Migrating from CentOS6 to RHEL6

There are different tutorial on the net how to migrate from RHEL to CentOS but almost no information about the other way round. It is quite simple and at the end of the day you have only Red Hat Packages installed. you need to copy the following packages from a Red Hat medium and install them: yum localinstall \ rhn-check-1.0.0-87.el6.noarch.rpm \ rhn-client-tools-1.0.0-87.el6.noarch.rpm \ rhnlib-2.5.22-12.el6.noarch.rpm \ rhnsd-4.9.3-2.el6.x86_64.rpm \ rhn-setup-1.0.0-87.el6.noarch.rpm \ yum-3.2.29-30.el6.noarch.rpm \ yum-metadata-parser-1.1.2-16.el6.x86_64.rpm \ yum-rhn-plugin-0.9.1-40.el6.noarch.rpm \ yum-utils-1.1.30-14.el6.noarch.rpm \ sos-2.2-29.el6.noarch.rpm \ Then ….Read More

Some impressive figures about Spacewalk and my two cents

Today, I saw a interessing post on the spacewalk-devel mailing list. Lines of code Spacewalk has 2,908,841 lines of code, created in estimated 843 person years. This means 843 developers are needed to rewrite Spacewalk from scratch in one year! That’s amazing. Number of bugs fixed As stated in the post, the Spacewalk-team fixed 1012 bugs in the year 2010. Some 1061 bugs are still due to be solved, the Spacewalk-team will not running out of work in 2011. See ….Read More

RHEL6 is released!

RHEL6 was just released at 2010-11-10 20:09:50 CET. Quoting Red Hat press relase: Today, we delivered Red Hat Enterprise Linux 6 to the market. @Red Hat: you are so mean! Next time inform your fellows one day in advance to give your fellows the chance to fill the fridges with champagne! I did not checked (yet) the differences between beta 2.1 and GA. I guess the differences are at a minimum. The odd thing is: It seems not be available ….Read More

RHN Satellite 5.4, first analysis

First of all: Where is the Red Hat Press release? Nada, nothing, nichts (yet)…. History As I wrote in my previous post, I’ll keep you posted with my latest findings. In another post, I was speculating about the upstream version. Now, Sat540 seems to be based on Spacewalk 1.2 which is not yet released. I was quite puzzled about that fact. Usually upstream (Fedora) projects are ahead of its commercial counterparts, this time it seems to be the other way ….Read More

Rumours about RHEL6 GA end of October 2010

The latest unofficial rumors about the release date of RHEL6 are pointing to end of October 2010. This is a bit more precise than the official statement “later this year“. There are multiple sources of this rumors, so it can be considered truthful but still not as a fact. Hopefully RHN Satellite 5.4 will be released end of September to prepare the infrastructure to be able to manage RHEL6. Have fun!

RHN Satellite 5.4 release in sight

When analyzing recent Bugzilla-reports and mailing list posts, we can expect a RHN Satellite release quite soon. Why? The main reason for this is the lack of SHA256 support in sat530. Since RHEL6 packages having SHA256 checksums, the release of Satellite 5.4 is a prerequisite for releasing RHEL6. As always there will also be a large load of bugfixes included. Expected new features yum repository syncronising Support for SHA256 checksums Maybe support for SHA384 checksums Support for Oracle 11g databases ….Read More

Experiences with RHEL6 Beta 2.1

Like promised I’ll keep you updated on the RHEL6b2.1. The “official name” is not Beta2.1, it is “Beta 2 refresh”. Why not calling it Beta3? Anyway: The good news first: In contrary to the first release of Beta 2, it works fine again! The first release of Beta2 was quite crappy, it was not installable as a KVM guest. This was obviously due to severe bugs in some virtio drivers. So, what are the news? 1. The bugs in the ….Read More

RHEL6 as a web server

New software versions Today I’m writing about the changes and benefits of RHEL6 as a web server compared to RHEL5. Red Hat is well known for its stable API and ABI over the life-cycle of a major release. For some usage types this is a major problem. Sticking to old version of PHP, MySQL, Tomcat you-name-it-piece-of-software is problematic since web applications are rapidly changing its requirements. Instead of PHP 5.1.6, RHEL6 ships almost up-to-date PHP 5.3.1. Which is good, since ….Read More
