The combination offers developers access to cutting-edge packages while maintaining system stability through user-friendly package management. This comprehensive guide will walk you through every step of installing WildFly on Manjaro, from initial system preparation to advanced configuration options.

Installing WildFly on Manjaro requires careful attention to system requirements, security considerations, and proper configuration management. The process involves setting up Java dependencies, creating dedicated user accounts, configuring systemd services, and implementing security best practices. By following this detailed tutorial, you’ll establish a production-ready WildFly environment optimized for performance and security.

Prerequisites and System Requirements

System Requirements

Before beginning the WildFly installation process, verify that your Manjaro system meets the minimum hardware specifications. WildFly requires at least 2GB of RAM for basic operation, though 4GB or more is recommended for production environments. CPU requirements are modest, with any modern multi-core processor providing adequate performance.

Storage considerations are equally important. Allocate at least 1GB of disk space for WildFly installation files, configuration data, and log files. Additional space will be required for deployed applications and their associated data. SSD storage significantly improves application startup times and overall system responsiveness.

Network connectivity is essential for downloading installation packages and managing remote deployments. Ensure your Manjaro system has reliable internet access and can resolve DNS queries properly. Consider bandwidth requirements if you plan to deploy large applications or handle significant user traffic.

Required Software Dependencies

Java Runtime Environment serves as the foundation for WildFly operation. The application server requires Java 11 or higher, with OpenJDK being the preferred implementation on Linux systems. Oracle JDK remains compatible but introduces licensing considerations for commercial deployments.

Version compatibility plays a crucial role in system stability. WildFly 27.x and later versions require Java 11 as the minimum runtime, while newer releases support Java 17 and Java 21. Selecting the appropriate Java version ensures optimal performance and long-term support.

Maven installation becomes necessary for development workflows and application building. While not strictly required for basic WildFly operation, Maven simplifies dependency management and project structure organization for Java applications.

User Permissions and Access

Administrative privileges are required during the initial installation phase. Sudo access enables package installation, user account creation, and system service configuration. Plan to run installation commands with elevated privileges while maintaining security best practices.

Security considerations extend beyond basic access control. Running WildFly as a dedicated non-root user follows the principle of least privilege, reducing potential security risks. This approach contains application processes within restricted user contexts, limiting system exposure.

User account preparation involves creating dedicated system accounts for WildFly operation. These accounts should have minimal system privileges while maintaining necessary access to application directories and configuration files.

Pre-Installation Checklist

System updates ensure compatibility with latest security patches and package versions. Execute a complete system refresh using Pacman package manager before beginning WildFly installation. This process eliminates potential conflicts with outdated system components.

Firewall configuration planning prevents connectivity issues after installation. Identify required ports for WildFly web interface (8080) and management console (9990). Document any additional ports needed for clustering or remote management features.

Network connectivity verification confirms internet access for package downloads and repository synchronization. Test DNS resolution and bandwidth availability to ensure smooth installation progress.

Backup recommendations include creating system snapshots or configuration backups before major installations. While WildFly installation rarely impacts system stability, maintaining recovery options provides peace of mind during complex installations.

Installing Java OpenJDK

Updating System Packages

Begin by refreshing your Manjaro package repositories to ensure access to the latest software versions. Open a terminal and execute the following commands:

sudo pacman -Syu

This command synchronizes package databases and upgrades installed packages to their latest versions. The process may take several minutes depending on your system’s last update and available updates.

Repository synchronization ensures compatibility between system components and newly installed packages. Pay attention to any warnings or conflicts reported during the update process. Address these issues before proceeding with Java installation.

Installing OpenJDK

Install OpenJDK using Pacman package manager with the following command:

sudo pacman -S jdk-openjdk

This command installs the default OpenJDK version available in Manjaro repositories. Alternative versions can be installed using specific package names like jdk11-openjdk or jdk17-openjdk depending on your requirements.

Multiple Java version management becomes important in development environments. Manjaro supports concurrent installation of different Java versions, allowing developers to switch between them as needed. Use the archlinux-java utility to manage multiple Java installations.

Java Configuration

Configure the JAVA_HOME environment variable to ensure proper Java detection by WildFly and other applications. Edit your shell configuration file (.bashrc, .zshrc, or system-wide /etc/environment):

export JAVA_HOME=/usr/lib/jvm/default
export PATH=$JAVA_HOME/bin:$PATH

These environment variables establish consistent Java access across your system. The /usr/lib/jvm/default symlink automatically points to the currently selected Java version, simplifying version management.

PATH configuration ensures Java commands are accessible from any directory. The modified PATH variable prioritizes the Java installation directory, preventing conflicts with other Java installations or system utilities.

Testing Java Installation

Verify successful Java installation using command-line validation:

java -version
javac -version

These commands should display version information for both Java runtime and compiler. Version numbers should match your installed OpenJDK release, confirming proper installation and configuration.

Runtime environment validation includes testing Java application execution and compiler functionality. Create a simple test program to verify complete Java toolchain operation:

echo 'public class Test { public static void main(String[] args) { System.out.println("Java working!"); } }' > Test.java
javac Test.java
java Test

Successful execution confirms Java installation readiness for WildFly deployment.

Creating WildFly User and Group

Security Best Practices

Dedicated user accounts provide essential security isolation for application services. Running WildFly as a non-root user limits potential system damage from security vulnerabilities or application errors. This approach follows established security principles used in production environments worldwide.

Security risks associated with root execution include unlimited file system access, network port binding privileges, and system configuration modification capabilities. Dedicated user accounts contain these risks within defined boundaries, protecting system integrity.

The principle of least privilege requires granting only necessary permissions for application operation. WildFly requires read access to configuration files, write access to log directories, and network socket creation permissions. Additional privileges should be avoided to maintain security posture.

User Creation Process

Create a dedicated wildfly group and user account using the following commands:

sudo groupadd wildfly
sudo useradd -g wildfly -d /opt/wildfly -s /bin/false wildfly

The groupadd command establishes a system group for WildFly-related permissions and file ownership. Group-based access control simplifies permission management and allows multiple users to manage WildFly installations when necessary.

User creation parameters include home directory specification (/opt/wildfly) and shell restriction (/bin/false). The restricted shell prevents interactive login while maintaining system account functionality for service operation.

Directory Structure Setup

Create necessary directories for WildFly installation and operation:

sudo mkdir -p /opt/wildfly
sudo chown wildfly:wildfly /opt/wildfly

Directory creation establishes the foundation for WildFly file organization. The /opt/wildfly location follows Linux Filesystem Hierarchy Standard conventions for optional software packages.

Permission configuration ensures proper file access rights for the wildfly user. Ownership assignment prevents permission conflicts during installation and operation phases.

User Account Verification

Confirm successful user account creation using system utilities:

id wildfly
getent passwd wildfly

These commands display user identification information and account details. Verify that the wildfly user belongs to the correct group and has appropriate home directory assignment.

Testing user switching capabilities ensures service operation compatibility:

sudo -u wildfly whoami

This command should return “wildfly” confirming successful user context switching for service operations.

Downloading and Installing WildFly
