I made instance in Google Cloud > Storage > SQL > MYSQL. Now I have to import database in it so I am trying to connect to MYSQL
using adminer, but it gives following error
SQLSTATE[HY000] [2002] Operation timed out
I also tried via HeidiSQL > MariaDB or MYSQL (SSL Tunnel) but here also it does not connect and gives error
https://prnt.sc/o58in0
I am mentioning
Host: Public Ip of SQL instance
Username: root
Any suggestions, what could be the fix?
Your error typically means that a firewall blocked your connection attempt.
For Cloud SQL, this typically means that you have not enabled instance-level access.
Since your error is 10060, which is a Windows WinSock error message, I am assuming that you are running on Windows. The steps are similar for Linux.
There are two methods to enable access to Cloud SQL:
Cloud SQL Proxy
This is the recommended method and is secure. Download and install the Cloud SQL Proxy to your the computer that you want to connect from. If you have set up the Cloud SDK (gcloud), Cloud SQL Proxy will use your Cloud SDK credentials. If not, then you will need to create and download a service account with (usually) the Cloud SQL Client role.
You will need the "instance connection name" from Cloud SQL Instance details page.
Download Cloud SQL Proxy (link) to your computer. Remember the full path to the program. Save the program as "cloud_sql_proxy.exe"
Start the Cloud SQL Proxy
[full_path_to_program]\cloud_sql_proxy -instances=[INSTANCE_CONNECTION_NAME]=tcp:3306
OR
[full_path_to_program]\cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:3306 -credential_file=[PATH_TO_KEY_FILE]
Connect using mysql.exe: `mysql -u USERNAME -p --host 127.0.0.1
Public IP Method
The second method is not secure unless you also enable SSL, which I will not cover in this answer. I do not recommend this method except for knowledgeable persons.
Figure out what your public IP address is. Go to any website such as "MXToolbox" https://mxtoolbox.com/whatismyip/
Go to the Google Cloud Console
Go to the Cloud SQL Instances Details page
Select the Connections tab
Click Add network
In the Network field, enter your Public IP address using CIDR notice: eg 145.11.22.33/32
Enter a name such as "My Home IP"
Click Done
Click Save
Note: Most home Internet services change your Public IP address periodically. This means that you will need to update your Public IP address in Cloud SQL if you are using the second method.

I have a .net core app installed as a docker on google cloud run, this app that needs to be connected to cloud sql (mysql).
When using the private ip address it, it's not working.
When using public IP, it's working, but It's not a good solution for production.
this is my connection string:
"ConnectionString": "server=10.4.16.6;database=mydb;user=root;pwd=mypwd"
When I create the app, Im able to select the database i need to connect to:
But this is not helping to connect.
The relevant docs are explaining how to do it for python and java explictly.
If you do not want to use public IP then you would need to rely on service account to connect to Cloud SQL. However, .net MySQL driver has no understanding of GCP IAM and Service accounts. So you will need to use a proxy called Cloud SQL Proxy. Cloud SQL Proxy understands IAM and Service accounts.
The flow will basically look like this:
Your app -> Regular MySQL Port -> Cloud SQL Proxy(Installed in the
app's network or locally) -> CloudSQL
You will need to do the following:
Create a service account
Assign the role of Cloud SQL Client to the created service account
Download the service account key in the json format
Set env variable GOOGLE_APPLICATION_CREDENTIALS=C:\Downloaded.json
Download Cloud SQL Proxy
Run it `cloud_sql_proxy -instances=projectname:regioname:instanceid=tcp:3306
At this point you MySQL proxy ready to accept connections at 3306, modify the connection string to take localhost or wherever you installed the Cloud SQL Proxy.

You can create the Cloud Run app from the console (and select the Cloud SQL Connection) or from the gcloud command line and specify
--add-cloudsql-instances <INSTANCE-NAME> --set-env-vars INSTANCE-CONNECTION-NAME="INSTANCE_CONNECTION_NAME"
These settings automatically enable and configures the Cloud SQL proxy. You can connect to the proxy, from your asp.net Core app, using the unix domain socket using the format: /cloudsql/INSTANCE_CONNECTION_NAME.
I used the following connection string in my appsettings.json and it worked for me:
"Server=/cloudsql/INSTANCE_CONNECTION_NAME;Database=DB_NAME;Uid=USER_NAME;Pwd=PASSWORD;Protocol=unix"
NB. Make sure you have given the service account that your Cloud Run app is running under Cloud SQL Client role in IAM
I have a flask server which I want to deploy on Google Cloud Platform. The code uses MySQLdb library to connect with local MySQL instance in the following manner:
#app.route('/show_table', methods=['POST'])
def login():
db = MySQLdb.connect("localhost", "root", "", "db_name")
cursor = db.cursor()
query = "select * from table_name;"
cursor.execute(query)
res = cursor.fetchall()
return res, 200
But instead of local MySQL instance, I want to connect this code to Cloud SQL so that it reads data from the cloud. What changes should I make to this code? I have currently created a project in Google Cloud Platform and a Cloud SQL instance inside this project. I have also created the required tables inside this instance by following
this tutorial.
You shouldn't have to change your code too much, it just depends on how you're going to connect to the database. The Google documentation has step by step information on how to connect to Cloud SQL from an external application.
