export NGX_PREFIX=/path/to/install

./configure --prefix=$NGX_PREFIX \
  --add-module=../nginx-upload-module  \
  --with-debug \
  --with-http_stub_status_module \
  --with-http_flv_module \
  --with-http_ssl_module \
  --with-http_dav_module \
  --with-http_gzip_static_module \
  --with-http_realip_module \
