Chapter 3. Performing Additional Configuration on Satellite Server
3.1. Configuring Satellite Server to consume content from a custom CDN
If you have an internal Content Delivery Network (CDN) or serve content on an accessible web server, you can configure your Satellite Server to consume Red Hat repositories from this CDN server instead of the Red Hat CDN. A CDN server can be any web server that mirrors repositories in the same directory structure as the Red Hat CDN.
You can configure the source of content for each organization. Satellite recognizes automatically which Red Hat repositories from the subscription manifest in your organization are available on your CDN server.
Prerequisites
- You have a CDN server that provides Red Hat content and is accessible by Satellite Server.
- If your CDN server uses HTTPS, ensure you have uploaded the SSL certificate into Satellite. For more information, see Importing Custom SSL Certificates in Managing content.
- You have uploaded a manifest to your organization.
Procedure
- In the Satellite web UI, navigate to Content > Subscriptions.
- Click Manage Manifest.
- Select the CDN Configuration tab.
- Select the Custom CDN tab.
- In the URL field, enter the URL of your CDN server from which you want Satellite Server to consume Red Hat repositories.
- Optional: In the SSL CA Content Credential, select the SSL certificate of the CDN server.
- Click Update.
- You can now enable Red Hat repositories consumed from your internal CDN server.
CLI procedure
- Connect to your Satellite Server using SSH.
Set CDN configuration to your custom CDN server:
# hammer organization configure-cdn --name="My_Organization" \ --type=custom_cdn \ --url https://my-cdn.example.com \ --ssl-ca-credential-id "My_CDN_CA_Cert_ID"

3.2. Configuring Inter-Satellite Synchronization (ISS)
Configure Inter-Satellite Synchronization on your disconnected Satellite Server to provide content in your disconnected network.
3.2.1. Inter-Satellite Synchronization scenarios
Red Hat Satellite uses Inter-Satellite Synchronization (ISS) to synchronize content between two Satellite Servers including those that are air gapped.
You can use ISS in cases such as:
- If you want to copy some but not all content from your Satellite Server to other Satellite Servers. For example, you have content views that your IT department consumes from Satellite Server, and you want to copy content from those content views to other Satellite Servers.
- If you want to copy all Library content from your Satellite Server to other Satellite Servers. For example, you have products and repositories that your IT department consumes from Satellite Server in the Library, and you want to copy all products and repositories in that organization to other Satellite Servers.
You cannot use ISS to synchronize content from Satellite Server to Capsule Server. Capsule Server supports synchronization natively. For more information, see Capsule Server Overview in Overview, concepts, and deployment considerations.
There are different ways of using ISS. The way you can use depends on your multi-server setup that can fall to one of the following scenarios.
3.2.1.1. ISS network sync in a disconnected scenario
In a disconnected scenario, there is the following setup:
- The upstream Satellite Server is connected to the Internet. This server consumes content from the Red Hat Content Delivery Network (CDN) or custom sources.
- The downstream Satellite Server is completely isolated from all external networks.
- The downstream Satellite Server can communicate with a connected upstream Satellite Server over an internal network.
Figure 3.1. Satellite ISS disconnected scenario

You can configure your downstream Satellite Server to synchronize content from the upstream Satellite Server over the network.
3.2.1.2. ISS export sync in an air-gapped scenario
In an air-gapped scenario, there is the following setup:
- The upstream Satellite Server is connected to the Internet. This server consumes content from the Red Hat CDN or custom sources.
- The downstream Satellite Server is completely isolated from all external networks.
- The downstream Satellite Server does not have a network connection to a connected upstream Satellite Server.
Figure 3.2. Satellite ISS air-gapped scenario

The only way for an air-gapped downstream Satellite Server to receive content updates is by exporting payload from the upstream Satellite Server, bringing it physically to the downstream Satellite Server, and importing the payload. For more information, see Synchronizing Content Between Satellite Servers in Managing content.
You can configure your downstream Satellite Server to synchronize content by using exports.
3.2.2. Configuring Satellite Server to synchronize content by using exports
If you deployed your downstream Satellite Server as air gapped, configure your Satellite Server as such to avoid attempts to consume content from a network.
