RocketMQ的安装（单节点）

接下来，我们从无到有，搭建一个RocketMQ的环境吧，单节点走起。

安装虚拟机（optional）

假如你没有云主机也没搭建本地虚拟机，那么推荐使用VMware Workstation Player 来搭建自己的虚机，Virtual Box 也不错，这两款体积都比较小，适合个人开发。

VMware Workstation 15.5 Player的安装，请移步： VMware-使用 VMware Workstation 15.5 Player 替换 VMware Workstation Pro

安装的时候，把网络提前启用，省去了后面的配置

JDK 和 RocketMQ

RocketMQ 是个纯java、分布式、队列模型的开源消息中间件，所以JDK必不可少了。

RocketMQ 版本及JDK的对应关系

RocketMQ 版本及JDK的对应关系：戳这里

版本选择

JDK版-1.8.0_221
RocketMQ版本：4.3.2 release

下载Binary 二进制版本的即可，安装方便。

JDK1.8.0_221 安装

JDK（rpm）安装：戳这里【rpm安装后，默认安装路径为/usr/java】

JDK (tar.gz) 安装：戳这里

RocketMQ- 安装、配置、启动、关闭

RocketMQ- 安装

解压zip包到指定目录

约定下安装目录： /usr/local/rocketmq ，没有的目录自行创建。

将下载好的 rocketmq-all-4.3.2-bin-release.zip 使用unzip命令，解压到 /usr/local/rocketmq目录下如下所示

[root@artisan rocketmq]# pwd
/usr/local/rocketmq
[root@artisan rocketmq]# ll
total 0
drwxr-xr-x. 6 root root 96 Nov  3 19:10 rocketmq-all-4.3.2-bin-release

环境变量设置

修改 /etc/profile ，检查jdk与rocketmq的环境变量是否配置（这里配置的是全局变量，对所有用户生效，可以不在这里配置，在应用的脚本里设置也是可以的，这里为了方便后续的操作，添加到全局变量中）

在/etc/profile 末尾增加如下内容（根据自己下载的软件信息和安装目录配置）

# JDK
export JAVA_HOME=/usr/java/jdk1.8.0_221-amd64
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
#rocketmq
export ROCKETMQ_HOME=/usr/local/rocketmq/rocketmq-all-4.3.2-bin-release
export PATH=$ROCKETMQ_HOME/bin:$PATH

第二步：刷新环境变量

source /etc/profile

看下是否生效了

[root@artisan ~]# echo $JAVA_HOME
/usr/java/jdk1.8.0_221-amd6
[root@artisan ~]# echo $ROCKETMQ_HOME
/usr/local/rocketmq/rocketmq-all-4.3.2-bin-release
[root@artisan ~]#

OK，生效，与配置相同。

RocketMQ-配置

修改配置文件 broker.conf

位于$ROCKETMQ_HOME/conf目录下，启动的时候可以通过-c参数加载该配置文件

#集群名称，可自定义
brokerClusterName=DefaultCluster
brokerName=broker‐a
brokerId=0
#rocketmq‐name服务地址,多个地址用;分开，不配置默认为localhost:9876
namesrvAddr=192.168.18.130:9876
deleteWhen=04
fileReservedTime=48
#主从角色SYNC_MASTER,ASYNC_MASTER,SLAV
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
##允许自动创建主题topi
autoCreateTopicEnable=true
#broker监听端口
listenPort=10911
#消息存储根路径
storePathRootDir=/data/rocketmq/store
#日志路径
storePathCommitLog=/data/rocketmq/store/commitlog

配置说明：

1.namesrvAddr ： NameServer地址，可以配置多个，用逗号分隔；

2.brokerClusterName 所属集群名称，如果节点较多可以配置多个

3.brokerName broker名称，master和slave使用相同的名称，表明他们的主从关系4.brokerId 0表示Master，大于0表示不同的slave

5.deleteWhen 表示几点做消息删除动作，默认是凌晨4点

6.fileReservedTime 在磁盘上保留消息的时长，单位是小

7.brokerRole 有三个值：【SYNC_MASTER，ASYNC_MASTER，SLAVE】；同步和异步表示Master和Slave之间同步数据的机制；

8.flushDiskTyp 刷盘策略，取值为：【ASYNC_FLUSH，SYNC_FLUSH】表示同步刷盘和异步刷盘；SYNC_FLUSH消息写入磁盘后才返回成功状态，ASYNC_FLUSH不需要；

9.listenPort 启动监听的端口号

10.storePathRootDir 存储消息的根目录

11.storePathCommitLog 默认路径${user.home} \store\${commitlog}\${fileName}

jvm 内存设置（optional）

RocketMQ 默认给的jvm配置是很大的，我这里使用了虚拟机，分配的内存只有1G，所以需要将内存设置的小一些，否则无法启动。

修改$ROCKETMQ_HOME/bin/runserver.sh 和$ROCKETMQ_HOME/bin/runbroker.sh中JAVA_OPT关于内存的设置

runserver.sh

RocketMQ-启动broker

先启动namesrv ，然后启动broker

不指定启动配置文件

在$ROCKETMQ_HOME/bin下执行

[root@artisan bin]#nohup sh ./mqbroker ‐n 192.168.18.130:9876 autoCreateTopicEnable=true&

指定启动配置配置文件

-c 参数加载配置文件

在$ROCKETMQ_HOME/bin下执行 nohup ./mqbroker -n 192.168.18.130:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &

192.168.18.130:9876为nameserver，broker要注册到该namesrv 注册中心

autoCreateTopicEnable=true(允许创建topic），如果broker.conf配置了autoCreateTopicEnable=true，启动命令中可以省略

关闭防火墙

自己搭建的测试环境，防火墙关闭即可。生产环境考虑通过开放端口访问限制

如果客户端访出现 RemotingTooMuchRequestException: sendDefaultImpl call timeout

在客户端运行Producer时，可能会出现如上异常，这是因为从 Windows 上开发连接

虚拟机中的 nameServer 时要经过 Linux 系统的防火墙，而防火墙一般都会有超时的机制，在网络连接长时间不传输数据时，会关闭这个 TCP 的会话，关闭后再读写，就有可能导致这个异常。

centos7命令如下：

[root@artisan ~]# 关闭防火
[root@artisan ~]# systemctl stop firewalld.service
[root@artisan ~]# 禁止开机启
[root@artisan ~]# systemctl disable firewalld.service

关于autoCreateTopicEnable参数

autoCreateTopicEnable=true,是不是需要在启动的时候开启这个功能，一般情况都是设计阶段定好系统有几个queue，系统上线前，由运维来创建。我们这里测试用，为了防止报错，故设置为true ,自动创建Topic

遇到的问题

1. Vmware Player 虚拟机启动 PXE-E53：No boot filename received \ Operating System not found

ANSWER：

检查虚拟机的设置， 勾选启动时连接

刚用VMware Workstation 15.5 Player 替换了VMware Workstation Pro ，结果Player 没勾选这个选项，所以从磁盘加载ISO的时候找不到。。。
