You really need to sit down with the introductory documentation. ArcSDE does not publish
services, it's just a mechanism for ArcGIS clients to access spatial data and other ancillary
tables in a database. 
 
The location of the ArcSDE install is more influenced by the volume of application server 
clients (and whether you can afford to license an additional server).  If you are not yet 
experienced with ArcGIS components, it's unlikely you will need any of the more exotic 
deployment configurations to start.

thank you for the quick response.

But i want use Arc SDE geo database and publish some services to the arcgis server.

If i want use arcsde geodatabase what are the steps we need to follow.i think

1) we have to install arcsde server seperately : is it correct or not?( which was already installed arcgis server machine)
2) if it is not install arcsde seperately what are the steps we need to follow to maintain the arcsde geodata base

can help this questions.
