This topic describes how to add a mongos node to an ApsaraDB for MongoDB sharded cluster
instance.
Precautions
- If the minor version of a sharded cluster instance expires or is not included in the
maintenance list, ApsaraDB for MongoDB automatically updates the minor version of
the instance to the latest version during a configuration change. This ensures that
the sharded cluster instance can provide higher performance and higher stability.
- When mongos nodes are added, no transient connections occur and your business continues
to run as expected.
- Typically, mongos nodes are added within 5 minutes. The time it takes to add mongos
nodes is not dependent on the number of mongos nodes being added.
Procedure
- Log on to the ApsaraDB for MongoDB console.
- In the upper-left corner of the page, select the resource group and the region of
the target instance.
- In the left-side navigation pane, click Sharded Cluster Instances.
- Find the target instance and click its ID.
- In the Mongos List section of the Basic Information page, click Add Mongos.
- In the Add Mongos panel, set the following parameters.

sharded cluster instance already has three mongos nodes and you want to add more mongos
nodes, you can add a maximum of 29 mongos nodes to the sharded cluster instance. If
you need more than 32 mongos nodes in a sharded cluster instance, submit a ticket.
