This topic provides reference for configuring network access permissions during OCP deployment.

Deployment units

Deployment unit	Description
OCP-Server	Docker containing the OCP management service program
OCP-Console	OCP web management console
OCP-Agent	Agents deployed on the hosts that are managed by OCP, namely OCP-Agent and OB-Agent
OBServer	OceanBase program deployed in OCP
OBProxy	OBProxy program deployed in OCP
Backup-Agent	Backup and recovery agent deployed in OCP
Application	Application that accesses the database

Listening port list

Deployment item	Listening port	Protocol	Modification	Accessible to the following deployment units	Remarks
OCP-Server	8080	HTTP	By setting the `server.port` OCP system parameter and restart OCP.	OBServer OBProxy OCP-Console Backup-Agent	The web service of the OCP-Server listens to the port. In general, other components access OCP-Server through SLB or DNS address.
OBServer	2881	TCP	Not supported	OBProxy OCP-Server Application	1. OBServer SQL listening port. 2. We recommend that you do not use direct connection to access OBServer.
OBServer	2882	TCP	Not supported	OBServer	RPC communication port between OBServers.
OBProxy	2883	TCP	Not supported	Application OCP-Server Backup-Agent	1. OBProxy listening port. 2. Applications access OBServer through OBProxy in general.
OBProxy	2884	HTTP	Not supported	OCP-Server	Listening port of the monitoring metrics API of OBProxy.
OCP-Agent	62888	http	Not supported	OCP-Server	Listening port of the API of OCP-Agent.
OCP-Agent	62889	http	Not supported	OCP-Server	Listening port of the monitoring data of OCP-Agent.
Backup-Agent	2911	TCP	You can change the port on the backup and recovery management page on OCP-Console.	None	Local listening port of Backup-Agent for performing backup. The port is not open to external access. If the port is used by another program, the Backup-Agent program will fail to start.
Backup-Agent	2912	TCP	You can change the port on the backup and recovery management page on OCP-Console.	None	Local listening port of Backup-Agent for performing recovery. The port is not open to external access. If the port is used by another program, the Backup-Agent program will fail to start.
