RocketMQ 集群监控以及Hello World

RocketMQ 目前有两个版本  alibaba版本和apache版本

一、alibaba版本

tomcat部署：

　　apache-tomcat-7.0.90.tar.gz

　　jdk7

　　虚拟机redhat6.5：192.168.1.201

1、上传rocketmq-console.war包到tomcat下webapps

#新建目录
mkdir rocketmq-console
#解压war文件
unzip rocketmq-console.war -d rocketmq-console
#删除war
rm -f rocketmq-console.war

2、修改配置  指定nameserveraddr

cd /usr/local/tomcat7/webapps/rocketmq-console/WEB-INF/classes

vim config.properties

rocketmq.namesrv.addr=192.168.1.201:;192.168.1.202:
throwDone=true

3、启动tomcat

[root@ bin]# /usr/local/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat7
Using CATALINA_HOME:   /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME:        /usr/local/java/jdk1..0_80
Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat started.
[root@ bin]# jps
 Jps
 NamesrvStartup
 Bootstrap
 BrokerStartup

4、浏览器访问

二、apache版本

贡献给apache之后，上面的那个工具就无法使用了，不过今天从网上找到了个新的管理界面。

github地址：https://github.com/apache/incubator-rocketmq-externals

2018年1月23日，更新最新github地址为：https://github.com/apache/rocketmq-externals

参照帮助文件使用即可：

帮助文档路径：https://github.com/apache/incubator-rocketmq-externals/blob/master/rocketmq-console/README.md

具体如下：

1、修改配置文件，使管理界面与rocketmq集群产生关联。

incubator-rocketmq-externals-master/rocketmq-console/src/main/resources/application.properties

修改内容及修改结果如下图所示：

2、编译rocketmq-console

编译命令：mvn clean package -Dmaven.test.skip=true（注意：不要直接使用mvn package，会提示很多错误）

3、将编译好的jar包上传到linux服务器

（如果直接在Linux环境上编译，可以省略这步）

我这里上传到了本地虚拟机192.168.6.5上。路径为：/home/hadmin/jar

4、运行jar包

命令：java -jar target/rocketmq-console-ng-1.0.0.jar

5、使用浏览器访问管理界面

方位地址：http://192.168.6.5:8080/

6、可能遇到的问题

画面可以正常启动，不过从控制台的监控日志上看，存在如下的错误日志。

org.apache.rocketmq.remoting.exception.RemotingTimeoutException: wait response on the channel <192.168.1.80:10918> timeout, 5000(ms)

原因是isVIPChannel默认为true，会监控rocketmq的vip通道，将该属性设置为false即可。

设置后的配置文件如下所示：

server.contextPath=
server.port=8080
#spring.application.index=true
spring.application.name=rocketmq-console
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
logging.config=classpath:logback.xml
#if this value is empty,use env value rocketmq.config.namesrvAddr  NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
rocketmq.config.namesrvAddr=192.168.1.80:9876;192.168.1.81:9876
#if you use rocketmq version < 3.5.8, rocketmq.config.isVIPChannel should be false.default true
rocketmq.config.isVIPChannel=false
#rocketmq-console's data path:dashboard/monitor
rocketmq.config.dataPath=/home/hadmin/data/rocketmq
#set it false if you don't want use dashboard.default true
rocketmq.config.enableDashBoardCollect=true
