Oracle is not starting

I have a centos 7 server and it has Oracle installed.

I have a configuration script to initialize the databases and when I finish uploading the script and listener , I get this error:

  

ORA-12514: TNS: listener does not currently know of service requested in connect descriptor

I opened the file listener.ora and got like this:

LISTENER =
 (DESCRIPTION_LIST =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = IPC)(KEY = CHAVE))
     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.11)(PORT = 1521))
   )
 )

Is not the instance services missing from this file? or is it automatic?
