# Configuration Files Each service has its own configuration file `/etc/squirro/.ini`. Additionally, there is a common configuration file that applies to all services at `/etc/squirro/common.ini`. For individual `.ini` files, see the following links: - [common.ini](config-ini.md#admin-config-ini), located at `/etc/squirro/common.ini`, configures common settings for all of the Squirro services. - [configuration.ini](config-ini.md#admin-config-ini), located at `/etc/squirro/configuration.ini`, configures the workings of the configuration service. - [convert.ini](convert-ini.md#admin-convert-ini), located at `/etc/squirro/convert.ini`, configures the content version. - [datasource.ini](datasource-ini.md#admin-datasource-ini), located at `/etc/squirro/datasource.ini`, configures the workings of the Datasource Service. - [digestmailer.ini](digestmailer-ini.md#admin-digestmailer-ini), located at `/etc/squirro/digestmailer.ini`, configures email template rendering. - [emailsender.ini](emailsender-ini.md#admin-emailsender-ini), located at `/etc/squirro/emailsender.ini`, configures email sending from the Squirro system. - [filtering.ini](filtering-ini.md#admin-filtering-ini), located at `/etc/squirro/filtering.ini`, configures the filtering process, which is responsible for search tagging and alerts. - [frontend.ini](frontend-ini.md#admin-frontend-ini), located at `/etc/squirro/frontend.ini`, configures the workings of the Squirro frontend user interface. - [ingester.ini](ingester-ini.md#admin-ingester-ini), located at `/etc/squirro/ingester.ini`, configures the workings of the Ingester Service. - [storage.ini](storage-ini.md#admin-storage-ini), located at `/etc/squirro/storage.ini`, configures the file storage buckets that hold uploaded and generated files. - [topic.ini](topic-ini.md#admin-topic-ini), located at `/etc/squirro/topic.ini`, configures the workings of the topic API, one of the core services of the Squirro platform. - [user.ini](user-ini.md#admin-user-ini), located at `/etc/squirro/user.ini`, configures the user authentication service, including OAuth2 client registration. Finally, in addition to the `.ini` files above, Squirro supports configuration files in the [/etc/sysconfig](sysconfig-dir.md#admin-sysconfig-dir) directory, a convention commonly used in Red Hat Enterprise Linux.
