In addition to the `mongod` command, you can also use some parameters to configure the startup behavior of the MongoDB server. The following are some commonly used parameters:

1. `--dbpath`: Specify the storage path of the database file. By default, MongoDB stores data in the `/data/db` directory, you can use this parameter to specify other paths.