Procedure
- In the Satellite web UI, navigate to Content > Subscriptions.
- Click Manage Manifest.
- Switch to the CDN Configuration tab.
- Select the Export Sync tab.
- Click Update.
CLI procedure
- Log in to your Satellite Server by using SSH.
Set CDN configuration to sync by using exports:
# hammer organization configure-cdn --name="My_Organization" --type=export_sync
Additional resources
- For more information, see Content synchronization by using export and import in Managing content.
3.2.3. Configuring Satellite Server to synchronize content over a network
Configure a downstream Satellite Server to synchronize repositories from a connected upstream Satellite Server over HTTPS.
Prerequisites
- A network connection exists between the upstream Satellite Server and the downstream Satellite Server.
- You imported the subscription manifest on both the upstream and downstream Satellite Server.
- On the upstream Satellite Server, you enabled the required repositories for the organization. For more information, see Enabling Red Hat Repositories in Managing content.
The upstream user is an admin or has the following permissions:
-
view_organizations
-
view_products
-
export_content
-
view_lifecycle_environments
-
view_content_views
-
-
On the downstream Satellite Server, you have imported the SSL certificate of the upstream Satellite Server using the contents of
http://upstream-satellite.example.com/pub/katello-server-ca.crt
. For more information, see Importing SSL Certificates in Managing content. - The downstream user is an admin or has the permissions to create product repositories and organizations.
Procedure
- Navigate to Content > Subscriptions.
- Click Manage Manifest.
- Navigate to the CDN Configuration tab.
- Select the Network Sync tab.
- In the URL field, enter the address of the upstream Satellite Server.
- In the Username, enter your username for upstream login.
- In the Password, enter your password or personal access token for upstream login.
- In the Organization label field, enter the label of the upstream organization.
-
Optional: In the Lifecycle Environment Label field, enter the label of the upstream lifecycle environment. Default is
Library
. -
Optional: In the Content view label field, enter the label of the upstream content view. Default is
Default_Organization_View
. - From the SSL CA Content Credential menu, select a CA certificate used by the upstream Satellite Server.
- Click Update.
- In the Satellite web UI, navigate to Content > Products.
- Select the product that contains the repositories that you want to synchronize.
From the Select Action menu, select Sync Now to synchronize all repositories within the product.
You can also create a synchronization plan to ensure updates on a regular basis. For more information, see Creating a Synchronization Plan in Managing content.
CLI procedure
- Connect to your downstream Satellite Server using SSH.
View information about the upstream CA certificate:
# hammer content-credential show \ --name="My_Upstream_CA_Cert" \ --organization="My_Downstream_Organization"
Note the ID of the CA certificate for the next step.
Set CDN configuration to an upstream Satellite Server:
# hammer organization configure-cdn --name="My_Downstream_Organization" \ --type=network_sync \ --url https://upstream-satellite.example.com \ --username upstream_username --password upstream_password \ --ssl-ca-credential-id "My_Upstream_CA_Cert_ID" \ --upstream-organization-label="_My_Upstream_Organization" \ [--upstream-lifecycle-environment-label="My_Lifecycle_Environment"] \ [--upstream-content-view-label="My_Content_View"]
The default lifecycle environment label is
Library
. The default content view label isDefault_Organization_View
.
3.3. Configuring pull-based transport for remote execution
By default, remote execution uses push-based SSH as the transport mechanism for the Script provider. If your infrastructure prohibits outgoing connections from Satellite Server to hosts, you can use remote execution with pull-based transport instead, because the host initiates the connection to Satellite Server. The use of pull-based transport is not limited to those infrastructures.
The pull-based transport comprises pull-mqtt
mode on Capsules in combination with a pull client running on hosts.
The pull-mqtt
mode works only with the Script provider. Ansible and other providers will continue to use their default transport settings.
Procedure
Enable the pull-based transport on your Satellite Server:
# satellite-installer --foreman-proxy-plugin-remote-execution-script-mode=pull-mqtt
Configure the firewall to allow the MQTT service on port 1883:
# firewall-cmd --add-service=mqtt
Make the changes persistent:
# firewall-cmd --runtime-to-permanent
In
pull-mqtt
mode, hosts subscribe for job notifications to either your Satellite Server or any Capsule Server through which they are registered. Ensure that Satellite Server sends remote execution jobs to that same Satellite Server or Capsule Server:- In the Satellite web UI, navigate to Administer > Settings.
