Installation of Apache JMeter
Now, let's move on to the installation of Apache JMeter in detail. But first, let's see the requirements before the installation of Apache JMeter.
System Requirements
The following are the requirements for the installation of Apache Jmeter:
-
JDK or Java Development Kit: JDK is a must for the installation of JMeter.
-
Operating System or OS: It doesn't have any minimum requirement.
-
Memory: It doesn't have any minimum requirement.
- Disk Space: It doesn't have any minimum requirement.
Steps for the Installation of Apache JMeter
As we have already studied before that, JMeter is a Pure Java Application.
-
The first step is to install the Java SE Development Kit. You can get the latest version from here.
-
After the successful installation, you can verify it by:
-
In Windows/Linux, first, open the Command Prompt or Terminal.
-
Type the command "java -version" and press Enter.
-
If the installation was successful, you will see the following output.
-
After the installation and verification, it's time to move to the next step. The second step is to download the latest version of Apache JMeter. You can download it from here.
-
The installation process is relatively easy and straightforward. You can simply extract the compressed file. Now you can copy and paste the extracted file wherever you want.
Now, let's study some of the most critical JMeter files and directories.
-
/bin: It contains a JMeter script file that helps in starting JMeter.
-
/docs: It has the documentation files of JMeter.
-
/extras: It includes any other related extra files.
-
/lib/: It contains the library of Java necessary for JMeter.
-
/lib/ext: It consists of the core jar files. These files are essential for JMeter and the protocols.
-
/lib/junit: It is the Junit library that is necessary for JMeter.
- /printable_docs: It contains the docs and guide that can be helpful while working with JMeter.
Launching Apache JMeter
After the installation, let's try to launch and verify that our installation is successful.
You can run JMeter in three modes:
-
GUI Mode,
-
Command Line Mode, and
- Server Mode.
Running JMeter in GUI Mode
If you are running the Windows OS, you can just run JMeter by the following steps:
-
First, go to the destination where you installed JMeter.
-
Now click on the "/bin" folder.
-
Inside the /bin folder, click on the "jmeter.bat" to run it.
-
It should look something like this.
Running JMeter in Non-GUI Mode
When you run JMeter in GUI Mode, it consumes more memory than in Non-GUI Mode. So to save the resources, you can also run it in Non-GUI Mode.
Now, let's see how we can start JMeter in Non-GUI mode.
Running JMeter in Command Line Mode
To run the JMeter in Command Line Mode, you need to open a terminal. Now, follow these steps:
-
Go into the "apache-jmeter- 5.5" folder using the "cd" command.
-
Now enter the following command to run JMeter with some parameters to run JMeter.
jmeter -n -t [jmx file] - l [result file] -H [host] -P [port]
Running JMeter in Server Mode
Server Mode has a critical use. We can do distributed testing using the server mode.
To run the JMeter in Server Mode, you need to open a terminal. Now, follow these steps:
-
Go into the "apache-jmeter- 5.5" folder using the "cd" command.
-
Now, move into the "bin" folder again using the "cd" command.
-
Finally, type "jmeter-server" to run JMeter in server mode.
