Apache Flink is a powerful stream-processing engine. It can also run Apache Beam pipelines and templates using the Flink Runner. This short guide walks you through setting up Flink on your laptop in just a few steps. Use wget to download the latest Flink 1.19 release (Scala 2.12 build): 
wget https://dlcdn.apache.org/flink/flink-1.19.3/flink-1.19.3-bin-scala_2.12.tgz

​
Step 2: Extract the Archive

Unpack the downloaded archive: 
tar -xzf flink-1.19.3-bin-scala_2.12.tgz
Navigate into the extracted directory and start a local cluster: 
cd flink-1.19.3

# Start the cluster
./bin/start-cluster.sh

​
Step 4: Verify the Cluster

Once started, open the Flink Web UI in your browser: 👉 http://localhost:8081/ If the UI loads, your local Flink cluster is up and running! 🎉
Next, try running some Langbeam templates on your Flink cluster

​
Step 5: Stop the Cluster

When you’re done, stop the cluster to free up resources: 
./bin/stop-cluster.sh
