# Set up a standalone Pulsar locally

For local development and testing, you can run Pulsar in standalone mode on your machine. The standalone mode includes a Pulsar broker, the necessary ZooKeeper and BookKeeper components running inside of a single Java Virtual Machine (JVM) process.

#### Pulsar in production?​

If you're looking to run a full production Pulsar installation, see the Deploying a Pulsar instance guide.

## Install Pulsar standalone​

This tutorial guides you through every step of the installation process.

### System requirements​

Currently, Pulsar is available for 64-bit macOS, Linux, and Windows. To use Pulsar, you need to install 64-bit JRE/JDK 8 or later versions.

tip

By default, Pulsar allocates 2G JVM heap memory to start. It can be changed in conf/pulsar_env.sh file under PULSAR_MEM. This is extra options passed into JVM.

note

Broker is only supported on 64-bit JVM.

### Install Pulsar using binary release​

To get started with Pulsar, download a binary tarball release in one of the following ways:

After you download the tarball, untar it and use the cd command to navigate to the resulting directory:

$tar xvfz apache-pulsar-2.5.1-bin.tar.gz$ cd apache-pulsar-2.5.1

The Pulsar binary package initially contains the following directories:

DirectoryContains
binPulsar's command-line tools, such as pulsar and pulsar-admin.
confConfiguration files for Pulsar, including broker configuration, ZooKeeper configuration, and more.
examplesA Java JAR file containing Pulsar Functions example.
libThe JAR files used by Pulsar.
licensesLicense files, in the.txt form, for various components of the Pulsar codebase.

These directories are created once you begin running Pulsar.

DirectoryContains
dataThe data storage directory used by ZooKeeper and BookKeeper.
instancesArtifacts created for Pulsar Functions.
logsLogs created by the installation.
tip

If you want to use builtin connectors and tiered storage offloaders, you can install them according to the following instructions：

### Install builtin connectors (optional)​

Since 2.1.0-incubating release, Pulsar releases a separate binary distribution, containing all the builtin connectors. To enable those builtin connectors, you can download the connectors tarball release in one of the following ways:

After you download the nar file, copy the file to the connectors directory in the pulsar directory. For example, if you download the pulsar-io-aerospike-2.5.1.nar connector file, enter the following commands:

$mkdir connectors$ mv pulsar-io-aerospike-2.5.1.nar connectors$ls connectorspulsar-io-aerospike-2.5.1.nar... note • If you are running Pulsar in a bare metal cluster, make sure connectors tarball is unzipped in every pulsar directory of the broker (or in every pulsar directory of function-worker if you are running a separate worker cluster for Pulsar Functions). • If you are running Pulsar in Docker or deploying Pulsar using a docker image (e.g. K8S or DC/OS), you can use the apachepulsar/pulsar-all image instead of the apachepulsar/pulsar image. apachepulsar/pulsar-all image has already bundled all builtin connectors. ### Install tiered storage offloaders (optional)​ tip Since 2.2.0 release, Pulsar releases a separate binary distribution, containing the tiered storage offloaders. To enable tiered storage feature, follow the instructions below; otherwise skip this section. To get started with tiered storage offloaders, you need to download the offloaders tarball release on every broker node in one of the following ways: After you download the tarball, untar the offloaders package and copy the offloaders as offloaders in the pulsar directory: $ tar xvfz apache-pulsar-offloaders-2.5.1-bin.tar.gz// you will find a directory named apache-pulsar-offloaders-2.5.1 in the pulsar directory// then copy the offloaders$mv apache-pulsar-offloaders-2.5.1/offloaders offloaders$ ls offloaderstiered-storage-jcloud-2.5.1.nar

For more information on how to configure tiered storage, see Tiered storage cookbook.

note
• If you are running Pulsar in a bare metal cluster, make sure that offloaders tarball is unzipped in every broker's pulsar directory.
• If you are running Pulsar in Docker or deploying Pulsar using a docker image (e.g. K8S or DC/OS), you can use the apachepulsar/pulsar-all image instead of the apachepulsar/pulsar image. apachepulsar/pulsar-all image has already bundled tiered storage offloaders.

## Start Pulsar standalone​

Once you have an up-to-date local copy of the release, you can start a local cluster using the pulsar command, which is stored in the bin directory, and specifying that you want to start Pulsar in standalone mode.

$bin/pulsar standalone If you have started Pulsar successfully, you will see INFO-level log messages like this: 2017-06-01 14:46:29,192 - INFO - [main:WebSocketService@95] - Configuration Store cache started2017-06-01 14:46:29,192 - INFO - [main:AuthenticationService@61] - Authentication is disabled2017-06-01 14:46:29,192 - INFO - [main:WebSocketService@108] - Pulsar WebSocket Service started tip • The service is running on your terminal, which is under your direct control. If you need to run other commands, open a new terminal window. You can also run the service as a background process using the pulsar-daemon start standalone command. For more information, see pulsar-daemon. • By default, there is no encryption, authentication, or authorization configured. Apache Pulsar can be accessed from remote server without any authorization. Please do check Security Overview document to secure your deployment. • When you start a local standalone cluster, a public/default namespace is created automatically. The namespace is used for development purposes. All Pulsar topics are managed within namespaces. For more information, see Topics. ## Use Pulsar standalone​ Pulsar provides a CLI tool called pulsar-client. The pulsar-client tool enables you to consume and produce messages to a Pulsar topic in a running cluster. ### Consume a message​ The following command consumes a message with the subscription name first-subscription to the my-topic topic: $ bin/pulsar-client consume my-topic -s "first-subscription"

If the message has been successfully consumed, you will see a confirmation like the following in the pulsar-client logs:

09:56:55.566 [pulsar-client-io-1-1] INFO  org.apache.pulsar.client.impl.MultiTopicsConsumerImpl - [TopicsConsumerFakeTopicNamee2df9] [first-subscription] Success subscribe new topic my-topic in topics consumer, partitions: 4, allTopicPartitionsNumber: 4
tip

As you have noticed that we do not explicitly create the my-topic topic, from which we consume the message. When you consume a message from a topic that does not yet exist, Pulsar creates that topic for you automatically. Producing a message to a topic that does not exist will automatically create that topic for you as well.

### Produce a message​

The following command produces a message saying hello-pulsar to the my-topic topic:

\$ bin/pulsar-client produce my-topic --messages "hello-pulsar"

If the message has been successfully published to the topic, you will see a confirmation like the following in the pulsar-client logs:

13:09:39.356 [main] INFO  org.apache.pulsar.client.cli.PulsarClientTool - 1 messages successfully produced

## Stop Pulsar standalone​

Press Ctrl+C to stop a local standalone Pulsar.

tip

If the service runs as a background process using the pulsar-daemon start standalone command, then use the pulsar-daemon stop standalone command to stop the service. For more information, see pulsar-daemon.