Since you're not using Java or GO, there's two options:
Use the Cloud SQL proxy
Whitelist the public IP address of your server on the Cloud SQL instance page
All the steps are in the documentation, but it basically says that if you use the proxy, you'll need to enable the Cloud SQL Admin API, install the proxy client on your local machine and authenticate it. There's a few authentication options but the recommended way is creating a credentials file from a service account using the console and passing the file as a parameter when you first start the proxy. Once you've got the proxy running the documentation has examples on how to connect using either TCP or UNIX sockets. With TCP you'll be using the proxy as localhost so you won't have to change your code. Using UNIX sockets you'll use the instance connection name which you'll find in your instance details on the GCP console. MySQLdb supports both.
With the second option you need to allow access to your Cloud SQL instance from a specific IP address range. Go to the connections tab in your Cloud SQL instance details page and add the IP address (using CIDR notation) you want to use to connect to your database. Once it's whitelisted then you can use the Public IP of your Cloud SQL instance, which you'll find in instance details, in place of localhost to connect to your database.
I don't understand why I got inconsistent connection from my local MySQL Workbench to Google Cloud SQL.
Something, I can connect to my database the first time, sometimes, I need to try multiples times before getting a connection. Sadly, most of the time, it's not working.
Because I can rarely connect to the database, what kind of configuration can cause this problem?
Here's some infos:
My application hosted on Google Compute Engine don't have any connection problem.
My public IP (personnal computer) is added to the Authorised networks in my Google Cloud SQL instance. See: Enabling public IP and adding an authorized address
I have added a Firewall rules to allow port 3306 in Google Cloud VPC network
SSL is currently disable for the testing purpose
I followed these instructions: How to connect to your Cloud SQL instance database with MySQL Workbench
For the benefit of future readers, the result of the comments above was:
The problem was that the client was alternating between two possible external IP addresses. One had been authorized to access Google Cloud, and the other one had not been authorized.
Enable all client IP addresses to connect, and that should fix it.
I'm trying to connect my local MySQL to a test 2nd generation MySQL instance on Google SQL platform using the following command on my windows laptop.
mysql --host=130.211.xx.xx --port=3306 --user=root --password
I double checked my IP address with whatismyIPaddress.
I can connect via Google Cloud Shell on the Google Platform itself and also ping the IP address from the local cmd prompt.
As a troubleshooting step I have disabled the local firewalls on my laptop and granted full access to 0.0.0.0/0 to allow all connections on the google platform console.
still no joy from either a cmd line connection on windows or using a putty client, can anyone give me any further pointers on the missing step?
Cheers..
If you are behind a NAT your IP might change which prevents you from accessing the Cloud SQL instance. I would recommend setting up access using SSL certificate. More information about the setup can be found in this Help Center article.
You may need to allow remote connections to your remote database in the server and database configuration. These kinds of connections are typically disabled by default.
I can't connect Google Cloud SQL from GCE even I added public IP (external IP) of my GCE instance as a authorized network. It works when I add "0.0.0.0" into authorized network. Obviously I don't want to do that. The authorized network setting may be the cause. But I can't find out it. Does anyone know about this.
I'm using Google Cloud SQL version 2 beta. I am trying to connect from GCP cloud console. Although it may be not necessary, I changed external IP setting from ephemeral to static but it didn't work.
mysql -u root -p -h xxxx <--- I can login normally if I add "0.0.0.0" into authorized network.
I've double checked this same question..
Linking Google Compute Engine and Google Cloud SQL
1. Ensure your Cloud SQL instance has an IPv4 address.
2. Find out the public IP address of your GCE instance and add it as an authorized network on your Cloud SQL instance.
3. Add a MySQL username and password for your instance with remote access.
4. When connecting from GCE use you standard MySQL connection system (e.g. mysqli_connect) with the username and password you just set up, connecting to the IPv4 address of your Cloud SQL instance.
Edit 1
I noticed this description.
Note: Connecting to Cloud SQL from Compute Engine using the Cloud SQL Proxy is currently available only for Cloud SQL Second Generation instances.
https://cloud.google.com/sql/docs/compute-engine-access
Does it mean that I have to use the Proxy..?
Edit 2
$ mysql -u root -p -h (Cloud SQL Instance's IP)
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '(Cloud SQL Instance's IP)' (110)
Edit 3
Does it mean that I have to use the Proxy..?
According to the official document as Vadim said, Cloud SQL Proxy seems to be optional but it sounds better for security, flexibility and also the price. (static IP will be charged. However, the proxy setting may be complicated for me..)
https://cloud.google.com/sql/docs/compute-engine-access
If you are connecting to a Cloud SQL First Generation instance, then you must use its IP address to connect. However, if you are using a Cloud SQL Second Generation instance, you can also use the Cloud SQL Proxy or the Cloud SQL Proxy Docker image.
Edit 4
I found the reason... I was stupid... I tried connect from Google Cloud Shell but that was not my gce instance. It works when I try to connect from my gce instance.
Did you add the public IP of the GCE VM under authorized networks?
From your post:
2. Find out the public IP address of your GCE instance and add it as an authorized network on your Cloud SQL instance.
The official documentation is here:
