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 5.2.0 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/5.2.0/rocketmq-all-5.2.0-bin-release.zip

# Unpack the release
$ unzip rocketmq-all-5.2.0-bin-release.zip

Prepare a terminal and change to the extracted bin directory:

$ cd rocketmq-all-5.2.0-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
