# Configuration
The Grafana back-end has a number of configuration options that can be
specified in a `.ini` configuration file or specified using environment variables.
## 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:
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:
[security]
admin_user = admin
[auth.google]
client_secret = 0ldS3cretKey
Then you can override them using:
export GF_SECURITY_ADMIN_USER=true
export GF_AUTH_GOOGLE_CLIENT_SECRET=newS3cretKey
<hr />
## [paths]
### data
Path to where Grafana stores the sqlite3 database (if used), file based
sessions (if used), and other data. This path is usually specified via
command line in the init.d script or the systemd service file.
### logs
Path to where Grafana will store logs. This path is usually specified via
command line in the init.d script or the systemd service file. It can
be overridden in the configuration file or in the default environment variable
file.
## [server]
### http_addr
The IP address to bind to. If empty will bind to all interfaces
### http_port
The port to bind to, defaults to `3000`. To use port 80 you need to
either give the Grafana binary permission for example:
$ sudo setcap 'cap_net_bind_service=+ep' /opt/grafana/current/grafana
Or redirect port 80 to the Grafana port using:
$ sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000
Another way is put a webserver like Nginx or Apache in front of Grafana and have them proxy requests to Grafana.
### protocol
`http` or `https`
### domain
This setting is only used in as a part of the `root_url` setting (see below). Important if you
use GitHub or Google OAuth.
### enforce_domain
Redirect to correct domain if host header does not match domain.
Prevents DNS rebinding attacks. Default is false.
### root_url
This is the full URL used to access Grafana from a web browser. This is
important if you use Google or GitHub OAuth authentication (for the
callback URL to be correct).
> **Note** This setting is also important if you have a reverse proxy
> in front of Grafana that exposes it through a subpath. In that
> case add the subpath to the end of this URL setting.
### static_root_path
The path to the directory where the front end files (HTML, JS, and CSS
files). Default to `public` which is why the Grafana binary needs to be
executed with working directory set to the installation path.
### cert_file
Path to the certificate file (if `protocol` is set to `https`).
### cert_key
Path to the certificate key file (if `protocol` is set to `https`).
<hr />
<hr />
## [database]
Grafana needs a database to store users and dashboards (and other
things). By default it is configured to use `sqlite3` which is an
embedded database (included in the main Grafana binary).
### type
Either `mysql`, `postgres` or `sqlite3`, it's your choice.
### path
Only applicable for `sqlite3` database. The file path where the database
will be stored.
### host
Only applicable to MySQL or Postgres. Includes IP or hostname and port.
For example, for MySQL running on the same host as Grafana: `host =
127.0.0.1:3306`
### name
The name of the Grafana database. Leave it set to `grafana` or some
other name.
### user
The database user (not applicable for `sqlite3`).
### password
The database user's password (not applicable for `sqlite3`).
### ssl_mode
For `postgres` only, either `disable`, `require` or `verify-full`.
<hr />
## [security]
### admin_user
The name of the default Grafana admin user (who has full permissions).
Defaults to `admin`.
### admin_password
The password of the default Grafana admin. Defaults to `admin`.
### login_remember_days
The number of days the keep me logged in / remember me cookie lasts.
### secret_key
Used for signing keep me logged in / remember me cookies.
### disable_gravatar
Set to `true` to disable the use of Gravatar for user profile images.
Default is `false`.
<hr />
## [users]
### allow_sign_up
Set to `false` to prohibit users from being able to sign up / create
user accounts. Defaults to `true`. The admin user can still create
users from the [Grafana Admin Pages](../reference/admin.md)
### allow_org_create
Set to `false` to prohibit users from creating new organizations.
Defaults to `true`.
### auto_assign_org
Set to `true` to automatically add new users to the main organization
(id 1). When set to `false`, new users will automatically cause a new
organization to be created for that new user.
### auto_assign_org_role
The role new users will be assigned for the main organization (if the
above setting is set to true). Defaults to `Viewer`, other valid
options are `Admin` and `Editor`.
<hr>
## [auth.anonymous]
### enabled
Set to `true` to enable anonymous access. Defaults to `false`
### org_name
Set the organization name that should be used for anonymous users. If
you change your organization name in the Grafana UI this setting needs
to be updated to match the new name.
### org_role
Specify role for anonymous users. Defaults to `Viewer`, other valid
options are `Editor` and `Admin`.
## [auth.github]
You need to create a GitHub application (you find this under the GitHub
profile page). When you create the application you will need to specify
a callback URL. Specify this as callback:
http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/github
This callback URL must match the full HTTP address that you use in your
browser to access Grafana, but with the prefix path of `/login/github`.
