How to install Oracle GraalVM Enterprise Edition 22 on RHEL 8 and run Java/C/C++/nodeJS
0In this video we are going to see how to install Oracle GraalVM Enterprise Edition 22 on Red hat Enterprise Linux 8.
Installation Method (for Components) will be both Online and Offline.
Prerequisites: gcc, glibc, zlib-devel packages should be already installed and Hard disk space around 2 to 3 GB.
We will be showing below basic commands in this video.
gu list ---- To check what components are already shipped with your GraalVM installation or what you have already installed.
gu available ---- To check what components are available for your GraalVM version to install
gu -L install component.jar ---- You can install a component from a local file, Having downloaded the appropriate JAR file, install it with this command.
gu remove ComponentId ---- The command to uninstall the component.
gu remove -D ComponentId ---- add the -D option, which would remove dependent components in addition to those explicitly selected.
gu info ComponentId ---- print the information about specific component (from file, URL, or catalog).
gu --show-ee-token ---- print a saved download token
Next we will be
1. Compile a Java application ahead-of-time into a native executable.
2. Compile and Run C Program using LLVM (Clang).
3. Compile and Run C++ Program using LLVM (Clang++).
4. Run Node.js program
Here I am using Oracle GraalVM Enterprise Edition 22.3.2 Linux x86 for Java 17

Get started with GraalVM – is a high-performance JDK designed to accelerate Java application performance while consuming fewer resources. GraalVM offers two ways to run Java applications: on the HotSpot JVM with Graal just-in-time (JIT) compiler or as an ahead-of-time (AOT) compiled native executable. Besides Java, it provides runtimes for JavaScript, Ruby, Python, and a number of other popular languages. GraalVM’s polyglot capabilities make it possible to mix programming languages in a single application while eliminating any foreign language call costs.
Supported Functionalities
The base distribution of GraalVM Community Edition for Linux platforms includes OpenJDK with the GraalVM compiler enabled. The base installation can be additionally extended with:
Tools/Utilities:
Native Image – a technology to compile an application ahead-of-time into a native executable
LLVM toolchain – a set of tools and APIs for compiling native programs to bitcode that can be executed with on the GraalVM runtime
Language runtimes:
Java,JavaScript,Node.js,LLVM (C and C++)
IMPORTANT NOTE ON TOKEN for Oracle GraalVM EE Components downloads:
You will see a message to provide your valid email address or input your download token and press ENTER. Supposedly,
this is your first installation and you have not accepted the license yet. So press ENTER.
Type your valid email address. You will immediately be sent an email to verify your email address and accept the license.
If an email address is not provided, gu will abort the installation and print an error message that no download token was provided.
Go to your email client and review the Oracle Technology Network License Agreement GraalVM Enterprise Edition Including License for Early Adopter Versions.
Accept the license. This way you confirm the license acceptance and generate a download token simultaneously.
Return to the console window and press ENTER to continue. It will ask you where to store the download token on your computer. By default, the download token will be saved in the ~/.gu/config file in the user’s home directory. To confirm the default location, type yes. The download and installation of the component will start.
Once the installation completes, you can continue installing other components using the same command: gu install ComponentId. GraalVM Updater reads your ~/.gu/config and you do not have to re-accept the license.
Consider the following aspects:
A single download token is associated with a single email address.
If you use the same email address to download a GraalVM Enterprise artifact from another computer, the existing download token will become invalid.
You can transfer a download token to another computer, gu will accept it.
You will be asked to re-accept the license only if the license text changes.
The following commands can help you manage a download token:
--email address to print an e-mail address used for generating a download token
--config path to provide the path to a download token
--show-ee-token to print a saved download token
