I have set Ec2 Linux server with only PHP is installed in it not mysql.
I have separately configured RDS
Installed workbench and logged in using endpoint of RDS and username and password
In workbench DB connection done. I imported my local DB to RDS
Now In my Ec2 I onlu have PHP not mysql as my db is in RDS
In my ec2 php is running In check it with simple hello world echo file.
But mysqli_connect script is giving connection time out error. I used the same credentials as I used to connect to workbench. And I am also using the right script of mysqli_connect.
My doubt is Is it because of I did not installed mysql in my ec2 linux server. But Why I need mysql in ec2 if I have successfully setup DB in RDS.
First thing is that to install mysql-client and try that again. There can be several issues if it doesn't work even after trying to connect with mysql-client and consider those as well.
The state of the RDS instance should be 'available'. Otherwise it won't connect to any.
Check whether your EC2 instance IAM role has the permission which needs to access RDS instance. If your IAM role doesn't have permission then it won't get permission to connect and it will timeout after a while.
*It's better if you can post some code here.

I'm having a bit of an issue with connecting to my Amamzon RDS (Mysql) instance through a fresh Lumen installation on an Amazon EC2 instance.
The Lumen installation uses the PDO class.
The problem:
I can't connect to my RDS, I'm simply getting a timeout when trying:
SQLSTATE[HY000] [2002] Connection timed out
What have i tried?
I've tried connecting directly to the ip of my rds instance. Same result.
When debugging my connection, I get a connection string like mysql:host=x.x.x.x;port=3306;dbname=(...) - ip and db are correct. Username and password are also correct when debugging the connection.
Connecting from another server, that is outside Amazon AWS. Also using PDO = negative result
Checking that the RDS is set up to available from the outside = It is, I can connect from my own computer. Tested with two different machines.
Looking through various posts about rds and timeouts = no usable solutions
Connected directly to the ip of my RDS instance = negative result
When developing on my local machine, I'm not having any problems connecting to the same rds.
Anything else you should know?
When connecting from my computers (using Sequel Pro), i can connect - I've tried from two computers, both with positive result. This is indifferent if i use the domain/endpoint of the rds instance or connect directly to the ip.
By my own logic, I should be ablet to connect from any EC2 instance, since I can connect from my own computer.
Any help would be appriciated.
Did you actually give the right permission inbound to RDS from that EC2 Instance?
You need to modify your security group to give access.
I am very new to Amazon Web Services, I have created Mysql DB on RDS and stored some data.
Now i want to connect to RDS db from localhost(which is in running on my desktop) ,Tried as fallow in my PHP connection.
$con = mysql_connect("XXXX.XXXXX.XX-XX-X.rds.amazonaws.com:3306", "XXX", "XXX");
But getting error as fallows
Could not connect: Can't connect to MySQL server on 'awsniti.XXXX.rds.amazonaws.com'
Also tried giving my local IP address to Inbounds of Security Group. But couldn't connect.
googled a lot, but not able to find right answer.
Please help me with this issue.
Adding the internet IP of your local network/machine on the security group associated with your RDS database should work. But I prefer to create a SSH tunnel through a server that I already gave access to the database. This way you don't have to care about the security group configuration every time you need to connect from a different IP address.
If you are on Linux or OSX you can run locally
ssh -f user#your-web-server.com -L 3306:XXXX.XXXXX.XX-XX-X.rds.amazonaws.com:3306 -N and then connect localhost:3306 from PHP to access the RDS database. If you are on Windows it's also possible to create a tunnel using Putty (http://bit.ly/1GQmaYo)
I am using Amazon EC2 with Amazon RDS.
I have successfully created database and uploaded code to amazon using Elastic Beanstalk.
Now I want to import my local databse data to RDS databse. I surf and found that by mysql command we can do that so I do this
D:\wamp\bin\mysql\mysql5.5.8\bin>mysql --host=myinstances.aa23swersdf.us-east-1.rds.amazonaws.com --user=username --pass=password --port=3306 dbname < locahost.sql
But it throws this error :
ERROR 2003 (HY000): Can't connect to MySQL server on 'myinstances.aa23swersdf.us-east-1.rds.amazonaws.com' (10060)
How can I solve it?
I have do this by cmd on windows.
Hope this helps.
Make sure port 3306 is allowed on the Amazon EC2 Instance firewall.
Add security group that allows port 3306
On the mysql of both local and amazon, add the host myinstances.aa23swersdf.us-east-1.rds.amazonaws.com with your corresponding username and password.
Flush privileges.
You can also used MySQL Connector to test. It is available to download at the Internet.
Have you added your IP Address to the security group.
Or you can install phpMyAdmin on one of the AWS instances, assign it to the security group and then run the import.
Not sure if what I am attempting to do is possible or not. I just launched my very first EC2 instance running Ubuntu 12.04 and successfully installed Laravel 4. I have the database working just fine on the EC2 instance and I am able to connect to it with MySQL Workbench on my local machine using a .pem SSH key.
I will be using EC2 to handle certain aspects of a product that I am developing to ensure improved reliability - client side users will be interacting with this primarily through CURL. I want to be able to have my non-EC2 website, also running Laravel 4, use the MySQL database that I set up on my EC2 instance.
I tried changing my app/config/database.php file to include the EC2 instance IP address and MySQL credentials, when Laravel attempts to connect it returns a timeout error.
I modified my.cfn and commented out bind-address = 127.0.0.1, I do not seem to have the skip-network that I have seen mentioned. Still no joy.
Any suggestions?
In side MySQL (PhpMyAdmin if you installed it) -> Users overview -> Edit your user with Host is
%
That is mean, you can connect to MySQL in anywhere with command
mysql_connect($IpOfYourHost, $UserAbove, $Password)
Maybe this helps you. :)
Resolved
I changed bind-address to 0.0.0.0, created a new MySQL user - 'user'#'%', and had my host whitelist the IP. Done!
I have an amazon EC2 instance (redhat linux ) and a RDS (mysql 5.5 ). After stop /start EC2 instance. EC2's ip was changed and cannt connect RDS anymore. I can successfully connect RDS instance from command line. However, it is unable to connect from php script and give me this warning.
PHP Warning: mysqli::mysqli(): (HY000/2003): Can't connect to MySQL server on 'applicantdb.xr3x2xcale.eu-west-1.rds' (13)
It is working fine from my localhost and I can connect to localhost. It is really annoying and if somebody knows the solution. Please help me and I do really appreciate it.
Thanks layke , the problem solved
The solution was
It restricts Apache remote database connection as default. So our scripts work in command line (# php sqltest.php), and mysql can connect to server but when Apache is involved (calling a php script as web page) then it doesn't work.
Setting:
setsebool -P httpd_can_network_connect=1
You need to in your RDS Security group make sure that your Amazon EC2 security profile has access.
