+
+### Authority Management
+
+At present, the tunnel server does not have special authority management. Users need to develop their own and authenticate the app name.
 ### Cluster Management
 
 If you want to deploy multiple tunnel servers, you can use nginx for forwarding and redis to store agent information.
 
-
+Nginx needs to configure sticky session to ensure that the user's web socket is connected to the same back-end tunnel server. The simple configuration method is to use `ip_hash`.

+
+### 权限管理
+
+目前tunnel server没有专门的权限管理，用户需要自行开发，对app name鉴权。
 ### 集群方式管理
 
 如果希望部署多台 tunnel server，可以通过nginx做转发，redis来保存agent信息。
 
+* nginx需要配置sticky session，保证用户web socket连接到同一个后端tunnel server上。简单的配置方式是用`ip_hash`。
