Make sure you have given the below format in th/etc/mongod.conf for security option as you have made an mistake in security option.security:  authorization: 'enabled'  ----->  to enable authentication    authentication: 'disabled'  -------> to disable the authentication
if you dont want to secure your MongoDb database,just comment this security directive in /etc/mongod.conf
Note:

Ensure there exists an white space between the authorization and 'enabled',only then the service of mongoDB will run successfully.
