Configuration Parameters
========================
How do I override application variables?
----------------------------------------
There are few settings that can't be changed by the user interface.
These parameters are defined with PHP constants.
To override them, rename the file `config.default.php` to `config.php`.

Database configuration
----------------------
By default, Miniflux uses Sqlite but Postgres is also supported.
### Sqlite configuration
You could change the default location of the Sqlite file by changing the default values:
```php
define('DB_DRIVER', 'sqlite');
define('DB_FILENAME', DATA_DIRECTORY.'/db.sqlite');
```
### Postgres configuration
Miniflux will creates the schema automatically but not the database itself:
```sql
CREATE DATABASE miniflux;
```
The `config.php` have to be modified as well:

```php
2016-12-27 00:01:46 +01:00
define('DB_DRIVER', 'postgres');
// Replace these values:
define('DB_HOSTNAME', 'localhost');
define('DB_NAME', 'miniflux');
define('DB_USERNAME', 'my postgres user');
define('DB_PASSWORD', 'my secret password');
```
List of parameters

Actually, the following constants can be overridden:
