Hopefully, CentOS 7 isn't far behind

Red Hat, Inc. (NYSE: RHT), the world's leading provider of open source solutions, today announced the general availability of Red Hat Enterprise Linux 7, the latest major release of the company’s flagship platform. Red Hat Enterprise Linux 7 not only lays the foundation for the open hybrid cloud and serves enterprise workloads across converged infrastructures, but it also pushes the operating system beyond today’s position as a commodity platform. Built to meet modern datacenter demands along with next-generation IT requirements, Red Hat Enterprise Linux 7 powers the spectrum of enterprise IT, from application containers to cloud services.

Key Red Hat Enterprise Linux 7 features to address next-generation IT needs include:

Enhanced application development, delivery, portability and isolation through Linux Containers, including Docker, across physical, virtual, and cloud deployments as well as development, test and production environments.

Significant file system improvements, including XFS as the default file system, scaling to 500 TB.

Cross-realm trust to easily enable secure access for Microsoft Active Directory users across Microsoft Windows and Red Hat Enterprise Linux domains, providing the flexibility for Red Hat Enterprise Linux to co-exist within heterogeneous datacenters.

Powerful and secure application runtimes and development, delivery and troubleshooting tools, integrated into the platform and container-ready.

Looks like Linux Kernel bumps from 2.6.32 to 3.10 and XFS filesystem by default for RH EL7

I don't have much experience with CentOS or Red hat release, But for you @eva200 when is your expected release of CentOS 7 ?

eva2000 · Jun 11, 2014

No idea but this is CentOS 7 dev blog at http://seven.centos.org for news which I am watching for CentOS 7

edit: http://seven.centos.org/2014/06/congratulations-to-red-hat-for-rhel7/

As for CentOS 7, it’s currently working its way through our build process. As we have updates you’ll be able to follow them here at seven.centos.org. We’ll post updates as regularly as we can to help keep everyone current on the progress.

Oracle Linux 7 beta has been available for some time at https://blogs.oracle.com/linux/entry/oracle_linux_7_beta_is

Exciting times ahead as Centmin Mod currently works with CentOS 6.x and Oracle Linux 6.x since .06 stable release http://centminmod.com/changelog.html#123eva200006.

So will be testing Centmin Mod compatibility with CentOS 7.x and Oracle Linux 7.x whenever they're ready as well

eWeek's mention of MariaDB MySQL default in Red Hat Enterprise Linux 7 http://www.eweek.com/enterprise-app...l-7-with-new-filesystem-docker-support-2.html

With RHEL 7, Red Hat is also making a shift toward a new default open-source database for its users. Instead of the open-source MySQL database, which has been the default since Red Hat's first enterprise release, RHEL 7 now includes the open-source MariaDB as the default database choice. The MySQL database is an open-source technology that was acquired by Oracle as part of its acquisition of Sun Microsystems in 2010. The original creator of MySQL, Monty Widenius, forked the code to create the MariaDB database. In 2013, MariaDB gained commercial support through a merger with SkySQL.

"We work with SkySQL and MariaDB," Dumas said. "MariaDB has a really solid upstream and has been looking at performance improvements that MySQL has been slow to pick up."

Dumas added that, from her perspective, it's a reasonable move to go from MySQL to MariaDB and it shouldn't be big a deal for RHEL users to make the shift. That said, she noted that MySQL is still an optional choice for RHEL 7 users. - See more at: http://www.eweek.com/enterprise-app...em-docker-support-2.html#sthash.3BP0g8UT.dpuf

Looks like Redhat Exterprise Linux 7 will only be supplying a 64bit installer and removing the 32bit installer see http://www.karan.org/blog/2013/12/15/where-is-the-i686-in-rhel-7/ and https://access.redhat.com/site/solutions/509373.

Issue

Will Red Hat continue to support 32-bit applications in the future, for example in Red Hat Enterprise Linux 7?

Are 32-bit libraries provided with Red Hat Enterprise Linux distributions?

Is there a 32-bit DVD ISO to install RHEL 7?

Can I install RHEL 7 on 32-bit hardware?

Will RHEL 7 suppport i386 and i686 (x86) or only x86_64?

Resolution
Red Hat Enterprise Linux 7 will only provide 64-bit ISO's, thus allowing only a 64-bit operating environment. However, 32-bit is supported in the following ways:

RHEL 7 will continue to provide selected libraries in both 32-bit and 64-bit, allowing 32-bit applications to run in the 64-bit RHEL 7 OS environment. This functionality also exists for RHEL 5 & 6 as documented in the knowledge article: How to install 32-bit packages on a 64-bit system

RHEL 7 will continue to support the multilib toolchain, allowing applications to be compiled for both 32-bit and 64-bit.

RHEL 7 can host, using KVM virtualization technology, both 32-bit and 64-bit virtual guest instances of RHEL 5 and RHEL 6.

While RHEL 7 will not natively support 32-bit hardware, certified hardware can be searched in the certified hardware database.

I know for a fact though that Oracle Linux 7 will have both 32bit and 64bit ISO images so at least if you are currently on a CentOS 6.x 32bit low memory based VPS, you have one avenue to continue with 32bit environment.

Now CentOS 7 whether they offer both 32bit and 64bit installers remains to be seen.

Wonder if @Floren has played with Redhat EL7 yet ?

pamamolf · Jun 13, 2014

So does Centos 7 will use the new kernel 3.10?

That's good news to use a new kernel....

Not so good for static files serving and Apache?

eva2000 · Jun 13, 2014

Yeah CentOS 7 will use 3.10 kernel but those benchmarks are on RC1 and beta versions so hard to say until more folks benchmark it
