I need to use MySQL to send queries to a Google Cloud SQL database set up. I already have an instance created and a user, and I am able to access the database through the Cloud Shell. I can't seem to find the credentials to log into the database (host name, username, password, port and socket), and I'm not sure how to access them through the shell.
You can find the available methods to connect to your Cloud SQL instance here.
Connecting from an IP address without SSL is probably the easiest one:
In the Cloud Console, go to the cloud SQL instances screen and click on your instance’s name.
In the overview tab, take note of the Primary IP Address, you’ll use it instead of a hostname.
In the users tab, you can create a new user or reset the password of an existente one, including the root user.
In the authorization tab, add the ip or ip range where you are attempting the connection from, so Cloud SQL accept connections from your client (more on this here).
Start your mysql client as follows (note the port is not necessary as the default one is used):
mysql --host=[INSTANCE_IP_ADDR] --user=[USER_NAME] --password

I am brand new to RDS and have only used postgres through Rails and/or Heroku for the most part, so not that deep into database management. All I am trying to do is verify I can connect to the RDS instance I just created on AWS, but it is hanging, psql reporting this after hanging for about 30 seconds or a few minutes I guess:
$ psql postgresql://myuser:mypass#myawshost.rds.amazonaws.com:5432/my-db-name
psql: error: could not connect to server: Operation timed out
Is the server running on host "myawshost.rds.amazonaws.com" (<the ip address>) and accepting
TCP/IP connections on port 5432?
How do I connect to my AWS RDS instance from localhost?
I am sure I have the correct username and password.
I am sure the host is correct.
I am not sure if I should be including the port.
I am not sure if I am supposed to put a DB name, as under the "Configuration" tab in the RDS admin console for my database, it says DB instance ID: my-db-name, Engine version: 13.3, DB name: -, I am not sure if that - is my actual postgres db name or my-db-name is....
I tried this with the db name and it still hangs:
$ psql postgresql://myuser:mypass#myawshost.rds.amazonaws.com:5432/-
I edited the security group which is linked under the VPC security groups section of the Connectivity & security tab of https://console.aws.amazon.com/rds/home, so it allows all incoming connections. I also tried limiting to just my IP address as incoming connections.
Any help would be appreciated, thanks. Not sure why it would just be hanging. I have used a local version of postgres just fine, but connecting to postgres RDS is not working.
Underneath the Connectivity and Security > Security section I just noticed it says Public accessibility: No. Must I enable something else? There is also one VPC, one Subnet group, and several Subnets, which I don't know too much about, must I do something there?
Finally, "status" says Available with a green light, so things seem fine there.
I found a useful link in AWS knowledge center, I hope this will help you.
Btw if your RDS is deployed in a public subnet, yes you need to enable if you want to access RDS over the internet.
My DB instance is in a public subnet, and I can't connect to it over the internet from my local computer
This issue can occur when the Publicly Accessible property of the DB instance is set to No. To check whether a DB instance is publicly accessible, you can use the Amazon RDS Console or the AWS CLI.
To change the Publicly Accessible property of the Amazon RDS instance to Yes:
Verify that your VPC has an internet gateway attached to it. Make sure that the inbound rules for the security group allow connections.
Open the Amazon RDS console.
Choose Databases from the navigation pane, and then select the DB instance.
Choose Modify.
Under Connectivity, extend the Additional configuration section, and then choose Publicly accessible.
Choose Continue.
Choose Modify DB Instance.
Note: You don't need to choose Apply Immediately. For more information about how Apply Immediately can affect downtime, see Using the Apply Immediately parameter.

I am not able to connect through pgAdmin4 to Google Cloud SQL.
Following are the credentials I am providing and getting the error messege:
If you are configuring access for public IP connections, follow the next steps to connect with PgAdmin:
1) Create your PostgreSQL instance in Google Cloud Platform.
2) While creating the instance,
In Instance ID tab, write a name for your instance
In Default user password tab, write a password.
Choose the region.
Click on configuration options, go to Connectivity, enable Public IP, under Authorized networks, add network and their write the IP address of your PC. You can check the IP address in the link .
Click on create.
Then in PgAdmin:
1) In Host name/address put Public IP address of the instance.
To connect with Google Cloud SQL using pgadmin client, you can use cloud_sql_proxy
These steps need to follow:
Establish connection to Postgres.
cloud_sql_proxy -instances=<connection string>=tcp:5433
You will get connection string from GCP here
After executing cloud_sql_proxy, you will see something like this
Now create a new server connection using pgadmin client.
If you followed those steps properly it will connect and can use like local pgadmin.
Nibrass H has perfectly answered this question.
But I would like to add that if you have already created the Instance, then you can click on 'Edit Instance' and Add your IP in 'Connections'.

