Apache JMeter is a pure Java open-source software for load testing or performance testing. This article introduce based on the establishment of a multi-JMeter from the main vessel of the pressure measurement environment.
JMeter based mirroring of Alpine
JMeter mirroring on introduction and use on the basis of the Alpine, you can see the following:
- https://blog.csdn.net/liumiaocn/article/details/101919657
Based on the measured ambient pressure distributed container
In the container of the pressure sensing JMeter distributed create an environment defined by a compression dynamometer JMX content, by exchanging data volume, using the Master node assignment operation, sensing operation of the specific pressure on the content Slave node. A very simple one can see the main multi FIG distributed pressure from the vessel measurement of the environment.
Test Environment Description
As used herein, a Master node, three main distributed test environment from the Slave nodes 3 formed, for ease of presentation using the same machine, the specific configuration is shown below
| Types of | IP | port | Explanation |
|---|---|---|---|
| Master node | 192.168.31.242 | - | Master control for the node |
| Slave nodes -1 | 192.168.31.242 | 31099 | Slave node 1 for measuring the pressure |
| Slave node -2 | 192.168.31.242 | 31020 | Slave nodes are used for pressure measurement 2 |
| Slave nodes -3 | 192.168.31.242 | 31021 | Slave nodes are used to measure the pressure-3 |

Slave node set and start
In the examples herein, are just starting pressure measurement Slave jmeter of the following three examples to:
- Slave nodes -1
Start command: docker run -d -p 31099: 1099 liumiaocn / jmeter: 5.1.1 jmeter -Dserver.rmi.ssl.disable = true -s -j /tmp/jmeter-slave.log
- Slave node -2
启动命令：docker run -d -p 31020:1099 liumiaocn/jmeter:5.1.1 jmeter -Dserver.rmi.ssl.disable=true -s -j /tmp/jmeter-slave.log
- Slave节点-3
启动命令：docker run -d -p 31021:1099 liumiaocn/jmeter:5.1.1 jmeter -Dserver.rmi.ssl.disable=true -s -j /tmp/jmeter-slave.log
启动示例结果如下所示：
liumiaocn:~ liumiao$ docker run -d -p 31099:1099 liumiaocn/jmeter:5.1.1 jmeter -Dserver.rmi.ssl.disable=true -s -j /tmp/jmeter-slave.log

Master节点设定与启动
Master节点可以只在调用的时候启动（事前需要准备jmx文件），启动示例命令如下所示
Start command examples:
Docker Expediting IT -v $ RUN (pwd) / Data: / Data liumiaocn / JMeter: 5.1.1 JMeter -n -t /data/httprequest.jmx -R & lt 192.168.31.242:31099 -Dserver.rmi.ssl .disable = true -l /tmp/jmeter-result.jtl -j /data/jmeter-test.log -e -o / data / test-result
By executing the above command, Master Slave-1 node notifies the node 1000 perform a stress test of the content. Execution log as follows:
liumiaocn:tmp liumiao$ ls data

Stress Test Report
Stress test report 1000 appeal also been generated, the measurement results of the pressure profiles shown below
to sum up
So we build the vessel by way of a main three-pressure measurements from the environment, in this environment it is more like a so-called Master Client, so in many articles also referred to as the JMeter Client, in order to avoid ambiguity on the understanding, is herein called master, and because many of the primary structure similar to one of its main role is to distribute content to the measured pressure Slave node, as the node is up and running long-running time or temporary, depending on the requirements to get on.