- On the Content tab, set the value of Prefer registered through Capsule for remote execution to Yes.
Next steps
- Configure your hosts for the pull-based transport. For more information, see Transport modes for remote execution in Managing hosts.
3.4. Enabling power management on hosts
To perform power management tasks on hosts using the intelligent platform management interface (IPMI) or a similar protocol, you must enable the baseboard management controller (BMC) module on Satellite Server.
Prerequisites
- All hosts must have a network interface of BMC type. Satellite Server uses this NIC to pass the appropriate credentials to the host. For more information, see Adding a Baseboard Management Controller (BMC) Interface in Managing hosts.
Procedure
To enable BMC, enter the following command:
# satellite-installer \ --foreman-proxy-bmc "true" \ --foreman-proxy-bmc-default-provider "freeipmi"
3.5. Configuring DNS, DHCP, and TFTP
You can manage DNS, DHCP, and TFTP centrally within the Satellite environment, or you can manage them independently after disabling their maintenance on Satellite. You can also run DNS, DHCP, and TFTP externally, outside of the Satellite environment.
3.5.1. Configuring DNS, DHCP, and TFTP on Satellite Server
To configure the DNS, DHCP, and TFTP services on Satellite Server, use the satellite-installer
command with the options appropriate for your environment.
Any changes to the settings require entering the satellite-installer
command again. You can enter the command multiple times and each time it updates all configuration files with the changed values.
Prerequisites
Ensure that the following information is available to you:
- DHCP IP address ranges
- DHCP gateway IP address
- DHCP nameserver IP address
- DNS information
- TFTP server name
- Use the FQDN instead of the IP address where possible in case of network changes.
- Contact your network administrator to ensure that you have the correct settings.
Procedure
Enter the
satellite-installer
command with the options appropriate for your environment. The following example shows configuring full provisioning services:# satellite-installer \ --foreman-proxy-dns true \ --foreman-proxy-dns-managed true \ --foreman-proxy-dns-zone example.com \ --foreman-proxy-dns-reverse 2.0.192.in-addr.arpa \ --foreman-proxy-dhcp true \ --foreman-proxy-dhcp-managed true \ --foreman-proxy-dhcp-range "192.0.2.100 192.0.2.150" \ --foreman-proxy-dhcp-gateway 192.0.2.1 \ --foreman-proxy-dhcp-nameservers 192.0.2.2 \ --foreman-proxy-tftp true \ --foreman-proxy-tftp-managed true \ --foreman-proxy-tftp-servername 192.0.2.3
You can monitor the progress of the satellite-installer
command displayed in your prompt. You can view the logs in /var/log/foreman-installer/satellite.log
.

For more information about the
satellite-installer
command, entersatellite-installer --help
.
3.5.2. Disabling DNS, DHCP, and TFTP for unmanaged networks
If you want to manage TFTP, DHCP, and DNS services manually, you must prevent Satellite from maintaining these services on the operating system and disable orchestration to avoid DHCP and DNS validation errors. However, Satellite does not remove the back-end services on the operating system.
Procedure
On Satellite Server, enter the following command:
# satellite-installer --foreman-proxy-dhcp false \ --foreman-proxy-dns false \ --foreman-proxy-tftp false
- In the Satellite web UI, navigate to Infrastructure > Subnets and select a subnet.
- Click the Capsules tab and clear the DHCP Capsule, TFTP Capsule, and Reverse DNS Capsule fields.
- In the Satellite web UI, navigate to Infrastructure > Domains and select a domain.
- Clear the DNS Capsule field.
Optional: If you use a DHCP service supplied by a third party, configure your DHCP server to pass the following options:
Option 66: IP address of Satellite or Capsule Option 67: /pxelinux.0
For more information about DHCP options, see RFC 2132.
