The new version of CentOS 7.0 is currently available. As you know, CentOS is a Red Hat Enterprise Linux derivative which provides a powerful, scalable Linux distribution. CentOS 7 uses the new Kernel 3.10 and the download link is available through its mirror.
CentOS 7.0 comes have the following features:
- XFS is CentOS’s new default file system: This enables you to scale file-systems up to 500 terabytes. You can, however, use Ext4 or other major Linux file systems if you prefer since XFS really only shows to advantage on 1 terabyte disks and larger with multiple processor cores.
- Microsoft Active Directory support: With this you’ll be able to have cross-realm trust Windows, RHEL 7, and CentOS 7 domains. This is ideal if you have users working with heterogeneous operating system-based datacenters or server farms.
- The adoption of OpenLMI. This is a standard remote application programming interface (API). Red Hat has used this to provide unified management tools and a management framework to streamline administration and system configuration.
- Performance Co-Pilot is now included. This is a set of real-time frameworks and services for recording and monitoring system performance. This lets both system administrators and other sub-systems, such as systemd, keep a close eye on what’s actually happening in a CentOS 7 server instance as it happens.
- The arrival of systemd: This is the replacement for init, the old Unix way of starting processes and services on a system and initializing resources. After years of debate, systemd has been adopted by Red Hat, SuSE, Debian, and Ubuntu. It’s become the new default way to start Linux systems. It also incorporates performance profiles and tuning and instrumentation for optimized performance and easy scalability.
