Setting Nginx Environment variablesInstructions

Set current environment variable to dev

Fastcgi_param runtime_enviroment ' DEV '

Database account password

Fastcgi_param mysql_username ' root ' fastcgi_param mysql_password ' root '

Configuration file format

Configuring in the Fastcgi_params file

Fastcgi_param runtime_enviroment ' DEV '; fastcgi_param mysql_username ' root '; Fastcgi_param mysql_password ' root ';

Configuring in Nginx.conf

server {    listen   ;     root/var/www;    Index index.php;    server_name localhost;    Location/    {            index index.php;    }             Location ~. *\. (PHP|PHP5) $ {        Fastcgi_pass 127.0.0.1:9000;        Fastcgi_index index.php;        Include Fastcgi_params;    }   }

Setting environment variables for PHP scriptsTemporarily set for the current user

Temporary settings only need to be performed

Export Key=value

Permanently set for the current user

Written in ~/.BASHRC (different systems vary)

Set for all users (not including root)

Create File/etc/profile.d/test.sh, write

Key=value

Set for all users (including root)

Write in/etc/environment

Key=value

Note that this file's effective time is when the user logs in, so for root, the machine needs to be restarted

Set in supervisor

Sometimes PHP scripts are controlled with supervisor, so remember to set the environment in the supervisor configuration

Invoking server environment variables in PHP

There are two ways to call in PHP:

$env = getenv (' runtime_enviroment ');

There are also hyper-global variable modes:

$env = $_server[' runtime_enviroment ');
