 Once you appropriately modify the `metadataServiceUri` parameter, you can make any other configuration changes that you require. You can find a full listing of the available BookKeeper configuration parameters [here](reference-configuration.md#bookkeeper). However, consulting the [BookKeeper documentation](https://bookkeeper.apache.org/docs/next/reference/config/) for a more in-depth guide might be a better choice.
 
 Once you apply the desired configuration in `conf/bookkeeper.conf`, you can start up a bookie on each of your BookKeeper hosts. You can start up each bookie either in the background, using [nohup](https://en.wikipedia.org/wiki/Nohup), or in the foreground.
