附12 grafana配置文件

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

 ##################### Grafana Configuration Example #####################
 # use "--config" to specified via command line
 # Everything has defaults so you only need to uncomment（解开注释，去掉";"） things you want to
 # change
 
 # possible values : production, development
 app_mode = production
 
 # grafana-server instance name, defaults to HOSTNAME environment variable value or hostname if HOSTNAME var is empty
 # Used in logging and internal metrics and in clustering info

 #
 # Directory where grafana can store logs
 # use "cfg:default.paths.logs" to specified via command line
 logs = /usr/local/var/log/grafana

所以，上边的admin_user=zhaojigang admin_password=zhaojigang如果不是第一次启动之前设置的，那么就是不起作用的
