Yay CentOS 7.x is out !

Centmin Mod hasn't been tested with CentOS 7.x and won't work as yet as I put in place in Centmin Mod code specific allowed CentOS versions to run with and 7.x is not on the allowed list yet until I have done proper testing

From http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 looks like they're following Red Hat and only releasing 64bit x86_64 version ISO files. Seems only Oracle Linux 7.x will have both 32bit and 64bit ISO files then.

Also there doesn't seem to be a minimal ISO download like in CentOS 6.x ? Update: CentOS 7.0 Minimal ISO has been released now https://community.centminmod.com/th...ment-for-centos-7-x86_64.718/page-2#post-3948

Code:

Before copying the image to your preferred installation media you should check the sha256sum of the downloaded installation images.

Details on the images is available on the mirrors at
http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt - that file clearly highlights the difference in the images, and when one might be more suiteable than the others.

Interesting statement in bold regarding a direct upgrade path from CentOS 6.5 to CentOS 7.x https://access.redhat.com/site/docu...x-Migration_Planning_Guide-Upgrade_Tools.html

Also all CentOS-7 sources are now hosted at git.centos.org.

Looks like I'd need to configure Centmin Mod's 3rd party YUM repositories for their RHEL 7 and CentOS 7 equivalents

i.e.

• MariaDB YUM repo https://downloads.mariadb.org/mariadb/repositories/#mirror=aarnet_pty_ltd&distro=CentOS (no RHEL 7 / CentOS 7 yet) silly me forgot CentOS 7 and Red Hat 7 default install is MariaDB MySQL !
• EPEL https://fedoraproject.org/wiki/EPEL (only RHEL beta 7 version)
• RPMFORGE http://wiki.centos.org/AdditionalResources/Repositories/RPMForge (no RHEL7 / CentOS 7 version yet)
• AXIVO ??? @Floren ?

 

From Migration tool page https://access.redhat.com/documenta...jor_Changes_and_Migration_Considerations.html

System Limitations

Hmmm minimum memory needed for CentOS 7 and Redhat 7 is 1GB to run !. Not sure low memory VPS <512MB would be suited to CentOS 7 and might need to stick with CentOS 6.5 32bit ?

 

ah nice catch @dorobo

guess CentOS 7 isn't suited to 128-256MB VPS installs so need to stick with CentOS 6.5 32bit

 

yes would need to revise that eventually

but i think that only comes up with UNATTENDED=n which should be the case as it's UNATTENDED=y by default

 

Yeah, also waiting on Oracle Linux 7 stable release http://www.oracle.com/us/technologies/linux/product/overview/index.html as I believe they offer both 32bit and 64bit at least they did for their Oracle Linux 7 beta http://www.oracle-base.com/articles/linux/oracle-linux-7-installation.php

Ah from http://lists.centos.org/pipermail/centos-announce/2014-July/020393.html they are working on a minimal install ISO

even a 900+ MB ISO better than 3+ GB

ARM release too and 32bit later !

First time CentOS 7.0 64bit install documented at https://community.centminmod.com/threads/centos-7-0-install-on-virtualbox-guest-server.730/

Also RamNode already announced CentOS 7.0 KVM ISO templates on twitter https://twitter.com/RamNode/status/486337247638065152

 

well Centmin Mod is far from ready for CentOS 7.0 right now, working on dual .08 beta Github branches though one for CentOS 7.0 support

 

From https://access.redhat.com/documenta...terprise_Linux-7.0_Release_Notes-Storage.html

Parallel NFS sounds interesting

 

useful systemd cheat sheet at https://community.centminmod.com/th...all-on-virtualbox-guest-server.730/#post-3454

 

systemd is going to really mess up all the Centmin Mod shortcut commands and some custom existing init.d scripts used.. will be fun supporting both CentOS 6.5 and 7.0 methods heh
