2.4. Starting and stopping an individual Identity Management service


Changing IdM configuration files manually is generally not recommended. However, certain situations require that an administrator performs a manual configuration of specific services. In such situations, use the systemctl utility to stop, start, or restart an individual IdM service.

For example, use systemctl after customizing the Directory Server behavior, without modifying the other IdM services:

# systemctl restart dirsrv@REALM-NAME.service

Also, when initially deploying an IdM trust with Active Directory, modify the /etc/sssd/sssd.conf file, adding:

  • Specific parameters to tune the timeout configuration options in an environment where remote servers have a high latency
  • Specific parameters to tune the Active Directory site affinity
  • Overrides for certain configuration options that are not provided by the global IdM settings

To apply the changes you have made in the /etc/sssd/sssd.conf file:

# systemctl restart sssd.service

Running systemctl restart sssd.service is required because the System Security Services Daemon (SSSD) does not automatically re-read or re-apply its configuration.

Note that for changes that affect IdM identity ranges, a complete server reboot is recommended.

重要

To restart multiple IdM domain services, always use systemctl restart ipa. Because of dependencies between the services installed with the IdM server, the order in which they are started and stopped is critical. The ipa systemd service ensures that the services are started and stopped in the appropriate order.

Useful systemctl commands
To start a particular IdM service:
# systemctl start name.service

To stop a particular IdM service:

# systemctl stop name.service

To restart a particular IdM service:

# systemctl restart name.service

To view the status of a particular IdM service:

# systemctl status name.service
重要

You cannot use the IdM web UI to start or stop the individual services running on IdM servers. You can only use the web UI to modify the settings of a Kerberized service by navigating to Identity Services and selecting the service.
