一、配置文件位置
- /usr/local/opt/grafana/share/grafana/default.ini
- /usr/local/etc/grafana/grafana.ini
二、init格式
1、注释：
- 以";"开头，不管多长或多短，独占一行
三、配置文件调用顺序
1、grafana启动时，首先会调用/usr/local/opt/grafana/share/grafana/default.ini（定义了默认的启动信息）
2、之后会调用我们写的--config所指向的配置文件（默认为/usr/local/etc/grafana/grafana.ini）,所以通过该文件我们可以覆盖default.ini的配置。
四、完整文件及注释
