Red Hat Enterprise Linux 8.5 已正式发布。此版本带来了许多新功能和改进,帮助简化部署、优化性能并降低环境中的风险。

Red Hat Enterprise Linux 8.5 has been officially released. This version brings many new features and improvements to help simplify deployment, optimize performance, and reduce risks in the environment.
Linux container improvements in RHEL 8.5

RHEL 8.5 continues the tradition of providing new features and improvements for running Linux containers. The tools brought by this version increase flexibility and reduce the inconvenience of running Podman in a wider environment.

Containerized Podman-The RHEL 8 Podman container image (rhel8/podman) is now officially released, which can help unlock the use of Podman on cloud CI/CD systems, WSL2 on Windows, Docker Desktop on macOS, and RHEL 6, 7 and 8 . Developers can also use Podman container images to help develop and run other container images.

By default, the signature of the container image is verified-in RHEL 8.5, the user can pull the container image with confidence. RHEL 8.5 provides out-of-the-box check container image signatures to verify that they are actually from Red Hat and have not been tampered with or manipulated.

Native OverlayFS as a Rootless container user-RHEL 8.5 provides better performance when building and running a Rootless container, and provides native support for OverlayFS.

RHEL 8.5: Easier to manage and deploy

This release continues to focus on simplifying and improving methods for managing and deploying RHEL. RHEL 8.5 introduces many automation and management tools to automate manual tasks, standardize large-scale deployments, and simplify the daily management of its systems.

Enhanced Web console performance indicators-help identify performance issues. Whether you want to identify CPU, disk, or network performance issues, the enhanced indicators provided in the RHEL 8.5 Web console can help solve the problem. In addition, it is easier to export indicator information to the Grafana server.

Ansible module for hardware management-In RHEL 8.5, users can use Ansible to manage the settings of the Intelligent Platform Management Interface (IPMI), such as the power status of the system and the boot sequence of devices.

System roles for VPN and Postfix-You can use system roles to reduce the time required to set up VPN and Postfix.

Part of the management system is to deal with security and policy compliance. To this end, RHEL 8.5 has many features that can help manage security and compliance when deploying new systems or managing existing infrastructure.
SQL Server feature enhancements

Users running Microsoft SQL Server on RHEL will see many enhanced features to help configure, manage, and operate RHEL more effectively.

RHEL system role for Microsoft SQL Server-available for RHEL 8.5. This system role allows IT administrators and DBAs to install, configure, and adjust SQL Server faster in an automated manner.

SQL Server Evaluation API for Red Hat Insights-Helps provide the best user experience for system and database administrators by providing information from Microsoft’s SQL Server Evaluation API. It helps to provide best practices from Microsoft to evaluate the configuration of SQL Server and provide users with the ability to fix problems found through the API.

Support for developers and applications

In the final analysis, RHEL is used to run users’ applications and infrastructure. As a solid foundation for building and running next-generation applications, RHEL 8.5 supports OpenJDK 17 and .NET 6.
