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`: ```shell $ java -version java version "1.8.0_121" ``` For Windows users, click [here](https://archive.apache.org/dist/rocketmq/4.9.3/rocketmq-all-4.9.3-bin-release.zip) to download the 4.9.3 RocketMQ binary release, unpack it to your local disk, such as `D:\rocketmq`. For macOS and Linux users, execute following commands: ```shell # Download release from the Apache mirror $ wget https://archive.apache.org/dist/rocketmq/4.9.3/rocketmq-all-4.9.3-bin-release.zip # Unpack the release $ unzip rocketmq-all-4.9.3-bin-release.zip ``` Prepare a terminal and change to the extracted `bin` directory: ```shell $ cd rocketmq-4.9.3/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: ```shell ### 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: ```shell $ mqnamesrv.cmd The Name Server boot success... ``` **2) Start Broker** For macOS and Linux users: ```shell ### 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: ```shell $ 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** ```shell $ docker run -it --net=host apache/rocketmq ./mqnamesrv ``` **2) Start Broker** ```shell $ 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](https://github.com/apache/rocketmq-operator). Before your operations, make sure that `kubectl` and related kubeconfig file installed on your machine. **1) Install CRDs** ```shell ### 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** ```shell ### 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 ``` --- ## Apache RocketMQ Community * [RocketMQ Streams](https://github.com/apache/rocketmq-streams): A lightweight stream computing engine based on Apache RocketMQ. * [RocketMQ Flink](https://github.com/apache/rocketmq-flink): The Apache RocketMQ connector of Apache Flink that supports source and sink connector in data stream and Table. * RocketMQ Muli-Language Clients - [RocketMQ Client CPP](https://github.com/apache/rocketmq-client-cpp) - [RocketMQ Client Go](https://github.com/apache/rocketmq-client-go) - [RocketMQ Client Python](https://github.com/apache/rocketmq-client-python) - [RocketMQ Client Nodejs](https://github.com/apache/rocketmq-client-nodejs) * [RocketMQ Spring](https://github.com/apache/rocketmq-spring): A project which helps developers quickly integrate Apache RocketMQ with Spring Boot. * [RocketMQ Exporter](https://github.com/apache/rocketmq-exporter): An Apache RocketMQ exporter for Prometheus. * [RocketMQ Operator](https://github.com/apache/rocketmq-operator): Providing a way to run an Apache RocketMQ cluster on Kubernetes. * [RocketMQ Docker](https://github.com/apache/rocketmq-docker): The Git repo of the Docker Image for Apache RocketMQ. * [RocketMQ Dashboard](https://github.com/apache/rocketmq-dashboard): Operation and maintenance console of Apache RocketMQ. * [RocketMQ Connect](https://github.com/apache/rocketmq-
