在生产环境，我们安装的是RocketMQ的集群。但是在开发和测试环境，由于资源的限制，没有这么多的服务器，所以一般安装单机版的就可以满足使用需求。

# 一、整体规划 #

这里安装的RocketMQ为单节点RocketMQ，版本号为4.3.0

# 二、准备工作 #

https://www.oracle.com/technetwork/java/javase/archive-139210.html 下载jdk，这边选择的是jdk-8u144-linux-x64.tar.gz

http://rocketmq.apache.org/dowloading/releases/ 下载RocketMQ，这边选择的版本是rocketmq-all-4.3.1-bin-release.zip

官网给出的环境要求是:  
JDK版本1.8+ （RocketMQ是JAVA写的）

# 三、部署JAVA环境 #

tar -zxvf jdk-8u144-linux-x64.tar.gz -C /usr/local/
    ln -s /usr/local/jdk1.8.0_144 /usr/local/jdk
    sed -i.ori '$a export JAVA_HOME=/usr/local/jdk\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\nexport CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar' /etc/profile
    source /etc/profile
    
    #出现下面结果证明部署成功
    [root@localhost opt]# java -version
    java version "1.8.0_144"
    Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
    Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

# 四、安装RocketMQ #

**1.解压重命名**

unzip rocketmq-all-4.3.0-bin-release.zip -C /usr/local/
    mv /usr/local/rocketmq-all-4.3.0-bin-release /usr/local/apache-rocketmq-4.3.0

## 2.修改配置文件 ##

cd /usr/local/rocketmq-4.3.0/conf/
    
    # 先把broker.conf备份下
    cp broker.conf broker.conf_20190821_bak
    
    # 然后修改broker.conf的内容如下（具体配置的含义在集群部署时已经讲过，详见[RocketMQ集群部署](https://blog.csdn.net/wc1695040842/article/details/89517123)）
    vim broker.conf
    
    brokerClusterName = test1
    brokerName = broker-a
    brokerId = 0
    deleteWhen = 04
    fileReservedTime = 48
    brokerRole = ASYNC_MASTER
    flushDiskType = ASYNC_FLUSH
    autoCreateTopicEnable = true
    brokerIP1=192.168.0.161
    namesrvAddr=192.168.0.161:19876
    defaultTopicQueueNums=4
    autoCreateSubscriptionGroup=true
    listenPort=10911
    mapedFileSizeCommitLog=1073741824
    mapedFileSizeConsumeQueue=300000
    diskMaxUsedSpaceRatio=88
    storePathRootDir=/usr/local/rocketmq-4.3.0/store
    storePathCommitLog=/usr/local/rocketmq-4.3.0/store/commitlog
    storePathConsumeQueue=/usr/local/rocketmq-4.3.0/store/consumequeue
    storePathIndex=/usr/local/rocketmq-4.3.0/store/index
    storeCheckpoint=/usr/local/rocketmq-4.3.0/store/checkpoint
    abortFile=/usr/local/rocketmq-4.3.0/store/abort
    maxMessageSize=65536

**3.修改RocketMQ的NameServer运行端口**  
因为公司不允许用默认的9876端口运行，所以需要修改下运行端口

# 修改端口很简单，在conf目录下新建一个nameser.properties文件，然后写入一行配置即可。
    vim nameser.properties
    
    listenPort=19876

**4.创建日志和存储文件等的存放目录**

mkdir -p /usr/local/rocketmq-4.3.0/logs /usr/local/rocketmq-4.3.0/store /usr/local/rocketmq-4.3.0/store/commitlog /usr/local/rocketmq-4.3.0/store/config /usr/local/rocketmq-4.3.0/store/consumequeue /usr/local/rocketmq-4.3.0/store/index

**5.修改NameServer的启动文件**  
由于默认的NameServer的启动文件的JVM内存给的比较大，由于这里是测试环境，所以这边需要改小点。如果是线上的话，就根据实际情况来。

vim /usr/local/rocketmq-4.3.0/bin/runserver.sh

**6.修改broker的启动文件**  
和上面一样，broker的启动文件的JVM参数也需要调整下。

vim /usr/local/rocketmq-4.3.0/bin/runbroker.sh  
![在这里插入图片描述][20190821111958158.png]

# 五、启动 #

**1.启动NameServer**

nohup sh /usr/local/rocketmq-4.3.0/bin/mqnamesrv -c /usr/local/rocketmq-4.3.0/conf/nameser.properties >> /usr/local/rocketmq-4.3.0/logs/mqnamesrv_stdout.log 2>&1 &

**2.启动broker**

nohup sh /usr/local/rocketmq-4.3.0/bin/mqbroker -c /usr/local/rocketmq-4.3.0/conf/broker.conf >> /usr/local/rocketmq-4.3.0/logs/broker_stdout.log 2>&1 &

全部启动完成之后可以通过jps命令查看进程
