云计算HECSIt seems like your question is a bit unclear or fragmented. Let me try to interpret and address what you might be asking.
You wrote:
"Alibaba Cloud Linux 2 linux3 centos 7 8?"
Based on this, here are possible interpretations of your question:
✅ 1. Are you asking about the differences between:
- Alibaba Cloud Linux 2
- (Possibly Alibaba Cloud Linux 3 – "linux3")
- CentOS 7
- CentOS 8
If so, here’s a breakdown:
| OS | Description | Use Case | Based On |
|---|---|---|---|
| Alibaba Cloud Linux 2 | Alibaba Cloud’s own OS optimized for ECS (Elastic Compute Service). Based on CentOS/RHEL source code. | Cloud environments on Alibaba Cloud | RHEL/CentOS |
| Alibaba Cloud Linux 3 (possibly "linux3") | A newer version of Alibaba Cloud Linux, more modern packages, better performance in cloud. | Cloud usage on Alibaba Cloud | RHEL/CentOS |
| CentOS 7 | Community-supported rebuild of RHEL 7. Old stable version with long-term support (until June 2024). | General-purpose servers | RHEL |
| CentOS 8 | Community-supported rebuild of RHEL 8. Offers newer software stacks but has transitioned to CentOS Stream as of December 2021. | Modern server environments | RHEL |
Key Notes:
- CentOS 8 reached end-of-life (EOL) at the end of 2021, meaning no further updates.
- CentOS Stream is now the future of the CentOS project — it’s a rolling-release distro that sits ahead of RHEL.
- Alibaba Cloud Linux is not a direct replacement for CentOS unless you’re using Alibaba Cloud services. It’s optimized for performance and security within Alibaba Cloud.
✅ 2. Are you trying to choose an OS for use on Alibaba Cloud?
Then here’s a recommendation:
-
Use Alibaba Cloud Linux 2 or 3 if:
- You’re running instances on Alibaba Cloud
- You want better integration, performance, and support from Alibaba
- You don’t need community-driven tools
-
Use CentOS 7 or 8 if:
- You want a consistent experience across different clouds or on-premises
- You’re not using Alibaba-specific features
- You’re aware that CentOS 8 is EOL
⚠️ Note: CentOS 8 is deprecated — consider CentOS Stream or RHEL clone distributions like Rocky Linux or AlmaLinux instead.
✅ 3. Are you having trouble installing/configuring something on Alibaba Cloud Linux 2/3 or CentOS 7/8?
If you’re encountering issues or have specific tasks (like installing Docker, Nginx, Python, etc.), let me know what exactly you’re trying to do, and I can help step-by-step.
Please Clarify:
To give you the most accurate answer, could you please clarify your exact question or goal? For example:
- Are you comparing OS options?
- Are you having trouble with one of them?
- Are you deploying on Alibaba Cloud and choosing an OS?
- Something else?
Let me know!
