I am trying to connect to cloud sql hosted in gcp from eclipse, not able to do so. I have whitelisted my ip using the connection settings on cloud sql instance. I have added the driver also in eclipse for mysql.
I think I am making mistake in constructing the connection string. Please refer below details.
connectionName: abc-dev:europe-west1:abc-instance
So in connection section
database: abc-dev:europe-west1:abc-instance
url: jdbc:mysql://35.233.100.100:3306/abcInsoles
user: root
password: xyz123
It throws exception:
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
I am running it from local.
Can you throw some insights?
Many thanks.
The "database" value is incorrect - this is the name of the database on the instance itself (not the instance's connection string).
Since you are using Java, you may be interested in the Cloud SQL JDBC Socket Factory - it allows you to connect to the Cloud SQL instance without whitelisting an IP.

I hope you are well.
I wan't to connect Google Datastream with MySQL database hosted into Cloud SQL by using private connection.
I have conected by the public internet using Public IP but I need to connect through VPC peering for security, documentation indicates that the following should be done: https://cloud.google.com/datastream/docs/private-connectivity
I have been tring to connect across Cloud SQL Auth Proxy follow this documentation and I have already connected the proxy to Cloud SQL: https://cloud.google.com/sql/docs/mysql/connect-admin-proxy#tcp-sockets
In every occasion I see the same error, no matter what ip configure it always changes to another ip.
For example, the follow image show the perfil configuration with Cloud SQL Auth Proxy internal IP 10.128.0.2 set up.
And, when I try to test, I've seen that the MySQL IP change for 192.168.5.236
In general, this is a MySQL client-side error code. The possible causes for this error are:
MySQL Server not running, or
Firewall configuration on the Windows server blocking access on port 3306
=> To troubleshoot the given error message, please follow the below mentioned steps:
Verify MySQL server is running and use the ping command to check the client-server connectivity. For Example: ping server_ip_address
To connect to a Cloud SQL instance using private IP, the Cloud SQL Auth proxy must be on a resource with access to the same VPC network as the instance.[1]
When you start the Cloud SQL Auth proxy, to ensure it is using the private IP, please make sure to pass the flag:
-ip_address_types=PRIVATE
Also,verify the firewall configuration and make sure the port 3306 is not blocked.
You can also view the mysql config file[2] and check if there is a bind-address relevant to it. If there is a bind-address, comment it out using the # character.
[1] https://cloud.google.com/sql/docs/mysql/connect-admin-proxy#private-ip
[2] How do I find the MySQL my.cnf location
In my case I have the Cloud SLQL Proxy mounted in compute engine and Mysql in Cloud SQL.
The solution was the following:
I needed to create a ingress firewall rule allow the ip range from the Datastream Private Connection (I needed to connect Datastream across a private connection for governance) to Cloud SQL Auth Proxy IP Range in tcp:3306.
You can test your connection throght Connectivity Tests
Problem
I launched a MySQL RDS instance and was able to successfully connect to it using MySQL Workbench. However, I am still not able to connect to it from my local workstation using the following URI:
'mysql+pymysql://user:password#db_identifier.XXXXXXXXXX.us-east-1.rds.amazonaws.com:3306/db_name'
or the same URI without the port:
'mysql+pymysql://user:password#db_identifier.XXXXXXXXXX.us-east-1.rds.amazonaws.com/db_name'
The error that I receive when I specify this as my database URI and execute a db.create_all() command is:
sqlalchemy.exc.OperationalError:
(pymysql.err.OperationalError)
(2003, "Can't connect to MySQL server on 'db_identifier.XXXXXXXXXX.us-east-1.rds.amazonaws.com'
([WinError 10060] A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection failed because
connected host has failed to respond)")
Question
What can I do to connect using pymysql? And why would it connect with MySQL Workbench and not through this URI?
Context
I am following the tutorial here. This uses SQLAlchemy to execute the SQL statements in Python.
The RDS instance (and its associated subnet/VPC) have the following:
a security group open on port 3306
NACL rules that allow incoming and outgoing traffic
Public Accessibility set to "Yes"
Check my answer on this post, it could be something about the "Public accesibility" option in your rds "Connectivity and Security" section as described here;

In our company we use few AWS RDS MySQL instances while few of those aren't in any VPC (we have created those 3 years ago).
I need to connect to such an instance using Microsoft SQL Server Management Studio but when I'm trying to do so I'm getting following error after few seconds:
TITLE: Connect to Server
Cannot connect to host_path.amazonaws.com.
------------------------------ ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(Microsoft SQL Server, Error: 53)
For help, click:
http://go.microsoft.com/fwlink?ProdName=Microsoft%20SQL%20Server&EvtSrc=MSSQLServer&EvtID=53&LinkId=20476
The network path was not found
If I add the port after the host path like described there
I'm getting different error:
TITLE: Connect to Server
Cannot connect to host_path.amazonaws.com,3306.
