Installing Jenkins on AlmaLinux 9: A Simple Guide
Jenkins, a free and open-source automation server, has been successfully deployed on AlmaLinux 9, a community-driven, enterprise-ready alternative to CentOS that is fully binary-compatible with Red Hat Enterprise Linux (RHEL) 9. This combination offers several benefits for continuous integration (CI) and continuous delivery (CD) in an enterprise-grade Linux environment.
Stable, Secure, and Compatible Foundation
AlmaLinux 9 provides a reliable base for Jenkins to run critical CI/CD pipelines with minimal disruptions. As an RHEL-compatible operating system designed for long-term production workloads, it offers the enterprise-grade stability and security needed for Jenkins to automate build, test, and deployment processes efficiently.
Integration with Modern Technologies
AlmaLinux 9 supports contemporary software stacks (LAMP, LEMP, Java, Node.js, Python) that Jenkins often integrates with to build and deploy applications. This compatibility enhances smooth automation across various project types.
Automation and Scalability
Running Jenkins on AlmaLinux 9 allows leveraging the OS’s efficient resource management and scalability features in enterprise environments. AlmaLinux’s minimal overhead helps Jenkins maintain high performance under load.
Security Integration
AlmaLinux 9 includes SELinux and hardened security policies by default, helping enforce security best practices for Jenkins pipelines, reducing risk during automated deployment workflows.
Open-Source Community Support
Both Jenkins and AlmaLinux benefit from active open-source communities, enabling quick updates, patches, and integration of new tools essential for continuous delivery pipelines.
Ease of Integration with DevOps Tools
AlmaLinux 9’s compatibility with popular DevOps tools like Ansible, Terraform, and Podman complements Jenkins CI/CD workflows, enabling flexible, automated infrastructure provisioning and containerized deployments.
Cloud-Ready Platform
AlmaLinux 9 is suitable for cloud environments (AWS, Azure) where Jenkins is frequently deployed to run scalable CI/CD pipelines, benefiting from AlmaLinux's consistent performance and security optimizations.
Installing Jenkins on AlmaLinux 9
To install Jenkins on AlmaLinux 9, follow these steps:
- Import the official GPG key for the Jenkins repository:
- Add the Jenkins repository:
- Install OpenJDK 17, which is required for Jenkins:
- Install the Jenkins service:
- Start Jenkins immediately and enable it to start on boot:
- Access the Jenkins web interface using a browser at . The initial admin password for Jenkins can be obtained during the installation process.
- Perform a suggested plugins installation, admin user creation, and setup wizard completion.
By following these steps, you can successfully install Jenkins on AlmaLinux 9 and harness its automation capabilities within an enterprise-grade Linux environment.
Data-and-cloud-computing platforms like Amazon Web Services (AWS) and Microsoft Azure can benefit from the cloud-ready nature of AlmaLinux 9 when deploying Jenkins for scalable continuous integration (CI) and continuous delivery (CD) pipelines.
Furthermore, the integration of Jenkins with technology such as Ansible, Terraform, and Podman on AlmaLinux 9 offers smoother automation and flexible, automated infrastructure provisioning as part of the overall CI/CD process.
