What Certifications Can You Obtain After Learning the Linux System?
Update time：2025-03-14
After learning the Linux system, there are several highly valuable certifications you can obtain. These certifications can significantly enhance your professional recognition in the Linux field and boost your career development. Many people are unsure about which certifications they can pursue. Below, I will introduce some key certifications in detail.
1. Red Hat Certification
The first certification that comes to mind is the Red Hat Certification, which holds a prominent position in the Linux world. Red Hat has been deeply involved in the Linux field for many years, and its certification system is well-established and highly recognized. Red Hat offers several certification levels, including RHCSA (Red Hat Certified System Administrator), RHCE (Red Hat Certified Engineer), and RHCA (Red Hat Certified Architect).
RHCSA is the entry-level certification that focuses on assessing your ability to manage the Red Hat Enterprise Linux system. Candidates need to master user management, such as creating and deleting users, setting different user permissions—critical tasks in multi-user Linux environments within enterprises. In terms of storage management, the exam tests your ability to partition disks, format them, and mount file systems. Earning the RHCSA certification means you have acquired the fundamental skills needed to manage a Red Hat Enterprise Linux system.
If you continue to pursue RHCE, the exam will cover more advanced system configuration and architecture knowledge, such as setting up and managing complex network services and optimizing server performance in a Linux environment. Obtaining an RHCE certification can elevate your expertise in Linux system administration to a higher level.

2. CKA Certification
Another certification you can pursue is the Certified Kubernetes Administrator (CKA). While CKA primarily focuses on Kubernetes container orchestration, it is closely linked to the Linux system. Kubernetes runs on Linux, and proficiency in Linux is a prerequisite for becoming a qualified CKA-certified professional.
During the CKA exam preparation, you need to develop a deep understanding of Linux kernel fundamentals since Kubernetes relies on many Linux kernel features to achieve efficient container management. For instance:
Linux namespaces and control groups (cgroups) are the foundation for container isolation and resource limitation in Kubernetes.
When operating Kubernetes clusters, whether deploying cluster nodes or managing containerized applications, you must be proficient in Linux command-line tools and scripting.
You should be able to use Linux commands to monitor system resource usage, such as top and free, to optimize Kubernetes cluster resource allocation.
Obtaining the CKA certification demonstrates that you have mastered Kubernetes container orchestration while also possessing strong Linux system administration skills, making you highly competitive in the rapidly growing cloud-native industry.
3. Huawei openEuler Certification
You can also pursue Huawei openEuler Certification, which revolves around Huawei’s open-source operating system, openEuler. openEuler is built on the Linux kernel, and this certification aims to cultivate professionals in openEuler system maintenance and management.
The Huawei openEuler certification covers various aspects, including:
Installation: Understanding the Linux system installation process is crucial since openEuler installation is similar to standard Linux installations. You must be able to set up the system based on different hardware environments and business needs.
Configuration: Managing system services, network settings, and performance tuning are all standard Linux system administration tasks, but openEuler has its own configuration methods and specific considerations.
Maintenance and Troubleshooting: Ensuring system stability and resolving issues are essential skills tested in the certification.
By obtaining the Huawei openEuler certification, you will gain professional recognition in the openEuler Linux-based ecosystem. This credential will qualify you for openEuler system maintenance roles within Huawei’s ecosystem and related enterprises, supporting digital transformation and innovation in businesses.
Conclusion
In summary, Red Hat Certification, CKA Certification, and Huawei openEuler Certification are all highly valuable certifications worth pursuing after learning Linux. These certifications cover various aspects of enterprise Linux applications, cloud-native technologies, and specific Linux-based operating systems. Earning these credentials will significantly enhance your Linux expertise, enrich your professional knowledge, and pave the way for a successful career in the Linux field.
