Laravel 5.2获得Linux系统环境变量。

Is there a possibility to get some Linux system environment variables and still use the .env variables?

是否有可能获得一些Linux系统环境变量并仍然使用.env变量?

We want to use an auto-generated database password that's set as Linux environment variable but can't get Laravel to find the Linux system environment variables.

我们希望使用一个自动生成的数据库密码，该密码设置为Linux环境变量，但不能让Laravel找到Linux系统环境变量。

Linux system variables cannot be access through PHP/Apache. You could set a variable in the Apache Vhost of your site via SetEnv and grab it in Laravel.

不能通过PHP/Apache访问Linux系统变量。您可以通过SetEnv在站点的Apache Vhost中设置一个变量，并在Laravel中获取它。

You could do

你可以做

Apache: SetEnv DB_Pass dbpassword123 in your Vhost
Apache:在Vhost中SetEnv DB_Pass dbpassword123
Nginx: fastcgi_param DB_Pass dbpassword123
Nginx:fastcgi_param DB_Pass dbpassword123

Example Apache Vhost:

示例Apache Vhost:

<VirtualHost example.com:80>
    ServerAdmin root@mpj.local.dev
    DocumentRoot /var/www/html
    ServerName mpj.local.dev

    SetEnv DB_Pass dbpassword123

    <Directory /var/www/html>
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog "/var/log/apache2/error_log"
    CustomLog "/var/log/apache2/access_log" common
</VirtualHost>

and fetch the variable DB_Pass in Laravel with

在Laravel中获取变量DB_Pass

$dbPass = env('DB_Pass');
