设置环境变量常见的地方为区分开发环境/生产环境,或者定义一些数据库的帐号密码

设置Apache环境变量

指令

设置当前环境变量为DEV

<code>SetEnv RUNTIME_ENVIROMENT DEV
</code>
Copy after login

数据库帐号密码

<code>SetEnv MYSQL_USERNAME root
SetEnv MYSQL_PASSWORD root
</code>
Copy after login

配置文件格式

<code><virtualhost>
    ServerAdmin admin@admin.com
    DocumentRoot "/var/www/"
    ServerName localhost
    SetEnv RUNTIME_ENVIROMENT DEV
    SetEnv MYSQL_USERNAME root
    SetEnv MYSQL_PASSWORD root
    ErrorLog "logs/error.log"
    CustomLog "logs/access.log" common
</virtualhost>
</code>
Copy after login

设置Nginx环境变量

指令

设置当前环境变量为DEV

<code>fastcgi_param RUNTIME_ENVIROMENT 'DEV'
</code>
Copy after login

数据库帐号密码

<code>fastcgi_param MYSQL_USERNAME 'root'
fastcgi_param MYSQL_PASSWORD 'root'
</code>
Copy after login

配置文件格式

在fastcgi_params文件中配置

<code>fastcgi_param RUNTIME_ENVIROMENT 'DEV';
fastcgi_param MYSQL_USERNAME 'root';
fastcgi_param MYSQL_PASSWORD 'root';   
</code>
Copy after login

在nginx.conf中配置

<code>server {
    listen   80; 
    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;
    }   
}
</code>
Copy after login

为PHP脚本设置环境变量

为当前用户临时设置

临时设置只需要执行

<code>export KEY=VALUE
</code>
Copy after login

为当前用户永久设置

~/.bashrc(不同系统各有不同)中写

为所有用户(不包括root)设置

创建文件/etc/profile.d/test.sh,写入

<code>KEY=VALUE
</code>
Copy after login
Copy after login

为所有用户(包括root)设置

/etc/environment中写入

<code>KEY=VALUE
</code>
Copy after login
Copy after login

注意,这个文件的生效时间是用户登录时,所以对于root来说,需要重启机器

在Supervisor中设置

有的时候PHP脚本是用Supervisor来控制的,所以记得设置supervisor配置中的environment项

在PHP中调用服务器环境变量

在PHP中有两个调用方式:

<code>$env = getenv('RUNTIME_ENVIROMENT');
</code>
Copy after login

还有超全局变量方式:

<code>$env = $_SERVER['RUNTIME_ENVIROMENT'];
</code>
Copy after login
