Deploy InfluxDB for OMS

This topic describes how to deploy InfluxDB after you deploy OceanBase Migration Service (OMS) Community Edition.

Limitations

• You can deploy only one InfluxDB instance for OMS Community Edition, regardless of whether you deploy OMS Community Edition in one or multiple regions.

• If OMS Community Edition is deployed on multiple nodes, you must deploy the same InfluxDB instance on all nodes.

Procedure

1. Deploy InfluxDB.

   Deploy InfluxDB and verify that the service is available. For more information, see Deploy a time-series database.

2. Configure OMS Community Edition.

   Run the following command to go to the container of OMS Community Edition:

   cat /home/admin/conf/config.yaml
   

   Modify the configuration file. Here is an example:

    "tsdb_enabled": !!bool "true"
    "tsdb_password": "XXXXXX"
    "tsdb_service": "INFLUXDB"
    "tsdb_url": "influxdb_ip:influxdb_port"
    "tsdb_username": "XXXXX"
   

   You must replace the influxdb_ip and influxdb_port fields with the actual IP address and port number of your InfluxDB instance.

3. Run the sh /root/docker_init.sh command to synchronize the configurations of InfluxDB to the configuration files of components of OMS Community Edition.

   You can modify the configurations of InfluxDB in the application-oms.properties file in the /home/ds/supervisor/config/drc.properties and /home/ds/ghana/config/ directories.
