我試圖使用jconsole作爲一個JMX客戶端通過ssh連接到遠程Java應用JConsole連接到遠程JVM通過SSH

我已經建立了CustomAgent上https://blogs.oracle.com/jmxetc/entry/connecting_through_firewall_using_jmx

描述的代碼代理在這裏

/**

    public static void premain(String agentArgs) 
    throws IOException {

     // 
     System.out.println("Create an RMI connector server"); 
     final String hostname = InetAddress.getLocalHost().getHostName(); 
     //JMXServiceURL url =

     JMXConnectorServer cs =

構建腳本是在這裏

    <property name="src.dir"  value="src"/> 
    <property name="build.dir" value="build"/> 
    <property name="classes.dir" value="${build.dir}/classes"/>

開始使用在遠程機器上的應用程序

的java -javaagent:試劑/建造/罐/ agent.jar中 -Dexample.rmi.agent.port = 6004 -server -server -Dcom.sun.management .jmxremote.authenticate =「false」-Dcom.sun.management.jmxremote =「true」-Dcom.sun.management.jmxremote.ssl =「false」-Dcom.sun.management.jmxremote.local.only =「false」 -jar路徑到我的應用程序內/ app.jar

兩個端口的主機,6004和6005,我可以通過JConsole的連接應用程序。如果JConsole的是本地的應用程序開放。

我再創建2條SSH隧道

SSH隧道SSH-L 6004:本地主機:6004 FOO @服務器SSH隧道 的ssh -L 6005:本地主機:6005 FOO @服務器

的隧道已成功創建。我可以在這些端口上遠程登錄。

現在的問題是,我不能使用JConsole雖然

服務遠程連接:JMX:RMI://本地主機:6005/JNDI/RMI://本地主機:6004/jmxrmi

JConsole的-J-Djava.util.logging.config.file = logging.properties -debug

JConsole的是由啓動

我需要添加

-Djava.rmi.server.hostname =本地主機

到-server參數現在熱點7 JVM直接支持

+0

是的,萬一你有多個網絡適配器。您需要使用上述屬性指定要偵聽遠程連接的適配器的IP地址。 –

0

嘗試運行您的服務器有以下選項:

-Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=6004 
-Dcom.sun.management.jmxremote.rmi.port=6004 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.local.only=true 

一旦你有一個6004的隧道試試這個與jcon鞋底:

jconsole -J-DsocksProxyHost=127.0.0.1 -J-DsocksProxyPort=6004 service:jmx:rmi:///jndi/rmi://0.0.0.0:6004/jmxrmi -J-DsocksNonProxyHosts=
