# 基于环境变量进行配置文件切换
配置之所以从代码中提取出来,就是为了更好适应变化。通常我们的应用都有开发环境、生产环境等不同运行环境,这些环境下应用的一些配置肯定会有不同,比如:配置中心的地址等。
如果把所有环境的配置都放在同一个文件里,非常不好管理,我们接到新需求后,在开发环境进行开发时,需要将配置文件中的参数都改成开发环境的,提交代码时还要改回去,这样改来改去非常容易出错。
上述问题的解决办法就是通过环境变量来区分当前运行环境并通过环境变量来切换不同配置文件。APISIX 中对应的环境变量就是:`APISIX_PROFILE`。
在没有设置`APISIX_PROFILE` 时,默认使用以下三个配置文件:
* conf/config.yaml
* conf/apisix.yaml
* conf/debug.yaml
如果设置了`APISIX_PROFILE`的值为`prod`,则使用以下三个配置文件:
* conf/config-prod.yaml
* conf/apisix-prod.yaml
* conf/debug-prod.yaml
通过这种方式虽然会增加配置文件的数量但可以独立管理再配置git等版本管理工具还能更好实现版本管理。
