How-To: Deploy Java 21 OpenJDK in an Air-Gapped Environment using yumdownloader

This guide outlines a robust process for deploying Java 21 OpenJDK in environments with no internet connectivity (air-gapped systems). It leverages the yumdownloader utility to efficiently gather all necessary RPM packages and their dependencies from an internet-connected host, enabling a secure and controlled installation on the isolated target system.

Prerequisites

To successfully follow this guide, ensure you have the following:

Internet-Connected Host:

A Linux machine with active internet access.
Crucially, this host should be running the same major and minor version of AlmaLinux, Red Hat Enterprise Linux (RHEL), or a compatible distribution as your air-gapped target. This ensures package compatibility and avoids unforeseen dependency issues.
An active RHEL subscription (if using RHEL) to access official repositories.
Alternative: RHEL 9 on Windows 11 WSL2
For users who prefer a Windows environment, you can set up a Red Hat Enterprise Linux 9 instance within Windows Subsystem for Linux 2 (WSL2) to serve as your internet-connected host. This provides a convenient way to access RHEL repositories and download packages. Remember to obtain the RHEL 9 image from the official Red Hat Developer program.

Air-Gapped Host:

The target Linux machine where Java 21 OpenJDK will be installed. This host must have absolutely no direct internet access.

Secure Transfer Mechanism:

A reliable and secure method to transfer files from the internet-connected host to the air-gapped host. Common methods include:

USB drive (ensure it's clean and secure)
Portable hard drive
Intermediate jump host with strict access controls
Secure local network share (if applicable and isolated)

Step-by-Step Guide

Step 1: Prepare the Internet-Connected Host

On your internet-connected AlmaLinux 9 (or equivalent RHEL/CentOS) host, we will use yumdownloader to collect all required RPMs.

Install yum-utils Package:
The yumdownloader utility is part of the yum-utils package. If it's not already installed, proceed with the installation.

sudo dnf install yum-utils

You will be prompted to confirm the installation. Type y and press Enter.

Verify OpenJDK 21 Package Name:
Before downloading, it's a good practice to confirm the exact package name for Java 21 OpenJDK available in your repositories.

dnf search openjdk

Look for the java-21-openjdk.x86_64 entry, which represents the primary runtime environment package.

Create a Dedicated Download Directory:

Establish a clean, dedicated directory to store all the downloaded RPM packages. This organization is vital for managing the numerous dependency files.

mkdir ~/openjdk-rpm-download

Download Java 21 OpenJDK and its Dependencies:

This is the core step. Use yumdownloader with the --resolve option to automatically identify and download all recursive dependencies of java-21-openjdk. The --downloaddir option directs where these RPMs will be saved.

yumdownloader java-21-openjdk --downloaddir ~/openjdk-rpm-download --resolve

java-21-openjdk: Specifies the primary package for which dependencies are to be resolved.
--downloaddir ~/openjdk-rpm-download: Sets the target directory for all downloaded RPM files.
--resolve: Crucial for air-gapped environments, this option ensures that yumdownloader fetches not only the specified package but also all its direct and indirect dependencies. This guarantees a self-contained set of RPMs for offline installation.

The download process may take some time, as OpenJDK has a significant number of dependencies (as observed in your previous output, around 130 packages).

Verify Downloaded Files:

Once the download operation completes, list the contents of your designated download directory to confirm that all expected RPM files are present.
ls ~/openjdk-rpm-download

You should see a comprehensive list of .rpm files, including java-21-openjdk-*.rpm and java-21-openjdk-headless-*.rpm, alongside all their required libraries and components.

Step 2: Transfer Files to the Air-Gapped Host

Securely move the entire ~/openjdk-rpm-download directory (containing all the collected RPM files) from your internet-connected host to a suitable location on the air-gapped target host.

Example using a USB Drive:

Copy to USB Drive (on Internet Host):

cp -r ~/openjdk-rpm-download /mnt/usb_drive/ # Adjust /mnt/usb_drive/ as per your system

Safely Unmount USB Drive (on Internet Host).
Connect USB Drive (to Air-Gapped Host).

Copy from USB Drive (on Air-Gapped Host):

cp -r /mnt/usb_drive/openjdk-rpm-download /opt/rpms/ # Adjust paths as needed

Step 3: Install Java 21 OpenJDK on the Air-Gapped Host

Manual Dependency Installation (For Learning/Debugging)

For those who wish to understand the dependency chain explicitly or debug specific issues, you can attempt to install packages one by one. This method is generally not recommended for production environments due to its tedious nature and potential for errors, but it is highly valuable for learning and precise dependency mapping.

Navigate to the RPM Directory:

cd /path/to/openjdk-rpm-download # Replace with the actual path where you transferred the RPMs

Attempt to Install the Main Package First:
Start by trying to install the primary java-21-openjdk package. This will reveal its immediate missing dependencies.

sudo rpm -Uvh java-21-openjdk-21.0.8.0.9-1.el9.alma.1.x86_64.rpm

You will likely see an error: Failed dependencies: output, similar to your original notes, listing all the immediate prerequisites. For example:
error: Failed dependencies:

fontconfig(x86-64) is needed by java-21-openjdk-1:21.0.8.0.9-1.el9.alma.1.x86_64

java-21-openjdk-headless(x86-64) = 1:21.0.8.0.9-1.el9.alma.1 is needed by java-21-openjdk-1:21.0.8.0.9-1.el9.alma.1.x86_64

libX11.so.6()(64bit) is needed by java-21-openjdk-1:21.0.8.0.9-1.el9.alma.1.x86_64

... (many more dependencies)

Install Listed Dependencies Iteratively:
Go through the list of failed dependencies and install them one by one. After installing a set of dependencies, try installing the main package again. Repeat this process until all dependencies are satisfied.

