Instructions for Installing Jenkins on AlmaLinux 9
AlmaLinux 9, a community-driven, enterprise-ready alternative to CentOS, offers a stable and secure platform for running production-grade CI/CD pipelines and automation environments [1]. One of the popular tools that can be installed on AlmaLinux 9 is Jenkins, a free, open-source automation server that enables continuous integration (CI) and continuous delivery (CD) of software.
To install Jenkins on AlmaLinux 9, first, you need to install OpenJDK 17, which is required for Jenkins. This can be done using the following command:
Next, you can install Jenkins by adding the Jenkins repository configuration and running the following command:
Upon installation, Jenkins will be started immediately and enabled to start on boot. SSH access and the Jenkins port are allowed in the firewall for seamless access.
Jenkins runs as a service on AlmaLinux 9, and the web interface is accessed using a browser. The initial admin password for Jenkins is obtained during the installation process. A suggested plugins installation option is available during the setup wizard to streamline the setup process.
Jenkins on AlmaLinux 9 provides a secure, stable, and scalable environment for automating software development pipelines. It benefits from AlmaLinux 9's enterprise-grade compatibility, automation capabilities, and robust CI/CD features.
Key benefits of using Jenkins on AlmaLinux 9 include:
- Stability and Enterprise Compatibility: AlmaLinux 9, as a RHEL-compatible distribution, delivers enterprise-grade reliability and security, ensuring Jenkins runs on a stable and well-supported Linux platform ideal for production CI/CD environments [1][2].
- Automation and Scalability: AlmaLinux 9 supports automation tools like Ansible and Podman, which integrate well with Jenkins pipelines to automate infrastructure provisioning and container deployments, enhancing CI/CD workflows' efficiency and scalability [1][2].
- Security and Update Management: AlmaLinux 9 inherits SELinux security policies and offers predictable, low-downtime updates and resilient architecture, protecting your Jenkins environment and build pipelines from vulnerabilities and downtime [1][2].
- Consistent Environments: AlmaLinux 9 enables maintaining consistency across development, testing, and production environments, reducing integration issues during deployment stages orchestrated by Jenkins [1][2].
- Extensive Ecosystem Support: Jenkins, running on AlmaLinux 9, can leverage a rich ecosystem of tools and packages (e.g., Apache, Nginx, PHP, Python stacks) for building, testing, and deploying diverse applications within your CI/CD pipelines [1].
In addition to the benefits mentioned above, AlmaLinux 9 offers instant server provisioning, root access, and full control for Cloud VPS, making it an ideal choice for CI/CD projects. With a 10-year support until 2032, AlmaLinux 9 provides a long-term, reliable platform for your Jenkins-based CI/CD pipelines.
