- 对于 RockatMQ 的理论知识，可以参考《RocketMQ 分布式消息中间件 理论介绍 》、《RocketMQ 集群部署模式 理论介绍 》
- 工欲善其事，必先利其器。既然 RocketMQ 这么深受喜爱，那么本文就讲解如何安装使用 RocketMQ
- Apache 上开源官方地址：https://rocketmq.apache.org/
- GitHub 托管地址：https://github.com/apache/rocketmq
- 阿里官方的介绍文档：http://jm.taobao.org/2017/01/12/rocketmq-quick-start-in-10-minutes/
- Apache 官方提供的 4.3.0 版本的 “快速入门” 文档：https://rocketmq.apache.org/docs/quick-start/
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
- Git 工具用于直接从 GitHub 获取 RocketMQ 项目源码下载到 Linux 系统上
- 然后 Maven 将 RocketMQ 源码进行编译成二进制文件
- 安装了 Java JDK 就可以运行 RocketMQ 了
The following softwares are assumed installed:
- 64bit OS, Linux/Unix/Mac is recommended;
- 64bit JDK 1.8+;
- Maven 3.2.x
- 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.* 》

RocketMQ 下载
下面提供两种下载方式，即可以从 Apache 官网下载，也可以从 gitHub 上进行下载。
从 Apache 下载
- Apache 官方下载网址：https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.3.0/rocketmq-all-4.3.0-source-release.zip
- 这里选择直接下载整个 RocketMQ 项目的源码（带source的，而不是二进制文件[带Binary的]）
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
-

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-rocketm
q (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

- 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
-

-
[

# 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

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:
- 编程方式，如：
producer.setNamesrvAddr("ip:port") - Java 选项，如
：rocketmq.namesrv.addr - 环境变量，如：
NAMESRV_ADDR - 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
-
[

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
