## 下载二进制包 ##

下载链接：[RocketMQ官网][RocketMQ]

![007S8ZIlly1gic4kpuahsj31gw0u0wml.jpg][]

注：二进制包是编译好的，拿来可以直接用，如果不需要定制化，改动源码，可选择二进制包

## 机器准备 ##

准备三台机器，每台机器需要安装好jdk，1.8以上版本；

集群使用交叉部署：三台机器，每台各自装一个nameserver，三个broker：一个master，两个其他master的slave；

目录结构：

机器1：namesever-1、master-a、b-slave1、c-slave1

![format_png][]

机器2：namesever-2、master-b、a-slave1、c-slave2

![format_png 1][]

机器3：namesever-3、master-c、a-slave2、b-slave2

![format_png 2][]

注意：将二进制包解压后的文件，复制到以上12个文件夹中，使用独立的二进制包进行部署，因为需要将各自的日志文件、数据文件单独存储，如果不需要分离，则可使用同一个包

## 部署nameserver ##

创建两个目录：data、logs，用于存放数据和日志，rocketmq471是提前解压好的二进制文件目录：

![format_png 3][]

### 修改配置文件 ###

RocketMQ主目录：/neworiental/rocketmq01/rocketmq-nameserver/rocketmq471

新建nameserver配置文件：/neworiental/rocketmq01/rocketmq-nameserver/rocketmq471/conf/nameserver.conf

修改nameserver.conf文件：

#数据保存目录,需要配置,不配置的话默认在/root/namesrv
    kvConfigPath=/neworiental/rocketmq01/rocketmq-nameserver/data/kvConfig.json
    #是否启用Epoll IO模型
    useEpollNativeSelector=true
    #端口
    listenPort=9876

### 修改日志路径 ###

日志文件路径：/neworiental/rocketmq01/rocketmq-nameserver/rocketmq471/conf/logback\_namesrv.xml

使用命令批量替换：

sed -i ‘s?$\{user.home\}/logs/rocketmqlogs?**/neworiental/rocketmq01/rocketmq-nameserver/logs**?’ logback\_namesrv.xml

打开logback\_namesrv.xml，可以看到路径已全部替换：

![format_png 4][]

### 修改启动脚本 ###

可根据需求修改启动脚本，如：JVM配置、堆栈大小等，路径：

/neworiental/rocketmq01/rocketmq-nameserver/rocketmq471/bin/mqnamesrv

### 启动nameserver ###

nohup sh /neworiental/rocketmq01/rocketmq-nameserver/rocketmq471/bin/mqnamesrv -c /neworiental/rocketmq01/rocketmq-nameserver/rocketmq471/conf/nameserver.conf >/dev/null 2>&1 &

根据以上步骤启动剩下两个nameserver，配置文件直接复制使用

## 部署broker ##

以master-a节点为示例

### 修改日志路径 ###

日志配置文件路径：

/neworiental/rocketmq01/**rocketmq-a**/rocketmq471/conf/logback\_broker.xml

/neworiental/rocketmq01/**rocketmq-a**/rocketmq471/conf/logback\_namesrv.xml

/neworiental/rocketmq01/**rocketmq-a**/rocketmq471/conf/logback\_tools.xml

执行命令：（注意不同的Broker目录不一样）

sed -i 's?${user.home}/logs/rocketmqlogs?/neworiental/rocketmq01/rocketmq-a/logs?' logback_broker.xml
    sed -i 's?${user.home}/logs/rocketmqlogs?/neworiental/rocketmq01/rocketmq-a/logs?' logback_namesrv.xml
    sed -i 's?${user.home}/logs/rocketmqlogs?/neworiental/rocketmq01/rocketmq-a/logs?' logback_tools.xml

### 修改配置文件 ###

配置文件路径：

RoketMQ的端口配置需要注意，详情见：[集群端口配置讲解][Link 1]

