问题
I'm trying non-GUI and distributed JMeter load-testing.
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.
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
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
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
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 (no security manager: RMI class loader disabled)
A I missing a JAR or a configuration parameter ?
The jmeter.log shows the following :

回答1:
jmeter-plugins-cmn-jmeter-0.3.jarshould go to "lib" folder, not to "lib/ext"- 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 Ubuntu repositories seem to contain very outdated JMeter's version
- 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
