Environment variables and PHP

Question

I have an ubuntu server with a handful of custom environment variables set in /etc/environment as per the ubuntu community recommendation

When I use php from the com

Answer 1

The problem is when you run the php-fpm. The process not load the environment.
You can load it in the startup script.
My php-fpm is install by apt-get.
So modify the

/etc/init.d/php5-fpm

and add (beware the space between the dot and the slash)

. /etc/profile

and modify the /etc/profile to add

. /home/user/env.sh

In the env.sh. You can export the environment whatever you need.

Then modify

php-fpm.conf

add env[MY_ENV_VAR_1] = 'value1' under the [www] section.
Last. restart the php-fpm. You'll get the environment load by the fpm.

Answer 2

Adding on to the answers above, I was running php-fpm7 and nginx in an alpine:3.8 docker container. The problem that I faced was the env variables of USER myuser was not getting copied into the USER root

My entrypoint for docker was

sudo nginx  # Runs nginx as daemon
sudo php-fpm7 -F -O  # Runs php-fpm7 in foreground

The solution for this was

sudo -E nginx
sudo -E php-fpm7 -F -O

-E option of sudo copies all env variables of current user to the root

Of course, your php-fpm.d/www.conf file should have clear_env=no

And FYI, if you're using a daemon service like supervisord they have their own settings to copy the env. For example, supervisord has setting called copy_env=True

1. Setting environment variables automatically in php-fpm.conf

clear_env = no

2. Setting environment variables manually in php-fpm.conf

env[MY_ENV_VAR_1] = 'value1'
env[MY_ENV_VAR_2] = 'value2'

! Both methods are described in php-fpm.conf:

Clear environment in FPM workers Prevents arbitrary environment variables from reaching FPM worker processes by clearing the environment in workers before env vars specified in this pool configuration are added. Setting to "no" will make all environment variables available to PHP code via getenv(), $_ENV and $_SERVER. Default Value: yes

clear_env = no

Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from the current environment. Default Value: clean env

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

I found solution in this github discussion .

Answer 4

It turns out that you have to explicitly set the ENV vars in the php-fpm.conf

Here's an example:

[global]
pid = /var/run/php5-fpm.pid
error_log = /var/log/php5-fpm.log

[www]
user = www-data
group = www-data
listen = /var/run/php5-fpm.sock
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /
env[MY_ENV_VAR_1] = 'value1'
env[MY_ENV_VAR_2] = 'value2'
