环境说明

  • 对于 RocketMQ 4.3.0版本，官方要求环境如下，其中 Git 用于从 GitHub 获取源码，没有安装也没关系，可以直接下载
  • 官方推荐的流程是：Linux 系统上安装 Git 工具 、Maven、Java JDK
  1. Git 工具用于直接从 GitHub 获取 RocketMQ 项目源码下载到 Linux 系统上
  2. 然后 Maven 将 RocketMQ 源码进行编译成二进制文件
  3. 安装了 Java JDK 就可以运行 RocketMQ 了

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 （可不使用）
  • 实际操作的 Linux 系统的是 CentOS 7.2.1511 版本，没有实际Linux系统的可以参考《VMware 安装 CentOS 7.* 》
[root@localhost ~]# lsb_release -a

RocketMQ 下载

从 Apache 下载

从 GitHub 下载

  • GitHub 官方下载网址：https://github.com/apache/rocketmq
  • 因为项目是开源的，所以GitHub也有托管整个项目的源码，无论哪种方式下载下来都是一样的。
  • 上面 “环境说明” 中 Git 工具功能之一就是下载 GitHub 上的项目源码。但是如图所示，也可以直接下载即可。

RocketMQ 安装

  • 上面下载的是整个 RocketMQ 项目的源码，可以自己学习或者定制开发，但是要想使用显然这样是不行的

文件上传

  • 因为没有从 Linux 上直接使用 Git 将 RocketMQ 项目源码下载到 Linux 系统上，而是下载到了 Windons 系统上，所以第一步是将项目先上传到 Linux 系统上

项目解压

  • 官方推荐解压命令：  > unzip rocketmq-all-4.3.0-source-release.zip
  • 当然应该也是可以使用其它解压命令的，如 tar 等，这里还是和官方保持一致。当没有安装 unzip 命令包时是使用不了，此时应该先安装 unzip 命令包
  • 使用如下的 “ yum list unzip”  可以查看 unzip 包的安装情况
[root@localhost local]# yum list unzip

编译部署

  • 使用 Maven 来编译整个项目，官方推荐命令
  > unzip rocketmq-all-4.3.0-source-release.zip        (解压)
  > cd rocketmq-all-4.3.0/                             (进入解压目录)
  > mvn -Prelease-all -DskipTests clean install -U     (编译部署)
  > cd distribution/target/apache-rocketmq             (进入指定目录)
  • 进入到上面解压后的目录 “rocketmq-all-4.3.-0” 下，指令命令 “mvn -Prelease-all -DskipTests clean install -U”
  • 接着就会从 Maven 中央仓库下载项目依赖的 jar 包编译部署，这可能需要几分钟的时间，如下所示从 阿里云 中央仓库进行下载

  • 如下所示 5 分钟之后项目构建成功

RocketMQ 操作

启动 NameServer

  • 先进入 RocketMQ 安装目录下的  distribution/target/apache-rocketmq 目录
  • 启动的时候先启动 namesrv，然后启动 broker
  • 官方指导命令：
# 启动命令,并且常驻内存
$ nohup sh bin/mqnamesrv &
# 查看启动日志能看到：The Name Server boot success字样则成功
$ tail -f ~/logs/rocketmqlogs/namesrv.log

nohup sh mqnamesrv & ：属于后台启动

sh mqnamesrv ：属于终端启动，直接输出日志信息，按 ctrl+c 可直接关闭退出

  • 如下所示，看到 “ The Name Server boot success. serializeType=JSON  ” 表示启动成功
[root@localhost apache-rocketmq]# pwd
/usr/local/rocketmq-all-4.3.0/distribution/target/apache-rocketmq
[root@localhost apache-rocketmq]# nohup sh bin/mqnamesrv &
[1] 5865
[root@localhost apache-rocketmq]# nohup: 忽略输入并把输出追加到"nohup.out"
tail -f ~/logs/rocketmqlogs/namesrv.log
2018-08-10 01:29:12 INFO main - tls.client.keyPath = null
2018-08-10 01:29:12 INFO main - tls.client.keyPassword = null
2018-08-10 01:29:12 INFO main - tls.client.certPath = null
2018-08-10 01:29:12 INFO main - tls.client.authServer = false
2018-08-10 01:29:12 INFO main - tls.client.trustCertPath = null
2018-08-10 01:29:13 INFO main - Using OpenSSL provider
2018-08-10 01:29:14 INFO main - SSLContext created for server

2018-08-10 01:29:14 INFO FileWatchService - FileWatchService service started
  • 在当前目录下会有一个 nohup.out 的日志文件，可以打开查看 namesrv 的启动情况

启动 Broker

  • 同样进入 RocketMQ 安装目录下的  distribution/target/apache-rocketmq 目录
  • 官方指导命令：
# 启动命令，并且常驻内存:注意ip地址要配置成为服务的ip地址，保证地址以及端口能够访问
> nohup sh bin/mqbroker -n localhost:9876 &

