Configuring JMeter Client & Server

After understanding the above parameters, start configuring the distributed test

Let's take a look at what the official documents say, and add comments to me in Chinese:

1. The firewalls on the systems is turned off. #1. Turn off the firewall

2. All the clients is on the same subnet. #2. All clients are within the same subnet

3. The server is in the same subnet, if 192.x.x.x or 10.x.x.x IP addresses is used. If the server

Doesn ' t use 192 or IP address, there shouldn ' is any problems. #3. Server must also be in the same subnet if 192.x.x.x or 10.x.x.x such IP addresses are used, if serv Er does not use an IP address of 192 or 10, (server is not in the same subnet as client) there will be no problem

4. Make sure JMeter can access the server. #4. Ensure that JMeter has access to the server

5. Make sure to the same version of JMeter on all the systems. Mixing versions

correctly. #5. Ensure that the JMeter versions of the systems are consistent and that different versions of JMeter will not work well

explanation of some terms:

· Master, run in GUI mode while controlling the run of the test, here is the client, the machine where the script is started.

· Slave, running Jmeter-server and receiving instructions from master, sending requests to the target server

Set Jmeter-server:

Open the Jmeter.properties file in the Jmeter_home/bin directory with a text editor and add the host IP that runs jmeter-server to Remote-hosts

remote_hosts=10.0.0.158, 10.0.0.140,localhost

If you do not want your client to run as Jmeter-server, remove localhost from the configuration above.

Note here: It is recommended to use the actual IP instead of localhost, otherwise it is easy to error.

Actual Combat stage:

First, the client starts JMeter in GUI mode and then opens or creates a test script

Second, start all remote server from GUI mode, method: Run-remote all start, see, can also start a single jmeter-server

Third, the use of No-gui method for pressure testing

Jmeter-t "JMS point-to-point.jmx"-n-l testresult.csv-r

-T: from which JMX boot

-N: Stress test in a no-gui manner

-L: Log log

-r: Start remote server (remote_hosts defined in JMeter property), this parameter is not valid in Non-gui mode

So far, the JMeter distributed test has been run through Non-gui mode.

Here's a tip: running JMeter in a distributed way is to run the same test script on all servers, that is, if you're going to 1s up to 100 threads, if you're using 5 machines for distributed testing, debug the script to 20 threads from 1s, otherwise, the 1s has 500 threads, which may differ from your expectations.
