System and network requirements

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

Operating system

OMS can be deployed only on Linux-based servers.

Ports

The following table describes the ports required for deploying OMS on a server. Before deployment, make sure that these ports are unoccupied and that the port strategies are enabled.

• The server where OMS is to be deployed must provide the following ports.

  Port	Description
  8089/8090	The ports used to connect to the OMS console.
  2023	The SSHD service port.
  8084	The port used to access the web page of supervisorctl.
  8088	The port used to connect to the OMS cluster management (CM) module, whose name is oms_drc_cm in supervisorctl.
  9000/9001	The ports for the agent process of the host.
  16000-16499 17000-17499 18000-18499 7100-7499	The ports that are randomly allocated to OMS components.

• To change a port number, perform the following steps:

  1. Go to the Docker container.

     docker exec -it ${CONTAINER_NAME} bash
     

     Note

     CONTAINER_NAME specifies the name of the container.

  2. Run the vi /home/ds/ghana/config/tengine.conf command to change the port number behind the listen parameter.

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

  4. Run the supervisorctl restart nginx command.

• If InfluxDB is deployed, make sure that port 8086 is available for InfluxDB on the host where InfluxDB is deployed.

NTP service

Before you deploy OMS, make sure that the NTP service is provided and enabled on the OMS MetaDB and all OMS hosts, clocks of hosts are synchronized, and the database time zone and host time zone are consistent.

Network connectivity

Make sure that the OMS hosts are connected to OBProxies, OBServer nodes, OceanBase Cloud Platform (OCP), and data sources involved in migration or synchronization.
