I followed these two blogs to install server
1. http://koo.fi/blog/2015/03/19/openstreetmap-nominatim-server-for-geocoding/#Compile_Nominatim 
This explains ( and is the main blog which I followed) various steps
2. https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04
This explains how to setup swap files and install tiles if needed.

I will use Ubuntu 14.04 LTS as the platform. Just a basic install with ssh server. We will install Apache to serve http requests. Make sure you have enough disk space and RAM to hold the data and serve it efficiently. I used the Finland extract, which was about a 200 MB download. The resulting database was 26 GB after importing, indexing and adding Wikipedia data. The Wikipedia data probably actually took more disk space than the OSM data. My server has 4 GB RAM, which seems to be enough for this small data set.
