Connect to Cloud SQL for MySQL using the Cloud SQL Auth Proxy

This page shows you how to connect to Cloud SQL from a local test environment using the Cloud SQL Auth Proxy. The Cloud SQL Auth Proxy provides secure access to your Cloud SQL instance without the need for authorized networks or for configuring SSL. By using the Cloud SQL Auth Proxy, you can connect to your Cloud SQL instance securely.

The instructions on this page are for a test environment only and shouldn't be used for production environments. For more information on the configuration required for production environments, see Use the Cloud SQL Auth Proxy in a production environment and Connect using the Cloud SQL Auth Proxy.

Create a Cloud SQL instance

In this quickstart, you use the Google Cloud console. To use the gcloud CLI, cURL, or PowerShell, see Create instances.

  1. In the Google Cloud console, go to the Cloud SQL Instances page.

    Go to Cloud SQL Instances

  2. Click Create Instance.
  3. Click Choose MySQL.
  4. Enter myinstance for Instance ID.
  5. Enter a password for the root user.
  6. Click Create.

    You're returned to the instances list. You can click the new instance right away to see the details, but it won't be available for other operations until it initializes and starts.

  1. Download the MySQL Community Server for your platform from the MySQL Community Server download page.
    The Community Server includes the MySQL client.
  2. Install the Community Server, following the directions on the download page.

For more information about installing MySQL, see Installing and Upgrading MySQL.

Install the Cloud SQL Auth Proxy client

The Cloud SQL Auth Proxy binary you download depends on your operating system, and whether it uses a 32-bit or 64-bit kernel. Most newer hardware uses a 64-bit kernel. If you're unsure whether your machine is running a 32-bit or 64-bit kernel, then use the uname -a command for Linux or macOS. For Windows, see the Windows documentation.

Linux 64-bit

  1. Download the Cloud SQL Auth Proxy:
    curl -o cloud-sql-proxy https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.linux.amd64
    
  2. Make the Cloud SQL Auth Proxy executable:
    chmod +x cloud-sql-proxy
    

Linux 32-bit

  1. Download the Cloud SQL Auth Proxy:
    curl -o cloud-sql-proxy https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.linux.386
    
  2. If the curl command is not found, run sudo apt install curl and repeat the download command.
  3. Make the Cloud SQL Auth Proxy executable:
    chmod +x cloud-sql-proxy
    

macOS 64-bit

  1. Download the Cloud SQL Auth Proxy:
    curl -o cloud-sql-proxy https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.darwin.amd64
    
  2. Make the Cloud SQL Auth Proxy executable:
    chmod +x cloud-sql-proxy
    

Mac M1

  1. Download the Cloud SQL Auth Proxy:
      curl -o cloud-sql-proxy https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.darwin.arm64
      
  2. Make the Cloud SQL Auth Proxy executable:
      chmod +x cloud-sql-proxy
      

Windows 64-bit

Right-click https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.x64.exe and select Save Link As to download the Cloud SQL Auth Proxy. Rename the file to cloud-sql-proxy.exe.

Windows 32-bit

Right-click https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy/v2.10.1/cloud-sql-proxy.x86.exe and select Save Link As to download the Cloud SQL Auth Proxy. Rename the file to cloud-sql-proxy.exe.

Cloud SQL Auth Proxy Docker image

The Cloud SQL Auth Proxy has different container images, such as distroless, alpine, and buster. The default Cloud SQL Auth Proxy container image uses distroless, which contains no shell. If you need a shell or related tools, then download an image based on alpine or buster. For more information, see Cloud SQL Auth Proxy Container Images.

You can pull the latest image to your local machine using Docker by using the following command:

docker pull gcr.io/cloud-sql-connectors/cloud-sql-proxy:2.10.1

Other OS

For other operating systems not included here, you can compile the Cloud SQL Auth Proxy from source.

Get the instance connection name

  1. In the Google Cloud console, go to the Cloud SQL Instances page.

    Go to Cloud SQL Instances

  2. Click the instance name to open its Overview page.
  3. In the Connect to this instance section, copy the Connection name. The connection name is in the format projectID:region:instanceID.

Start the Cloud SQL Auth Proxy

Start the Cloud SQL Auth Proxy in its own terminal so you can monitor its output. Replace INSTANCE_CONNECTION_NAME with the instance connection name you copied in the previous step.

For Linux environments, use this command to launch the Cloud SQL Auth Proxy:

./cloud-sql-proxy INSTANCE_CONNECTION_NAME

In PowerShell on Windows, use this command to launch the Cloud SQL Auth Proxy:

.\cloud-sql-proxy.exe INSTANCE_CONNECTION_NAME

A message similar to the following appears:

Listening on 127.0.0.1:3306 for INSTANCE_CONNECTION_NAME
Ready for new connections

Run the following command:

mysql -u root -p --host 127.0.0.1 --port 3306

At the Enter password: prompt, enter the password of your MySQL root user account.

Verify that the MySQL prompt appears. You have connected to your database using the mysql client.

Return to the terminal window where you started the Cloud SQL Auth Proxy. You should see a message similar to the following:

New connection for myInstance
