Config values that can only be set in config/local.config.php
|
|
==========================================================
|
|
|
|
* [Home](help)
|
|
|
|
Friendica's configuration is done in two places: in PHP array configuration files and in the `config` database table.
|
|
Database config values overwrite the same file config values.
|
|
|
|
## File configuration
|
|
|
|
The configuration format for file configuration is an array returned from a PHP file.
|
|
This prevents your webserver from displaying your private configuration. It interprets the configuration files and displays nothing.
|
|
|
|
A typical configuration file looks like this:
|
|
|
|
```php
|
|
<?php
|
|
|
|
/*
|
|
* Comment block
|
|
*/
|
|
|
|
return [
|
|
'section1' => [
|
|
// Comment line
|
|
'key' => 'value',
|
|
],
|
|
'section2' => [
|
|
'array' => ['value0', 'value1', 'value2'],
|
|
],
|
|
];
|
|
```
|
|
|
|
### Configuration location
|
|
|
|
The `config` directory holds key configuration files and can have different config files.
|
|
All of them have to end with `.config.php` and must not include `-sample` in their name.
|
|
|
|
Some examples of common known configuration files:
|
|
- `local.config.php` holds the current node custom configuration.
|
|
- `addon.config.php` is optional and holds the custom configuration for specific addons.
|
|
|
|
Addons can define their own default configuration values in `addon/[addon]/config/[addon].config.php` which is loaded when the addon is activated.
|
|
|
|
If needed, an alternative `config` path can be used by using the `FRIENDICA_CONFIG_DIR` environment variable (full path required!).
|
|
This is useful in case of hardening the system by separating configuration from program binaries.
|
|
|
|
### Static Configuration location
|
|
|
|
The `static` directory holds the codebase default configurations files.
|
|
They must not be changed by users, because they can get changed from release to release.
|
|
|
|
Currently, the following configurations are included:
|
|
- `defaults.config.php` holds the default values for all the configuration keys that can only be set in `local.config.php`.
|
|
- `settings.config.php` holds the default values for some configuration keys that are set through the admin settings page.
|
|
|
|
#### Migrating from .htconfig.php to config/local.config.php
|
|
|
|
The legacy `.htconfig.php` configuration file is still supported, but is deprecated and will be removed in a subsequent Friendica release.
|
|
|
|
The migration is pretty straightforward:
|
|
If you had any addon-specific configuration in your `.htconfig.php`, just copy `config/addon-sample.config.php` to `config/addon.config.php` and move your configuration values.
|
|
Afterwards, copy `config/local-sample.config.php` to `config/local.config.php`, move the remaining configuration values to it according to the following conversion chart, then rename your `.htconfig.php` to check your node is working as expected before deleting it.

### Database Settings
|
|
|
|
The configuration variables database.hostname, database.username, database.password, database.database and database.charset are holding your credentials for the database connection.
|
|
If you need to specify a port to access the database, you can do so by appending ":portnumber" to the database.hostname variable.
|
|
|
|
'database' => [
|
|
'hostname' => 'your.mysqlhost.com:123456',
|
|
]
|
|
|
|
If all of the following environment variables are set, Friendica will use them instead of the previously configured variables for the db:
|
|
|
|
MYSQL_HOST
|
|
MYSQL_PORT
|
|
MYSQL_USERNAME
|
|
MYSQL_PASSWORD
|
|
MYSQL_DATABASE
|
|
|
|
## Config values that can only be set in config/local.config.php
|
|
|
|
There are some config values that haven't found their way into the administration page.
|
|
This has several reasons.
|
|
Maybe they are part of a current development that isn't considered stable and will be added later in the administration page when it is considered safe.
|
|
Or it triggers something that isn't expected to be of public interest.
|
|
Or it is for testing purposes only.
|
|
|
|
**Attention:** Please be warned that you shouldn't use one of these values without the knowledge what it could trigger.
|
|
Especially don't do that with undocumented values.
|
|
|
|
These configurations keys and their default value are listed in `static/defaults.config.php` and should be overwritten in `config/local.config.php`.
|
|
|
|
## Administrator Options
|
|
|
|
Enabling the admin panel for an account, and thus making the account holder admin of the node, is done by setting the variable
|
|
|
|
'config' => [
|
|
'admin_email' => 'someone@example.com',
|
|
]
|
|
|
|
|
|
Where you have to match the email address used for the account with the one you enter to the `config/local.config.php` file.
|
|
If more then one account should be able to access the admin panel, separate the email addresses with a comma.
|
|
|
|
'config' => [
|
|
'admin_email' => 'someone@example.com,someoneelse@example.com',
|
|
]
|
|
|
|
If you want to have a more personalized closing line for the notification emails you can set a variable for the `admin_name`.
|
|
|
|
'config' => [
|
|
'admin_name' => 'Marvin',
|
|
]
|