Example Iteration:

# Install fontconfig

sudo rpm -Uvh fontconfig-*.rpm

# Install java-21-openjdk-headless (often a major dependency)

sudo rpm -Uvh java-21-openjdk-headless-*.rpm

# Install X11 libraries

sudo rpm -Uvh libX11-*.rpm libXcomposite-*.rpm libXext-*.rpm libXi-*.rpm libXrender-*.rpm libXtst-*.rpm xorg-x11-fonts-Type1-*.rpm

Note: You'll need to identify the exact RPM filenames from your ls ~/openjdk-rpm-download output. Using wildcards (*.rpm) can simplify this if only one version of each dependency is present.

Continue until Main Package Installs:
Keep repeating step 2, installing the newly reported missing dependencies, until sudo rpm -Uvh java-21-openjdk-*.rpm executes successfully without dependency errors.

This manual process provides deep insight into the package's dependencies but is significantly more time-consuming than the recommended sudo rpm -Uvh *.rpm approach, which leverages rpm's internal dependency resolver to handle the order automatically when all files are present.

To install all at once (you are confidence the dependencies don't break others packages), run the rpm -Uvh *.rpm command on the target systems. Prefer to install rpm one by one.

On your air-gapped host, navigate to the directory where you've placed the RPMs and proceed with the installation.

Install All Downloaded RPMs:

Since yumdownloader with --resolve has ensured that all dependencies are available locally, you can perform a single, comprehensive installation of all RPMs in the directory. The rpm -Uvh command will install new packages or upgrade existing ones, providing verbose output (-v) and a progress bar (-h).
sudo rpm -Uvh *.rpm

Note on Dependencies: Unlike your initial attempt to install only java-21-openjdk.rpm which failed due to missing dependencies, installing *.rpm in the directory ensures that rpm can find and satisfy all dependencies from the local set of files. This is the correct and most efficient method for air-gapped installations.

Verify Installation:

After the installation process completes, confirm that Java 21 OpenJDK has been successfully installed and is accessible on your air-gapped system.
java -version

You should observe output similar to the following, confirming the installed Java version:
openjdk version "21.0.8" 2025-07-16

OpenJDK Runtime Environment (build 21.0.8+9-LTS)

OpenJDK 64-Bit Server VM (build 21.0.8+9-LTS, mixed mode, sharing)

Advanced Considerations and Best Practices

Version Consistency: Reiterate the critical importance of ensuring the exact same major and minor Linux distribution version (e.g., AlmaLinux 9.x, RHEL 9.x) on both the internet-connected and air-gapped hosts. Even slight version mismatches can lead to library conflicts or unexpected behavior.
Automation with Ansible: For managing multiple air-gapped systems or automating routine updates, leveraging Ansible is highly recommended. Playbooks can be crafted to:

Execute yumdownloader on a designated "bastion" host with internet access.
Securely transfer the collected RPMs to a local repository or directly to target air-gapped servers (adhering to strict security protocols for data transfer).
Run the rpm -Uvh *.rpm command on the target systems.

Local Repository Management: For larger-scale air-gapped deployments, consider setting up a local YUM/DNF repository. This involves using tools like reposync to mirror external repositories and createrepo to generate metadata, providing a more robust and scalable solution for managing packages offline. While yumdownloader is excellent for individual package sets, a local repository offers greater flexibility for ongoing maintenance.

The OpenJDK packages are now created from a single build which is then packaged for different major versions of Red Hat Enterprise Linux (RHEL). This allows the OpenJDK team to focus their efforts on the development and testing of this single build, rather than having multiple builds which only differ by the platform they were built on.

This does make rebuilding the package slightly more complicated than a normal package. Modifications should be made to the java-21-openjdk-portable.specfile file, which can be found with this README file in the source RPM or installed in the documentation tree by the java-21-openjdk-headless RPM.

Question

How do I use yum to download a package without installing it?

Résolution

There are two ways to download a package without installing it.

One is using the "downloadonly" plugin for yum, the other is using "yumdownloader" utility.
Downloadonly plugin for yum

Install the package including "downloadonly" plugin:

Raw

(RHEL5)
# yum install yum-downloadonly

(RHEL6)
# yum install yum-plugin-downloadonly

Run yum command with "--downloadonly" option as follows:
Raw

# yum install --downloadonly --downloaddir=<directory> <package>

Confirm the RPM files are available in the specified download directory.

Note:

Before using the plugin, check /etc/yum/pluginconf.d/downloadonly.conf to confirm that this plugin is "enabled=1"
This is applicable for "yum install/yum update" and not for "yum groupinstall". Use "yum groupinfo" to identify packages within a specific group.
If only the package name is specified, the latest available package is downloaded (such as sshd). Otherwise, you can specify the full package name and version (such as httpd-2.2.3-22.el5).
If you do not use the --downloaddir option, files are saved by default in /var/cache/yum/ in rhel-{arch}-channel/packages
If desired, you can download multiple packages on the same command.
You still need to re-download the repodata if the repodata expires before you re-use the cache. By default it takes two hours to expire.

Yumdownloader

If downloading a installed package, "yumdownloader" is useful.

Install the yum-utils package:
Raw

# yum install yum-utils

Run the command followed by the desired package:
Raw

# yumdownloader <package>

Note:

The package is saved in the current working directly by default; use the --destdir option to specify an alternate location.
Be sure to add --resolve if you need to download dependencies

########## this example is using Almalinux9

package name java-21-openjdk and other dependencies.