Satellite does not perform orchestration when a Capsule is not set for a given subnet and domain. When enabling or disabling Capsule associations, orchestration commands for existing hosts can fail if the expected records and configuration files are not present. When associating a Capsule to turn orchestration on, ensure the required DHCP and DNS records as well as the TFTP files are in place for the existing Satellite hosts in order to prevent host deletion failures in the future.
3.5.3. Additional resources
- For more information about configuring DNS, DHCP, and TFTP externally, see Chapter 4, Configuring Satellite Server with external services.
- For more information about configuring DHCP, DNS, and TFTP services, see Configuring Network Services in Provisioning hosts.
3.6. Configuring Satellite Server for outgoing emails
To send email messages from Satellite Server, you can use either an SMTP server, or the sendmail
command.
Prerequisites
-
Some SMTP servers with anti-spam protection or grey-listing features are known to cause problems. To setup outgoing email with such a service either install and configure a vanilla SMTP service on Satellite Server for relay or use the
sendmail
command instead.
Procedure
- In the Satellite web UI, navigate to Administer > Settings.
Click the Email tab and set the configuration options to match your preferred delivery method. The changes have an immediate effect.
The following example shows the configuration options for using an SMTP server:
Table 3.1. Using an SMTP server as a delivery method Name Example value Delivery method
SMTP
SMTP address
smtp.example.com
SMTP authentication

The
SMTP username
andSMTP password
specify the login credentials for the SMTP server.The following example uses gmail.com as an SMTP server:
Table 3.2. Using gmail.com as an SMTP server Name Example value Delivery method

The following example uses the
sendmail
command as a delivery method:Table 3.3. Using sendmail as a delivery method Name Example value Delivery method
Sendmail
Sendmail location
/usr/sbin/sendmail
Sendmail arguments
-i
For security reasons, both Sendmail location and Sendmail argument settings are read-only and can be only set in
/etc/foreman/settings.yaml
. Both settings currently cannot be set viasatellite-installer
. For more information see the sendmail 1 man page.
If you decide to send email using an SMTP server which uses TLS authentication, also perform one of the following steps:
Mark the CA certificate of the SMTP server as trusted. To do so, execute the following commands on Satellite Server:
# cp mailca.crt /etc/pki/ca-trust/source/anchors/ # update-ca-trust enable # update-ca-trust
Where
mailca.crt
is the CA certificate of the SMTP server.-
Alternatively, in the Satellite web UI, set the
SMTP enable StartTLS auto
option toNo
.
-
Click Test email to send a test message to the user’s email address to confirm the configuration is working. If a message fails to send, the Satellite web UI displays an error. See the log at
/var/log/foreman/production.log
for further details.
Additional resources
- For information on configuring email notifications for individual users or user groups, see Configuring Email Notification Preferences in Administering Red Hat Satellite.
3.7. Configuring Satellite Server with a custom SSL certificate
By default, Red Hat Satellite uses a self-signed SSL certificate to enable encrypted communications between Satellite Server, external Capsule Servers, and all hosts. If you cannot use a Satellite self-signed certificate, you can configure Satellite Server to use an SSL certificate signed by an external certificate authority (CA).
When you configure Red Hat Satellite with custom SSL certificates, you must fulfill the following requirements:
- You must use the privacy-enhanced mail (PEM) encoding for the SSL certificates.
- You must not use the same SSL certificate for both Satellite Server and Capsule Server.
- The same CA must sign certificates for Satellite Server and Capsule Server.
- An SSL certificate must not also be a CA certificate.
- An SSL certificate must include a subject alt name (SAN) entry that matches the common name (CN).
- An SSL certificate must be allowed for Key Encipherment using a Key Usage extension.
- An SSL certificate must not have a shortname as the CN.
- You must not set a passphrase for the private key.
To configure your Satellite Server with a custom certificate, complete the following procedures:
- Section 3.7.1, “Creating a custom SSL certificate for Satellite Server”
- Section 3.7.2, “Deploying a custom SSL certificate to Satellite Server”
- Section 3.7.3, “Deploying a custom SSL certificate to hosts”
- If you have external Capsule Servers registered to Satellite Server, configure them with custom SSL certificates. For more information, see Configuring Capsule Server with a Custom SSL Certificate in Installing Capsule Server.
