Struggling

I have a mac and I am trying to create the wordpress blog
I have two website http://www.theseptictankshop.co.uk and http://www.theseptictankcompany.co.uk
I host both these sites on an apache server.
The instructions say to install this coding into the database
database name: wordpress
database host/server: localhost
database user: root
database password: root.
1) will this effect my data base login with opencart
2) will it affect my blogger with google?
Thanks
