我的架构:代理、防火墙和其他交换机后面的kubernetes名称空间。我的主人把任务发送给奴隶，当脚本结束时，它关闭奴隶和主人。我有网络，入口和出口配置和运行。我在3端口范围内有开放端口，例如60000-60002,1099-1101.

我的问题是:通常，当我开始测试时，主程序应该发送日志，例如：

"Oct 12, 2022 11:31:39 AM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.
Creating summariser <summary>
Created the tree successfully using /mount/10_2022/scenario.jmx
Configuring remote engine: slave-1
Using local port: 60000
Starting distributed test with remote engines: [slave-1] @ October 12, 2022 11:31:41 AM CEST (1665567101036)
Remote engines have been started:[opl-jmeter-distributed-slave-1]
Waiting for possible Shutdown/StopTestNow/HeapDump/ThreadDump message on port 4445"

当主程序发送日志时：

"Oct 12, 2022 11:31:39 AM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.
Creating summariser <summary>
Created the tree successfully using /mount/10_2022/scenario.jmx
Configuring remote engine: slave-1
Using local port: 60000
Starting distributed test with remote engines: [slave-1] @ October 12, 2022 11:31:41 AM CEST (1665567101036)

<在这一行之间大约是7-10分钟break.>

"Remote engines have been started:[opl-jmeter-distributed-slave-1]
Waiting for possible Shutdown/StopTestNow/HeapDump/ThreadDump message on port 4445"

在此之后什么都不会发生，除了日志错误，例如：

"2022-10-12 11:40:30,274 ERROR o.a.j.s.RemoteListenerWrapper: testStarted(host) on slave-1
java.rmi.ConnectException: Connection refused to host: <MASTER'S IP>; nested exception is: java.net.ConnectException: Connection timed out (Connection timed out)"

和

"2022-10-12 11:49:18,668 ERROR o.a.j.s.BatchSampleSender: sampleOccurred
java.rmi.ConnectException: Connection refused to host: <MASTER'S IP>; nested exception is:java.net.ConnectException: Connection timed out (Connection timed out)"

我开始调试我的操作，这就是我从主日志中得到的：

"Oct 13, 2022 10:45:37 AM sun.rmi.transport.tcp.TCPChannel free
FINE: RMI RenewClean-[172.16.28.15:60000,SSLRMIClientSocketFactory(keyStoreLocation=/mount/keyStore/rmi_keystore.jks, type=JKS, trustStoreLocation=/mount/keyStore/rmi_keystore.jks, type=JKS, alias=rmi)]: create reaper

我开始调试我的操作，这就是我从主日志中得到的：

请帮帮忙。有线索吗？为什么我的测试不开始？

哪里出问题了？下面是我在防火墙上打开的端口: 1099-1101 8000-8002 60000-60002

很可能你的RMI配置不正确

您需要创建一个服务并公开以下端口：

1099或其他什么是你的server_port
4000或其他什么是你的server.rmi.localport

与奴隶的Dockerfile类似：

EXPOSE 1099 4000

在k8s服务中

spec:
  clusterIP: None
  ports:
    - port: 1099
      name: server_port
      targetPort: 1099
    - port: 4000
      name: server_rmi_localport
      targetPort: 4000

并在client.rmi.localport主服务器端对JMeter执行同样的操作。
