问题描述

我正在尝试非GUI和分布式JMeter负载测试.

I'm trying non-GUI and distributed JMeter load-testing.

在分发之前，我先在本地进行了测试.我在笔记本电脑上安装了JMeter，并针对被测系统设置了一个测试计划.我安装了插件管理器并安装了并发线程插件. 我发现我的JMX文件正确且可以正常工作，因此我决定推出分布式设置.

Before I go distributed, I tested it locally. I installed JMeter on my laptop and setup a testplan targeting the system under test. I installed the plugin manager and install the concurrent thread plugin. I found my JMX file to be correct and working, so I decided to rollout the distributed setting.

我设置了三台用于生成负载的机器:load-1，load-2和load-3.我安装了JMeter，如下所示: 在所有的apt update ; apt upgrade上 apt install jmeter在所有这些上 将我笔记本电脑的/usr/share/jmeter/lib/ext中的JAR复制到了同一目录中的所有JAR中:

I setup three machines for load generation : load-1, load-2 and load-3. I installed JMeter as follow : apt update ; apt upgrade on all of them apt install jmeter on all of them copied the JARs located in /usr/share/jmeter/lib/ext of my laptop to all of them, in the same directory :

jmeter-plugins-casutg-2.1.jar
jmeter-plugins-cmn-jmeter-0.3.jar
jmeter-plugins-manager-0.11.jar

我在其中两个上启动了JMeter服务器，如下所示:

I started the JMeter server on two of them as follow :

export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.21
export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.22

我使用第三个方法开始分布式测试，如下所示:

I use the third one to start the distributed testing as follow :

jmeter -n -t ~/JMeter_API_TestPlan.jmx -R207.112.137.21,207.112.137.22

分布式设置似乎可以正确启动，但是线程启动失败可能是由于找不到类:

The distrubuted setting seems to start correctly, but the thread start fail probably because of a class not being found :

java.lang.ClassNotFoundException:com.blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup(无安全管理器:禁用RMI类加载器)

java.lang.ClassNotFoundException: com.blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup (no security manager: RMI class loader disabled)

我缺少JAR或配置参数吗?

A I missing a JAR or a configuration parameter ?

jmeter.log显示以下内容:

我正在运行Ubuntu 16.04.2 LTS

I'm running Ubuntu 16.04.2 LTS

推荐答案

  1. jmeter-plugins-cmn-jmeter-0.3.jar应该转到"lib"文件夹，而不是"lib/ext"
  2. 您正在使用3年以上的JMeter 2.11，我建议您升级到 JMeter下载页面手动下载JMeter 3.2 (或更高版本) . Ubuntu存储库似乎包含非常过时的JMeter版本
  3. 为避免手动安装插件出现任何问题，我建议使用 JMeter插件管理器
  1. jmeter-plugins-cmn-jmeter-0.3.jar should go to "lib" folder, not to "lib/ext"
  2. You are using JMeter 2.11 which is 3+ years old, I would recommend upgrading to JMeter 3.2 (or later) by manually downloading it from JMeter downloads page. Ubuntu repositories seem to contain very outdated JMeter's version
  3. To avoid any issues with plugins manual installation I would suggest installing the same plugins set on the master host and all the slaves using JMeter Plugins Manager
