Accessing FusionInsight Manager (MRS 3.x or Later)

Scenario

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

Currently, you can access FusionInsight Manager using the following methods:

• Accessing FusionInsight Manager Using EIP
• Accessing FusionInsight Manager Using Direct Connect
• Accessing FusionInsight Manager from an ECS

You can switch the access methods between EIP and Direct Connect on the MRS console by performing the following steps:

Log in to the MRS management console and click the desired cluster. On the displayed page, click next to MRS Manager on the Dashboard tab, and switch the access method.

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

FusionInsight Manager cannot be accessed when the cluster is in any of the following states:

Starting, Stopping, Stopped, Deleting, Deleted, and Frozen.

Accessing FusionInsight Manager Using EIP

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 Manager 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 drop-down list on the right of IEP. If you have bound an EIP when you create a cluster, go to 3.b.
      

      • If no EIPs are available, click Manage EIP to buy one. Then, select the EIP from the drop-down list.
      • To unbind or release an EIP after using it, log in to the EIPs page, locate the row containing the target EIP, and click Unbind or choose More > Release in the Operation column.
      • If an EIP has been created but cannot be found during binding, the EIP may have been bound to another cluster. In this case, unbind the EIP on the EIPs page and then bind it to the current cluster.
   2. In Security Group, select the security group to which the current cluster belongs. The security group is configured during cluster creation or is automatically created by the cluster.
      

      • When creating a custom cluster, you can configure a security group created in advance or retain the default value Auto create. When you quickly create a cluster, the security group is automatically created by the cluster.
      • You can view the security group name in Security Group on the Dashboard tab page of the cluster.
   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.
      

      "MRS Manager public ip access control rule" is added to the Description column of the the security group rule you added. To view this description, choose Manage Security Group Rule, click Security Group, and click the Inbound Rules tab.

      

   4. Select the information to be confirmed and click OK.
      

      Click on the right of Access Manager to change the FusionInsight Manager access mode. For details about how to access FusionInsight Manager by using Direct Connect, see Accessing FusionInsight Manager by Using Direct Connect.

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 next to EIP.
   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 public network IP/port is a trusted public IP address. I understand that using 0.0.0.0/0. poses security risks. 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 by Using Direct Connect

You need to ensure that Direct Connect is available, and the connection between the local data center and the online VPC has been established.

1. Log in to the MRS console.
2. Click the name of the cluster to enter its details page.
3. On the Dashboard tab page of the cluster details page, click Access Manager next to MRS Manager.
4. Set Access Mode to Direct Connect and select I confirm that the network between the local PC and the floating IP address is connected and that MRS Manager is accessible using the Direct Connect connection.

   The floating IP address is automatically allocated by MRS to access MRS Manager. Before using Direct Connect to access MRS Manager, ensure that the connection between the local data center and the online VPC has been established.

   

5. Click OK. The MRS Manager login page is displayed. Enter the username admin and the password set during cluster creation.

Accessing FusionInsight Manager from 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 with Customized Configurations.
   

   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.

   If "Failed to add security group rules." is displayed, check whether the security group quota is sufficient. If more quotas are needed, increase the quotas or delete security group rules that are no longer used.

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 security group rules are required for logging in to the ECS.

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

   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.
