This page contains information about creating, listing, and deleting MySQLdatabases on a Cloud SQL instance.
A newly-created instance has four system databases:
information_schema
: Provides access to database metadata, information about the MySQL server.mysql
: The system schema. It contains tables that store information required by the MySQL server as it runs.performance_schema
: A feature for monitoring MySQL Server execution at a low level.sys
: Contains a set of objects that helps DBAs and developers interpret data collected by the performance schema.
Before you begin
Before completing the tasks on this page, you must have:
- Created a Cloud SQL instance. For more information,seeCreating instances.
If you plan to use the mysql client to create or manage your databases,you must have:
- Configured access and connected to the instance with a
mysql
client.For more information about connection options, seeConnection Options for External Applications.
Create a database on the Cloud SQL instance
Note:The maximum length of the database name is 64 characters. For more information on other criteria for this name, seeSchema Object Names.
If you don't specify a custom character set and collation when you create your database, then the database has the following default values:
- MySQL 5.6, 5.7: (created with Google Cloud console, Cloud SQL Admin API,gcloud CLI, Terraform, or mysql client)
- Character set:
utf8
- Collation:
utf8_general_ci
- MySQL 8.0.x and later (created with the Google Cloud console)
- Character set:
utf8
- Collation:
utf8_general_ci
- MySQL 8.0.x and later (created with the Cloud SQL Admin API,gcloud CLI, Terraform, or mysql client)
- Character set:
utf8mb4
- Collation:
utf8mb4_0900_ai_ci
If you need to modify the character set or collation configuration of your database after creation, then seeUpdate the character set and collation for a database.
Console
In the Google Cloud console, go to theCloud SQL Instances page.
- To open theOverview page of an instance, click the instance name.
- SelectDatabases from the SQL navigation menu.
- ClickCreate database.
- In theCreate a database dialog, specify the name of the database, and optionally the character set and collation.
For more information about character sets and collations, seeCharacter Sets, Collations, Unicode.
- ClickCreate.
gcloud
For reference information, seegcloud sql databases create
.
For more information about character sets and collations, seeCharacter Sets, Collations, Unicode.
gcloudsqldatabasescreateDATABASE_NAME\--instance=INSTANCE_NAME\[--charset=CHARSET]\[--collation=COLLATION]
Terraform
To create a database, use aTerraform resource.
resource "google_sql_database" "database" { name = "my-database" instance = google_sql_database_instance.instance.name}
Apply the changes
To apply your Terraform configuration in a Google Cloud project, complete the steps in the following sections.
Prepare Cloud Shell
- LaunchCloud Shell.
Set the default Google Cloud project where you want to apply your Terraform configurations.
You only need to run this command once per project, and you can run it in any directory.
export GOOGLE_CLOUD_PROJECT=PROJECT_ID
Environment variables are overridden if you set explicit values in the Terraform configuration file.
Prepare the directory
Each Terraform configuration file must have its own directory (alsocalled aroot module).
- InCloud Shell, create a directory and a new file within that directory. The filename must have the
.tf
extension—for examplemain.tf
. In this tutorial, the file is referred to asmain.tf
.mkdirDIRECTORY && cdDIRECTORY && touch main.tf
If you are following a tutorial, you can copy the sample code in each section or step.
Copy the sample code into the newly created
main.tf
.Optionally, copy the code from GitHub. This is recommended when the Terraform snippet is part of an end-to-end solution.
- Review and modify the sample parameters to apply to your environment.
- Save your changes.
- Initialize Terraform. You only need to do this once per directory.
terraform init
Optionally, to use the latest Google provider version, include the
-upgrade
option:terraform init -upgrade
Apply the changes
- Review the configuration and verify that the resources that Terraform is going to create or update match your expectations:
terraform plan
Make corrections to the configuration as necessary.
- Apply the Terraform configuration by running the following command and entering
yes
at the prompt:terraform apply
Wait until Terraform displays the "Apply complete!" message.
- Open your Google Cloud project to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.
Delete the changes
To delete your changes, do the following:
- To disable deletion protection, in your Terraform configuration file set the
deletion_protection
argument tofalse
.deletion_protection = "false"
- Apply the updated Terraform configuration by running the following command and entering
yes
at the prompt:terraform apply
Remove resources previously applied with your Terraform configuration by running the following command and entering
yes
at the prompt:terraform destroy
