+install -o root -g root -m 0644 /tmp/example.txt \
+  /data/nginx/html/admin-ui/example.txt
+```
+
+验证：
+
+```bash
+curl -i http://zjsjgjyyzx.cn/example.txt
+curl -i https://zjsjgjyyzx.cn/example.txt
+```
+
+两个地址都应返回：
+
+```text
+HTTP/1.1 200 OK
+```
+
+当前已发布的校验文件：
+
+```text
+/data/nginx/html/admin-ui/f7TyKy8B8f.txt
+```
+
+对应访问地址：
+
+```text
+http://zjsjgjyyzx.cn/f7TyKy8B8f.txt
+https://zjsjgjyyzx.cn/f7TyKy8B8f.txt
+```
+
+## 9. 部署后验证
+
+### 9.1 HTTP 与 HTTPS 首页
+
+```bash
+curl -I --max-time 30 http://zjsjgjyyzx.cn/
+curl -I --max-time 30 https://zjsjgjyyzx.cn/
+```
+
+两者都应返回：
+
+```text
+HTTP/1.1 200 OK
+```
+
+HTTP 不应返回 `301/302` 到 HTTPS。
+
+### 9.2 TLS 证书
+
+```bash
+printf '' | openssl s_client \
+  -connect zjsjgjyyzx.cn:443 \
+  -servername zjsjgjyyzx.cn 2>/dev/null |
+  openssl x509 -noout -subject -issuer -dates
+```
+
+预期主体：
+
+```text
+subject=CN=zjsjgjyyzx.cn
+```
+
+### 9.3 HTTPS API
+
+```bash
+curl -sS -o /dev/null -w '%{http_code} %{content_type}\n' \
+  --max-time 30 \
+  https://zjsjgjyyzx.cn/app-api/system/menu/list
+```
+
+预期：
+
+```text
+200 application/json;charset=UTF-8
+```
+
+### 9.4 Nginx 与续期
+
+```bash
+docker exec nginx nginx -t
+certbot certificates
+certbot renew --dry-run
+```
+
+## 10. 回滚
+
+### 10.1 回滚 HTTPS 配置
+
+如果 HTTPS 新配置导致 `nginx -t` 失败或业务异常：
+
+```bash
+set -e
+CFGDIR=/data/nginx/conf/conf.d
+BACKUP="$CFGDIR/zhjzpt-ssl.conf.bak-YYYYMMDDHHMMSS"
+
+test -f "$BACKUP"
+cp -p "$BACKUP" "$CFGDIR/zhjzpt-ssl.conf"
+docker exec nginx nginx -t
+docker exec nginx nginx -s reload
+```
+
+如果需要临时停用 HTTPS server：
+
+```bash
+set -e
+mv /data/nginx/conf/conf.d/zhjzpt-ssl.conf \
+  /data/nginx/conf/conf.d/zhjzpt-ssl.conf.disabled
+
+docker exec nginx nginx -t
+docker exec nginx nginx -s reload
+```
+
+这不会影响现有 HTTP 80 站点。
+
+### 10.2 回滚 HTTP 配置
+
+只在误改 `zhjzpt.conf` 时恢复：
+
+```bash
+set -e
+CFGDIR=/data/nginx/conf/conf.d
+BACKUP="$CFGDIR/zhjzpt.conf.bak-YYYYMMDDHHMMSS-before-change"
+
+test -f "$BACKUP"
+cp -p "$BACKUP" "$CFGDIR/zhjzpt.conf"
+docker exec nginx nginx -t
+docker exec nginx nginx -s reload
+```
+
+不要删除 `/data/nginx/html/admin-ui/` 整个目录，以免影响后台前端和根目录校验文件。
+
