All of these steps can be performed on the host you want to register.

Step 1: Add EPEL & Foreman repositories

sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo yum install -y https://yum.theforeman.org/client/2.0/el8/x86_64/foreman-client-release-2.0.0-1.el8.noarch.rpm

Step 2: Install subscription manager

sudo yum -y install subscription-manager

Now, download and install ca-consumer package to get a copy of the CA certificates from your Katello/Foreman Server.

export katello_fqdn="katello.example.com"

sudo rpm -Uvh http://$[katello_fqdn]/pub/katello-ca-consumer-latest.noarch.rpm

You should be able to resolve katello.example.com host-name in order to work for above command.

Step 3: Register CentOS Server on Katello Server.

You can register your CentOS server by running following command

sudo subscription-manager register --org="YOURORG" \

--activationkey="ACTIVATION-KEY-NAME"

Note: Replace the inverted commas text to your organization & key details.

Activation key must be created on foreman before running above command.

Step 4: Install katello agent tools

Install the katello-host-tools and katello-agent package which reports errata & package profile info, it does not allow to remotely control clients.

sudo yum -y install katello-host-tools  katello-agent katello-host-tools-tracer

Step 5: Start & enable the katello agent Services.

systemctl start goferd

systemctl enable goferd

Step 6: Update CentOS repositories

Remove or move all of your repositories except redhatrepo which are present in /etc/yum.repos.d/.

cd /etc/yum.repos.d/

sudo mkdir old

sudo mv CentOS-* epel* katello* old/

Use Katello Dashboard to verify that katello-agent is installed.

Hosts->Content Hosts->

For installing a package navigate to Hosts->Content Hosts->Select Host->Packages

Choose package action as “Package Remove” to perform action to delete.

The post How To Subscribe CentOS Server to Katello/Foreman appeared first on Linux Windows and android Tutorials.

In this tutorial, we are going to learn how to sync & store CentOS 8 BaseOS & AppStream repositories on Foreman Katello & Red Hat Satellite. Foreman is used for life cycle management of physical and virtual systems. It is an open source application use for provisioning.

Foreman is the basic foundation form which Red Hat Satellite’s core functionality is derived. Katello is a Foreman plug-in for subscription & repository management. It helps you to assist with storing repositories on your local system and provides a means to subscribe to those repositories & download content.

In case, you don’t have Foreman/Red Hat Satellite, you can follow this tutorial;

Now, move towards our tutorial,

Step 1: Creating a Product

Create a product on CLI or from the web console.

From CLI:

List organizations

hammer organization list

Create Product

hammer product create --organization-id 1 \

From Web Console

Go to Products> Create Product

Type your product details & click the save button to finish creating your product.

Step 2: Import CentOS 8 GPG Key

From CLI

mkdir /etc/pki/rpm-gpg/import/
 cd /etc/pki/rpm-gpg/import/
 wget https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
 hammer gpg create --organization-id 1 \
   --key "RPM-GPG-KEY-CentOS-Official" \
   --name "RPM-GPG-KEY-CentOS-8"

Navigate to Content > Credential > New Content Credential to create key from Web Console.

Provide all information like -Name, Type & Paste the key content or use the below button to upload.

Step 3: Create Repositories

Now you can add the new repositories to the newly created product.

Hammer CLI

BaseOS repository

 hammer repository create 
--organization-id 1 \   
--product "CentOS 8 Linux for x86_64" \   
--name "CentOS 8 Base RPMS" \   --label "CentOS_8_Base_RPMS" \   
--content-type "yum" \   --download-policy "on_demand" \   
--gpg-key "RPM-GPG-KEY-CentOS-8" \   --url "http://centos.mirror.liquidtelecom.com/8/BaseOS/x86_64/os/" \   
--mirror-on-sync "no" 

AppStream repository

hammer repository create --organization-id 1 \
   --product "CentOS 8 Linux for x86_64" \
   --name "CentOS 8 AppStream RPMS" \
   --label "CentOS_8_AppStream_RPMS" \
   --content-type "yum" \
   --download-policy "on_demand" \
   --gpg-key "RPM-GPG-KEY-CentOS-8" \

   --mirror-on-sync "no"

PowerTools repository

hammer repository create --organization-id 1 \

  --product "CentOS 8 Linux for x86_64" \

  --name "CentOS 8 PowerTools RPMS" \

  --label "CentOS_8_PowerTools_RPMS" \

  --content-type "yum" \

  --download-policy "on_demand" \

  --gpg-key "RPM-GPG-KEY-CentOS-8" \

  --url "http://centos.mirror.liquidtelecom.com/8/PowerTools/x86_64/os/" \

  --mirror-on-sync "no"

Centosplus repository

hammer repository create --organization-id 1 \
   --product "CentOS 8 Linux for x86_64" \
   --name "CentOS 8 centosplus RPMS" \
   --label "CentOS_8_centosplus_RPMS" \
   --content-type "yum" \
   --download-policy "on_demand" \
   --gpg-key "RPM-GPG-KEY-CentOS-8" \
   --url "http://centos.mirror.liquidtelecom.com/8/centosplus/x86_64/os/" \
   --mirror-on-sync "no"

