Deploy Symfony app to AWS with MySQL - mysql

Question

I have a web application running on AWS, as well as a MySQL database instance. I have set up my local environment to run the symfony app and connect to the aws db instance just fine. When trying to deploy, everything was fine until I added the MySQL stuff. Now, when I deploy, composer install hook fails, and I'm left with this output:
i-04b06d321dedd2a9c Severe 1 hour 8 - - - - - - - - - - 0.00 0.01 0.1 0.0 99.9 0.0
Application deployment failed at 2016-06-22T13:51:22Z with exit status 1 and error: Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/10_composer_install.sh failed.

Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted

Incorrect application version "app-b659-160621_222635" (deployment 8). Expected version "which-lineup-1" (deployment 13).
Interestingly enough, I don't even have a composer.* file in this particular zip file that I uploaded. So I'm a little confused as to how it even thinks that. I thought my problem was not having the correct values set up for my DB connection. However, I added environment variables to my environment configuration with the naming scheme SYMFONY__ENV__MYSQL__SERVER, etc...
Here is my parameters.yml.dist file:
# This file is a "template" of what your parameters.yml file should look like
# Set parameters here that may be different on each deployment target of the app, e.g. development, staging, production.
# http://symfony.com/doc/current/best_practices/configuration.html#infrastructure-related-configuration
parameters:
database_host: %env.mysql.server%
database_port: %env.mysql.port%
database_name: %env.mysql.database%
database_user: %env.mysql.username%
database_password: %env.mysql.password%
Any help is greatly appreciated.

Answer 1

The problem was that my web application instance did not have access (via security groups) to my database instance. How I fixed it, was very basic. I deleted the current database instance, and created a new one from Web Application Console -> Configuration -> Data Tier. I then rebuilt the environment, and it seems to be working now.
