java - Jmeter远程测试: . RemoteJMeterEngineImpl_Stub(无安全管理器:RMI类加载器禁用)

Question

这个问题已经有答案了:

java.rmi.ServerException: RemoteException occurred in server thread (ClassNotFoundException) (5 个回答)

已关闭 5 年前。

我是 Jmeter 的新手，我尝试使用此工具和下一个配置来运行分布式测试:

1. 客户端(主)- Windows 7
   • Java 版本 - 1.8.0_92(也尝试过 7u79)
   • JMeter，版本 - 2.13
2. 服务器(从属)- VM Ubuntu 14(使用 VirtualBox)
   • Java 版本 - 1.7.0_95
   • Jmeter 版本 - 2.8.20130705

我已经完成并尝试了在官方教程和其他帖子(包括 stackoverflow 帖子)中找到的所有内容，但最终取得了成功。当我尝试通过客户端在服务器上运行测试时，我总是收到下一个错误:

java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: org.apache.jmeter.engine.RemoteJMeterEngineImpl_Stub (no security manager: RMI class loader disabled)

我尝试过不同的组合:

• 在 Ubuntu 和 Windows 上禁用防火墙
• 使用同一子网
• 在 jmeter-server 文件中设置主机名:

  RMI_HOST_DEF=-Djava.rmi.server.hostname=172.29.148.49

• 创建 .java.policy 文件并授予 jmeter/bin 目录中的所有权限:

  grant { permission java.security.AllPermission; };

• jmeter-server 文件中的设置:

  -Djava.security.policy=file:/usr/share/jmeter/bin/.java.policy

• 在 java.policy 文件 (usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/java.policy) 中设置所有权限

结果，当我在 VM Ubuntu 上启动 jmeter-server 时，似乎一切都很好。我得到:

log_file=jmeter-server.log java.io.FileNotFoundException: jmeter-server.log     (Permission denied)
[log_file-> System.out]

任何人都可以帮助解决这个问题吗？

非常感谢。

What I've tried in different combinations:

• disable firewall on Ubuntu and Windows

不相关

• using the same subnet

无关紧要。

• setting hostname in jmeter-server file:

 RMI_HOST_DEF=-Djava.rmi.server.hostname=172.29.148.49

无关紧要。

• creating .java.policy file with granting all permissions in jmeter/bin directory:

grant { permission java.security.AllPermission; };

无关紧要。

• setting in jmeter-server file:

-Djava.security.policy=file:/usr/share/jmeter/bin/.java.policy

无关紧要。

• setting all permissions in java.policy file (usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/java.policy)

无关紧要。

你的做法令人费解。防火墙、子网、主机名、.policy 文件、其名称及其内容都与 ClassNotFoundExceptions 没有任何关系，无论是单独还是任意组合，令人费解的是为什么任何人都可以否则:特别是与安全策略操作相关时，当错误消息明确指出安全管理器未安装时。

解决 ClassNotFoundException 的方法是将相关类部署到相关 JVM。在本例中为客户端。 Jmeter在一些JAR文件中提供了这个类，并且它在客户端的CLASSPATH中是必需的。
