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 hosts.

Deploy server port restrictions

When you install OMS on a deployment server, you must use the following ports. Before installation, make sure that the corresponding ports are available and the port policies are enabled.

• The server on which OMS is installed must provide the following ports.

  Port	Description
  8089/8090	The port for the OMS management console.
  2023	The port for the sshd service.
  8084	The port for the supervisorctl Web interface.
  8088	The port for the cluster management module of OMS. In supervisorctl, the component is named oms_drc_cm.
  9000/9001	The service port for the host Agent process.
  16000~16499 17000~17499 18000~18499 7100-7499	The random ports for internal components of OMS.

  If you need to change the port for the OMS management console, 8089, perform the following steps:

  1. Enter 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 and change 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 the server on which InfluxDB is deployed provides the InfluxDB service port, 8086, available.

NTP service

Before installation, make sure that the OMS Meta database and all OMS deployment servers are configured and enabled with the NTP service, and that the clocks of the servers are synchronized. Also, make sure that the time zones of the database and the servers are consistent.

Network connectivity

Ensure that the network is connected between the OMS deployment server, obproxy, OBServer node, OCP, and the data sources involved in the migration and synchronization.