Extras repository

hammer repository create --organization-id 1 \

  --product "CentOS 8 Linux for x86_64" \

  --gpg-key "RPM-GPG-KEY-CentOS-8" \

  --url "http://centos.mirror.liquidtelecom.com/8/extras/x86_64/os/" \

  --mirror-on-sync "no"

Run the following command to list & view the repositories in the Product.

hammer repository list 
--organization-id 1 
--product "CentOS Linux for x86_64"

 $ hammer repository list --organization-id 1 --product "CentOS 8 Linux for x86_64" 
---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- 
ID | NAME                     | PRODUCT                   | CONTENT TYPE | URL 
---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- 
65 | CentOS 8 AppStream RPMS  | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/AppStream/x86_64/os/ 
64 | CentOS 8 Base RPMS       | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/BaseOS/x86_64/os/ 
67 | CentOS 8 centosplus RPMS | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/centosplus/x86_64/os/

66 | CentOS 8 PowerTools RPMS | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/PowerTools/x86_64/os/ 
---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- 

From Web Console

We can achieve the same from the Foreman / Satellite web dashboard.

To achieve this go to Products > Repositories.

Step 4: Sync Repositories

Now you are able to Sync your repositories to your local Satellite / Katello server.

From CLI

list repositories

 $ hammer repository list --organization-id 1 --product "CentOS 8 Linux for x86_64" 
---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- ID | NAME                     | PRODUCT                   | CONTENT TYPE | URL 
---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- 
65 | CentOS 8 AppStream RPMS  | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/AppStream/x86_64/os/ 
64 | CentOS 8 Base RPMS       | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/BaseOS/x86_64/os/ 
67 | CentOS 8 centosplus RPMS | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/centosplus/x86_64/os/ 
68 | CentOS 8 extras RPMS     | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/extras/x86_64/os/ 
66 | CentOS 8 PowerTools RPMS | CentOS 8 Linux for x86_64 | yum          | http://centos.mirror.liquidtelecom.com/8/PowerTools/x86_64/os/
 ---|--------------------------|---------------------------|--------------|--------------------------------------------------------------- 

Look over th IDs then loop through to sync the repositories.

for i in $(seq 64 68); do \

  hammer repository synchronize --async --organization-id 1 \

  --product "CentOS 8 Linux for x86_64" \

  --id "$i"; \

  done

Make sure status is working properly.

 $ hammer product list  --name "CentOS 8 Linux for x86_64" --organization-id 1 
---|---------------------------|----------------------------------------|---------------|--------------|------------------ ID | NAME                      | DESCRIPTION                            | ORGANIZATION  | REPOSITORIES | SYNC STATE 
---|---------------------------|----------------------------------------|---------------|--------------|------------------ 
37 | CentOS 8 Linux for x86_64 | Repositories for CentOS 8 Linux x86_64 | Mycompany LTD | 5            | Syncing Complete. 
---|---------------------------|----------------------------------------|---------------|--------------|------------------ 

You can also run a sync from web console dashboard.

Step 5: Create a Content View

Follow this command to create content view

 hammer content-view create --organization-id 1 \
--name "CentOS_8" \   
--description "Content view for CentOS 8" 

Add repositories to Content View

for i in $(seq 64 68); do \   
hammer content-view add-repository --organization-id 1 \   
--name "CentOS_8" \   
--product "CentOS 8 Linux for x86_64" \   
--repository-id "$i"; \   
done 

Step 7: Publish Content View

 hammer content-view publish --organization-id 1 \   
--name "CentOS_8" \   
--description "Publishing repositories" 

Create an Activation Key

 $ hammer lifecycle-environment list --organization-id 1 
---|---------|------ 
ID | NAME    | PRIOR 
---|---------|------ 
1  | Library | 
---|---------|------ 

$ hammer activation-key create --organization-id 1 \
   --name "centos8" \
   --description "CentOS 8 Activation Key" \
   --lifecycle-environment "Library" \
   --content-view "CentOS_8" \
   --unlimited-hosts
 $ hammer activation-key list --organization-id 1
 ---|-----------------|------------------|-----------------------|--------------------------
  ID | NAME            | HOST LIMIT       | LIFECYCLE ENVIRONMENT | CONTENT VIEW              ---|-----------------|------------------|-----------------------|-------------------------- 
1  | centos7         | 0 of Unlimited   |                       |                           2  | centos8         | 0 of Unlimited   |                       |                           ---|-----------------|------------------|-----------------------|-------------------------- 

Step 9: Add Subscription to Activation Key

hammer subscription list --organization-id 1

 hammer activation-key add-subscription --organization-id 1 \   
--name "centos8" \   
--quantity "1" \   
--subscription-id "164" 

Where 164 is the id of the subscription shown by the last command.
