红帽全球峰会第 19 章 Renaming IdM client systems
You can change the host name of an Identity Management (IdM) client system.
Renaming a client is a manual procedure. Do not perform it unless changing the host name is absolutely required.
Renaming an Identity Management client involves:
- Preparing the host. For details, see Preparing an IdM client for its renaming.
- Uninstalling the IdM client from the host. For details, see Uninstalling an Identity Management client.
- Renaming the host. For details, see Renaming the host system.
- Installing the IdM client on the host with the new name. For details, see Installing an Identity Management client in Installing Identity Management.
- Configuring the host after the IdM client installation. For details, see Re-adding services, re-generating certificates, and re-adding host groups.
19.1. Preparing an IdM client for its renaming
Before uninstalling the current client, make note of certain settings for the client. You will apply this configuration after re-enrolling the machine with a new host name.
Identify which services are running on the machine:
Use the
ipa service-findcommand, and identify services with certificates in the output:$ ipa service-find old-client-name.example.com-
In addition, each host has a default host service which does not appear in the
ipa service-findoutput. The service principal for the host service, also called a host principal, ishost/old-client-name.example.com.
For all service principals displayed by
ipa service-find old-client-name.example.com, determine the location of the corresponding keytabs on theold-client-name.example.comsystem:# find / -name "*.keytab"Each service on the client system has a Kerberos principal in the form service_name/host_name@REALM, such as
ldap/old-client-name.example.com@EXAMPLE.COM.Identify all host groups to which the machine belongs.
# ipa hostgroup-find old-client-name.example.com
