Linux系统_ActiveMQ_远程连接JMX

二.有密码方式连接

     1.检查 ActiveMQ 所在服务器 hosts 文件的设置:

          1).使用命令:  cat  /etc/hosts

          127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
               ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

          2).将 127.0.0.1 改为 ActiveMQ 所在服务器的 IP

          192.168.242.128   localhost localhost.localdomain localhost4 localhost4.localdomain4
             ::1     localhost localhost.localdomain localhost6 localhost6.localdomain6

    2.在 apache-activemq-5.12.0/conf 目录下修改 activemq.xml 文件

              <managementContext>   
                     <managementContext createConnector="true" connectorPort="11099" />
             </managementContext>

           注：在标签 <managementContext > 中可以添加 connectorHost="ActiveMQ 服务器所在服务器IP"

      3.在apache-activemq-5.12.0/bin 目录的 activemq 文件最后一行加上如下配置:

         ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=11099 "
         ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"
         ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_CONF}/jmx.access"
         ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"

     4.重启 ActiveMQ 服务器

     5.在本地使用 jconsole 远程连接输入:

        192.168.242.128:11099

        admin(用户名)/activemq(密码)

             注:  在 apache-activemq-5.12.0/conf 目录下有两个文件:

                    jmx.access(设置用户权限的文件)

                    jmx.password(设置子用户名和密码的文件)

三.通过 JMX 的编程接口来与 broker 进行交互,观察 broker 的 jmx 中都提供的东西：

import java.util.Iterator;  

import java.util.Set;  

import javax.management.MBeanAttributeInfo;  

import javax.management.MBeanInfo;  

import javax.management.MBeanOperationInfo;  

import javax.management.MBeanServerConnection;  

import javax.management.ObjectInstance;  

import javax.management.ObjectName;  

import javax.management.remote.JMXConnector;  

import javax.management.remote.JMXConnectorFactory;  

import javax.management.remote.JMXServiceURL;  

public class TestJMX {  

    public static void main(String[] args) throws Exception {  

        String surl = "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi";  

        JMXServiceURL url = new JMXServiceURL(surl);  

        JMXConnector jmxc = JMXConnectorFactory.connect(url, null);  

        MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();  

        System.out.println("Domains:---------------");  

        String domains[] = mbsc.getDomains();  

        for (int i = 0; i < domains.length; i++) {  

            System.out.println("\tDomain[" + i + "] = " + domains[i]);  

        }  

        System.out.println("all ObjectName：---------------");  

        Set<ObjectInstance> set = mbsc.queryMBeans(null, null);  

        for (Iterator<ObjectInstance> it = set.iterator(); it.hasNext();) {  

            ObjectInstance oi = (ObjectInstance) it.next();  

            System.out.println("\t" + oi.getObjectName());  

        }  

        System.out.println("org.apache.activemq:BrokerName=localhost,Type=Broker：---------------");  

        ObjectName mbeanName = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Broker");  

        MBeanInfo info = mbsc.getMBeanInfo(mbeanName);  

        System.out.println("Class: " + info.getClassName());  

        if (info.getAttributes().length > 0){  

            for(MBeanAttributeInfo m : info.getAttributes())  

                System.out.println("\t ==> Attriber：" + m.getName());  

        }  

        if (info.getOperations().length > 0){  

            for(MBeanOperationInfo m : info.getOperations())  

                System.out.println("\t ==> Operation：" + m.getName());  

        }     

        jmxc.close();  

    }  

}
