- 新增 server/git-sync/ — 监听 Gitea Webhook，push/merge 到 main 时自动 git pull - 修改 selfcheck — 移除 git pull 步骤（由 Git Sync 负责），添加 Git Sync/Wake Gate 状态检查 - 更新 README — 添加自动同步说明，更新仓库结构 - 新增 server/nginx/guanghulab-cvm.conf — 新服务器 Nginx 配置模板 解决: PR合并后代码不会自动同步到服务器的问题 冰朔只需在Gitea点合并，服务器自动更新代码

* ════════════════════════════════════════════════════════════════
|
||
* 光湖 · Git 同步服务 (Git Sync)
|
||
* 监听 Gitea Webhook，自动拉取最新代码到服务器
|
||
* ════════════════════════════════════════════════════════════════
|
||
*
|
||
* 工作原理：
|
||
* 1. Gitea 配置 Webhook → push 事件 → 通知此服务
|
||
* 2. 本服务收到通知后执行 git pull 同步代码
|
||
* 3. 同步成功后重启相关 PM2 服务
|
||
*
|
||
* 安全设计：
|
||
* - 验证 Webhook Secret（防止伪造请求）
|
||
* - 仅响应 push 到 main 分支的事件
|
||
* - 同步操作以 root 权限运行（确保 git 权限无问题）
|
||
* - 同步锁防止并发执行
|
||
* - 同步失败自动重试（最多3次）
|
||
*
|
||
* 部署位置: /data/guanghulab/server/git-sync/
|
||
* PM2 进程名: guanghulab-git-sync
|
||
* ════════════════════════════════════════════════════════════════
