I have an application that has been developed with Codeigniter. It uses an SQL Server database, hosted in an Amazon RDS Instance.
The application is using the mssql driver (I can't change it to sqlsrv, unfortunately).
The RDS instance is ok, I tried connecting to the database from an SQL Server client, and everything works perfect, but when I try to connect it in the CI application, I get the classic "Unable to connect to your database server using the provided settings." error.
Is there a way to have a more descriptive error thrown by CI? I have lost a lot of time trying to solve this issue and I really don't know what else I should look.
Notes:
This was working fine some days ago. I had to make a copy of the CI app (which is hosted on an Amazon EC2 instance). I shared the AMI to a different AWS account, and created a new instance with it, but didn't change anything in the volume. Everything has been exactly copied from one place to the other.
Php info tells me that the mssql driver is there and it is correct.
The Security Groups in the RDS instance and the EC2 instance, are open to the world (I deleted all the restrictions in order to see if that was the problem)
I will really appreciate any kind of help.

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 created multiple REST api's for my website on a local server(wamp) and now i am trying to move it to a online server(aws elastic beanstalk). My question is where do i build my database with the tables and rows etc just like in phpmyadmin? I figured that "upload and deploy" means upload the php file i made but when i do i get an error saying "health degraded". So what i want to do is basically move my local server to an online one with aws EB. I watched a bunch of videos and did a lot of research but can't seem to find the way to go about this problem.

You can connect to the RDS instance created by beanstalk using a Database Management Client Tool like MySQL Workbench, Heidi SQL & etc using the DNS name, created for RDS instance. However one challenge you will face is to access the RDS instance from your client machine, since its not a good practice to make the Database publicly accessible. You can create a EC2 instance (Windows or Linux with GUI) inside the same VPC, connect to it (Remote Desktop or SSH) and install the tools so that you can use the tools inside the server, to connect to the RDS instance.

To understand the structure in code inside the Zip file, I would recommend to create a Beanstalk environment with a sample project available in Beanstalk and download the sample project artifact (Zip file) from S3 so that you can compare the project structure requirements.
If you prefer to go through the documentation, you can refer this. If nothing goes well, connect to the ElasticBeanstalk provisioned EC2 instance (Either using Remote Desktop for Windows or SSH to linux) and investigate the deployed artifacts.
I need some major help in setting up my android app to add/receive data to/from my database. I'm using Amazon's RDS service in connection with xampp's phpMyAdmin. I've already successfully connected my DB instance to the database in phpMyAdmin. Also, I've written my php scripts to do basic CRUD (Create, Read, Update, Delete) commands in SQL. I've been following this tutorial.
The problem for me is, in his tutorial he is using strings like this:
private static String url_all_products = "http://api.androidhive.info/android_connect/get_all_products.php";
to run his php scripts in a call to makeHttpRequest(url_all_products). But I don't have my own website to do this and I'm pretty sure I don't need one to do this.
Next, I have a test.php file that does a simple echo statement and it works when I run this in a web browser:
http://localhost/phpfiles/test.php
Which leads me to my second problem. I don't want to use localhost because I need these php files and the ability to retrieve data from the database to be accessible to anyone using my app. This is the sole reason I'm using Amazon's RDS service so my database can be accessed on the cloud.
So how can I use the host address provided to me by Amazon RDS to access the database and where do I store all the php files so I can properly use them in Android the way the tutorial shows? They are currently saved in xampp/htdocs/phpfiles/.
I feel like I'm missing some fundamental understanding of all this and I'm going about it all wrong. If someone can point me in the right direction that would make my day.
It sounds like you don't really need the XAMPP install on your local machine at all. You're hosting this on Amazon and you want it to be available to the internet, so your local computer isn't involved. You can use XAMPP locally for testing and development, but for production use you'll be exclusively on the Amazon RDS cloud.
But I don't have my own website to do this and I'm pretty sure I don't need one to do this.
You may not want a website, but you do want your services hosted on the internet. That's what your RDS instance is for, and technically the tutorial is referring to an API which happens to be exposed through a web page. This is a much better idea than opening MySQL directly to the internet on port 3306.
You'll then use your Amazon host — for which you really should use a FQDN such as api.example.com rather than the IP address, but the IP address will work just fine from a technical aspect.
The files you refer to are on your local XAMPP installation; in the xampp/htdocs/phpfiles/ folder, and need to instead be on the RDS instance.
Then your application accesses the API you expose in those files which return information back to your application.
I have a site remotely hosted away from the Google Cloud SQL instance. I have set up and authorised CIDR range for this. I am using PHP (PDO) to connect to the Google Cloud SQL instance with an application built on the Laravel 5 framework. The website itself is deployed on Windows Azure, I do not have a choice about this stack.
My problem is on probably about 10% of page loads I receive the error:
SQLSTATE[HY000] [2006] MySQL server has gone away
While trying to set up the CIDR for this in the developer console (getting my Azure IP and converting it to a range) I had this problem 100% of the time, so it's possible that it's related to IP authorisation, however why would this work 80-90% of the time, and deny the application sporadically?
Any help would be much appreciated.
go to the cloud sql instance you created. Under properties you will see "authorized applications" click manage and add the project id of your project to it. hope that works for you
I know this is old, but in case someone else ran into similar problems like I did, this might help...
Check your system clock, make sure it's not behind (happened to me with a local docker instance)
Check your credentials to make sure they're correct and match up with the instance you're trying to connect to.
Good luck
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!
