Downgrading a package at RHEL 6

10 Ağustos 2011 9:34 PM - Duyuru and Red Hat / omer.sen

With RHEL 6 it is now possible to downgrade (rollback / undo ) a package transaction. For that you use history argument of yum package. To better explain what it is all about here is a few examples:

First lets list what transactions we had since the beginning of the system.

yum history

Updating Red Hat repositories.

And lets make an upgrade of a package using “yum upgrade”


yum -y upgrade openldap-devel

And another “yum history”

2 | root | 2011-06-07 12:28 | Update | 3

As you can see we have a new yum transcation with an ID of 14. On that procedure we have updated openldap-devel and also openldap package is being updated. Lets see how openldap-devel package was upgraded


yum history packages-list openldap-devel
Loaded plugins: presto, product-id, refresh-packagekit, rhnplugin, security, subscription-manager

12 | Update | 2.4.23-15.el6_1.1.x86_64
1 | Install | openldap-devel-2.4.23-15.el6.x86_64

As you can see transaction 14 (ignore transaction 13 for now becase i have done that redo procedure twice) updates opendevel package from 2.4.23-15.el6.x86_64 to 2.4.23-15.el6_1.1.x86_64

Now it is a good time to undo transaction 12

New Subscription Management for RHEL

28 Mart 2011 11:56 AM - Duyuru / omer.sen

With RHEL 5.7 and 6.1 Red Hat has changed the way that it manages subscription on RHN site. As Endersys we wanted to inform you about this

Background

When you make a purchase from Red Hat, you are buying a subscription. A subscription gives you the right to access particular Red Hat services for a period of time on one computer. Once it is applied to a computer, the “right” becomes an “entitlement”. The services you receive include easy access to Red Hat’s software downloads, security and errata updates, access to knowledge resources such as in-depth technical papers, videos and knowledgebase articles, and access to a certain level of technical support — all through our Customer Portal.

You need one subscription for each computer you expect to use Red Hat software or services on. To designate which computer you plan to access Red Hat services from, you must first register that computer, and then you must assign an subscription to that computer directly — a process called Entitling. During the Entitlement process, an Entitlement Certificate is created on your computer. When you download software to your computer from the Red Hat Content Delivery Network, the Entitlement Certificate authenticates and authorizes the computer to receive the requested software services.

Changes to Subscription Management

Prior to this change, Red Hat has used a “pool model” for counting subscriptions, in which we track the total number of subscriptions a customer has purchased, the total number of the customer’s systems that are using subscriptions, and the difference between the two numbers. This model, which will now be called RHN Classic Subscription Management, is simple and effective, but has limitations, including an inability to link a specific subscription with a specific system.

As our product range expands, we’ve needed to change the way we track the subscriptions that our customers purchase and use. Our new model, called RHN Certificate-Based Subscription Management, keeps track of specific subscriptions assigned to specific computers using x.509 certificates.

Red Hat and IPv6 Configuration

04 Şubat 2011 10:27 AM - Duyuru and Red Hat / omer.sen

IPv4 ip address is almost done. All IPv4 are assigned to RIRs by IANA ( http://www.nro.net/news/ipv4-free-pool-depleted ) so we must learn and configure IPv6.

Here is how to do that in Red Hat Enterprise Linux:

Files to configure:

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

And here is the contents of that file

First /etc/sysconfig/network file should contain

NETWORKING_IPV6=yes

then /etc/sysconfig/network-scripts/ifcfg-eth0 file should be edited:


DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
HWADDR=00:30:48:33:bc:33
IPADDR=202.54.1.5
GATEWAY=202.54.1.3
NETMASK=255.255.255.248
IPV6INIT=yes
IPV6ADDR=2607:f0d0:1002:0011:0000:0000:0000:0002
IPV6_DEFAULTGW=2607:f0d0:1002:0011:0000:0000:0000:0001

As you can see above this machine has both IPv6 and IPv4 address which is very reasonable for at least 2 years on transition process. IPV6ADDR and IPV6_DEFAULTGW states. But be aware that there is no IPV6_NETMASK or something like that you have to use IPV6ADDR for that:


IPV6ADDR="3ffe:ffff:0:1::1/128"

More available sysconfig variables for IPv6 is at your RHEL installation at /usr/share/doc/initscripts* directory and /usr/share/doc/initscripts*/sysconfig.txt file

This blog was partly taken from http://www.cyberciti.biz/faq/rhel-redhat-fedora-centos-ipv6-network-configuration/

Red Hat Enterprise Linux 6 (RHEL 6) yenlikleri (Bolüm 1 Üyelik Modeli)

13 Kasım 2010 12:06 PM - Duyuru and Red Hat / omer.sen

Red Hat Enterprise Linux 6 (RHEL 6) ile gelen oldukça fazla özellik mevcut. Bu değişiklikleri iki ana kategoride toplamak gerekirse

1) Lisanslama (aslında üyelik sistemi) değişiklikler.
2) Teknik açıdan yapılan yenilikler/eklentiler.