#端口（注意：broker启动后，会占用3个端口，分别在listenPort基础上-2，+1，供内部程序使用，所以集群一定要规划好端口，避免冲突）
    listenPort = 10911
    #slave连接端口,配置之后无效，所以不用配
    #haListenPort = 20911
    #RocketMQ主目录
    rocketmqHome = /neworiental/rocketmq01/rocketmq-a/rocketmq471
    #集群名称
    brokerClusterName = Rocketmq01
    #nameserver地址，多个以分号隔开
    namesrvAddr=172.22.36.68:9876;172.22.36.69:9876;172.22.36.70:9876
    #broker名称（每组主从节点使用相同的brokerName，方便查看）
    brokerName = broker-a
    #Broker对外提供服务地址
    brokerIP1 = 172.22.36.68
    #供slave同步消息的地址
    brokerIP2= 172.22.36.68
    #broker的id,0为主,正数0为从
    brokerId = 0
    #数据存放的根目录
    storePathRootDir = /neworiental/rocketmq01/rocketmq-a/store
    #commit log保存目录
    storePathCommitLog = /neworiental/rocketmq01/rocketmq-a/store/commitlog
    #消费队列存储路径存储路径
    storePathConsumerQueue = /neworiental/rocketmq01/rocketmq-a/store/consumequeue
    #删除文件时间点，默认凌晨4点。24小时制，单位小时
    deleteWhen = 04
    #文件保存小时数
    fileReservedTime = 168
    #SYNC_MASTER/ASYNC_MASTER/SLAVE 节点角色
    brokerRole = ASYNC_MASTER
    #刷盘方式
    flushDiskType = ASYNC_FLUSH
    #是否允许Broker自动创建Topic
    autoCreateTopicEnable = false
    #是否允许 Broker 自动创建订阅组
    autoCreateSubscriptionGroup = false
    #linux开启epoll
    useEpollNativeSelector = true

### 修改启动脚本 ###

文件路径：/neworiental/rocketmq01/**rocketmq-a**/rocketmq471/bin/runbroker.sh

可根据需求，修改jvm参数、GC日志目录等：

![007S8ZIlly1gicc012xkcj310m0o8jxw.jpg][]

### 启动Broker ###

nohup sh /neworiental/rocketmq01/rocketmq-a/rocketmq471/bin/mqbroker -c /neworiental/rocketmq01/rocketmq-a/rocketmq471/conf/broker.conf >/dev/null 2>&1 &

根据以上步骤，部署其余8个broker。

**友情提示：对于这种中间件集群的搭建，基本就是不同的节点，要设置不同的存储目录，不同的配置文件，由于节点比较多，操作比较繁琐，很容易出现失误，所以可以先搭建好一个节点，确保可行之后，在本地模拟线上每个机器、每个节点的目录结构，把所有的节点对应的配置文件先改好了、检查好了，最后再每个节点逐个上传、启动，一定会事半功倍！**

![format_png 5][]

部署完成之后，可以进入任意broker的RocketMQ二进制包的bin目录，用命令查看集群信息：

**sh mqadmin clusterList -n 127.0.0.1:9876**

![format_png 6][]

可以看到3主3从的RocketMQ集群搭建成功！

## 部署Console ##

RocketMQ-Console是RocketMQ的控制台页面，方便查看集群的具体信息和使用情况

### 下载源码 ###

地址：https://github.com/apache/rocketmq-externals.git

下载后，使用IDEA打开**rocketmq-console**子模块

### 修改配置文件 ###

![format_png 7][]

### 修改日志路径 ###

![format_png 8][]

检查pom.xml，修改RocketMQ版本：

![format_png 9][]

### 设置用户 ###

需在application.properties中开启用户登录 rocketmq.config.loginRequired=true：（如果不需要设置用户登录，可忽略）

**users.properties文件需要拷贝一份到console的data目录，方便修改，热加载**：/neworiental/rocketmq01/rocketmq-console/data

![format_png 10][]

### 打包部署 ###

使用maven命令或IDEA将console打包，生成jar文件：rocketmq-console-ng-2.0.0.jar

上传到服务器后，java -jar rocketmq-console-ng-2.0.0.jar 启动服务即可  
![d67246e8b8640a22a82ca922b41a0264.png][]

## 部署Exporter ##

需下载源码，自己打包：[https://github.com/apache/rocketmq-exporter][https_github.com_apache_rocketmq-exporter]

*exporter部署一个就可以*

下载后，修改几个地方

nameserver地址：  
![a7c4ecc64c393700bda188aa456bf40e.png][]

日志目录：

![b59cab78322965f1cabc45ba779f5f23.png][]

pom.xml 修改rocketmq版本

![e1441f4b9e0dea8a9b1e8e8b485f62b3.png][]

这段注释掉：

第一次搭建，端口号分配不是很合理，应该每一组主从使用相同的端口号。下面是第二次搭建分配的情况，强迫症看着舒服多了：  
**Broker**

 <thead>

   <th>机器</th> 
   <th>端口</th>

后续的话，还可以加入Systemd管理，注意Systemd需要对每个broker单独配置。
