Setting environement variable for Symfony Nginx/PHP-FPM
The Symfony documentation gives a basic configuration available here:
http://symfony.com/doc/current/cookbook/configuration/web_server_configuration.html#nginx
Nginx configuration
Below is server block configuration taken from the Symfony documentation which just one addition to pass some environment variables to Symfony application :
server {
server_name domain.tld www.domain.tld;
root /var/www/project/web;
location / {
# try to serve file directly, fallback to rewrite
try_files $uri @rewriteapp;
}
location @rewriteapp {
# rewrite all to app.php
rewrite ^(.*)$ /app.php/1ドル last;
}
location ~ ^/(app|app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
# now the interesting part
fastcgi_param SYMFONY__MY__VARIABLE 'my variable';
}
error_log /var/log/nginx/project_error.log;
access_log /var/log/nginx/project_access.log;
}The interesting part as mention in the configuration is that you can forward some value using a custom name.
The variable mapping
The schema must be SYMFONY__NAME, where NAME can have some double underscores as separator.
NAME will translate to %name% variable in symfony, where double underscores will be replaced by a dot.
-
SYMFONY__VARIABLE-> %variable% -
SYMFONY__MY__VARIABLE-> %my.variable%
Symfony configuration
Now in the symfony project available at /var/www/project/ you will any configuration file you where you may need the content of some environment variable.
Pretend I need the content of SYMFONY__MY__VARIABLE in the variable nothing_to_do in app/config/parameters.(yaml|php|xml|ini). It's your choice about the format.
I will use a yaml as it is easier to type:
# app/config/config.yaml
[...]
parameters:
nothing_to_do: %my.variable%
[...]See the documentation about external variable configuration which does not cover Nginx:
http://symfony.com/doc/current/cookbook/configuration/external_parameters.html#environment-variables
As you may see it's quite simple but powerful.
