Grant access to a EC2 and RDS instances [duplicate] - mysql

I'm using AWS for my project and Laravel 5. Just installed my laravel project in the EC2 and set up a DB in RDS. I imported the .sql file using mysql workbench. In my .env I set up the host, the DB name, user and password but when I go to the project in the browser I get an error:
PDOException in Connector.php line 55:
SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'blue*****.************.us-west-2.rds.amazonaws.com' (4)
Put the * for security reasons. So what could be wrong?
Update:
When I tried to connect to the RDS instance using the command line I got:
ERROR 2003 (HY000): Can't connect to MySQL server on 'blue****.**********.us-west-2.rds.amazonaws.com' (110)

The reason you are not able to connect to the RDS instance from the EC2 instance has to do with security group.
Before your EC2 instance can communicate with the RDS server, you need to configure a security group for the RDS.

How to solve error An exception occurred in driver: SQLSTATE[HY000] [2002] Connection timed out error in symfony 4 project deployed on amazon aws

My symfony project is working fine on localhost . i am able to connect to amazon aws rds on localhost .I have set mysql configuration in .env file of the symfony project .
when i have uploaded/deployed the same project on the amazon-aws .
i am getting this error :
An exception occurred in driver: SQLSTATE[HY000] [2002] Connection timed out
Question:
How can i debug this error ?
Is this issue is related to the amazon aws configuration ?
There might be multiple places it is stopping to connect to rds. Following might be some of the reasons:
AWS Server outbound rule might be stopping to connect to the rds. If it is in a different security group or vpc.
RDS Secruity group inbound rules it might not be allowing to connect to the aws server.
You can try connect to rds from the server by using mysql command line.

Amazon RDS: Your connection attempt failed for user 'master' to the MySQL server

I am unable to connect to the MySQL Amazon RDS instance I created.
I am following the AWS RDS tutorial to connect and entered:
The endpoint in the "Host" on the workbench
Credentials including the username and the password
Port is set to 3306
I get the error:
Cannot Connect to Database Server
Your connection attempt failed for user 'master' to the MySQL server at xxxx.rds.amazonaws.com:3306:
Can't connect to MySQL server on 'xxxx.amazonaws.com' (10060)
Here is the link to the tutorial i am following Tutorial on setting up & connecting to Amazon RDS
Things to check:
Since you are connecting from the Internet, the Amazon RDS database must be launched in a public subnet
When launching the Amazon RDS database, select "Publicly available"
Assign a Security Group that permits Inbound traffic on port 3306 from your IP address (or 0.0.0.0/0, but that is much less secure)

Can't connect a DB to AWS

Django on EC2 using RDS

I have a Django App running on an EC2 instance and trying to connect to a RDS mysql Database instance.
I have created the RDS database and added a rule to the RDS Security group that allows for EC2 Security Group.
In my settings.py file, I have added the HOST to be the RDS EndPoint and the Port to be 3306 - along with the DB name, user and password.
I have installed libmysqlclient-dev, MySQL-python and mysql-client on the EC2 instance.
When I run ./manage.py syncdb, I get this error:
super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")*
It looks like it is trying to connect to a local mysql server (which of course is not there, since I want it to connect to an RDS).
How can I get past this?
You don't set rds in default, or you loading wrong settings file. Python mysql trying to connect with localhost base, through socket (it's when HOST field is empty). You can try print DATABASE['default']['HOST'] in settings, or django shell to check host in settings.
