24.6. Setting the parameters for a deployment with external DNS and an integrated CA as the root CA

Procedure

1. Create a ~/MyPlaybooks/ directory:

   $ mkdir MyPlaybooks

2. Create a ~/MyPlaybooks/inventory file.

3. Open the inventory file for editing. Specify the fully-qualified domain names (FQDN) of the host you want to use as an IdM server. Ensure that the FQDN meets the following criteria:

   • Only alphanumeric characters and hyphens (-) are allowed. For example, underscores are not allowed and can cause DNS failures.
   • The host name must be all lower-case.
4. Specify the IdM domain and realm information.
5. Make sure that the ipaserver_setup_dns option is set to no or that it is absent.
6. Specify the passwords for admin and for the Directory Manager. Use the Ansible Vault to store the password, and reference the Vault file from the playbook file. Alternatively and less securely, specify the passwords directly in the inventory file.

7. Optional: Specify a custom firewalld zone to be used by the IdM server. If you do not set a custom zone, IdM will add its services to the default firewalld zone. The predefined default zone is public.

   중요

   The specified firewalld zone must exist and be permanent.

   Example of an inventory file with the required server information (excluding the passwords)

   [ipaserver]
   server.idm.example.com
   
   [ipaserver:vars]
   ipaserver_domain=idm.example.com
   ipaserver_realm=IDM.EXAMPLE.COM
   ipaserver_setup_dns=no
   [...]

   Example of an inventory file with the required server information (including the passwords)

   [ipaserver]
   server.idm.example.com
   
   [ipaserver:vars]
   ipaserver_domain=idm.example.com
   ipaserver_realm=IDM.EXAMPLE.COM
   ipaserver_setup_dns=no
   ipaadmin_password=MySecretPassword123
   ipadm_password=MySecretPassword234
   
   [...]

   Example of an inventory file with a custom firewalld zone

   [ipaserver]
   server.idm.example.com
   
   [ipaserver:vars]
   ipaserver_domain=idm.example.com
   ipaserver_realm=IDM.EXAMPLE.COM
   ipaserver_setup_dns=no
   ipaadmin_password=MySecretPassword123
   ipadm_password=MySecretPassword234
   ipaserver_firewalld_zone=custom zone
