Enabling IP Addresses of Shard and Config Nodes

Before You Start

• DDS supports cluster instances of Community Edition 3.4, 4.0 and 4.2.
• DDS creates two connection addresses for the primary and secondary nodes in a shard group or config group.

  The network type of the connection address is the same as that of the current mongos node.

• Once the connection addresses are assigned to your nodes, they cannot be changed or deleted.
• After you enable the connection address, you can connect to an instance using Mongo Shell.

Enabling shard IP Address

• The shard IP address cannot be changed or disabled after being enabled, and the password cannot be changed.
• Once the shard IP address is enabled, DDS automatically applies for connection addresses for all shard nodes in the current instance.
• After the shard IP address is enabled and new shard nodes are added, you need to manually locate a newly added shard node and choose More > Show shard IP Address in the Operation column to show the shard IP address.

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click in the upper left corner of the page and choose Databases > Document Database Service.
4. On the Instances page, click the instance name. The Basic Information page is displayed.

   Alternatively, you can click Connections in the navigation pane on the left to go to the Basic Information page.

5. In the Node Information area, click the shard tab.

6. Click Show shard IP Address. In the displayed dialog box, enter and confirm the password for connecting to the node.

   After the shard IP address is enabled, restart the corresponding shard node for the configuration to take effect.

   In the Node Information area, locate the row that contains the shard node and click Restart in the Operation column to restart the shard node.

7. View the private IP address of the shard node.
   After the shard IP address is enabled, you can click next to a shard node on the current page to expand the node drop-down list or click Connections in the navigation pane on the left, and then obtain the private IP address.

   Figure 4 Private IP addresses of shard nodes
   

   The connection address of the current shard node is as follows:

   mongodb://sharduser:<password>@192.168.xx.xx:8637,192.168.xx.xx:8637/test?authSource=admin&replicaSet=shard_?

   

   • sharduser is the username of the current shard node.
   • **** is the password of the current node.
   • 192.168.xx.xx and 192.168.xx.xx are the private IP addresses of the primary and secondary shard nodes.
   • 8637 is the port of the shard node and cannot be changed.
   • shard_? is the name of the shard node to be connected, for example, shard_1.

Enabling config IP Address

• The config IP address cannot be modified or disabled after being enabled, and the password cannot be modified.
• Once the config IP address is enabled, DDS automatically applies for connection addresses for all config nodes in the current instance.

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click in the upper left corner of the page and choose Databases > Document Database Service.
4. In the left navigation pane, choose Instances. In the instance list, click the instance name to go to the Basic Information page.

   Alternatively, you can click Connections in the navigation pane on the left to go to the Basic Information page.

5. In the Node Information area, click the config tab.

6. Click Show config IP Address. In the displayed dialog box, enter and confirm the password for connecting to the node.
   Figure 6 Enable config IP Address
   

   After the config IP address is enabled, the corresponding config node needs to be restarted for the configuration to take effect.

   In the Node Information area, locate the row that contains the config node and click Restart in the Operation column to restart the config node.

7. View the private IP address of the config node.
   After the config IP address is enabled, you can click next to the node on the current page to expand the node drop-down list or click Connections in the navigation pane on the left, and then obtain the private IP address.

   Figure 8 Private IP addresses of config nodes
   

   The connection address of the current config node is as follows:

   mongodb://csuser:<password>@192.168.xx.xx:8636/test?authSource=admin

   

   • csuser is the username of the current config node.
   • **** is the password of the current node.
   • 192.168.xx.xx is the private IP address of the primary config node.
   • 8636 is the port of the config node and cannot be changed.

Follow-up Operations

After the connection addresses of the shard or config nodes are enabled, you can connect to the shard or config nodes using MongoShell. For details, see Connecting to a Cluster Instance Using Mongo Shell.
