Chapter 3. Performing Additional Configuration on Satellite Server

To Install the Satellite Tools Repository Using the Web UI:

1. In the Satellite web UI, navigate to Content > Red Hat Repositories.
2. Use the Search field to enter the following repository name: Red Hat Satellite Tools 6.4 (for RHEL 7 Server) (RPMs).

3. In the Available Repositories pane, click on Red Hat Satellite Tools 6.4 (for RHEL 7 Server) (RPMs) to expand the repository set.

   If the Red Hat Satellite Tools 6.4 items are not visible, it may be because they are not included in the Subscription Manifest obtained from the Customer Portal. To correct that, log in to the Customer Portal, add these repositories, download the Subscription Manifest and import it into Satellite.

4. For the x86_64 entry, click the Enable icon to enable the repository.

To Synchronize the Satellite Tools Repository Using the Web UI:

1. Navigate to Content > Sync Status.

   A list of product repositories available for synchronization is displayed.

2. Click the arrow next to the product content to view available content.
3. Select the content you want to synchronize.
4. Click Synchronize Now.

Enable Power Management on Managed Hosts

1. Run the installer with the options to enable BMC.

Configure DNS, DHCP, and TFTP on Satellite Server

1. Run satellite-installer with the options appropriate for your environment.

   # satellite-installer --scenario satellite \
   --foreman-proxy-dns true \
   --foreman-proxy-dns-managed true \
   --foreman-proxy-dns-interface eth0 \
   --foreman-proxy-dns-zone example.com \
   --foreman-proxy-dns-forwarders 172.17.13.1 \
   --foreman-proxy-dns-reverse 13.17.172.in-addr.arpa \
   --foreman-proxy-dhcp true \
   --foreman-proxy-dhcp-managed true \
   --foreman-proxy-dhcp-interface eth0 \
   --foreman-proxy-dhcp-range "172.17.13.100 172.17.13.150" \
   --foreman-proxy-dhcp-gateway 172.17.13.1 \
   --foreman-proxy-dhcp-nameservers 172.17.13.2 \
   --foreman-proxy-tftp true \
   --foreman-proxy-tftp-managed true \
   --foreman-proxy-tftp-servername $(hostname)

   For more information about configuring DHCP, DNS, and TFTP services, see the Configuring Network Services section in the Provisioning Guide.

   The script displays its progress and writes logs to /var/log/foreman-installer/satellite.log. You can view the settings used, including the admin_password parameter, in the /etc/foreman-installer/scenarios.d/satellite-answers.yaml file.

1. On Satellite Server, enter the following command:

   # satellite-installer --foreman-proxy-dhcp false \
   --foreman-proxy-dns false \
   --foreman-proxy-tftp false

2. In the Satellite web UI, navigate to Infrastructure > Subnets and select a subnet.
3. Click the Capsules tab and clear the DHCP Capsule, TFTP Capsule, and Reverse DNS Capsule fields.
4. Navigate to Infrastructure > Domains and select a domain.
5. Clear the DNS Capsule field.

6. 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.

To Configure Satellite Server for Outgoing Emails:

1. In the Satellite web UI, navigate to Administer Settings.

2. Click the Email tab and set the configuration options to match your preferred delivery method. The changes have an immediate effect.

   1. The following example shows the configuration options for using an SMTP server:

      Expand

      Table 3.1. Using an SMTP server as a delivery method

      Name	Example value
      Delivery method	SMTP
      SMTP address	smtp.example.com
      SMTP authentication	login
      SMTP HELO/EHLO domain	example.com
      SMTP password	password
      SMTP port	25
      SMTP username	satellite@example.com

      Show more

      The SMTP username and SMTP password specify the login credentials for the SMTP server.

   2. The following example uses gmail.com as an SMTP server:

      Expand

      Table 3.2. Using gmail.com as an SMTP server

      Name	Example value
      Delivery method	SMTP
      SMTP address	smtp.gmail.com
      SMTP authentication	plain
      SMTP HELO/EHLO domain	smtp.gmail.com
      SMTP enable StartTLS auto	Yes
      SMTP password	password
      SMTP port	587
      SMTP username	user@gmail.com

      Show more

   3. The following example uses the sendmail command as a delivery method:

      Expand

      Table 3.3. Using sendmail as a delivery method

      Name	Example value
      Delivery method	Sendmail
      Sendmail arguments	-i -t -G

      Show more

      The Sendmail arguments specify the options passed to the sendmail command. The default value is -i -t. For more information see the sendmail 1 man page.

3. 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

     Copy to Clipboard Toggle word wrap

     Where mailca.crt is the CA certificate of the SMTP server.

   • Alternatively, in the web UI, set the SMTP enable StartTLS auto option to No.
4. 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 web UI displays an error. See the log at /var/log/foreman/production.log for further details.

1. Section 3.6.1, “Obtain an SSL Certificate for Satellite Server”
2. Section 3.6.2, “Validate the Satellite Server’s SSL Certificate”
3. Section 3.6.3, “Run the Satellite Installer with Custom Certificate Parameters”
4. Section 3.6.4, “Install the New Certificate on all Hosts Connected to the Satellite Server”
5. If you have external Capsule Servers registered to the Satellite Server, proceed to Configuring Capsule Server with a Custom Server Certificate in the Installing Capsule Server guide to configure the Capsule Servers to use a custom certificate.
