In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Haz clic en el siguiente botón para abrir Cloud Shell, que proporciona
acceso de línea de comandos a tus recursos de Google Cloud directamente desde el navegador.
Cloud Shell se puede usar para ejecutar los comandos de gcloud que se presentan en esta guía de inicio rápido.
Ejecuta el comando gcloud services enable de la siguiente manera con Cloud Shell a fin de habilitar las API necesarias para esta guía de inicio rápido:
gcloudservicesenablesqladmin.googleapis.com
Este comando habilita las siguientes API:
API de Cloud SQL Admin
Make sure that you have the following role or roles on the project:
Cloud SQL Admin (roles/cloudsql.admin), Cloud SQL Viewer (roles/cloudsql.viewer)
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.
En el campo Principales nuevas, ingresa tu identificador de usuario.
Esta suele ser la dirección de correo electrónico de una Cuenta de Google.
En la lista Seleccionar un rol, elige uno.
Para otorgar roles adicionales, haz clic en addAgregar
otro rol y agrega uno más.
Haz clic en Guardar.
Cree una instancia de Cloud SQL
En esta guía de inicio rápido, usarás la Google Cloud consola. Para usar
gcloud CLI, cURL o PowerShell, consulta la documentación sobre
cómo crear instancias.
En la Google Cloud consola, ve a la página Instancias de Cloud SQL.
En el campo Contraseña, ingresa una contraseña para el usuario sqlserver.
Haz clic en Crear instancia.
Volverás a la lista de las instancias. Puedes hacer clic en la instancia nueva de inmediato para ver los detalles, pero no estará disponible para otras operaciones hasta que se inicialice y se inicie.
Debian/Ubuntu
En Debian/Ubuntu, instala las herramientas de línea de comandos de SQL Server aplicables mediante estas instrucciones.
CentOS/RHEL
Para CentOS/RHEL, instala las herramientas de línea de comandos de SQL Server aplicables mediante estas instrucciones.
openSUSE
Para openSUSE, instala las herramientas de línea de comandos de SQL Server aplicables mediante estas instrucciones.
Haz clic en el nombre de la instancia para abrir la página Descripción general de esa instancia.
En la sección Conéctate a esta instancia, copia el Nombre de la conexión. El nombre de la conexión tiene el formato projectID:region:instanceID.
Inicia el proxy de Cloud SQL Auth
Inicia el proxy de Cloud SQL Auth en su propia terminal para poder supervisar el resultado. Reemplaza INSTANCE_CONNECTION_NAME por el nombre de la conexión de instancia que copiaste en el paso anterior.
En entornos de Linux, usa este comando para iniciar el proxy de Cloud SQL Auth:
./cloud-sql-proxyINSTANCE_CONNECTION_NAME
En PowerShell de Windows, usa este comando para iniciar el proxy de Cloud SQL Auth:
.\cloud-sql-proxy.exeINSTANCE_CONNECTION_NAME
Aparecerá un mensaje similar al que figura a continuación:
Listening on 127.0.0.1:1433 for INSTANCE_CONNECTION_NAME
Ready for new connections
Ejecuta el siguiente comando y reemplaza USER_NAME por tu nombre de usuario de SQL Server.
sqlcmd-S127.0.0.1-UUSER_NAME
Regresa a la ventana de terminal en la que iniciaste el proxy de Cloud SQL Auth. Deberías ver un mensaje similar al siguiente:
New connection for myInstance
Limpia
