Environment configuration as provided by Symfony is enhanced in = eZ Platform to allow specifying this in the virtual host configuration.
= You can configure several environments, from production, development or sta= ging, even if for each one of them you need to use different configuration = sets.

Web server configuratio= n

For example, using Apache, in the VirtualHost example in doc/apache2/ in your insta= ll, the required VirtualHost configurations have been already = included. You can switch to the desired environment by setting the EN= VIRONMENT environment variable to "prod", "dev" or other custom value, as you can see in the following example:



=20
# Environment.
# Possible values: "prod" and "dev" out-of-the-box, other values possible w=
ith proper configuration
# Defaults to "prod" if omitted (uses SetEnvIf so value can be used in rewr=
ite rules)
SetEnvIf Request_URI ".*" SYMFONY_ENV=3D"prod"=20


Configuration
If you want to use a custom environment (something else then "prod=
" and "dev") the next step is to create the dedicated c=
onfiguration files for your environment:

app/config/config_<env_name>.yml<=
/code>

app/config/ezplatform_<env_name>.=
yml

The name used as <env_name>=
 will be the one that can be used as value of the ENVIRONMENT =
environment variable.
Those files must import the main configuration file, just like the defau=
lt config_dev.yml already does. Here's an example:

=20
imports:
    - { resource: config.yml }=20


This allows you to override settings defined in the main configuration f=
ile, depending on your environment (like the DB settings or any other setti=
ng you may want to override).
