Local Installation
This documentation is for an out-of-date version of Apache Flink. We recommend you use the latest stable version.

Local Installation #

Follow these few steps to download the latest stable versions and get started.

Step 1: Download #

To be able to run Flink, the only requirement is to have a working Java 8 or 11 installation. You can check the correct installation of Java by issuing the following command:

java -version

Download the 1.13.6 release and un-tar it.

$ tar -xzf flink-1.13.6-bin-scala_2.11.tgz
$ cd flink-1.13.6-bin-scala_2.11

Step 2: Start a Cluster #

Flink ships with a single bash script to start a local cluster.

$ ./bin/start-cluster.sh
Starting cluster.
Starting standalonesession daemon on host.
Starting taskexecutor daemon on host.

Step 3: Submit a Job #

Releases of Flink come with a number of example Jobs. You can quickly deploy one of these applications to the running cluster.

$ ./bin/flink run examples/streaming/WordCount.jar
$ tail log/flink-*-taskexecutor-*.out

Additionally, you can check Flink’s Web UI to monitor the status of the Cluster and running Job.

Step 4: Stop the Cluster #

When you are finished you can quickly stop the cluster and all running components.

$ ./bin/stop-cluster.sh