I'm trying to connect to a Google Cloud SQL instance using dblink, which works well when setting up my username and password in the connection string, but I would like to save my Client credentials in the SQL instance not to have the need to explicitly put my password in the connection.
The .pgpass file which will used is the one that belongs to the OS user which is running the local database ('~/postgres/.pgpass', in most cases). And then for security reasons, it works only if you are locally a superuser. Can you meet those criteria?
but I would like to save my Client credentials in the SQL instance
What does "SQL instance" mean? I would not think that .pgpass would count as being inside the SQL instance.
An alternative solution is create a foreign server with "postgres_fdw". This doesn't seem to be documented (edit: it is documented here, but uses dblink_fdw not postgresql_fdw), but you can pass the name of a "postgres_fdw" foreign server (in single quotes) to dblink functions as the connection string. It will then pull the password to be used from the USER MAPPING for that server and user. I would think the USER MAPPING counts as inside the "SQL instance".
I have a Google Cloud SQL instance with a public IP, only accessible to whitelisted IP and through an SSL connection.
I'd like to know how I can connect to this database from Google Colab with Python.
If I try to connect like any external application, the connection is refused since the ip of the "client" is not whitelisted (and I can't whitelist it since I don't it and it's highly probable it's volatile)
Is there a shortcut, like with Google App Engine to connect to the database using its instance and a google client?
Thanks
A little late to answer, but I think I have a solution and it involved using the Cloud SQL Proxy. Overall, you first need to use the Gcloud SDK (included with Colab) to authenticate, then install the proxy, then spin it up. I did this in two blocks
# gcloud login and check the DB
!gcloud auth login
!gcloud config set project [YOUR PROJECT ID]
!gcloud sql instances describe [YOUR CLOUDSQL INSTANCE ID]
This last line will output a dump of info and we want connectionName in particular. The next block then downloads the proxy and tells it to proxy for that CloudSQL instance:
# download and initialize the psql proxy
!wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.amd64 -O cloud_sql_proxy
!chmod +x cloud_sql_proxy
# "connectionName" is from the previous block
!nohup ./cloud_sql_proxy -instances="[connectionName]"=tcp:5432 &
!sleep 30s
Later on you can (and I've found it helpful) to check the proxy's logs with
!cat nohup.out
And finally, you can construct a connection with the address 127.0.0.1:5432 (or whatever port you set above. I did so with psycopg2 like this
conn = psycopg2.connect(
host='127.0.0.1', port='5432', database=[YOUR DB NAME],
user=[USERNAME], password=[PASSWORD])
It seems to work, though it's definitely a bit slower than a direct connection.
Go to the Cloud SQL Instances page in the Google Cloud Console.
Go to the Cloud SQL Instances page
Click the instance name to open its Instance details page.
Select the Connections tab.
Select the Public IP checkbox.
Click Add network.
In the Network field, enter the IP address or address range you want to allow connections from.(for colab add two networks:-34.0.0.0/8 and 35.0.0.0/8)
Use CIDR notation.
Optionally, enter a name for this entry.
Click Done.
Click Save to update the instance.
and i used pymysql module to connect to database and it worked!!!
in colab,
`pymysql.connect(host="enter publicIP present in overview of sql instance", user="root",passwd="", db="your database name") `
The most simple way for SQL SERVER, as long as you allow the two colab networks already mentioned: 34.0.0.0/8 and 35.0.0.0/8
!pip install pymssql
import pymssql
conn = pymssql.connect(server='public IP',user='user',password='pass',database='dbname')
cursor = conn.cursor()
cursor.execute('SELECT TOP 10 * FROM table;')
row = cursor.fetchone()
while row:
print(str(row))
row = cursor.fetchone()
I can't seem to connect to Cloud SQL with Workbench. I keep getting this error.
Failed to Connect to MySQL at CLOUD-SQL-IPv4:3306 with user root
Access denied for use 'root'#'WHITE-LISTED-IP-ADDRESS' (using password: YES)
I have white listed my IP.
I have set an IP for the SQL instance.
I have checked the username and Password several times.
Any idea why this is happening?
It seems you have to create a new user in the Google Cloud Console with the host name set to %(any host). You can't seem to connect using the root user.
Is it possible to connect with the #root user but after you finish the setup you have to restart the sql server.
What is important to set up an SSL certificate if you connect to you production database, but if you only try it out you can allow unsecured connection. Another important thing is to add your IP to the Authorised Networks in the Connection tab.
