I try create SLD style in QGIS and export to GeoServer. And I have trouble with VendorOption name="placement">lastPoint<

Yes, I readed GeoServer import SLD style from QGIS issue on 'se:Stroke' this question and come at the end of the Symbolizer VendorOption but it isn't work.

sld look like:

    Just to clarify - is the issue that the entire dataset doesn't display? Or is the actual issue that you want the symbology to be exactly the same?

The whole point of VendorOption is to warn you that it is something a vendor has added to the standard and that it probably won't work if you move to a different vendor (i.e. from QGis to GeoServer).

If you want to add a symbol to the beginning and end of the line in GeoServer then you need to use a function to transform your line into a point (Start_Point and End_Point) along with the related functions to give you the correct angle as described in this answer.
