Hi (Sorry for my English)
I am a new user to Google Cloud SQL
I create a "Instance" and I have upload my database.
I request an Ip and also I have add on "Authorized Networks" all of my VPS ip's
also I add my current IP from my ISP.
I try to connect from my VPS with
mysql_connect("Requested IP", "root", "PASSWORD")
but nothing happen and I receive this:
Can't connect to MySQL server on 'XXX.XXX.XXX.XXX' (4)
Also I try to connect from my PC with mysql client like
mysql --host=Requested IP --user=root --password=PASSWORD
and I receive this:
ERROR 2005 (HY000): Unknown MySQL server host
What wrong I have done ?
Thank you
You should add your public IP as an Authorized Network in Cloud SQL.
Go to your instance configuration screen -> Access Control tab and on Authorized Networks add your public IP address.

I am trying to connect with the username, password I've set up with the given host name. I can't connect. I've checked the security group to be configured correctly at PORT allowing incoming from "My IP" which populated my IP there.
What else could I be doing wrong?
When I try to get into the DB using the following command in my terminal:
mysql -h [aws-hostname-endpoint] -P 3306 -u admin -p
I get:
ERROR 2003 (HY000): Can't connect to MySQL server on [aws-hostname-endpoint] (60)
When you setup your RDS instance, also be sure to allow for public access if you want to connect to it from your development machine. SO two things to check:
allow public access for the RDS instance
make sure you inbound rules are setup to allow for a connection from your IP address.
Once you do these two tasks, you will be able to connect via a tool such as MySQL Workbench.
These RDS endpoints are not public (and they shouldn't be), so you can't use them on your computer to connect to them. You could make these endpoints public, but that's not a good idea/design. It's better if you try to connect inside an AWS environment (i.e EC2). Then you can restrict access to that using SSH keys.
We usually create a Bastion server for this purpose to act as a proxy, then you can use an SSH tunnel to connect to the RDS instance. Then all your traffic will be routed through the Bastion server in a secured tunnel.
I have created a RDS MYSQL database and have set public access , modified VPC security groups enter link description here
but I am still not able to connect to the MYSql. Telnet also fails Could not open connection to the host, on port 3306: Connect failed
Connection from mysql workbench gives the following error Can't connect to MySQL server at .... (10061)
I've checked various posts in stack exchange on this error . But still unable to figure out what is missing.
Kindly let me know what is missing.
Some things to check:
The RDS instance should be configured as publicly accessible
The RDS instance should be launched in a public subnet
The Security Group should permit Inbound access for your IP address for port 3306
Your network must not be blocking the connection (try from another network, such as work/home or tethered via your phone)
I had the same problem and added a custom inbound rule in my security group with the port number from my database and the source set to my IP. this fixed it for me and telnet started working.
So, I have already created a new security group rds_access for my RDS instance with Inbound-> >Source parameter set to 0.0.0.0/0, and updated the instance so in the 'Security groups' section on RDS Dashboard I have: rds_access (sg-xxx)( active )
In MySQL Workbench "Edit" section of my connection, in the tab "Remote Manager" I have set the value of "Native Windows remote management" radio button to active and "Hostname" parameter to 0.0.0.0.
The instance and the database connect successfully.
In my web-application running on pythonanywhere I'm still getting this error:
OperationalError: (2003, "Can't connect to MySQL server on 'bachelor-diploma-db.cx0stetemb8k.eu-central-1.rds.amazonaws.com' ([Errno 111] Connection refused))
Before uploading my app on pythonanywhere, I've tested it on localhost and everything was working fine. Also I have rebooted both the RDS instance and MySQL database.
Please, tell me what am I doing wrong and how to fix this issue?
UPDATE:
In order to connect to MySQL server I use flask-mysql. Here's the code snippet:
from flaskext.mysql import MySQL
api = Api(app)
mysql = MySQL()
app.config['MYSQL_DATABASE_USER'] = 'user'
app.config['MYSQL_DATABASE_PASSWORD'] = 'password'
app.config['MYSQL_DATABASE_DB'] = 'bachelor_diploma_db'
app.config['MYSQL_DATABASE_HOST'] = 'bachelor-diploma-db.cx0stetemb8k.eu-central-1.rds.amazonaws.com'
mysql.init_app(app)
and then in methods I use:
conn = mysql.connect()
Probably because you're on a free PythonAnywhere account and free accounts can only connect out on http(s) to a specific whitelist of sites.
You need to connect to the actual publicly visible endpoint for your RDS instance. 0.0.0.0/0 is just a placeholder meaning any IP address. From the RDS console, find the details information. Under "Connect" you should see an endpoint looking something like this:
mysql–instance1.123456789012.us-east-1.rds.amazonaws.com
From the command line your connection string would look something like this:
mysql -h mysql–instance1.123456789012.us-east-1.rds.amazonaws.com
-u ec2-user -pPASSWORD yourdb
If the above does not resolve the problem, then you may also want to make sure that port 3306 (used by MySQL) is not behind a firewall.
See the AWS documentation for more information.
The subnets that the RDS instance is running in also needs to be public ,this can be done by creating a subnet group in rds and adding public subnets to it, took me hours of fiddling to work this one out
I have launched an AWS EC2 Windows_Server-2016 instance.
Since this server is windows based,I can successfully connect to
it using remote desktop connection by entering the username,
password and a .ppk file.
I have installed MySQL server on the instance and created a user
that is allowed to login with any ip i.e by providing the '%' sign.
Here's what my AWS instance security group looks like :
I have tried connecting to the MySQL server using SQLYOG using 2
different scenarios :
Tried connecting by using the aws public ipv4 address as a host field and
using mysql username & password
Tried connecting by creating an SSH connection i.e providing server
username/password and .ppk file in SSH connection panel & then
providing mysql host/username and localhost in mysql connection
panel
None of the methods used allows me to connect.I try same procedure with a linux based server and can connect successfully. Please let me know where am I going wrong while using a windows based MySQL hosting.
MySQL has an extra level of IP protection for remote clients. You have to GRANT access to the remote ip(your house of office) to be able to connect. As root, you have to do :
GRANT ALL ON <db>.* TO '<username>'#'<remote ip>' IDENTIFIED BY '<remote_password>';
Where is the DB you are trying to connect to etc.
I'm trying to connect to a remote databases using an ip address ,login and password,the instance name is SQLEXPRESS ,Any idea how can i connect to this databases with workbench ?
Just replace the localhost server (or IP) with the correct IP.
You might need to create a dedicated user for external connection, since default root user is restricted to connect only from localhost.
