Management Cluster Configuration

Updated at: Mar 25, 2021 GMT+08:00

Scenario

FusionInsight Manager allows you to view the changes of service configuration parameters in a cluster by one click, helping you quickly locate faults and improve configuration management efficiency.

Administrators can quickly view all non-default values of each service in the cluster, non-unified values between instances of the same role, historical records of cluster configuration modification, and parameters whose configuration status is expired in the cluster on the configuration page.

Procedure

  1. Log in to FusionInsight Manager.
  2. Choose Cluster > Name of the desired cluster > Configurations.
  3. Select an operation page based on the scenario.

    • To view all non-default values:
      1. Click All Non-default Values. The system displays the parameters that are inconsistent with the default values of each service, role, or instance in the current cluster.

        You can click next to a parameter value to quickly restore to the default value. You can click to view the historical modification records of the parameter.

        If a large number of parameters need to be configured, you can filter the parameters in the service filter box in the upper right corner of the page or enter keywords in the search box to search for the parameters.

      2. If you need to change the parameter values of the configuration items, change the values according to the parameter description, and then click Save. In the dialog box that is displayed, click OK.
    • To view all non-unified values:
      1. Click All Non-uniform Values. The system displays configuration items with different role, instance group, service, or instance configurations in the current cluster.

        Click next to the parameter value. In the window that is displayed, you can view the differences.

      2. If you need to change the parameter values, click to cancel the configuration difference or manually adjust the parameter values, click OK, and then click Save. In the dialog box that is displayed, click OK.
    • To check the expiration configurations:
      1. Click Expired Configurations. Expired configuration items in the current cluster are displayed.
      2. You can filter services in the upper corner of the page to view the expired configurations of different services, or enter keywords in the search box.
      3. The expired configuration items do not take effect completely. If services are not affected, restart the services or instances whose configuration items have expired.
    • To view historical configuration records:
      1. Click Historical Configurations. The historical configuration change records of the current cluster are displayed. You can view the parameter value change details, including the service to which the parameter belongs, parameter values before and after the modification, and parameter files.
      2. To restore a configuration change, click Restore Configuration in the Operation column. In the dialog box that is displayed, click OK.

    Some configuration items take effect only after the corresponding services are restarted. After the configuration is saved, restart the service or instance whose configuration has expired in a timely manner.
