It seems like your question is a bit unclear or incomplete. The phrase "Alibaba Cloud 3 CentOS 8.5.2111?" could mean several things depending on context. Here are some possible interpretations and responses:

🔍 Possible Interpretations:

1. Are you asking about using CentOS 8.5.2111 on Alibaba Cloud ECS instances?

Yes, CentOS 8.5.2111 is a version of the CentOS Linux distribution that was available during that time period (November 2021). Alibaba Cloud provides pre-configured images for various operating systems, including CentOS.

  • You can launch an ECS instance (Elastic Compute Service) on Alibaba Cloud using a CentOS 8.5.2111 image.
  • These images may be provided directly by Alibaba Cloud or imported as custom images if needed.
  • However, note that CentOS 8 reached End of Life (EOL) on December 31, 2021, so it’s generally recommended to use more actively maintained alternatives like:
    • AlmaLinux
    • Rocky Linux
    • Alibaba Cloud Linux (Alibaba’s own OS optimized for cloud environments)

2. Are you referring to "Instance Type" or quantity ("3" = 3 instances)?

Maybe you’re trying to launch 3 CentOS 8.5.2111 instances on Alibaba Cloud?

  • This is possible via the Alibaba Cloud Console, CLI, or Terraform.
  • Just select the CentOS 8.5 image when configuring each instance.

3. Did you mean "Alibaba Cloud + 3 nodes using CentOS 8.5"?

If you’re setting up a cluster (like Kubernetes, Docker Swarm, or Hadoop), and want to use 3 CentOS 8.5.2111 nodes, this setup is doable on Alibaba Cloud.

✅ Recommendation:

Since CentOS 8 is EOL, consider switching to:

  • Alibaba Cloud Linux 3 – fully supported and optimized for ECS.
  • Or CentOS Stream, which is now the upstream for Red Hat Enterprise Linux (RHEL).
  • Alternatively, Rocky Linux 8 or AlmaLinux 8, both binary-compatible with RHEL/CentOS 8.

🧪 How to Check Your CentOS Version

If you’re already running a CentOS instance and want to confirm the version:

cat /etc/centos-release
# OR
rpm --query centos-release

You should see something like:

CentOS Linux release 8.5.2111
