Access Using a Windows ECS

MRS allows you to access the web UIs of open-source components through a Windows ECS. This method is complex and is recommended for MRS clusters that do not support the EIP function (security clusters with Kerberos authentication enabled in versions earlier than MRS 1.9.2).

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

   On the cluster details page, record the AZ, VPC, Cluster Manager IP Address, and Security Group of the cluster.

   

   To obtain the cluster manager IP address, remotely log in to the Master2 node, and run the ifconfig command. In the command output, eth0:wsom indicates the cluster manager IP address. Record the value of inet. If the cluster manager IP address cannot be queried on the Master2 node, switch to the Master1 node to query and record the cluster manager IP address. If there is only one Master node, query and record the cluster manager IP address of the Master node.

3. On the ECS management console, 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, select the enterprise image Enterprise_Windows_STD_2012R2_20170316-0(80GB).
   • For details about other configuration parameters, see Elastic Cloud Server > User Guide > Getting Started > Creating and Logging In to a Windows ECS.
   

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

   • Change the security group of the ECS to the security group of the MRS cluster. For details, see Elastic Cloud Server > User Guide > Security Group > 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 and ports of the two security group rules to 28443 and 20009, respectively. For details, see Virtual Private Cloud > User Guide > Security > Security Group > Adding a Security Group Rule.

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

   For details, see Virtual Private Cloud > User Guide > Elastic IP > 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 Elastic Cloud Server > User Guide > Instances > 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 MRS Manager access address is in the format of https://Cluster Manager IP Address:28443/web. Enter the name and password of the MRS cluster user, for example, user admin.

   

   • To obtain the cluster manager IP address, remotely log in to the Master2 node, and run the ifconfig command. In the command output, eth0:wsom indicates the cluster manager IP address. Record the value of inet. If the cluster manager IP address cannot be queried on the Master2 node, switch to the Master1 node to query and record the cluster manager IP address. If there is only one Master node, query and record the cluster manager IP address of the Master node.
   • If you access MRS Manager with other MRS cluster usernames, change the password upon your first access. The new password must meet the requirements of the current password complexity policies.
   • By default, a user is locked after inputting an incorrect password five consecutive times. The user is automatically unlocked after 5 minutes.

7. Visit the web UIs of the open-source components by referring to the addresses listed in Web UIs of Open Source Components.
