This is an example configuration on how to run two different map styles (OSMBright and openstreetmap-carto) on one renderd and leaflet server. For an instruction on how to install a tileserver with openstreetmap-carto and leaflet, see here, for instructions for OSMBright, click here.
renderd.conf
Each style has an own section with an own tiledir and URI. Make sure that both tiledirs exists and is owned by the user which runs renderd.

The tiles in http://localhost/osm_tiles are now rendered with OSMBright and http://localhost/osm_tiles-carto with openstreetmap.carto.
