Following the recent release of Red Hat Enterprise Linux 7.4 comes the new image of CentOS 7, a “version that replaces all previously published content for CentOS Linux 7, so we encourage all users to update their machines,” the developers point out. of the system in the official announcement.

CentOS 7 1708 therefore replaces the last December release and is positioned as the recommended installation medium. For installations in progress it is enough to execute a yum update to be up-to-date -including the August and September updates- and in new installations it is recommended to do it as soon as you finish installing.

For the rest the news of CentOS 7 1708 are the novelties of Red Hat Enterprise Linux 7.4, with special focus on the support of new hardware and everything related to the cloud and containers; saving a few own changes that include various updates and “packages modified by CentOS”. All the data in the release notes.

The download of CentOS 7 1708 is currently available only for x86_64 architectures, in the usual formats: minimal installation and network, DVD, live DVD with GNOME and KDE and an image of 8.1 GB with all the packages of the repositories distribution officers. In the list of replicas you can find a server nearby, although it is best to download by torrent.

The images for the cloud (Vagrant, Cloud and Atomic Host) and the rest are being prepared and will be released in the coming days.

CentOS is the free Linux distribution that offers the most support time. CentOS 7 will remain with support until 2024, so it has 7 years to live.

RHEL

Red Hat has announced the availability of RHEL 7.4, the last major update of the current version of Red Hat Enterprise Linux 7. This time we are mostly improving security and performance in everything related to servers, containers and Cloud.

In terms of security, we can highlight the updated auditing capabilities, which will help administrators simplify the filtering of events recorded by the audit system, gather information on critical events and interpret a large number of records. Other important changes and innovations include the inclusion of USB Guard to protect malicious USB servers, container security improvements through SELinux and OverlayFS, and the SHA-1 algorithm and blowfish-encryption have been marked as obsolete for OpenSSH. cbc

In terms of performance, NVMe Over Fabrics offers an increase in flexibility and reduces consumption when accessing a storage based on high-performance non-volatile memory (NVMe) over Ethernet and Infiniband. With regard to public clouds, boot times have been improved to allow critical applications to start faster. Support has also been added for Elastic Network Adapter (ENA), from Amazon Web Services (AWS), to enable new capabilities at the network level.

At container level, RHEL 7.4 includes the latest version of RHEL Atomic Host, a container host specifically designed to deploy secure and reliable applications as containers through hybrid clouds. In addition to the already mentioned security enhancements supported by SELinux and OverlayFS, full support has been incorporated for the stratification of rpm-ostree packages, thus providing a means to add packages such as monitoring agents and controllers for the host operating system. On the other hand, LiveFS has been introduced as a preview technology, allowing users to install security updates and layer packages without restarting.

RHEL 7.4 has incorporated RHEL System Roles as preview technology. This DevOps tool offers a common management interface across all major versions of RHEL, allowing system administrators to use Ansible automation for large and heterogeneous implementations of the distribution in question.

In addition to maintaining support for a large number of architectures, including IBM Power, IBM z Systems and 64-bit ARM (the latter in preview version), the High Power support has been enabled for the IBM Power Little Endian architecture. , the Resilient Storage Add-Ons, in addition to the execution environment and the Open Container Initiative (OCI) image format.

As you can see, RHEL 7.4 is loaded with new features and this is just a summary. Those who want to know all the details in a complete way can consult the release notes.