3.7.1. Creating a custom SSL certificate for Satellite Server
Use this procedure to create a custom SSL certificate for Satellite Server. If you already have a custom SSL certificate for Satellite Server, skip this procedure.
Procedure
To store all the source certificate files, create a directory that is accessible only to the
root
user:# mkdir /root/satellite_cert
Create a private key with which to sign the certificate signing request (CSR).
Note that the private key must be unencrypted. If you use a password-protected private key, remove the private key password.
If you already have a private key for this Satellite Server, skip this step.
# openssl genrsa -out
/root/satellite_cert/satellite_cert_key.pem
4096Create the
/root/satellite_cert/openssl.cnf
configuration file for the CSR and include the following content:[ req ] req_extensions = v3_req distinguished_name = req_distinguished_name prompt = no [ req_distinguished_name ] commonName = satellite.example.com [ v3_req ] basicConstraints = CA:FALSE keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment extendedKeyUsage = serverAuth, clientAuth, codeSigning, emailProtection subjectAltName = @alt_names [ alt_names ] DNS.1 = satellite.example.com
Optional: If you want to add Distinguished Name (DN) details to the CSR, add the following information to the
[ req_distinguished_name ]
section:[req_distinguished_name] CN = satellite.example.com countryName =My_Country_Name 1 stateOrProvinceName = My_State_Or_Province_Name 2 localityName = My_Locality_Name 3 organizationName = My_Organization_Or_Company_Name organizationalUnitName = My_Organizational_Unit_Name 4
Generate CSR:
# openssl req -new \ -key /root/satellite_cert/satellite_cert_key.pem \ 1 -config /root/satellite_cert/openssl.cnf \ 2 -out /root/satellite_cert/satellite_cert_csr.pem 3
Send the certificate signing request to the certificate authority (CA). The same CA must sign certificates for Satellite Server and Capsule Server.
When you submit the request, specify the lifespan of the certificate. The method for sending the certificate request varies, so consult the CA for the preferred method. In response to the request, you can expect to receive a CA bundle and a signed certificate, in separate files.
3.7.2. Deploying a custom SSL certificate to Satellite Server
Use this procedure to configure your Satellite Server to use a custom SSL certificate signed by a Certificate Authority. The katello-certs-check
command validates the input certificate files and returns the commands necessary to deploy a custom SSL certificate to Satellite Server.
Do not store the SSL certificates or .tar bundles in /tmp
or /var/tmp
directory. The operating system removes files from these directories periodically. As a result, satellite-installer
fails to execute while enabling features or upgrading Satellite Server.
Procedure
Validate the custom SSL certificate input files. Note that for the
katello-certs-check
command to work correctly, Common Name (CN) in the certificate must match the FQDN of Satellite Server.# katello-certs-check \ -c /root/satellite_cert/satellite_cert.pem \ 1 -k /root/satellite_cert/satellite_cert_key.pem \ 2 -b /root/satellite_cert/ca_cert_bundle.pem 3
If the command is successful, it returns two
satellite-installer
commands, one of which you must use to deploy a certificate to Satellite Server.Example output of
katello-certs-check
Validation succeeded. To install the Red Hat Satellite Server with the custom certificates, run: satellite-installer --scenario satellite \ --certs-server-cert "/root/satellite_cert/satellite_cert.pem" \ --certs-server-key "/root/satellite_cert/satellite_cert_key.pem" \ --certs-server-ca-cert "/root/satellite_cert/ca_cert_bundle.pem" To update the certificates on a currently running Red Hat Satellite installation, run: satellite-installer --scenario satellite \ --certs-server-cert "/root/satellite_cert/satellite_cert.pem" \ --certs-server-key "/root/satellite_cert/satellite_cert_key.pem" \ --certs-server-ca-cert "/root/satellite_cert/ca_cert_bundle.pem" \ --certs-update-server --certs-update-server-ca
Note that you must not access or modify
/root/ssl-build
.From the output of the
katello-certs-check
command, depending on your requirements, enter thesatellite-installer
command that installs a new Satellite with custom SSL certificates or updates certificates on a currently running Satellite.If you are unsure which command to run, you can verify that Satellite is installed by checking if the file
/etc/foreman-installer/scenarios.d/.installed
exists. If the file exists, run the secondsatellite-installer
command that updates certificates.Importantsatellite-installer
needs the certificate archive file after you deploy the certificate. Do not modify or delete it. It is required, for example, when upgrading Satellite Server.-
On a computer with network access to Satellite Server, navigate to the following URL:
https://satellite.example.com
. - In your browser, view the certificate details to verify the deployed certificate.
