Customize your InfluxDB configuration by using [`influxd`](/v2.0/reference/cli/influxd/)
configuration flags, setting environment variables, or defining configuration
options in a configuration file.

### Configuration precedence
InfluxDB honors configuration settings using the following precedence:

1. `influxd` flags
2. Environment variables
3. Configuration file settings

### InfluxDB configuration file
When `influxd` starts, it checks for a file named `config.*` **in the current working directory**.
The file extension depends on the syntax of the configuration file.
InfluxDB configuration files support the following syntaxes:

- **YAML** (`.yaml`, `.yml`)
- **TOML** (`.toml`)
- **JSON** (`.json`)

To customize the directory path of the configuration file, set the `INFLUXD_CONFIG_PATH`
environment variable to your custom path.

```sh
export INFLUXD_CONFIG_PATH=/path/to/custom/config/directory
```

On startup, `influxd` will check for a `config.*` in the `INFLUXD_CONFIG_PATH` directory.

##### Example configuration file
{{< code-tabs-wrapper >}}
{{% code-tabs %}}
[YAML](#)
[TOML](#)
[JSON](#)
{{% /code-tabs %}}
{{% code-tab-content %}}
```yaml
query-concurrency: 20
query-queue-size: 15
secret-store: vault
session-length: 120
tls-cert: /path/to/influxdb.crt
tls-key: /path/to/influxdb.key
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```toml
query-concurrency = 20
query-queue-size = 15
secret-store = "vault"
session-length = 120
tls-cert = "/path/to/influxdb.crt"
tls-key = "/path/to/influxdb.key"
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```json
{
  "query-concurrency": 20,
  "query-queue-size": 15,

  "tls-key": "/path/to/influxdb.key"
}
```
{{% /code-tab-content %}}
{{< /code-tabs-wrapper >}}

{{% note %}}
Only non-default settings need to be defined in the configuration file.

### session-renew-disabled
Disables automatically extending a user's session TTL on each request.
By default, every request sets the session's expiration time to five minutes from now.
When disabled, sessions expire after the specified [session length](#session-length)
and the user is redirected to the login page, even if recently active.

**Default:** `false`
