Accessing MRS Manager (Versions Earlier Than MRS 3.x)¶
Scenario¶
Clusters of versions earlier than MRS 3.x use MRS Manager to monitor, configure, and manage clusters. You can open the MRS Manager page on the MRS console.
Accessing MRS manager¶
Log in to the MRS management console.
In the navigation pane, choose Clusters > Active Clusters. Click the target cluster name to access the cluster details page.
Click Access Manager. The Access MRS Manager page is displayed.
If you have bound an EIP when creating a cluster,
Select the security group to which the security group rule to be added belongs. The security group is configured when the cluster is created.
Add a security group rule. By default, your public IP address used for accessing port 9022 is filled in the rule. To enable multiple IP address segments to access MRS Manager, see 6 to 9. If you want to view, modify, or delete a security group rule, click Manage Security Group Rule.
Note
It is normal that the automatically generated public IP address is different from the local IP address and no action is required.
If port 9022 is a Knox port, you need to enable the permission of port 9022 to access Knox for accessing MRS Manager.
Select the checkbox stating that I confirm that xx.xx.xx.xx is a trusted public IP address and MRS Manager can be accessed using this IP address.
If you have not bound an EIP when creating a cluster,
Select an available EIP from the drop-down list or click Manage EIP to create one.
Select the security group to which the security group rule to be added belongs. The security group is configured when the cluster is created.
Add a security group rule. By default, your public IP address used for accessing port 9022 is filled in the rule. To enable multiple IP address segments to access MRS Manager, see 6 to 9. If you want to view, modify, or delete a security group rule, click Manage Security Group Rule.
Note
It is normal that the automatically generated public IP address is different from the local IP address and no action is required.
If port 9022 is a Knox port, you need to enable the permission of port 9022 to access Knox for accessing MRS Manager.
Select the checkbox stating that I confirm that xx.xx.xx.xx is a trusted public IP address and MRS Manager can be accessed using this IP address.
Click OK. The MRS Manager login page is displayed.
Enter the default username admin and the password set during cluster creation, and click Log In. The MRS Manager page is displayed.
On the MRS console, click Clusters and choose Active Clusters. Click the target cluster name to access the cluster details page.
Click Add Security Group Rule on the right of EIP.
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.
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.
Click OK.
If the cluster version is MRS 1.7.2 and earlier and Kerberos authentication is not enabled for the cluster, perform the following operations:
Log in to the MRS management console.
In the navigation pane, click Clusters and choose Active Clusters. Click the target cluster name to access the cluster details page.
Click Access MRS Manager.
After logging in to the MRS management console, you can access MRS Manager. By default, user admin is used for login. You do not need to enter the password again.
If the cluster version is MRS 1.7.2 or earlier and Kerberos authentication is enabled for the cluster, see Accessing Web Pages of Open Source Components Managed in MRS Clusters > Access Using a Windows ECS in the MapReduce Service User Guide.
Granting the Permission to Access MRS Manager to Other Users¶
On the MRS console, click Clusters and choose Active Clusters. Click the target cluster name to access the cluster details page.
Click Add Security Group Rule on the right of EIP.
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.
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 1 to 4. If you want to view, modify, or delete a security group rule, click Manage Security Group Rule.
Click OK.
