环境变量和 PHP
我有一个 ubuntu 服务器，根据 ubuntu 社区推荐
I have an ubuntu server with a handful of custom environment variables set in /etc/environment as per the ubuntu community recommendation
当我从命令行使用 php 时，我可以使用 php 的 getenv() 函数来访问这些变量.
When I use php from the command line I can use php's getenv() function to access this variables.
另外，如果我从命令行运行 phpinfo()，我会在 ENVIRONMENT 部分看到我的所有变量.
Also, if I run phpinfo() from the command line I see all of my variables in the ENVIRONMENT section.
但是，当尝试访问由 php5-fpm 运行的进程内的相同数据时，此数据不可用.我可以在 phpinfo() 的 ENVIRONMENT 部分看到的是:
However, when trying to access the same data inside processes being run by php5-fpm this data is not available. All I can see in the ENVIRONMENT section of phpinfo() is:
USER www-data
HOME /var/www
我知道命令行使用这个ini:
I know the command line uses this ini:
/etc/php5/cli/php.ini
而fpm使用:
/etc/php5/fpm/php.ini
我没有设法找到两者之间的任何差异，这可以解释为什么 ENV 变量在两者中都没有出现.
I've not managed to find any differences between the two that would explain why the ENV variables are not coming through in both.
如果运行:
sudo su www-data
然后回显我期望它们确实可供 www-data 用户使用的环境变量.
and then echo the environment variables I am expecting they are indeed available to the www-data user.
我需要怎么做才能让我的环境变量进入 fpm 运行的 php 进程?
What do I need to do to get my environment variables into the php processes run by fpm?
推荐答案
原来你必须在 php-fpm.conf 中显式设置 ENV vars
It turns out that you have to explicitly set the ENV vars in the php-fpm.conf
这是一个例子:
[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'
