CentOS Linux Version 7 Released On x86_64

Posted by Unknown on from the keeping-costs-down dept.

An anonymous reader writes "Today, CentOS project unveiled CentOS Linux 7 for 64 bit x86 compatible machines. CentOS conforms fully with Red Hat's redistribution policy and aims to have full functional compatibility with the upstream product released in last month. The new version includes systemd, firewalld, GRUB2, LXC, docker, xfs instead of ext4 filesystem by default. The Linux kernel updated to 3.10.0, support for Linux Containers, 3d graphics drivers out of the box, OpenJDK 7, support for 40G Ethernet cards, installations in UEFI secure Boot mode on compatible hardware and more. See the complete list of features here and here. You can grab this release by visiting the official mirror site or via torrents. On a related note there is also a CentOS Linux 7 installation screencast here."
