Microservices Engine:Manage an instance

Last Updated:Nov 13, 2024

After you create a Microservices Engine (MSE) instance, you can view the status and other information of the instance, change the name of the instance, and release the instance if you no longer use the instance. This topic describes how to manage an MSE Nacos instance or an MSE ZooKeeper instance.

Prerequisites

Prerequisites

  • MSE is activated. If you do not activate MSE, you can activate it on the product page.

  • An instance is created. For more information, see Create an instance.

View an instance

  1. Log on to the MSE console, and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, click the name of the instance.

  4. On the Basic Information page, view the instance information, including the basic information and node status of the instance.

Change the name of an instance

After you create an instance, a name is automatically generated for the instance. To easily identify the instance, we recommend that you change the name of the instance.

  1. Log on to the MSE console, and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, click the name of the instance.

  4. On the Basic Information page, click the MSE修改图标 icon next to the Instance name to edit the instance name. Then, click OK.

Restart an instance

If an issue occurs on an instance or after you modify the parameters of an instance, you must restart the instance. You can restart one or all nodes of an instance based on your business requirements.

Restart all nodes

  1. Log on to the MSE console, and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, click the name of the instance.

  4. In the upper part of the Basic Information page, click Restart Instance. In the Restart Instance message, click OK.

    Note
    • During the restart process, a rolling upgrade is performed on all nodes. The upgrade of each node takes about 1 to 2 minutes. We recommend that you perform this operation during off-peak hours to reduce business risks.

    • If the nodes of your instance are deployed in the same zone, MSE automatically redeploys the nodes across zones after the instance is restarted. This ensures the high availability of your instance. For more information, see Redeploy nodes across zones.

Restart a single node

  1. Log on to the MSE console, and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, click the name of the instance.

  4. In the Instance node section of the Basic Information page, find the node that you want to restart and click Restart in the Actions column. In the message that appears, click OK.

Release an instance

If an instance is released, all nodes of the instance are released.

Important
  • You can manually release pay-as-you-go instances.

  • After an instance is released, the instance and its data are deleted. Proceed with caution.

  1. Log on to the MSE console, and select a region in the top navigation bar.

  2. In the left-side navigation pane, choose Microservices Registry > Instances.

  3. On the Instances page, find the MSE instance that you want to release and choose More > Release Instance in the Actions column. In the Release Instance message, click OK.