3.7.3. Deploying a custom SSL certificate to hosts
After you configure Satellite to use a custom SSL certificate, you must deploy the certificate to hosts registered to Satellite.
Procedure
Update the SSL certificate on each host:
# dnf install http://satellite.example.com/pub/katello-ca-consumer-latest.noarch.rpm
3.8. Using external databases with Satellite
As part of the installation process for Red Hat Satellite, the satellite-installer command installs PostgreSQL databases on the same server as Satellite. In certain Satellite deployments, using external databases instead of the default local databases can help with the server load.
Red Hat does not provide support or tools for external database maintenance. This includes backups, upgrades, and database tuning. You must have your own database administrator to support and maintain external databases.
To create and use external databases for Satellite, you must complete the following procedures:
- Section 3.8.2, “Preparing a host for external databases”. Prepare a host for the external databases.
- Section 3.8.3, “Installing PostgreSQL”. Prepare PostgreSQL with databases for Satellite, Candlepin and Pulp with dedicated users owning them.
-
Section 3.8.4, “Configuring Satellite Server to use external databases”. Edit the parameters of
satellite-installer
to point to the new databases, and runsatellite-installer
.
3.8.1. PostgreSQL as an external database considerations
Foreman, Katello, and Candlepin use the PostgreSQL database. If you want to use PostgreSQL as an external database, the following information can help you decide if this option is right for your Satellite configuration. Satellite supports PostgreSQL version 13.
Advantages of external PostgreSQL
- Increase in free memory and free CPU on Satellite
-
Flexibility to set
shared_buffers
on the PostgreSQL database to a high number without the risk of interfering with other services on Satellite - Flexibility to tune the PostgreSQL server’s system without adversely affecting Satellite operations
Disadvantages of external PostgreSQL
- Increase in deployment complexity that can make troubleshooting more difficult
- The external PostgreSQL server is an additional system to patch and maintain
- If either Satellite or the PostgreSQL database server suffers a hardware or storage failure, Satellite is not operational
- If there is latency between the Satellite server and database server, performance can suffer
If you suspect that the PostgreSQL database on your Satellite is causing performance problems, use the information in Satellite 6: How to enable postgres query logging to detect slow running queries to determine if you have slow queries. Queries that take longer than one second are typically caused by performance issues with large installations, and moving to an external database might not help. If you have slow queries, contact Red Hat Support.
3.8.2. Preparing a host for external databases
Install a freshly provisioned system with the latest Red Hat Enterprise Linux 9 or Red Hat Enterprise Linux 8 to host the external databases.
Subscriptions for Red Hat Enterprise Linux do not provide the correct service level agreement for using Satellite with external databases. You must also attach a Satellite subscription to the base operating system that you want to use for the external databases.
Prerequisites
- The prepared host must meet Satellite’s Storage Requirements.
- You must attach a Satellite subscription to your server. For more information about subscription, see Attaching the Satellite Infrastructure Subscription in Installing Satellite Server in a connected network environment.
