System and network requirements

This topic describes the system and network requirements for installing OceanBase Migration Service (OMS).

Operating system

OMS can be deployed only on Linux-based servers.

Deploy OMS and configure port limits

When you deploy OMS, make sure that the following ports are available and the corresponding port policies are enabled.

• The following ports must be available on the server where OMS is deployed.

  Port	Description
  8089/8090	The port for the OMS management console.
  8084	In a single-node deployment: the port for the supervisorctl Web interface. In a separated deployment: the port for the supervisorctl Web interface of the management node.
  9084	In a single-node deployment: this port is not required. In a separated deployment: the port for the supervisorctl Web interface of the component node.
  8088	The port for the OMS cluster management module, which is named oms_drc_cm in supervisorctl.
  9000/9001	The port for the Host Agent process.
  16000~16499 17000~17499 18000~18499 7100-7499	The random ports for internal components of OMS.

  To modify the external port 8089 of the OMS management console, perform the following steps:

  1. Log in to the Docker container.

     docker exec -it ${CONTAINER_NAME} bash
     

     Note

     CONTAINER_NAME is the name of the container.

  2. Run the vi /home/ds/ghana/config/tengine.conf command to modify the port number after the listen parameter in this file.

     

  3. Enter :wq and press Enter to save the changes and exit the editing mode.

  4. Run the supervisorctl restart nginx command.

• If you have deployed InfluxDB, make sure that port 8086 for the InfluxDB service is available on the server where InfluxDB is deployed.

NTP service

Before installation, make sure that the OMS Meta database and all OMS deployment servers have the NTP service configured and enabled, and that the clocks are synchronized between the servers. Also, ensure that the database time zone and server time zone are consistent.

Network connectivity

Ensure that the OMS deployment servers, obproxy, OBServer nodes, OCP, and data sources involved in migration and synchronization have network connectivity.
