Chapter 16. Uninstalling Certificate System subsystems

Removing a subsystem requires specifying the subsystem type and the name of the server in which the subsystem is running. This command removes all files associated with the subsystem (without removing the subsystem packages).

pkidestroy -s subsystem_type -i instance_name

# pkidestroy -s subsystem_type -i instance_name

The -s option specifies the subsystem to be removed (such as CA, KRA, OCSP, TKS, or TPS). The -i option specifies the instance name, such as pki-tomcat.

For example, to remove a CA subsystem:

pkidestroy -s CA -i pki-tomcat

# pkidestroy -s CA -i pki-tomcat

Loading deployment configuration from /var/lib/pki/pki-tomcat/ca/registry/ca/deployment.cfg.
Uninstalling CA from /var/lib/pki/pki-tomcat.
Removed symlink /etc/systemd/system/multi-user.target.wants/pki-tomcatd.target.

Uninstallation complete.

The pkidestroy utility removes the subsystem and any related files, such as the certificate databases, certificates, keys, and associated users. It does not uninstall the subsystem packages. If the subsystem is the last subsystem on the server instance, the server instance is removed as well.

A number of subsystem-related packages and dependencies are installed with Red Hat Certificate System; these are listed in Section 6.9, “Installing RHCS and RHDS packages”. Removing a subsystem removes only the files and directories associated with that specific subsystem. It does not remove the actual installed packages that are used by that instance. Completely uninstalling Red Hat Certificate System or one of its subsystems requires using package management tools, like yum, to remove each package individually.

To uninstall an individual Certificate System subsystem package:
