Centos 8 is Available for All Syncweb Clients

On September 25, 2019, the new version CentOS 8 and CentOS 8 Stream was released. The Syncweb team has already added the ability to install CentOS 8 on our VPS.

We'll highlight the interesting new features of the release:

Linux Kernel 4.18.0.

This release uses newer Linux kernel version 4.18.0 as opposed to CentOS 7, which used the Linux kernel version 3.10.0. There are many differences, among the key ones we can highlight the revision of the network subsystem, virtualization and security, disk subsystem, memory and system services, as well as support for modern devices (drivers). More details about the new features of the kernel can be found on the official website.

Chronyd

Only the chronyd daemon is now used for time synchronization, ntp is no longer supported.

Nftables package filter.

The new nftables package filter is used, which replaced such packages as iptables, ip6tables, arptables, ebtables, allowing to work with ipv4 and ipv6 protocols from one package. Firewalld also uses nftables now.

New package manager.

The new release uses the new DNF-based package manager YUM v4. Among the key features compared to YUM v3, used in CentOS 7, we can highlight the increased performance, support for modular content, API.

RPM

The RPM packet has been updated to version 4.14. New features include package check-up before installation, dependencies support, trigger support, more than 4GB of files.

Python 3.

Now the default version of python is 3.6, and the python3 package is now used for installation, while python2 is used to install version 2.7. There is no python command now, but you can create it yourself. Developers recommend rewriting existing products to use python3, as support for python2 may end in the near future.

DBMS.

Now MariaDB does not replace MySQL, MySQL database is a standalone package. At the moment, the DBMS versions are:

• MySQL 8.0
• MariaDB 10.3
• PostgreSQL 10 и 9.6
• Redis 5.0

NoSQL database MpngoDB was not added because it has a Server Side Public License (SSPL).

Cockpit.

The web console is now installed and is running on port 9090 by default, allowing you to configure many different system settings.

Single nobody user.

In CentOS 7, there were two users, namely nobody with ID 99 and nfsnobody with ID 65534, now it is one nobody user with ID 65534.

The Docker container security and compliance utility is not supported.

There is currently no oscap-docker utility support because the OpenSCAP Docker and Atomic commands are not available.

NFS.

NFS v3 is no longer available over UDP, only TCP. The configuration file was moved from /etc/sysconfig/nfs to /etc/nfs.conf.

We haven’t listed all that is new in the release of CentOS 8, but you can easily see the full list on the official page.
