It offers a variety of features:

Messaging patterns including publish/subscribe, request/reply and streaming
Financial grade transactional message
Built-in fault tolerance and high availability configuration options base on DLedger Controller
Built-in message tracing capability, also support opentracing
Versatile big-data and streaming ecosystem integration
Message retroactivity by time or offset
Reliable FIFO and strict ordered messaging in the same queue
Efficient pull and push consumption model
Million-level message accumulation capacity in a single queue
Multiple messaging protocols like gRPC, MQTT, JMS and OpenMessaging
Flexible distributed scale-out deployment architecture
Lightning-fast batch message exchange system
Various message filter mechanics such as SQL and Tag
Docker images for isolated testing and cloud isolated clusters
Feature-rich administrative dashboard for configuration, metrics and monitoring
Authentication and authorization
Free open source connectors, for both sources and sinks
Lightweight real-time computing

Quick Start

This paragraph guides you through steps of installing RocketMQ in different ways. For local development and testing, only one instance will be created for each component.

Run RocketMQ locally

RocketMQ runs on all major operating systems and requires only a Java JDK version 8 or higher to be installed. To check, run java -version:

$ java -version
java version "1.8.0_121"

For Windows users, click here to download the 5.1.4 RocketMQ binary release, unpack it to your local disk, such as D:\rocketmq. For macOS and Linux users, execute following commands:

# Download release from the Apache mirror $ wget https://dist.apache.org/repos/dist/release/rocketmq/5.1.4/rocketmq-all-5.1.4-bin-release.zip

Unpack the release

$ unzip rocketmq-all-5.1.4-bin-release.zip

Prepare a terminal and change to the extracted bin directory:

$ cd rocketmq-all-5.1.4-bin-release/bin

1) Start NameServer

NameServer will be listening at 0.0.0.0:9876, make sure that the port is not used by others on the local machine, and then do as follows.

For macOS and Linux users:

### start Name Server $ nohup sh mqnamesrv &

check whether Name Server is successfully started

$ tail -f ~/logs/rocketmqlogs/namesrv.log The Name Server boot success...

For Windows users, you need set environment variables first:

From the desktop, right click the Computer icon.
Choose Properties from the context menu.
Click the Advanced system settings link.
Click Environment Variables.
Add Environment ROCKETMQ_HOME="D:\rocketmq".

Then change directory to rocketmq, type and run:

$ mqnamesrv.cmd
The Name Server boot success...

2) Start Broker

For macOS and Linux users:

### start Broker $ nohup sh bin/mqbroker -n localhost:9876 &

check whether Broker is successfully started, eg: Broker's IP is 192.168.1.2, Broker's name is broker-a

$ tail -f ~/logs/rocketmqlogs/broker.log The broker[broker-a, 192.169.1.2:10911] boot success...

For Windows users:

$ mqbroker.cmd -n localhost:9876
The broker[broker-a, 192.169.1.2:10911] boot success...

Run RocketMQ in Docker

You can run RocketMQ on your own machine within Docker containers, host network will be used to expose listening port in the container.

1) Start NameServer

$ docker run -it --net=host apache/rocketmq ./mqnamesrv

2) Start Broker

$ docker run -it --net=host --mount source=/tmp/store,target=/home/rocketmq/store apache/rocketmq ./mqbroker -n localhost:9876

Run RocketMQ in Kubernetes

You can also run a RocketMQ cluster within a Kubernetes cluster using RocketMQ Operator. Before your operations, make sure that kubectl and related kubeconfig file installed on your machine.

1) Install CRDs

### install CRDs $ git clone https://github.com/apache/rocketmq-operator $ cd rocketmq-operator && make deploy

check whether CRDs is successfully installed

$ kubectl get crd | grep rocketmq.apache.org brokers.rocketmq.apache.org 2022-05-12T09:23:18Z consoles.rocketmq.apache.org 2022-05-12T09:23:19Z nameservices.rocketmq.apache.org 2022-05-12T09:23:18Z topictransfers.rocketmq.apache.org 2022-05-12T09:23:19Z

check whether operator is running

$ kubectl get pods | grep rocketmq-operator rocketmq-operator-6f65c77c49-8hwmj 1/1 Running 0 93s

2) Create Cluster Instance

### create RocketMQ cluster resource $ cd example && kubectl create -f rocketmq_v1alpha1_rocketmq_cluster.yaml

check whether cluster resources is running

$ kubectl get sts NAME READY AGE broker-0-master 1/1 107m broker-0-replica-1 1/1 107m name-service 1/1 107m
