rocketmq集群搭建

1、下载rocketmq包

2、解压zip包

3、编译部署

4、配置环境变量

5、启动 NameServer（每台机器都要启动）

6、启动broker（每台机器都要）

7、测试验证

1、下载rocketmq包

　　下载地址：http://rocketmq.apache.org/dowloading/releases/

　　我用的版本是 rocketmq-all-4.2.0-source-release.zip

2、解压zip包

[root@iZbp1hsztk393u9v8k87m3Z local]# unzip rocketmq-all-4.2.0-source-release.zip

3、编译部署

　　前提是已经安装好maven

　　进入到解压出来的目录 rocketmq-all-4.2.0，执行 mvn -Prelease-all -DskipTests clean install -U

　　

　　需要等待几分钟，完成显示

　　

4、配置环境变量

　　vi /etc/profile中添加

#set rocketmq
export rocketmq=/usr/local/rocketmq-all-4.2.0/distribution/target/apache-rocketmq
export PATH=$PATH:$rocketmq/bin

　　添加后别忘了执行source /etc/profile，使环境变量生效

5、启动 NameServer（每台机器都要启动）

　　进入到  /usr/local/rocketmq-all-4.2.0/distribution/target/apache-rocketmq 目录

　　先在/usr/local/rocketmq-all-4.2.0目录下新建文件夹rocketmqlogs

　　启动nameserver

nohup mqnamesrv > /usr/local/rocketmq-all-4.2.0/rocketmqlogs/namesrv.log 2>&1 &

　　启动后查看日志文件是否正确启动，出现红框中的说明已经启动

　　

　　也可以使用jps命令查看

　　

6、启动broker（每台机器都要）

　　6.1 进入到目录：/usr/local/rocketmq-all-4.2.0/distribution/target/apache-rocketmq/conf/2m-noslave

　　　　配置 broker-a.properties文件

　　　　在最后一行添加 namesrvAddr=10.132.131.64:9876;10.132.131.81:9876;10.132.131.82:9876

　　　　因为64/81/82三台机器都要安装rocketmq,做集群，同理配置，81机器的broker-b.properties文件，82机器的broker-c.properties文件

[root@iZbp1hsztk393u9v8k87mcZ 2m-noslave]# vi broker-a.properties

brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
namesrvAddr=10.132.131.64:9876;10.132.131.81:9876;10.132.131.82:9876

 　　启动broker

nohup mqbroker -c /usr/local/rocketmq-all-4.2.0/distribution/target/apache-rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &

　　jps查看下，已经启动

　　

7、测试验证

　　7.1 命令行验证

　　最后使用clusterList命令来验证一下集群健康状态
　　命令：

mqadmin clusterList -n 10.132.131.64:9876

　　执行结果如下：

　　

　　三台机器都已经成功启动

 　　7.2 rocketmq-console页面验证

　　　　这个更直观，搜一下很简单

　　　　参考：https://blog.csdn.net/so_geili/article/details/90142461

8、停止服务

　　停止时需要先停止broker，再停止namesrv

　　mqshutdown broker

　　mqshutdown namesrv
