RedHat发布RHEL 4.5!

RedHat宣布了RHEL 4.5版本的发布！这是怎么回事，这次没有按照常规的采用RHEL X（Update Y）的方式发布，而是采用直接发布4.5的版本。
RHEL 4.5采用了2.6.9-55.EL内核，集成了新的虚拟化技术，从RedHat还是把新内核的东西方向update到了旧版本中。新的系统改进了NFS的性能和infiniband连接性能。

此外另外一些新的改进值得注意：

  • EDAC for Opteron

  • diskdump support for sata_nv and ibmvscsi drivers

  • netdump support to 8139cp driver

  • CIFS updated to 1.45

  • clustering application support through dm device ioctls.



  • Technology preview release of OpenOffice.org 2.0

  • WPA-Supplicant driver now included

  • automounter load balancing with replicated servers

  • Configurable location for core dumps in netdump-server

  • Selectable core dump filtering

  • Microcode update

  • Session keyring initialization PAM module

  • gdm update for new audit system

  • Linux-z/VM monitoring with established z/VM tools

  • DASD awareness for multipath-tools

  • Infiniband update from 1.0 to OFED-1.1 code base

  • Native SAS and STAT devices are now supported

  • Added Alsa support for Broadwater platforms

  • Sealevel 8-port serial cards are now supported

  • Support for SCSI-3 persistent group reservations

  • mdadm support for RAID50

  • GUI iSCSI configuration

  • multipath-tools support for DASD disks


对于RedHat突然发布4.5的意图和意义，目前还不是很明确，可能是要改变一下Update的发布方式，或者其他原因！目前还没有验证关于RHEL 4的用户license是否可以下载4.5的更新。尽快进行验证。

What is DevOPS?

Image
What is DevOPS? As be a DevOPS engineer more than five years in the past, I was always asked what is DevOPS or what is a DevOPS role or what should a DevOPS Engineer do? Or even question like how to be a good DevOPS? What? How? should be the most two frequently questions from almost all organizations. As I am working with  Amazon Web Service  for a long time with my DevOPS career, I tried to get answers from AWS guys frist as they have a special section about AWS DevOPS, also they have AWS DevOPS certificate cources, even though I never try such cources.

This speed enable...

RPM Build Tips!

Now, I am trying to build a Linux system based on the Fedora Core Release! Working with the RPM system in deep.The unpackaged file terminate the build process under RPM 4.x! Unpackaged files message in RPM-4.1 and following RPM version 4.1 and following demonstrate a new behaviour in the rpmbuild process. Previously, a build process might place any number of files, say in the %install stanza, when running the make install part of a Makefile , in the customary /var/tmp/%{name}-root/ BuildRoot (the RPM_BUILD_ROOT ). Once through that part of the Makefile , it can then completely ignore these files in the %files binary packaging stanza. This often happens when an upstream maintainer adds, or deletes items from new directory spurs in the make install , and the change might be missed during an unattended or automated rebuild. This option permits careful packagers to cross check the quality of their packaging. So as a cross check, /usr/lib/rpm/check-files is now enabled during ...