Bu yazımızda daha çok lisanslama (asıl adı ile üyelik) üzerinde duracağız.

1) Lisanslama (aslında üyelik sistemi) değişiklikler.

RHEL5 teki durum

Bilindiği üzere Red Hat Enterprise Linux lisanslama yöntemi ile değil de üyelik (subscription) yöntemi ile çalışmaktadır. Kısacası ödenen yazılımın her sene tekrar üyeliği gerekmektedir. Bunun avantajı Red Hat’in yeni çıkan ürünlerine hiç extra bir ücret ödenmeden önceki üyeliğinizle indirebilme ve kullanabilmenizdir. RHEL 5 ‘te işletim sistemi olarak iki ana sürüm vardır. RHEL5 ve RHEL 5 AP (Advanced Platform). RHEL 2 cpu soketine kadar , RHEL AP ise 2 cpu soketi (Redhat için core sayısı önemli değildir. Fiziksel cpu adedi önemlidir) üstü için satın alınır ve içinde Cluster, Cluster File System desteği ile beraber gelirdi. Ayrıca RHEL ve RHEL AP için destek seviyeleri mevcuttu. Bunlar Basic, Standard ve Premium olarak adlandırılabilirdi.

RHEL6 daki yeni durum:

RHEL6 da ise bu sistem değişti. Artık RHEL Server olarak adlandırabileceğimiz bir tek ürüne geçildi ve ürün 2 cpu soketi üzerinden fiyatlandırılmaya başlandı (2 cpu soket, 4 cpu soket, 8 cpu soket için ayrı ücretler). Ayrıca Basic, Standard ve Premium yerine Self Support, Standard ve Premium destek seviyeleri geldi. Burada yeni olarak Basic support kaldırılıp yerine Self-Support gelmesi oldu. Self-support un adında da anlaşılabileceği gibi Redhat tarafından sunulan bir support olmuyor. Sadece update alma hakkı veriyor ama case açamıyorsunuz. Self-Support ayrıca sadece iki cpu soketli sistemlere kadar satılmakta daha üstü için sadece Standart ve Premium Support mevcuttur. Ayrıca eğer self-support alınırsa , smart management add-onu’u dışında bir add-on desteklenmemektedir.

Ayrıca daha önceden RHEL AP içinde sunulan Cluster ve Cluster FS artık ayrı Add-on ‘lar halinde satılmaya başlandı.

RHEL 6 ile gelen Add-On ‘lar:

High Availability : Redhat Cluster kurabilmek için alınması gerekiyor
Load Balancer : Redhat Load balancer (LVS tabanlı)
Resilient Storage : GFS Clustered File System için
Scalable File System : XFS dosya sistemi için
High Performance Network : Yüksek veri transfer hızı gerektiren sistemler için (RoCE)
Smart Management : Eskiden RHEL Satellite için kullanılan ve ayrı ayrı satılan Management Module, Provisioning Module ve Monitoring module artık bu ad altında tek bir Add-on olarak sunulmakta.

Bu arada Resilient Storage Add-On , High Availability Add-On ‘u da içermektedir. Sadece Resilient Storage Add-On alınarak GFS’li bir Redhat Cluster kurabilirsiniz. Eğer Cluster ortamınızda GFS olmayacaksa sadece High Availability alınabilir. Fakat aynı durum Load balancer için geçerli değildir.

Bütün bunlara ek olarak RHEL 6 Server’da kurulacak sanal makinalar (guest) içinde 1 guest , 4 guest ve unlimited guest olarak 3 farklı çeşit geldi. Bunların da fiyatlandırılmasında (Support Level,CPU Soket sayısı ve Add-on aynı olsa bile) farklılıklar mevcut. Ayrıca self-support’ta sadece 1 guest alınabilir. Eğer daha fazla guest kullanılılacaksa standart veya premium support satın alınmalıdır.
