performance - 在同一主机上运行多个 jmeter-server

Question

我想以分布式方式运行 JMeter。我的要求是在我的从机上运行多个 jmeter-server 进程。为此，我运行了以下命令。

./jmeter-server -Djava.rmi.server.hostname=XX.XX.X.XXX -Dserver.rmi.localport=60001

./jmeter-server -Djava.rmi.server.hostname=XX.XX.X.XXX -Dserver.rmi.localport=60001

每次运行此命令时，我都会在控制台上看到以下消息。同样的错误是端口 60002

Created remote object: UnicastServerRef2 [liveRef: [endpoint:[XX.XX.X.XXX:60001](local),objID:[-823e97d:171c37a0bf7:-7fff, -7549432026360676360]]]


Created remote object: UnicastServerRef2 [liveRef: [endpoint:[XX.XX.X.XXX:60002](local),objID:[7b7158d6:171c37bd76f:-7fff, 2942891814894680180]]]

在主服务器上，远程服务器配置为 XX.XX.X.XXX:60001 和 XX.XX.X.XXX:60002。但每次我运行测试时，我都会遇到以下错误。

我已经检查过，端口 1099、60001 和 60002 对所有 TCP 和 UDP 流量都是开放的。

有人可以帮忙吗？

以这种方式运行服务器:

jmeter -Dserver_port=60001 -s -j jmeter-server1.log -Djava.rmi.server.hostname=XX.XX.X.XXX


jmeter -Dserver_port=60002 -s -j jmeter-server1.log -Djava.rmi.server.hostname=XX.XX.X.XXX

然后这样控制:

jmeter -R -Jremote_hosts=XX.XX.X.XXX:60001,XX.XX.X.XXX:60002 -n -t Testplan.jmx -l results.csv -e -o reportfolder
