Chapter 7. Registering Clients to the Load Balancer
To balance the load of network traffic from clients, you must register the clients to the load balancer.
To register clients, proceed with one of the following procedures:
7.1. Registering Clients Using Host Registration
You can register hosts with Satellite using the host registration feature, the Satellite API, or Hammer CLI.
Procedure
- In the Satellite web UI, navigate to Hosts > Register Host.
- Click Generate to create the registration command.
- Click on the files icon to copy the command to your clipboard.
- Log in to the host you want register and run the previously generated command.
Update subscription manager configuration for
rhsm.baseurl
andserver.hostname
:# subscription-manager config \ --rhsm.baseurl=https://loadbalancer.example.com/pulp/content \ --server.hostname=loadbalancer.example.com
-
Check the
/etc/yum.repos.d/redhat.repo
file and ensure that the appropriate repositories have been enabled.
CLI procedure
Generate the host registration command using the Hammer CLI:
# hammer host-registration generate-command \ --activation-keys "My_Activation_Key"
If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the
--insecure
flag to the registration command.# hammer host-registration generate-command \ --activation-keys "My_Activation_Key" \ --insecure true
- Log in to the host you want register and run the previously generated command.
Update subscription manager configuration for
rhsm.baseurl
andserver.hostname
:# subscription-manager config \ --rhsm.baseurl=https://loadbalancer.example.com/pulp/content \ --server.hostname=loadbalancer.example.com
-
Check the
/etc/yum.repos.d/redhat.repo
file and ensure that the appropriate repositories have been enabled.
API procedure
Generate the host registration command using the Satellite API:
# curl -X POST https://satellite.example.com/api/registration_commands \ --user "My_User_Name" \ -H 'Content-Type: application/json' \ -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"] }}'
If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the
--insecure
flag to the registration command.# curl -X POST https://satellite.example.com/api/registration_commands \ --user "My_User_Name" \ -H 'Content-Type: application/json' \ -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"], "insecure": true }}'
Use an activation key to simplify specifying the environments. For more information, see Managing Activation Keys in Managing Content.
To enter a password as command line argument, use
username:password
syntax. Keep in mind this can save the password in the shell history.For more information about registration see Registering a Host to Red Hat Satellite in Managing Hosts.
- Log in to the host you want register and run the previously generated command.
Update subscription manager configuration for
rhsm.baseurl
andserver.hostname
:# subscription-manager config \ --rhsm.baseurl=https://loadbalancer.example.com/pulp/content \ --server.hostname=loadbalancer.example.com
-
Check the
/etc/yum.repos.d/redhat.repo
file and ensure that the appropriate repositories have been enabled.
7.2. (Deprecated) Registering Clients Using the Bootstrap Script
To register clients, enter the following command on the client. You must complete the registration procedure for each client.
Prerequisite
- Ensure that you install the bootstrap script on the client and change file permissions of the script to executable. For more information, see Registering Hosts to Red Hat Satellite Using The Bootstrap Script in Managing Hosts.
Procedure
On Red Hat Enterprise Linux 8, enter the following command:
# /usr/libexec/platform-python bootstrap.py \ --activationkey="My_Activation_Key" \ --enablerepos=satellite-client-6-for-rhel-8-<arch>-rpms \ 1 --force \ 2 --hostgroup="My_Hostgroup" \ --location="My_Location" \ --login=admin \ --organization="My_Organization" \ --puppet-ca-port 8141 \ 3 --server loadbalancer.example.com
On Red Hat Enterprise Linux 7 or 6, enter the following command:
# python bootstrap.py --login=admin \ --activationkey="My_Activation_Key" \ --enablerepos=rhel-7-server-satellite-client-6-rpms \ --force \ 1 --hostgroup="My_Hostgroup" \ --location="My_Location" \ --organization="My_Organization" \ --puppet-ca-port 8141 \ 2 --server loadbalancer.example.com
The script prompts for the password corresponding to the Satellite user name you entered with the --login
option.
7.3. (Deprecated) Registering Clients Manually Using katello-ca-consumer RPM
To register clients manually, complete the following procedure on each client that you want to register.
Procedure
Remove the
katello-ca-consumer
package if it is installed:# dnf remove 'katello-ca-consumer*'
Install the
katello-ca-consumer
package from the load balancer:# dnf install http://loadbalancer.example.com/pub/katello-ca-consumer-latest.noarch.rpm
Register the client and include the
--serverurl
and--baseurl
options:# subscription-manager register \ --activationkey="My_Activation_Key" \ --baseurl=https://loadbalancer.example.com/pulp/content/ \ --org="My_Organization" \ --serverurl=https://loadbalancer.example.com/rhsm
