AlloyDB Omni hat eine Standardkonfigurationsdatei mit dem Namen dataplane.conf, die sich im Verzeichnis /var/alloydb/config befindet.
Wenn Sie den Speicherort des Datenverzeichnisses Ihres Servers ändern möchten, aktualisieren Sie die Variable DATADIR_PATH in der Datei dataplane.conf.
Führen Sie den folgenden Befehl aus, um die Variable DATADIR_PATH in dataplane.conf zu aktualisieren:
Ersetzen Sie DATA_DIRECTORY durch den vollständigen Dateisystempfad zum vorhandenen Verzeichnis, in dem sich Ihre AlloyDB Omni-Installation befinden soll.
Alternativ können Sie dataplane.conf in einem Texteditor öffnen und den Wert der DATADIR_PATH-Anweisung aktualisieren.
Andere Serveroptionen konfigurieren
Das Verzeichnis /var/alloydb/config enthält auch die folgenden zwei Standard-PostgreSQL-Konfigurationsdateien:
Das AlloyDB Omni-Installationsprogramm füllt beide Dateien mit Standardwerten, damit Sie direkt loslegen können. Sie können beide Dateien nach Bedarf aktualisieren.
Kubernetes
Sie konfigurieren und steuern einen Kubernetes-basierten AlloyDB Omni-Datenbankcluster, indem Sie deklarative Manifestdateien mit dem kubectl-Dienstprogramm kombinieren, genau wie bei jeder anderen Kubernetes-basierten Bereitstellung.

You can update both files in whatever\nway is appropriate for your own needs.\n| **Caution:** AlloyDB Omni copies these files into your data directory for its own runtime use. Edit only the files in `/var/alloydb/config`, and not the copies in your data directory. Otherwise, any changes you make to those files risk being overwritten.\n\n### Kubernetes\n\nYou configure and control a Kubernetes-based AlloyDB Omni database\ncluster by pairing declarative manifest files with the `kubectl` utility, just\nlike any other Kubernetes-based deployment.\n\nSome resources that you can configure are:\n\n- [Manage backup and restore](/alloydb/omni/15.5.2/docs/backup-kubernetes)\n- [Create read pool instance in Kubernetes](/alloydb/omni/15.5.2/docs/kubernetes-read-pool)\n- [Use a sidecar container in Kubernetes](/alloydb/omni/15.5.2/docs/kubernetes-sidecar-container)\n\nWhat's next\n-----------\n\n- [Run and connect to AlloyDB Omni](/alloydb/omni/15.5.2/docs/run-connect)\n\n- [Manage AlloyDB Omni](/alloydb/omni/15.5.2/docs/manage)\n\n- [Create a read-only replica](/alloydb/omni/15.5.2/docs/set-up-read-replica)"]]
