See documentation here:

http://nginx.org/r/fastcgi_temp_path
http://nginx.org/r/scgi_temp_path
http://nginx.org/r/uwsgi_temp_path

Compiled-in defaults can be set during compilation using 
appopriate configure options:

  --http-fastcgi-temp-path=PATH      set path to store
                                     http fastcgi temporary files
  --http-uwsgi-temp-path=PATH        set path to store
                                     http uwsgi temporary files
  --http-scgi-temp-path=PATH         set path to store
                                     http scgi temporary files

FastCGI, SCGI, and uWSGI modules are compiled in by default, 
unless you explicitly disable them with appropriate configure 
options:

  --without-http_fastcgi_module      disable ngx_http_fastcgi_module
  --without-http_uwsgi_module        disable ngx_http_uwsgi_module
  --without-http_scgi_module         disable ngx_http_scgi_module

And once modules are compiled in, appropriate temp 
directories are created on start.
