我使用 JMeter 设置了一个分布式负载测试环境。我正在使用Windows 8.1 中的 Secured Shell使用三台 Linux 机器(RedHat)(IP: xxx.xxx.xxx.121, xxx.xxx.xxx.122, )。xxx.xxx.xxx.123
我已经满足了执行分布式测试的先决条件：
- 所有机器（客户端和从机）都在同一个子网中。
- 所有机器都禁用防火墙。
- JMeter(2.13) 和 JDK 版本(1.6.0_25) 都是一样的。
Client(Master) Machine :xxx.xxx.xxx.123
Server(Slave) Machines: xxx.xxx.xxx.122,xxx.xxx.xxx.121
我做了以下事情：
1)在客户端（主）jmeter.properties文件中添加以下内容：
remote_hosts= xxx.xxx.xxx.122,xxx.xxx.xxx.121
2）向服务器（在每个从机中）添加以下内容jmeter-server：
RMI_HOST_DEF=-Djava.rmi.server.hostname=xxx.xxx.xxx.123（客户端机器 IP）
3）然后使用此命令从那两台从机（xxx.xxx.xxx.122,xxx.xxx.xxx.121 ）启动jmeter-server
./jmeter-server
并获得以下输出。这意味着从机已启动。
xxx.xxx.xxx.121 的输出：
Created remote object: UnicastServerRef [liveRef: [endpoint:[xxx.xxx.xxx.123:41864](local),objID:[1707296d:154c281318b:-7fff, -8101068266055605468]]]
xxx.xxx.xxx.122 的输出：
Using local port: 4000
Created remote object: UnicastServerRef [liveRef: [endpoint:[xxx.xxx.xxx.123:4000](local),objID:[-2a2acf13:154c285ffa2:-7fff, 2939294752655639469]]]
现在我从客户端机器（xxx.xxx.xxx.123）运行以下命令来启动远程测试。
./jmeter -n -t RemoteTest.jmx -r
它为我提供了以下输出：
Creating summariser <summary>
Created the tree successfully using RemoteTest.jmx

那么克服这个异常的确切解决方案是什么。 在过去的两天里，我一直在探索StackOverflow和Stack Exchange以解决类似的问题，并且已经尝试了几乎所有可能的解决方案，但仍然无法摆脱这个异常。实际上，我失败了！！！！所以请在你的答案中具体和详细。
