Question

我想以分布式方式运行JMeter。我的要求是，在我的从属计算机上应该运行多个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

每次我运行此命令时，都会在控制台上看到以下消息。端口60002出现相同的错误

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，将远程服务器配置为XX.XX.X.XXX:60001和XX.XX.X.XXX:60002。但是每次运行测试时，我都会得到以下错误。

我已检查并为所有TCP和UDP通信打开了端口1099、60001和60002。

有人可以帮忙吗？

Answer 1

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

然后以这种方式控制：

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

Answer 2

您使用了错误的属性，需要修改server.rmi.port

您需要为不同的客户端引擎使用不同的端口，才能：

启动从站1：

jmeter-server -Djava.rmi.server.hostname=127.0.0.1 -Dserver.rmi.port=60001

启动从站2：

jmeter-server -Djava.rmi.server.hostname=127.0.0.1 -Dserver.rmi.port=60002

启动主文档：

jmeter -Jremote_hosts=127.0.0.1:60001,127.0.0.1:60002 -r -n -t test.jmx -l result.jtl

将127.0.0.1替换为您有从属实例的计算机的IP地址（如果与主实例不同）

您的“需求”根本没有意义，因为在同一台计算机上拥有2个JMeter从属实例在性能上比拥有1个实例更糟糕
According to JMeter best practices you should be using the latest version of JMeter，所以请考虑升级到JMeter 5.2.1
