Accessing FusionInsight Manager (MRS 3.x or Later)

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

Scenario

In MRS 3.x or later, FusionInsight Manager is used to monitor, configure, and manage clusters. After the cluster is installed, you can use the account to log in to FusionInsight Manager.

If you cannot log in to the WebUI of the component, access FusionInsight Manager by referring to Accessing FusionInsight Manager Through an ECS.

Accessing FusionInsight Manager Using an Elastic IP Address

If the EIP address function is enabled for the cluster, perform the following steps:

  1. Log in to the MRS management console.
  2. In the navigation pane, choose Clusters > Active Clusters. Click the target cluster name to access the cluster details page.
  3. Click Manage next to MRS Manager. In the displayed dialog box, configure the EIP information.

    1. If no EIP is bound during MRS cluster creation, select an available EIP from the EIP drop-down list or click Manage EIP to purchase an EIP. If you have bound an EIP when creating a cluster, go to 3.b.
    2. Select the security group to which the security group rule to be added belongs. The security group is configured when the cluster is created.
    3. Add a security group rule. By default, the filled-in rule is used to access the EIP. To enable multiple IP address segments to access Manager, see steps 6 to 9. If you want to view, modify, or delete a security group rule, click Manage Security Group Rule.
    4. Select the information to be confirmed and click OK.

  4. Click OK. The Manager login page is displayed.
  5. Enter the default username admin and the password set during cluster creation, and click Log In. The Manager page is displayed.
  6. On the MRS management console, choose Clusters > Active Clusters. Click the target cluster name to access the cluster details page.

    To grant other users the permission to access Manager, perform 6 to 9 to add the users' public IP addresses to the trusted IP address range.

  7. Click Add Security Group Rule on the right of EIP, as shown inFigure 1.

    Figure 1 Cluster details

  8. On the Add Security Group Rule page, add the IP address segment for users to access the public network and select I confirm that the authorized object is a trusted public IP address range. Do not use 0.0.0.0/0. Otherwise, security risks may arise. See Figure 2.

    Figure 2 Adding a security group rule

    By default, the IP address used for accessing the public network is filled. You can change the IP address segment as required. To enable multiple IP address segments, repeat steps 6 to 9. If you want to view, modify, or delete a security group rule, click Manage Security Group Rule.

  9. Click OK.

Accessing FusionInsight Manager Through an ECS

  1. On the MRS management console, click Clusters.
  2. On the Active Clusters page, click the name of the specified cluster.

    Record the AZ, VPC, MRS ManagerSecurity Group of the cluster.

  3. On the homepage of the management console, choose Service List > Elastic Cloud Server to switch to the ECS management console and create an ECS.

    • The AZ, VPC, and Security Group of the ECS must be the same as those of the cluster to be accessed.
    • Select a Windows public image. For example, a standard image Windows Server 2012 R2 Standard 64bit(40GB).
    • For details about other configuration parameters, see Purchasing an ECS.

    If the security group of the ECS is different from Default Security Group of the Master node, you can modify the configuration using either of the following methods:

    • Change the security group of the ECS to the default security group of the Master node. For details, see Changing a Security Group.
    • Add two security group rules to the security groups of the Master and Core nodes to enable the ECS to access the cluster. Set Protocol to TCP, Ports of the two security group rules to 28443 and 20009, respectively. For details, see Creating a Security Group.

  4. On the VPC management console, apply for an EIP and bind it to the ECS.

    For details, see Assigning an EIP and Binding It to an ECS.

  5. Log in to the ECS.

    The Windows system account, password, EIP, and the security group rules are required for logging in to the ECS. For details, see Logging In to a Windows ECS.

  6. On the Windows remote desktop, use your browser to access Manager.

    For example, you can use Internet Explorer 11 in the Windows 2012 OS.

    The address for accessing Manager is the address of the MRS Manager page. Enter the name and password of the cluster user, for example, user admin.

    • If you access Manager with other cluster usernames, change the password upon your first access. The new password must meet the requirements of the current password complexity policies. For details, contact the administrator.
    • By default, a user is locked after inputting an incorrect password five consecutive times. The user is automatically unlocked after 5 minutes.

  7. Log out of FusionInsight Manager. To log out of Manager, move the cursor to in the upper right corner and click Log Out.
