CentOS被Dropped最新动态

CentOS Lifecycle and Dropped Support Status
CentOS Linux, a community-driven Linux distribution derived from Red Hat Enterprise Linux (RHEL), has undergone significant changes in its support model. The project shifted its focus to CentOS Stream—a rolling-release upstream platform for RHEL—leading to the discontinuation of traditional CentOS Linux releases.

Key lifecycle milestones include:

• CentOS 8: Officially reached End-of-Life (EOL) on December 31, 2021, with no further security updates or support from the CentOS project or Red Hat.
• CentOS 7: Reached EOL on June 30, 2024, after which official repositories and mirrors stopped providing updates. Users were advised to migrate to supported alternatives to avoid security risks.
• CentOS Stream: Transitioned to a rolling-release model, with CentOS Stream 9 receiving long-term support until May 31, 2027 (subject to extension). This version is positioned as a precursor to RHEL releases, offering earlier access to features for developers and enterprises.

Impact of Dropped Support
The EOL of CentOS Linux versions has critical implications for users:

• Security Risks: Without official security updates, systems running CentOS 7/8 are exposed to unpatched vulnerabilities, making them targets for cyberattacks.
• Compatibility Issues: Newer software packages and hardware drivers may no longer support deprecated CentOS versions, leading to functionality breakdowns.
• Loss of Community Support: The CentOS project and third-party forums have reduced assistance for EOL versions, forcing users to rely on paid support or migration.

Recommended Actions for Affected Users
To mitigate risks associated with dropped support, users are encouraged to take proactive steps:

• Migrate to Supported Distributions: The most effective solution is to switch to a distribution with active support. Options include:
  • CentOS Stream: For users wanting to maintain compatibility with RHEL and benefit from rolling updates.
  • Red Hat Enterprise Linux (RHEL): A commercial offering with enterprise-grade support (requires a subscription).
  • Alternative RHEL-based Distros: AlmaLinux, Rocky Linux, or Oracle Linux—free, community-supported alternatives binary-compatible with RHEL.
• Subscribe to Extended Support (Where Available): For CentOS 7 users, services like Alibaba Cloud’s CentOS 7 Extended Security Updates (ELS) offer free critical security patches until June 30, 2025. However, this is a temporary measure and does not replace long-term migration.

Post-Migration Considerations
After migrating to a new distribution, users should:

• Test Compatibility: Verify that existing applications run on the new system to avoid disruptions.
• Update Repository Configurations: Replace old CentOS repository URLs with those of the new distribution to ensure access to updates.
• Monitor Security Advisories: Stay informed about new vulnerabilities and apply patches promptly to maintain system security.
