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

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

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

#  limitations under the License.

#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 


[root@artisan ~]# 查看状

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

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。。。