# 查看启动日志
> tail -f ~/logs/rocketmqlogs/broker.log

nohup sh bin/mqbroker -n localhost:9876 & ：属于后台启动

sh bin/mqbroker -n localhost:9876 ：属于终端启动，直接输出日志信息，按 ctrl+c 可直接关闭退出

  • 如下图所示，启动之后同样提示将日志信息追加到了当前目录下的 nohup.out 文件中
  • 输入 tail -f ~/logs/rocketmqlogs/broker.log 查看日志，如果看到 "The broker[%s, 172.30.30.233:10911] boot success..." ,则表示启动成功
[root@localhost apache-rocketmq]# nohup sh bin/mqbroker -n localhost:9876 &
[1] 7202
[root@localhost apache-rocketmq]# nohup: 忽略输入并把输出追加到"nohup.out"
  • 如果 tail -f ~/logs/rocketmqlogs/broker.log 提示找不到文件，则打开 当前目录(apache-rocketmq)下的 nohup.out 日志文件查看，发现启动 Broker 失败：无法分配内存
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.
# An error report file with more information is saved as:

内存分配失败解决办法

  • 这是因为 apache-rocketmq/bin 目录下启动 nameserv 与 broker 的 runbroker.sh 和 runserver.sh 文件中默认分配的内存太大，而系统实际内存却太小导致启动失败
  • 通常像虚拟机上安装的 CentOS 服务器内存可能是没有高的，只能调小。实际中应该根据服务器内存情况，配置一个合适的值
  • 找到下面的 runbroker.sh 和 runserver.sh 文件
[root@localhost bin]# pwd 
/usr/local/rocketmq-all-4.3.0/distribution/target/apache-rocketmq/bin

发送消息

  • 发送/接收消息之前，需要告诉客户端(Producer、Consumer)名称服务器的位置，RocketMQ 提供了多种方法来实现这一点:
  1. 编程方式，如：producer.setNamesrvAddr("ip:port")
  2. Java 选项，如：rocketmq.namesrv.addr
  3. 环境变量，如：NAMESRV_ADDR
  4. HTTP 端点
  • 官方指导命令：
 > export NAMESRV_ADDR=localhost:9876
 > sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
 SendResult [sendStatus=SEND_OK, msgId= ...
  • 如下所示官方提供这个例子属于生产者，用于发送消息，运行之后会发送大量的消息，之后就会退出
[root@localhost apache-rocketmq]# export NAMESRV_ADDR=localhost:9876
[root@localhost apache-rocketmq]# sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

接收消息

  • 官方指导命令：
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
 ConsumeMessageThread_%d Receive New Messages: [MessageExt...
  • 上面的消息发送完毕之后就会退出，在同一窗口中可以使用消费者类来进行接收消息，如下所示，显然是多线程的
[root@localhost apache-rocketmq]# sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
ConsumeMessageThread_3 Receive New Messages: [MessageExt [queueId=0, storeSize=180, queueOffset=1031, sysFlag=0, bornTimestamp=1533841514766, bornHost=/192.168.58.129:46816, storeTimestamp=1533841514767, storeHost=/192.168.58.129:10911, msgId=C0A83A8100002A9F00000000000B518A, commitLogOffset=741770, bodyCRC=895437781, reconsumeTimes=0, preparedTransactionOffset=0, toString()=Message{topic='TopicTest', flag=0, properties={MIN_OFFSET=0, MAX_OFFSET=1250, CONSUME_START_TIME=1533841719674, UNIQ_KEY=C0A83A8120207D4991AD2F02D50E007C, WAIT=true, TAGS=TagA}, body=[72, 101, 108, 108, 111, 32, 82, 111, 99, 107, 101, 116, 77, 81, 32, 49, 50, 52], transactionId='null'}]]

...............

关闭服务器

  • 同样都是在 RocketMQ 安装目录下的  distribution/target/apache-rocketmq 目录下执行命令
  • 与启动顺序相反进行关闭，先关闭 broker、在关闭 nameserv
> 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

常用命令

除了上面几个命令之外，还有如下一些较常用的命令，ip请以实际为准：

  • 查看集群情况： ./mqadmin clusterList -n 127.0.0.1:9876
  • 查看 broker 状态： ./mqadmin brokerStatus -n 127.0.0.1:9876 -b 172.20.1.138:10911
  • 查看 topic 列表： ./mqadmin topicList -n 127.0.0.1:9876
  • 查看 topic 状态： ./mqadmin topicStatus -n 127.0.0.1:9876 -t MyTopic (换成想查询的 topic)
  • 查看 topic 路由： ./mqadmin topicRoute -n 127.0.0.1:9876 -t MyTopic
