For CentOS, the hits keep coming, CentOS 8.0 released

CentOS 8 is a downstream rebuild of the RHEL 8 release and includes a plethora of new additions and significant upgrades that we shall discuss in this article.

Today, the CentOS Linux project announced the release and availability of CentOS 8.0 (1905), fresh on the heels of their release of CentOS Linux 7.7 (1908) just a week ago.

The CentOS 8 Linux distro is a derivative of the Red Hat Enterprise (RHEL) 8.0 source code.   Red Hat Enterprise (RHEL) 8.0 was released earlier this year in May.

CentOS 8 should not be confused with CentOS Stream, also released today.  CentOS Stream is a “rolling preview” of future Red Hat Enterprise Linux kernels and features intended for developers and early adopters.

CentOS 8, on the other hand, is a downstream rebuild of the RHEL 8 release.

The CentOS Linux 8 release includes a plethora of new additions and significant upgrades, including:

  • Content is available via two repositories, the BaseOS repository, and the Application Stream, or AppStream repository.  The BaseOS repository gives users the parts of the CentOS 8 that allow running user spaces on not only physical hardware but also a container, a cloud instance, or a virtual machine.  The AppStream provides all applications a CentOS user might want to run in any of these various user spaces.
  • Podman is the new CentOS 8 Linux Container tool.  It replaces Mobdy and Docker.  While Mobdy and Docker depended on daemons and root to run, Podman is daemonless.
  • Like its predecessor CentOS 7.x, CentOS 8.0 includes Cockpit the powerful, web-based admin GUI tool.
  • CentOS Desktop with Wayland and Xorg.  While Wayland is the default CentOS 8.0 windows manager, users may still use Xorg, instead.
  • System-wide cryptographic policies can be set for TLS, Kerberos, SSH, etc. via the update-crypto-policies command.
  • The updated TCP stack version 4.16 is native in CentOS 8.0, which can increase your internet speed (through via NV and BBR congestion control).
  • DNF replaces Yum as the default CentOS 8.0 package manager.  CentOS 8.0 also includes Yum version 4.0, which uses DNF technology as its back end.
  • Other applications and packages also updated include Ansible, Firefox, PHP, OpenSSH, Nginx, MySQL, and a host of others.

CentOS 8.0 is available for the x86_64, i386, armhp, aarch64, ppc64, POWER9, and ppc64le architectures.

Look for a review of CentOS 8.0 from FOSS Linux shortly.
