Checkout the [configuration](/installation/configuration) page for more information about what you can configure in `grafana.ini`
### Config file locations
- Default configuration from `$WORKING_DIR/conf/defaults.ini`
- Custom configuration from `$WORKING_DIR/conf/custom.ini`
- The custom configuration file path can be overridden using the `--config` parameter
> **Note.** If you have installed Grafana using the `deb` or `rpm`
> packages, then your configuration file is located at
> `/etc/grafana/grafana.ini`. This path is specified in the Grafana
> init.d script using `--config` file parameter.
### Using environment variables
All options in the configuration file (listed below) can be overridden
using environment variables using the syntax:
```bash
GF_<SectionName>_<KeyName>
```
Where the section name is the text within the brackets. Everything
should be upper case, `.` should be replaced by `_`. For example, given these configuration settings:
```bash
# default section
instance_name =${HOSTNAME}
[security]
admin_user = admin
[auth.google]
client_secret = 0ldS3cretKey
```
Then you can override them using:
```bash
export GF_DEFAULT_INSTANCE_NAME=my-instance
export GF_SECURITY_ADMIN_USER=true
export GF_AUTH_GOOGLE_CLIENT_SECRET=newS3cretKey
```

## Configuration management tools
Currently we do not provide any scripts/manifests for configuring Grafana. Rather then spending time learning and creating scripts/manifests for each tool, we think our time is better spent making Grafana easier to provision. Therefor, we heavily relay on the expertise of he community.
