1、下载

下载地址：https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.3.2/rocketmq-all-4.3.2-bin-release.zip
版本使用目前最新版：4.3.2

2、非Docker安装

cd /haoke
unzip rocketmq-all-4.3.2-bin-release.zip
cd rocketmq-all-4.3.2-bin-release
#启动nameserver
bin/mqnamesrv
# The Name Server boot success. serializeType=JSON 看到这个表示已经提供成功
#启动broker
bin/mqbroker -n 172.16.185.55:9876  #-n 指定nameserver地址和端口
#启动出错
Java HotSpot(TM) 64-Bit Server VM warning: INFO:
os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot allocate
memory' (errno=12)
……………………………………………………………………………………

启动错误，是因为内存不够，导致启动失败，原因：RocketMQ的配置默认是生产环境的配置，设置的jvm的内存
大小值比较大，对于学习而言没有必要设置这么大，测试环境的内存往往都不是很大，所以需要调整默认值。

#调整默认的内存大小参数
cd bin/
vim runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx128m -Xmn128m -XX:MetaspaceSize=128m -
XX:MaxMetaspaceSize=128m"
cd bin/
vim runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx128m -Xmn128m"
#从新启动测试
bin/mqbroker -n 172.16.55.185:9876
The broker[itcast, 172.17.0.1:10911] boot success. serializeType=JSON and name
server is 172.16.185.55:9876

下面进行发送消息测试：

export NAMESRV_ADDR=127.0.0.1:9876
cd bin
sh tools.sh org.apache.rocketmq.example.quickstart.Producer
#测试结果
SendResult [sendStatus=SEND_OK, msgId=AC110001473C7D4991AD336AEA5703E0,

[topic=TopicTest, brokerName=itcast, queueId=1], queueOffset=1323]
SendResult [sendStatus=SEND_OK, msgId=AC110001473C7D4991AD336AEA6103E3,

[topic=TopicTest, brokerName=itcast, queueId=2], queueOffset=1323]
#可以正常发送消息

测试接收消息：

sh tools.sh org.apache.rocketmq.example.quickstart.Consumer
#测试结果

transactionId='null'}]]
ConsumeMessageThread_6 Receive New Messages: [MessageExt [queueId=2, storeSize=180,

transactionId='null'}]]
#从结果中，可以看出，接收消息正常

3、编写Java代码进行测试

第一步，创建zxl-rocketmq工程
第二步，导入依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>cn.zxl.rocketmq</groupId>
  <artifactId>zxl-rocketmq</artifactId>
  <version>1.0-SNAPSHOT</version>
  <dependencies>
    <dependency>
      <groupId>org.apache.rocketmq</groupId>
      <artifactId>rocketmq-client</artifactId>
      <version>4.3.2</version>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <!-- java编译插件 -->
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
          <encoding>UTF-8</encoding>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

第三步，编写代码

package cn.zxl.rocketmq;
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;
import org.apache.rocketmq.remoting.common.RemotingHelper;
public class SyncProducer {
  public static void main(String[] args) throws Exception {
    //Instantiate with a producer group name.
    DefaultMQProducer producer = new
      DefaultMQProducer("test-group");
    // Specify name server addresses.
    producer.setNamesrvAddr("172.16.55.185:9876");
    //Launch the instance.
    producer.start();
    for (int i = 0; i < 100; i++) {
      //Create a message instance, specifying topic, tag and message body.
      Message msg = new Message("TopicTest11" /* Topic */,
        "TagA" /* Tag */,
       ("Hello RocketMQ " +i).getBytes(RemotingHelper.DEFAULT_CHARSET) /* Message body */
     );
      //Call send message to deliver message to one of brokers.
      SendResult sendResult = producer.send(msg);
      System.out.printf("%s%n", sendResult);
   }
    //Shut down once the producer instance is not longer in use.
    producer.shutdown();
 }
}

测试：

Exception in thread "main"
org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException:
sendDefaultImpl call timeout
at
org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(Defaul
tMQProducerImpl.java:612)
at
org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducer
Impl.java:1253)
at
org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducer
Impl.java:1203)
at
org.apache.rocketmq.client.producer.DefaultMQProducer.send(DefaultMQProducer.java:214
)
at cn.zxl.rocketmq.SyncProducer.main(SyncProducer.java:26)

测试结果会发现，发送消息会报错。
原因是什么呢？
仔细观察broker启动的信息：

The broker[itcast, 172.17.0.1:10911] boot success. serializeType=JSON and name server
is 172.16.185.55:9876

会发现，broker的ip地址是172.17.0.1，那么在开发机上是不可能访问到的。
所以，需要指定broker的ip地址。

#创建broker配置文件
vim /haoke/rmq/rmqbroker/conf/broker.conf
brokerIP1=172.16.55.185
namesrvAddr=172.16.55.185:9876
brokerName=broker_haoke_im
#启动broker，通过 -c 指定配置文件
bin/mqbroker -c /haoke/rmq/rmqbroker/conf/broker.conf
The broker[itcast, 172.16.55.185:10911] boot success. serializeType=JSON and name
server is 172.16.55.185:9876  #这样就可以进行访问了
