# 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.

## Comments In .ini Files

Semicolons (the `;` char) are the standard way to comment out lines in a `.ini` file.

A common problem is forgetting to uncomment a line in the `custom.ini` (or `grafana.ini`) file which causes the configuration option to be ignored.

## 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
```

<hr />

## instance_name

Set the name of the grafana-server instance. Used in logging and internal metrics and in
clustering info. Defaults to: `${HOSTNAME}`, which will be replaced with
environment variable `HOSTNAME`, if that is empty or does not exist Grafana will try to use
system calls to get the machine name.

## [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:

```bash
$ sudo setcap 'cap_net_bind_service=+ep' /usr/sbin/grafana-server
```

Or redirect port 80 to the Grafana port using:

```bash
$ 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`

> **Note** Grafana versions earlier than 3.0 are vulnerable to [POODLE](https://en.wikipedia.org/wiki/POODLE). So we strongly recommend to upgrade to 3.x or use a reverse proxy for ssl termination.

### 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`).

### router_logging

Set to true for Grafana to log all HTTP requests (not just errors). These are logged as Info level events
to grafana log.
<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).

### url

Use either URL or or the other fields below to configure the database
Example: `mysql://user:secret@host:port/database`

### 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`). If the password contains `#` or `;` you have to wrap it with trippel quotes. Ex `"""#password;"""`

### ssl_mode

For Postgres, use either `disable`, `require` or `verify-full`.
For MySQL, use either `true`, `false`, or `skip-verify`.

### ca_cert_path

(MySQL only) The path to the CA certificate to use. On many linux systems, certs can be found in `/etc/ssl/certs`.

### client_key_path

(MySQL only) The path to the client key. Only if server requires client authentication.

### client_cert_path

(MySQL only) The path to the client cert. Only if server requires client authentication.

### server_cert_name

(MySQL only) The common name field of the certificate used by the `mysql` server. Not necessary if `ssl_mode` is set to `skip-verify`.

### max_idle_conn
The maximum number of connections in the idle connection pool.

### max_open_conn
The maximum number of open connections to the database.

<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. Set once on first-run.  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.

### data_source_proxy_whitelist

Define a white list of allowed ips/domains to use in data sources. Format: `ip_or_domain:port` separated by spaces

<hr />

## [users]

### allow_sign_up

Set to `false` to prohibit users from being able to sign up / create
user accounts. Defaults to `false`.  The admin user can still create
users from the [Grafana Admin Pages](../../reference/admin)

### allow_org_create

Set to `false` to prohibit users from creating new organizations.
Defaults to `false`.

### 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` and `Read Only Editor`. e.g. :

`auto_assign_org_role = Read Only Editor`


<hr>

## [auth]

### disable_login_form

Set to true to disable (hide) the login form, useful if you use OAuth, defaults to false.

### disable_signout_menu

Set to true to disable the signout link in the side menu. useful if you use auth.proxy, defaults to false.

<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 OAuth application (you find this under the GitHub
settings page). When you create the application you will need to specify
a callback URL. Specify this as callback:

```bash
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 OAuth application is created you will get a Client ID and a
Client Secret. Specify these in the Grafana configuration file. For
example:

```bash
[auth.github]
enabled = true
allow_sign_up = 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
api_url = https://api.github.com/user
team_ids =
allowed_organizations =
```

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:

```bash
[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 = true
```

### allowed_organizations

Require an active organization membership for at least one of the given
organizations on GitHub. If the authenticated user isn't a member of at least
one of the organizations they will not be able to register or authenticate with
your Grafana instance. For example

```bash
[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email,read:org
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
allow_sign_up = true
# space-delimited organization names
allowed_organizations = github google
```

<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:

```bash
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:

```bash
[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 = true
```

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.

## [auth.generic_oauth]

This option could be used if have your own oauth service.

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/generic_oauth`.

```bash
[auth.generic_oauth]
enabled = true
client_id = YOUR_APP_CLIENT_ID
client_secret = YOUR_APP_CLIENT_SECRET
scopes =
auth_url =
token_url =
api_url =
allowed_domains = mycompany.com mycompany.org
allow_sign_up = true
```

Set api_url to the resource that returns [OpenID UserInfo](https://connect2id.com/products/server/docs/api/userinfo) compatible information.

### Set up oauth2 with Okta

First set up Grafana as an OpenId client "webapplication" in Okta. Then set the Base URIs to `https://<grafana domain>/` and set the Login redirect URIs to `https://<grafana domain>/login/generic_oauth`.

Finaly set up the generic oauth module like this:
```bash
[auth.generic_oauth]
name = Okta
enabled = true
scopes = openid profile email
client_id = <okta application Client ID>
client_secret = <okta application Client Secret>
auth_url = https://<okta domain>/oauth2/v1/authorize
token_url = https://<okta domain>/oauth2/v1/token
api_url = https://<okta domain>/oauth2/v1/userinfo
```

### Set up oauth2 with Bitbucket

```bash
[auth.generic_oauth]
name = BitBucket
enabled = true
allow_sign_up = true
client_id = <client id>
client_secret = <secret>
scopes = account email
auth_url = https://bitbucket.org/site/oauth2/authorize
token_url = https://bitbucket.org/site/oauth2/access_token
api_url = https://api.bitbucket.org/2.0/user
team_ids =
allowed_organizations =
```

<hr>

## [session]

### provider

Valid values are `memory`, `file`, `mysql`, `postgres`, `memcache` or `redis`. 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=verify-full
- **memcache:** ex:  127.0.0.1:11211
- **redis:** ex: `addr=127.0.0.1:6379,pool_size=100,prefix=grafana`

If you use MySQL or Postgres as the session store you need to create the
session table manually.

Mysql Example:

```bash
CREATE TABLE `session` (
    `key`       CHAR(16) NOT NULL,
    `data`      BLOB,
    `expiry`    INT(11) UNSIGNED NOT NULL,
    PRIMARY KEY (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
```

Postgres Example:

```bash
CREATE TABLE session (
    key       CHAR(16) NOT NULL,
    data      BYTEA,
    expiry    INTEGER NOT NULL,
    PRIMARY KEY (key)
);
```
