 ## Linux 部署

 - `deploy/ops-licence.service`
-- `deploy/nginx.conf`
+- `deploy/ops-license-ca.conf`（Caddy）

 ### 文件位置
 
 建议按模板放置：
 
 ```text
-/usr/local/bin/ops-licence
-/etc/ops-licence/ops-licence.yaml
-/etc/ops-licence/keys/signing-private.pem
-/etc/ops-licence/keys/signing-certificate.json

+/data/app/ops-licence
+/data/app/etc/license.yaml
+/data/app/etc/signing-private.pem
+/data/app/etc/signing-certificate.json
 ```
 
 Linux YAML 示例：
 
 ```yaml
 server:
-  listen_addr: "127.0.0.1:8080"
+  listen_addr: "127.0.0.1:14522"
 
 database:
   dsn: "postgresql://username:password@database-host:5432/ops_licence?sslmode=disable"
 
 signing:

+  private_key_file: "/data/app/etc/signing-private.pem"
+  certificate_file: "/data/app/etc/signing-certificate.json"
 ```

-`deploy/nginx.conf` 将 HTTPS 请求反向代理到 `127.0.0.1:8080`。部署时将其中证书路径替换为实际路径，并把配置放入 Nginx 的站点配置目录后重新加载 Nginx。
+`deploy/ops-license-ca.conf` 将 `licence.apinb.com` 的 HTTPS 请求反向代理到 `127.0.0.1:14522`，并使用本地证书文件。部署时按实际域名和证书路径修改后，并入主 Caddyfile 或单独加载：
 
-Go 可执行文件已经包含前端资源，Nginx 只需要代理所有路径，不需要另外复制 `web/dist`。

 ## Go SDK 接入
 
 将整个 `sdk/licence` 目录复制到目标 Go 项目中，保持目录内所有文件完整。目标项目不需要连接许可证管理系统。
