In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Klicken Sie auf die folgende Schaltfläche, um Cloud Shell zu öffnen, die Befehlszeilenzugriff auf Ihre Google Cloud Ressourcen direkt über den Browser bietet.
Mit Cloud Shell können Sie die in dieser Kurzanleitung vorgestellten gcloud-Befehle ausführen.
In the Principal column, find all rows that identify you or a group that
you're included in. To learn which groups you're included in, contact your
administrator.
For all rows that specify or include you, check the Role column to see whether
the list of roles includes the required roles.
Klicken Sie auf person_addZugriffsrechte erteilen.
Geben Sie im Feld Neue Hauptkonten Ihre Nutzer-ID ein.
Das ist in der Regel die E‑Mail-Adresse eines Google-Kontos.
Wählen Sie in der Liste Rolle auswählen eine Rolle aus.
Klicken Sie auf addWeitere Rolle hinzufügen, wenn Sie weitere Rollen zuweisen möchten.
Klicken Sie auf Speichern.
Cloud SQL-Instanz erstellen
In dieser Kurzanleitung verwenden Sie die Google Cloud Console. Informationen zur Verwendung der gcloud CLI, cURL oder PowerShell finden Sie unter Instanzen erstellen.
Wechseln Sie in der Google Cloud Console zur Seite Cloud SQL-Instanzen.
Geben Sie im Feld Instanz-ID den Wert myinstance ein.
Geben Sie im Feld Passwort ein Passwort für den Nutzer sqlserver ein.
Klicken Sie auf Instanz erstellen.
Sie werden zur Instanzliste zurückgeleitet. Sie können direkt auf die neue Instanz klicken, um die Details aufzurufen. Die Instanz steht jedoch erst für andere Vorgänge zur Verfügung, wenn sie initialisiert und gestartet wurde.
Debian/Ubuntu
Installieren Sie für Debian/Ubuntu die entsprechenden SQL Server-Befehlszeilentools mit diesen Anleitungen.
CentOS/RHEL
Installieren Sie für CentOS/RHEL die entsprechenden SQL Server-Befehlszeilentools mit diesen Anleitungen.
openSUSE
Installieren Sie für openSUSE die entsprechenden SQL Server-Befehlszeilentools mit diesen Anleitungen.
Klicken Sie auf den Instanznamen, um die zugehörige Seite Übersicht zu öffnen.
Kopieren Sie im Abschnitt Mit dieser Instanz verbinden den Verbindungsnamen. Der Verbindungsname hat das Format projectID:region:instanceID.
Cloud SQL Auth-Proxy starten
Starten Sie den Cloud SQL Auth-Proxy in einem eigenen Terminal, damit Sie die Ausgabe überwachen können. Ersetzen Sie INSTANCE_CONNECTION_NAME durch den Namen der Instanzverbindung, den Sie im vorherigen Schritt kopiert haben.
Verwenden Sie in Linux-Umgebungen den folgenden Befehl, um den Cloud SQL Auth-Proxy zu starten:
./cloud-sql-proxyINSTANCE_CONNECTION_NAME
Verwenden Sie in PowerShell unter Windows den folgenden Befehl, um den Cloud SQL Auth-Proxy zu starten:
.\cloud-sql-proxy.exeINSTANCE_CONNECTION_NAME
Es wird dann eine Meldung wie die folgende angezeigt:
Listening on 127.0.0.1:1433 for INSTANCE_CONNECTION_NAME
Ready for new connections
Führen Sie den folgenden Befehl aus und ersetzen Sie dabei USER_NAME durch den SQL Server-Nutzernamen.
sqlcmd-S127.0.0.1-UUSER_NAME
Kehren Sie zum Terminalfenster zurück, in dem Sie den Cloud SQL Auth-Proxy gestartet haben. Es wird eine Meldung ähnlich der folgenden angezeigt:
New connection for myInstance
