Apache RocketMQ is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability.
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 based on DLedger Controller
- Built-in message tracing capability, also supports 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
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.
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 5.5.1 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/5.5.1/rocketmq-all-5.5.1-bin-release.zip # Unpack the release $ unzip rocketmq-all-5.5.1-bin-release.zip
Prepare a terminal and change to the extracted bin directory:
$ cd rocketmq-all-5.5.1-bin-release/bin1) 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 to 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 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, 192.168.1.2:10911] boot success...
For Windows users:
$ mqbroker.cmd -n localhost:9876 The broker[broker-a, 192.168.1.2:10911] boot success...
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 type=bind,source=/tmp/store,target=/home/rocketmq/store apache/rocketmq ./mqbroker -n localhost:9876
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 are 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 are 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
