运行同一主机上的多个 jmeter-server

Question

我想运行 JMeter 以分布式方式。我的要求是在我的从机上应该有多个 jmeter-server 进程运行ning。为了做到这一点，我运行下面的命令。

./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

每次我运行这个命令时，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。但是每次我运行测试都会出现以下错误。

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？

Answer 1

运行这样的服务器：

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

然后控制器这样：

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

你用错了属性，需要修改server.rmi.port

不同的客户端引擎需要使用不同的端口，即：

启动slave 1:

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

启动从机 2：

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

启动大师：

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 替换为您拥有从实例的计算机的 IP 地址（如果它与主实例不同）

你的 "requirement" 根本没有意义，因为在同一台机器上有 2 个 JMeter 从属实例在性能方面比有 1 个实例更差
According to JMeter best practices you should be using the latest version of JMeter so consider upgrading to JMeter 5.2.1
