## database.backend, database.host, database.port, database.name & database.replicaset ## database.backend, database.host, database.port, database.name & database.replicaset
The database backend to use (e.g. RethinkDB) and its hostname, port and name. The database backend to use (`rethinkdb` or `mongodb`) and its hostname, port and name. If the database backend is `mongodb`, then there's a fifth setting: the name of the replica set. If the database backend is `rethinkdb`, you *can* set the name of the replica set, but it won't be used for anything.
**Example using environment variables** **Example using environment variables**
```text ```text
export BIGCHAINDB_DATABASE_BACKEND=rethinkdb export BIGCHAINDB_DATABASE_BACKEND=mongodb
export BIGCHAINDB_DATABASE_HOST=localhost export BIGCHAINDB_DATABASE_HOST=localhost
export BIGCHAINDB_DATABASE_PORT=28015 export BIGCHAINDB_DATABASE_PORT=27017
export BIGCHAINDB_DATABASE_NAME=bigchain export BIGCHAINDB_DATABASE_NAME=bigchain
export BIGCHAINDB_DATABASE_REPLICASET=bigchain-rs export BIGCHAINDB_DATABASE_REPLICASET=bigchain-rs
``` ```
Note: If the backend database is RethinkDB, you *can* set `BIGCHAINDB_DATABASE_REPLICASET` but it won't be used for anything.

If (no environment variables were set and there's no local config file), or you used `bigchaindb -y configure rethinkdb` to create a default local config file for a RethinkDB backend, then the defaults will be: If (no environment variables were set and there's no local config file), or you used `bigchaindb -y configure rethinkdb` to create a default local config file for a RethinkDB backend, then the defaults will be:
