Then install redpanda

sudo apt install redpanda

When Redpanda is installed, it is set to run in development mode. To get the most out of the fastest queue in the west, enable production mode by running the following:

sudo rpk redpanda mode production

followed by:

sudo rpk tune all

This will autotune your system to give you the best performance from Redpanda.

# Start and Enable redpanda

Start

sudo systemctl start redpanda

Verify that Redpanda is up and running:

$ sudo systemctl status redpanda

Now enable redpanda on boot

sudo systemctl enable redpanda

Congratulations, You now have a single-node cluster running Redpanda. The cluster will run on port :9092 and you can access it like you would access kafka.

# Installing rpk

Redpanda Keeper (rpk) is a single binary application that provides a way to interact with your Redpanda clusters from the command line.

You can install rpk as part of a bundle that includes redpanda , or you can install the rpk binary separately.

To install the rpk binary as a standalone application, download the rpk archive:

curl -LO https://github.com/redpanda-data/redpanda/releases/latest/download/rpk-linux-amd64.zip

Ensure that you have the folder ~/.local/bin:

mkdir -p ~/.local/bin

Add it to your $PATH:

export PATH="~/.local/bin:$PATH"

Unzip the rpk files to your ~/.local/bin/ directory:

unzip rpk-linux-amd64.zip -d ~/.local/bin/

After the files have been unzipped, run rpk version to display the rpk binary version.

rpk version

The output displays the version number. For example:

v22.3.4 (rev 5be3e8e)

# Install Redpanda Console

To connect Redpanda Console to a Kafka cluster running on your local machine or in another Docker container:

docker run --network=host \<br>  -e KAFKA_BROKERS=localhost:9092 \<br>  docker.redpanda.com/vectorized/console:latest

To connect Redpanda Console to a remote Kafka cluster:

docker run -p 8080:8080 \<br>  -e KAFKA_BROKERS=bootstrap.cluster-hash.redpanda.cloud:9092 \<br>  -e KAFKA_TLS_ENABLED=true \<br>  -e KAFKA_SASL_ENABLED=true \<br>  -e KAFKA_SASL_MECHANISM=SCRAM-SHA-256 \<br>  -e KAFKA_SASL_USERNAME=xxx \<br>  -e KAFKA_SASL_PASSWORD=xxx \<br>  docker.redpanda.com/vectorized/console:latest

To install the Redpanda Console package on Debian/Ubuntu, run the following commands:

curl -1sLf \<br>  'https://dl.redpanda.com/nzc4ZYQK3WRGd9sy/redpanda/cfg/setup/bash.deb.sh' \<br>  | sudo -E bash<br>  <br>sudo apt-get install redpanda-console

Start the console

sudo systemctl start redpanda-console

The console will run in port 8080 and you can access it in your browser.

That is it, enjoy your Redpanda installation.