When the GitHub application is created you will get a Client ID and a
Client Secret. Specify these in the Grafana configuration file. For
example:
[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
allow_sign_up = false
team_ids =
Restart the Grafana back-end. You should now see a GitHub login button
on the login page. You can now login or sign up with your GitHub
accounts.
You may allow users to sign-up via GitHub authentication by setting the
`allow_sign_up` option to `true`. When this option is set to `true`, any
user successfully authenticating via GitHub authentication will be
automatically signed up.
### team_ids
Require an active team membership for at least one of the given teams on
GitHub. If the authenticated user isn't a member of at least one of the
teams they will not be able to register or authenticate with your
Grafana instance. For example:
[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email,read:org
team_ids = 150,300
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
allow_sign_up = false
<hr>
## [auth.google]
You need to create a Google project. You can do this in the [Google
Developer Console](https://console.developers.google.com/project). When
you create the project you will need to specify a callback URL. Specify
this as callback:
http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/google
This callback URL must match the full HTTP address that you use in your
browser to access Grafana, but with the prefix path of `/login/google`.
When the Google project is created you will get a Client ID and a Client
Secret. Specify these in the Grafana configuration file. For example:
[auth.google]
enabled = true
client_id = YOUR_GOOGLE_APP_CLIENT_ID
client_secret = YOUR_GOOGLE_APP_CLIENT_SECRET
scopes = https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
auth_url = https://accounts.google.com/o/oauth2/auth
token_url = https://accounts.google.com/o/oauth2/token
allowed_domains = mycompany.com mycompany.org
allow_sign_up = false
Restart the Grafana back-end. You should now see a Google login button
on the login page. You can now login or sign up with your Google
accounts. The `allowed_domains` option is optional, and domains were separated by space.
You may allow users to sign-up via Google authentication by setting the
`allow_sign_up` option to `true`. When this option is set to `true`, any
user successfully authenticating via Google authentication will be
automatically signed up.
<hr>
## [auth.basic]
### enabled
When enabled is `true` (default) the http api will accept basic authentication.
<hr>
## [auth.ldap]
### enabled
Set to `true` to enable LDAP integration (default: `false`)
### config_file
Path to the LDAP specific configuration file (default: `/etc/grafana/ldap.toml`)
> For details on LDAP Configuration, go to the [LDAP Integration](ldap.md) page.
<hr>
## [auth.proxy]
This feature allows you to handle authentication in a http reverse proxy.
### enabled
Defaults to `false`
### header_name
Defaults to X-WEBAUTH-USER
#### header_property
Defaults to username but can also be set to email
### auto_sign_up
Set to `true` to enable auto sign up of users who do not exist in Grafana DB. Defaults to `true`.
<hr>
## [session]
### provider
Valid values are `memory`, `file`, `mysql`, `postgres`. Default is `file`.
### provider_config
This option should be configured differently depending on what type of
session provider you have configured.
- **file:** session file path, e.g. `data/sessions`
- **mysql:** go-sql-driver/mysql dsn config string, e.g. `user:password@tcp(127.0.0.1:3306)/database_name`
- **postgres:** ex: user=a password=b host=localhost port=5432 dbname=c sslmode=disable
If you use MySQL or Postgres as the session store you need to create the
session table manually.
Mysql Example:
CREATE TABLE `session` (
`key` CHAR(16) NOT NULL,
`data` BLOB,
`expiry` INT(11) UNSIGNED NOT NULL,
PRIMARY KEY (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
### cookie_name
The name of the Grafana session cookie.
### cookie_secure
Set to true if you host Grafana behind HTTPS only. Defaults to `false`.
### session_life_time
How long sessions lasts in seconds. Defaults to `86400` (24 hours).
<hr />
## [analytics]
### reporting_enabled
When enabled Grafana will send anonymous usage statistics to
`stats.grafana.org`. No IP addresses are being tracked, only simple counters to
track running instances, versions, dashboard & error counts. It is very helpful
to us, so please leave this enabled. Counters are sent every 24 hours. Default
value is `true`.
### google_analytics_ua_id
If you want to track Grafana usage via Google analytics specify *your* Universal
Analytics ID here. By default this feature is disabled.
<hr />
## [dashboards.json]
If you have a system that automatically builds dashboards as json files you can enable this feature to have the
Grafana backend index those json dashboards which will make them appear in regular dashboard search.
### enabled
`true` or `false`. Is disabled by default.
### path
The full path to a directory containing your json dashboards.