Procedure
Select the operating system and version you are installing external database on:
3.8.2.1. Red Hat Enterprise Linux 9
Disable all repositories:
# subscription-manager repos --disable "*"
Enable the following repositories:
# subscription-manager repos \ --enable=satellite-6.16-for-rhel-9-x86_64-rpms \ --enable=satellite-maintenance-6.16-for-rhel-9-x86_64-rpms \ --enable=rhel-9-for-x86_64-baseos-rpms \ --enable=rhel-9-for-x86_64-appstream-rpms
Verification
Verify that the required repositories are enabled:
# dnf repolist enabled
3.8.2.2. Red Hat Enterprise Linux 8
Disable all repositories:
# subscription-manager repos --disable "*"
Enable the following repositories:
# subscription-manager repos \ --enable=satellite-6.16-for-rhel-8-x86_64-rpms \ --enable=satellite-maintenance-6.16-for-rhel-8-x86_64-rpms \ --enable=rhel-8-for-x86_64-baseos-rpms \ --enable=rhel-8-for-x86_64-appstream-rpms
Enable the following module:
# dnf module enable satellite:el8
NoteEnablement of the module
satellite:el8
warns about a conflict withpostgresql:10
andruby:2.5
as these modules are set to the default module versions on Red Hat Enterprise Linux 8. The modulesatellite:el8
has a dependency for the modulespostgresql:12
andruby:2.7
that will be enabled with thesatellite:el8
module. These warnings do not cause installation process failure, hence can be ignored safely. For more information about modules and lifecycle streams on Red Hat Enterprise Linux 8, see Red Hat Enterprise Linux Application Streams Lifecycle.
Verification
Verify that the required repositories are enabled:
# dnf repolist enabled
3.8.3. Installing PostgreSQL
You can install only the same version of PostgreSQL that is installed with the satellite-installer
tool during an internal database installation. Satellite supports PostgreSQL version 12.
Procedure
To install PostgreSQL, enter the following command:
# dnf install postgresql-server postgresql-evr postgresql-contrib
To initialize PostgreSQL, enter the following command:
# postgresql-setup initdb
Edit the
/var/lib/pgsql/data/postgresql.conf
file:# vi /var/lib/pgsql/data/postgresql.conf
Note that the default configuration of external PostgreSQL needs to be adjusted to work with Satellite. The base recommended external database configuration adjustments are as follows:
- checkpoint_completion_target: 0.9
- max_connections: 500
- shared_buffers: 512MB
- work_mem: 4MB
Remove the
#
and edit to listen to inbound connections:listen_addresses = '*'
Add the following line to the end of the file to use SCRAM for authentication:
password_encryption=scram-sha-256
Edit the
/var/lib/pgsql/data/pg_hba.conf
file:# vi /var/lib/pgsql/data/pg_hba.conf
Add the following line to the file:
host all all Satellite_ip/32 scram-sha-256
To start, and enable PostgreSQL service, enter the following commands:
# systemctl enable --now postgresql
Open the postgresql port on the external PostgreSQL server:
# firewall-cmd --add-service=postgresql
Make the changes persistent:
# firewall-cmd --runtime-to-permanent
Switch to the
postgres
user and start the PostgreSQL client:$ su - postgres -c psql
Create three databases and dedicated roles: one for Satellite, one for Candlepin, and one for Pulp:
CREATE USER "foreman" WITH PASSWORD 'Foreman_Password'; CREATE USER "candlepin" WITH PASSWORD 'Candlepin_Password'; CREATE USER "pulp" WITH PASSWORD 'Pulpcore_Password'; CREATE DATABASE foreman OWNER foreman; CREATE DATABASE candlepin OWNER candlepin; CREATE DATABASE pulpcore OWNER pulp;
Connect to the Pulp database:
postgres=# \c pulpcore You are now connected to database "pulpcore" as user "postgres".
Create the
hstore
extension:pulpcore=# CREATE EXTENSION IF NOT EXISTS "hstore"; CREATE EXTENSION
Exit the
postgres
user:# \q
From Satellite Server, test that you can access the database. If the connection succeeds, the commands return
1
.# PGPASSWORD='Foreman_Password' psql -h postgres.example.com -p 5432 -U foreman -d foreman -c "SELECT 1 as ping" # PGPASSWORD='Candlepin_Password' psql -h postgres.example.com -p 5432 -U candlepin -d candlepin -c "SELECT 1 as ping" # PGPASSWORD='Pulpcore_Password' psql -h postgres.example.com -p 5432 -U pulp -d pulpcore -c "SELECT 1 as ping"
3.8.4. Configuring Satellite Server to use external databases
Use the satellite-installer
command to configure Satellite to connect to an external PostgreSQL database.
Prerequisites
- You have installed and configured a PostgreSQL database on a Red Hat Enterprise Linux server.
Procedure
To configure the external databases for Satellite, enter the following command:
