rocketmq 安装启动

首先，查看官方文档 http://rocketmq.apache.org/docs/quick-start/

Prerequisite

The following softwares are assumed installed:

1. 64bit OS, Linux/Unix/Mac is recommended;
2. 64bit JDK 1.8+;
3. Maven 3.2.x
4. Git

Download & Build from Release

Click here to download the 4.3.0 source release. Also you could download a binary release from here.

Now execute the following commands to unpack 4.3.0 source release and build the binary artifact.

  > unzip rocketmq-all-4.3.0-source-release.zip
  > cd rocketmq-all-4.3.0/
  > mvn -Prelease-all -DskipTests clean install -U
  > cd distribution/target/apache-rocketmq

Start Name Server

  > nohup sh bin/mqnamesrv &
  > tail -f ~/logs/rocketmqlogs/namesrv.log
  The Name Server boot success..

Start Broker

  > nohup sh bin/mqbroker -n localhost:9876 &
  > tail -f ~/logs/rocketmqlogs/broker.log 
  The broker[%s, 172.30.30.233:10911] boot success...

在启动过程中，如果不修改默认配置，系统会卡死，报错

内存不足，调整bin/runserver.sh

调整如下

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

调整bin/runbroker.sh

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m"

 调整bin/tools.sh

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m"

Send & Receive Messages

Before sending/receiving messages, we need to tell clients the location of name servers. RocketMQ provides multiple ways to achieve this. For simplicity, we use environment variable NAMESRV_ADDR

 > export NAMESRV_ADDR=localhost:9876
 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
 SendResult [sendStatus=SEND_OK, msgId= ...

 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
 ConsumeMessageThread_%d Receive New Messages: [MessageExt...

Shutdown Servers

> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK
