# Install and Configure ksqlDB for Confluent Platform ksqlDB is available as part of Confluent Platform and Confluent Cloud, or as a standalone Docker installation. For Confluent Platform, the binaries are included in the Confluent Platform bundle available at [https://www.confluent.io/download/](https://www.confluent.io/download/), and require access to a running Apache Kafka® cluster. You can also install ksqlDB individually using the Docker images available at [Docker Hub](https://hub.docker.com/r/confluentinc/cp-ksqldb-server/). ## Start the ksqlDB Server The command to start the server is `ksql-server-start ${CONFLUENT_HOME}/etc/ksqldb/ksql-server.properties.` You must specify [configuration parameters](server-config.md#ksqldb-install-configure-server), including required parameters like `bootstrap.servers` and `listeners`. You can set these in the ksqlDB properties file or the `KSQL_OPTS` environment variable, which takes precedence. The default settings are `bootstrap.servers=localhost:9092` and `listeners=http://0.0.0.0:8088`. Confluent Control Center can also be configured to interact with ksqlDB Server. This involves settings like `confluent.controlcenter.ksql..url` and `confluent.controlcenter.ksql..advertised.url`. Ensure these URLs are reachable from the Confluent Control Center machine and any browser using the ksqlDB web interface. There are also settings for HTTP Basic Authentication and Secure Sockets Layer (SSL) configuration. ## Start the ksqlDB Command Line Interface (CLI) Start the CLI by using the `ksql` command provided with the Confluent Platform distribution. The CLI provides options like `--output` to specify the output format (JSON or TABULAR), and `--password` or `-p` for authentication, if configured. ## Confluent Cloud configuration To use ksqlDB with Confluent Cloud, see [Manage ksqlDB on Confluent Cloud](/cloud/current/cp-component/ksqldb-ccloud-cli.html). - [Install ksqlDB](installing.md#ksqldb-install) - [Configure ksqlDB with Docker](install-ksqldb-with-docker.md#ksqldb-install-configure-with-docker) - [Check the Health of a ksqlDB Server](check-ksqldb-server-health.md#ksqldb-install-check-server-health) - [Configure ksqlDB Server](server-config.md#ksqldb-install-configure-server) - [Configure ksqlDB CLI](cli-config.md#ksqldb-install-configure-cli) - [Upgrade ksqlDB](upgrading.md#ksqldb-installation-upgrade) - [Configure Serialization-Formats](avro-schema.md#ksqldb-installation-configure-serialization-formats) - [Configure Security](security.md#ksqldb-installation-security)
