CentOS 7.0 released

Linux News

CentOS 7 was released today, July 7.

CentOS is identical to Red Hat Enterprise Linux (RHEL) with the only exception being the branding text and graphics. CentOS is a fully supported Community ENTerprise Operating System that provides free upgrades and support.

CentOS 7 incorporates several major changes and enhancements. These includes things like systemd and GNOME 3. In addition, the XFS file system is now the default.

Many of the new features in CentOS, such as systemd, have been around for a couple years, most notably in the Fedora distribution. Fedora is the upstream feeder to RHEL and many new RHEL features are first introduced in Fedora.

See http://www.centos.org/ for more details anout CentOS 7.

Theory and Practice of Linux System Administration

This course is intended for trainee or  junior Linux Systems Administrators who wish to advance their knowledge, and administrators of other Unix versions or Windows who wish to become Linux System Administrators. This class is heavily oriented towards hands-on activities. At least half of the class time is allotted to lab projects.

CentOS

This class is taught using CentOS because it is the downstream distribution of Red Hat Enterprise Linux (RHEL) and is identical in every way except for branding. There will be some discussion of the features found in Fedora and which may appear in future versions of RHEL and  CentOS.

See the Theory and Practice of Linux System Administration page for a complete course description and prerequisites.

Linux Servers and Advanced System Administration

This course is intended for experienced Linux System Administrators who wish to learn advanced troubleshooting techniques and server installation and configuration. By the end of the class each student will have a fully working Linux system with a firewall; a name server with forward and reverse zones; a DHCP server; an email server with integrated anti-spam; two working web sites with one a static HTML site and the other a complete WordPress site with a MySQL back end; A MailMan mailing list server; A VNC server; NFS and Samba shares. The student will also learn to build RPM packages.

See the Linux Servers and Advanced System Administration  page for a complete course description and prerequisites.

Theory and Practice of Linux System Administration class, January 20 – 24

Linux News Training

Millennium Technology Consulting LLC, will be running the highly reviewed class, Theory and Practice of Linux System Administration, the week of January 20 – 24.

About this Course

This course is intended for  junior and mid-level Linux Systems Administrators who wish to advance their knowledge, and administrators of other Unix versions or Windows who wish to become Linux System Administrators. This class is heavily oriented towards hands-on activities. At least half of the class time is allotted to lab projects.  Experienced Linux System Administrators also find this class valuable. Taken from my own experiences accumulated during more than 15 years of using Linux, and developed using my knowledge and experience as a course developer and trainer for both IBM, Red Hat, and other companies, this class covers the practical aspects of Linux System Administration. It builds upon the foundation of the “Philosophy of Linux” in a way that helps the student understand how and why things are done as they are.

Our courses are always highly rated and well reviewed. Here are some comments from previous students taken directly from the course evaluation forms.

Course Description

The student will learn about the history of Linux and the philosophy of Linux and how it applies to the everyday tasks that she will be expected to perform. The student will install a current Centos Linux system on common Intel hardware, using various installation options to customize the final result. The students will learn to use the command line interface (CLI) and many basic Linux commands along with the vi editor. More advanced commands such as sed and awk will be covered and combining all of these commands into short command line programs will be discussed and the student will have opportunity to use them in lab projects.

This course covers the Linux boot sequence and the traditional SystemV init scripts as well as an introduction to the new systemd daemon for startup and daemon management. The student will learn to manage users and software packages. Networking, security, processes, filesystems and Logical Volume Management will be covered in detail.

For complete details of this course see the Theory and Practice of Linux System Administration page.

Fedora 15 on the Horizon

News

Fedora 15 is in Beta testing now and will be available—barring unforeseen complications—by the end of May. There are some interesting new features including desktops GNOME 3 and KDE 4.6.

The feature that will probably make the most difference to Linux Administrators and almost none to end users is the new systemd daemon. This “System Daemon” will replace the SystemV Init scripts which have been around forever; it also replaces the much newer Upstart which has barely gotten a toehold.

Fedora, being the sometimes bleeding edge distribution that it is, Fedora 15 will be the first distribution to include systemd.

The primary purpose of systemd is to launch and manage other needed daemons and processes, but it does it much more intelligently by only starting them as they are needed. Thus much of the systemd function can replace that of the Internet Superdaemon, xinetd or inetd, depending upon your distribution. The xinetd daemon simply hangs around waiting for an Internet connection attempt on one of its supported servers such as Telnet. It then starts the appropriate server and passes off the connection to that server and then waits for another connection attempt.

The systemd works much the same way, only not just with network-based services. It works together with UDEV and D-Bus to determine when a local daemon is needed and then starts it. Starting local daemons only when required saves system resources and can significantly improve boot time. This improved boot time is the only thing that most users will notice.

For a little closer look at Fedora 15 see 7.5 Reasons to Look Forward to Fedora 15 at Linux.com.

For all of the gory details of systemd, see http://0pointer.de/blog/projects/systemd.html. This German web site also has an excellent multipart series, systemd for Administrators.
