NAME¶
pki-server-upgrade - Tool for upgrading PKI server configuration.
SYNOPSIS¶
pki-server [CLI-options] upgrade [OPTIONS]
DESCRIPTION¶
There are two parts to upgrading PKI server: upgrading the system configuration files used by both the client and the server processes and upgrading the server configuration files.
When upgrading PKI server, the existing server configuration files (e.g. server.xml, web.xml) may need to be upgraded because the content may have changed from one version to another. The configuration upgrade is executed automatically during RPM upgrade. However, in case there is a problem, the process can also be run manually using pki-server upgrade.
The server upgrade process is done incrementally using upgrade scriptlets. A server consists of the server instance itself and the subsystems running in that instance. The upgrade process executes one scriptlet at a time, running through each component (server instance and subsystem) in parallel and completing before executing the next scriptlet. If one component encounters an error, that component is skipped in the subsequent upgrade scriptlets. The upgrade process and scriptlet execution for each component is monitored in upgrade trackers. A counter shows the latest index number for the most recently executed scriptlet; when all scriptlets have run, the component tracker shows the updated version number.
The scriptlets are stored in the upgrade directory:
/usr/share/pki/server/upgrade/<version>/<index>-<name>
The version is the server version to be upgraded. The index is the script execution order. The name is the scriptlet name.
During upgrade, the scriptlets will back up all changes to the file system into the following folder:
/var/log/pki/server/upgrade/<version>/<index>
The version and index values indicate the scriptlet being executed. A copy of the files and folders that are being modified or removed will be stored in oldfiles. The names of the newly-added files and folders will be stored in newfiles.
The instance upgrade process is tracked using this file:
/var/lib/pki/<instance>/conf/tomcat.conf
The subsystem upgrade process is tracked using this file:
/var/lib/pki/<instance>/<subsystem>/conf/CS.cfg
The file stores the current configuration version and the last successful scriptlet index.
OPTIONS¶
General options¶
--status
Show upgrade status only without performing the upgrade.
--revert
Revert the last version.
-i, --instance instance
Upgrade a specific instance only.
-X
Show advanced options.
-v, --verbose
Run in verbose mode.
-h, --help
Show this help message.
Advanced options¶
The advanced options circumvent the normal upgrade process by changing the tracker information.
WARNING: These options may render the system unusable.
--remove-tracker
Remove the tracker.
--reset-tracker
Reset the tracker to match the package version.
--set-tracker version
Set the tracker to a specific version.
OPERATIONS¶
Upgrade process¶
To start the upgrade process:
$ pki-server upgrade
Upgrade status¶
To check the upgrade status:
$ pki-server upgrade --status
Troubleshooting¶
Check the scriptlet to see which operations are being executed. Once the error is identified and corrected, the upgrade can be resumed by re-running pki-server upgrade.
If necessary, the upgrade can be run in verbose mode:
$ pki-server upgrade --verbose
It is possible to rerun a failed upgrade for a specific instance:
$ pki-server upgrade --instance pki-tomcat
Reverting an upgrade¶
If necessary, the upgrade can be reverted:
$ pki-server upgrade --revert
Files and folders that were created by the scriptlet will be removed. Files and folders that were modified or removed by the scriptlet will be restored.