------------------------------ ADDITIONAL INFORMATION:
Internal connection fatal error. Error state: 18 (System.Data)
The thing is that the link above they are talking about DB instance that is within VPC but our isn't.
Did anyone of you stuck with similar issue earlier and maybe know how to resolve that or at least can point me out to the correct way?
I've Googled a lot regarding this issue but every forum or FAQ says about DB instance within VPC which isn't my case.
In screenshot below
you can see the connection window within the program, all sensitive data has been painted over.
Thank you in advance.
Pretty sure you cant directly connect from SSMS to a MySQL database. I think you can setup a "Linked Server" (basically an ODBC driver/datasource, then connect to your localhost, which in turn talks to MySQL).
See: https://learn.microsoft.com/en-us/sql/relational-databases/linked-servers/create-linked-servers-sql-server-database-engine?view=sql-server-2017
I'm assuming your requirement for SSMS is that you plan to reference data from both SQL Server and MySQL? If so, it should work, but its performance wont be great.
I'm trying to connect my server code running as a Docker container in our Kubernetes cluster (hosted on Google Container Engine) to a Google Cloud SQL managed MySQL 5.7 instance. The issue I'm running into is that every connection is being rejected by the database server with Access denied for user 'USER'#'IP' (using password: YES). The database credentials (username, password, database name, and SSL certificates) are all correct and work when connecting via other MySQL clients or the same application running as a container on a local instance.
I've verified that all credentials are the same on the local and the server-hosted versions of the app and that the user I'm connecting with has the wildcard % host specified. Not really sure what to check next here, to be honest...
An edited version of the connection code is below:
let connectionCreds = {
host: Config.SQL.HOST,
user: Config.SQL.USER,
password: Config.SQL.PASSWORD,
database: Config.SQL.DATABASE,
charset: 'utf8mb4',
};
if (Config.SQL.SSL_ENABLE) {
connectionCreds['ssl'] = {
key: fs.readFileSync(Config.SQL.SSL_CLIENT_KEY_PATH),
cert: fs.readFileSync(Config.SQL.SSL_CLIENT_CERT_PATH),
ca: fs.readFileSync(Config.SQL.SSL_SERVER_CA_PATH)
}
}
this.connection = MySQL.createConnection(connectionCreds);
Additional information: the server application is built in Node using the mysql2 library to connect to the database. There are no special firewall rules in place that are causing network issues, and that's confirmed by the fact that the library IS connecting, but failing to authenticate.
After setting up Cloud SQL Proxy I managed to figure out what the actual error was: somewhere between the secret and the pod configuration an extra newline was being added to the database name, causing any connection attempt to fail. With the proxy set up this was made clear because there was an actual error message to that effect displayed.
(notably all of my logging around the credentials that I was using to validate that the credentials were accurate didn't explicitly display the newline and was disguised by the fact that the console display added line breaks to wrap the display, and it happened to line up exactly with where the database name ended)
Have you read the documentation on https://cloud.google.com/sql/docs/mysql/connect-container-engine ?
In Container Engine, you need to set up a Cloud SQL Proxy container alongside your application pod and talk to it. The Cloud SQL Proxy will then make the actual call to Cloud SQL service.
If the container worked locally, I assume you have Application Default Credentials set on your development machine. It could be failing because those credentials are not on your container as a Service Account file. Try configuring a Service Account file, or create your GKE cluster with --scopes argument that gives your instances access to Cloud SQL.
I'm using Outsystems Service Studio to develop a web application. I need to configure a connection to access a local server database. I get "Connection String test failed: Unable to connect to any of the specified MySQL hosts." I just figured out I can't connect using "localhost", because the Outsystems server is not local, but I'm not able to find a solution. what is wrong? Other details:
MySQL Server is up and running
I selected MySQL in DBMS
Inserted my schema name
Inserted the username (with all privileges granted)
Inserted the user password
Tried both basic and advanced configuration. I inserted j"dbc:mysql://127.0.0.1:3306/mydb?user=outsystems2" as connection string parameters and I get "Connection String test failed: Keyword not supported.Parameter name: mysql://127.0.0.1:3306/mydb?user". I know this connection string can't work , but I'm not able to find a functioning one. I've read many guides about this configuration, but no solution was found. Thank you all for your time and help, feel free to ask for more details
Luciano,
Is your OutSystems environment on-premises or in the cloud? Either way, you need to make sure that this server is able to reach - it as connectivity - to your MySQL database server. Using localhost or 127.0.0.1 is pretty much the same thing as this is an address for the machine where the request is running, which is, in this case, the OutSystems server. Do you have the MySQL database on your local machine? This is not a good approach as you will need to have an address that won't change otherwise the connection won't be stable and you'd have to reconfigure it all the time.
Regards
