#$@!@*& Linux Question

[clevalley]

I knew the title would grab some attention.

Before I go off Google'ing and searching the vendor sites...

I am working with CentOS/RedHat ES5 on a project, and want to know if they provide a jumbo patch with all of there patches in a cumulative bundle.

Solaris calls them Jumbo Patches, Microsoft calls them Service Packs... I just want to know if RH or CentOS provides the same thing - and most importantly, where in the hell do you download them from :shrug:

Hi,

I'm a big believer in CentOS -- it's just a recompiled Red Hat, without any support. We bought Red Hat for years, and I realized that I *never* used their support, so finally started using CentOS.

One difference between CentOS and Red Hat, is that CentOS uses the yum (Yellowdog Update Manager) tool to manage updates.

Doing an upgrade/update is as simple as:

$ yum update

Installing a new package (alpine, for example) is as simple as:

$ yum install alpine

and it will resolve and install any dependencies that alpine might require.

What packages are installed on your system:

$ yum list installed

What's available in all repositories:

$ yum list all

Is package xyzzy installed on this computer?

$ yum list installed | grep xyzzy

etc.

This is GOOD stuff, I am going to print it out and put it in my notes...

Solaris uses pkgadd and pkgrm commands (package add, package remove). I also got my butt kicked on mounting a CD yesterday (mount /dev/cdrom /mnt/cdrom), I just have to learn the nuances between the two O/S's - thank God for Google!

What Solaris has is a ginormous tar-ball of patches you can download with a script you run. It goes out and applies what patches you need.

The reason I cannot do YUM is either these machines are standalone or in a secure environment where I do not have internet connectivity to access the patch repositories.

Does Cent or RH have this tar-ball package of patches?

I love it....

 

[clevalley]

I love it....

I did not mean that in a racist way.

That is what we use to call them, as all the files are balled-up in a package using tar.

:BeavisandButtHeadLaughter: He said "balled-up and package" :BeavisandButtHeadLaughter:

Ah.... that changes everything! I'm not sure if they make updates available like that. I guess you could periodically download the CD or DVD ISO images, and perform an update from that. You could either boot from the CD/DVD and just do the upgrade process (versus a clean install), or if you were really slick, I bet you could fool yum into looking on the CD/DVD for everything it needs instead of going out on the Internet(Google could probably help with that). I'd start poking around in /etc/yum.conf and /etc/yum.repos.d if you're interested in the latter. Good luck!

I never thought of that! I am going to start looking in this direction and I am sure other Linux weenies can kick in and to help on this..

Thanks!

[CentOS] CentOS 5.0 - Yum install using the install cd's as the RPM source - Grokbase

not taken that way. i just finished de-toxifying a user's PC and when you posted that, i had a vision of this big ol' tar ball rolling around the PC....

I took it a face value.

Do you have a separate CentOS/RHEL server that is connected to the internet and the boxen in question? If so, setup a repository on that server using wget and createrepo.

Both use YUM (Yellowdog Updater Modified).

Ah, well, I was close, given that I didn't look it up and lost a lot of brain cells over the holidays!

When did RH start using yum? The last version of RH I worked on was EL3. I'm doing Fedora and CentOS these days.

The short answer is NO. The best answer is use yum and just type

yum update​

That will download all the latest patches for every package installed on the system from the repositories defined in the /etc/yum.repo.d directory.

For stand alone systems, you can use a system off the network and still use yum. Install the yum-downloadonly plugin and the use yum with the downloadonly option and the package list to get the latest RPMs for those packages. Then burn the PRMs to a CD or DVD and use

yum localinstall​

with the list of RPMs as the package list. You will either have to install the repository keys or use the option -nogpgcheck.

RHEL5

RHEL5

I thought they started in 4.

This is what I need to do in my RHEL systems in a secure area which are not connected to the internet.

Now, I just have to get this going.

Don't they use up2date?

Mind now, I am not LINUX smart, I just understand Solaris' way of updates.

Gee Ubuntu is:

sudo apt-get update
sudo apt-get dist-upgrade

tar ... Tape Archive .... left over from main frame / tape drive days
