CLOUD云Huawei Cloud EulerOS and CentOS are both Linux operating systems, but they are different in origin, purpose, and development model. Here’s a clear comparison to help you understand their relationship and differences:
🔹 1. What is EulerOS?
- Full Name: Huawei EulerOS (also known as openEuler when open-sourced).
- Developer: Huawei.
- Open Source: Yes — the community version is called openEuler.
- Purpose: Designed for enterprise servers, cloud computing, edge computing, and embedded systems. Optimized for performance, security, and reliability in Huawei’s ecosystem.
- Architecture Support: x86_64, ARM64 (especially strong support for Huawei’s Kunpeng processors).
- Use Case: Often used in Huawei Cloud (e.g., as a base for cloud instances), data centers, and high-performance computing.
✅ Huawei Cloud EulerOS is a commercial, enterprise-grade OS provided by Huawei Cloud, based on the openEuler open-source project.
🔹 2. What is CentOS?
- Full Name: Community ENTerprise Operating System.
- Developer: Red Hat (sponsored).
- Based On: Red Hat Enterprise Linux (RHEL) — it’s a rebuild of RHEL source code.
- Purpose: Free, stable, enterprise-class server OS.
- Architecture: x86_64, ARM64, etc.
- Note: CentOS Linux 8 reached end-of-life in 2021. The focus shifted to CentOS Stream, which is a rolling-release version ahead of RHEL (not behind it).
🔹 3. Key Differences
| Feature | Huawei Cloud EulerOS | CentOS |
|---|---|---|
| Base | Based on openEuler (independent, originally inspired by RHEL/CentOS) | Based on RHEL source code |
| Origin | Huawei | Red Hat / Community |
| License | Open source (openEuler), Huawei offers commercial support | Open source (GPL, etc.) |
| Target Use | Cloud, servers, Huawei hardware (e.g., Kunpeng) | General-purpose servers, enterprise |
| ARM64 Optimization | Excellent (especially for Huawei chips) | Good, but not as optimized for Kunpeng |
| Support Lifecycle | Long-term support (LTS) versions provided by Huawei | Varies (CentOS 7: until 2024; Stream: rolling) |
| Package Manager | yum / dnf (RPM-based), similar to RHEL |
yum / dnf (RPM-based) |
🔹 4. Is EulerOS a CentOS Replacement?
Not exactly, but:
- In Huawei Cloud environments, EulerOS is often used instead of CentOS, especially when running on Huawei’s ARM-based Kunpeng servers.
- Because CentOS Linux 8 was discontinued, many organizations (including Huawei) moved to build their own enterprise Linux distributions.
- openEuler has evolved independently and now includes features beyond traditional RHEL clones (e.g., real-time kernel, container acceleration).
🔹 5. Can I Use EulerOS Like CentOS?
Yes, in many ways:
- Similar command-line tools (
yum,systemctl,firewalld). - Compatible with many RPM packages.
- Good for server workloads: web servers, databases, containers.
- But: Some CentOS/RHEL-specific packages or third-party software may need adaptation.
✅ Summary
| Question | Answer |
|---|---|
| Is Huawei Cloud EulerOS the same as CentOS? | ❌ No. It’s a different OS based on openEuler, not RHEL. |
| Is it compatible with CentOS? | ✅ Partially — similar tools and workflows, but not binary-compatible in all cases. |
| Should I use EulerOS on Huawei Cloud? | ✅ Yes — it’s optimized for Huawei hardware and cloud services. |
| Can I migrate from CentOS to EulerOS? | ⚠️ Possible, but requires testing — especially for third-party apps. |

If you’re running workloads on Huawei Cloud, EulerOS is a solid, supported choice — especially for ARM instances. For full RHEL compatibility, CentOS Stream or alternatives like AlmaLinux, Rocky Linux may be better.
