Overview:

You can start the control instance through the configuration file when you start mongod and mongos.

The configuration file contains settings equal to the mongod and mongos command options.

It is easier to manage mongod and mongos using configuration files, especially for large-scale deployments.

You can also add comments to the configuration file to explain the server settings options.

Use profile:

To start mongod and mongos, use the configuration file, which is specified with the-config or-f option.
