nominatim setup with local tiles

Hi, From Google, I understand that to create an interface same as https://www.openstreetmap.org, where User can search for location, I will need to use nominatim. I am reading bellow link, http://nominatim.org/release-docs/latest/appendix/Install-on-Ubuntu-16/

I understand i will need to install a new server, but what I dont understand is, how will create relation between my existing tiles server 192.168.1.32/hot and this new nominatim server ? how nomatiam will know from where to find tiles infomration ( /var/lib/mod_tile/ajt/ in 192.168.1.32 )

also,

Here, i am just working with one country. I guess i can build nominatim in the same server where i have the files, but still i have the same qustion , how will nominatim know from where to get teh tiles information ? is this from this section , what Path its looking for ? the tiles path ?

@define('CONST_Osm2pgsql_Flatnode_File', '/path/to/flatnode.file');

My tiles configurtion:

Localserver for tiles : 192.168.1.32
web access : 192.168.1.32/hot
file system location : /var/lib/mod_tile/ajt/

Thanks for the help.
