when building tile server, can not download Shapefile

I have solved the problem that can not download the shapefile . As network is not good and the shapefile is too big, we can not download the shapefile zip . So we open the shell file 'openstreetmap-carto/external-data.yml', and get the info,as following,

settings:
  temp_schema: loading
  schema: public
  data_dir: data
  database: gis
  metadata_table: external_data
sources:
  simplified_water_polygons:
    # The type of file this source is
    type: shp
    # Where to get it
    url: https://osmdata.openstreetmap.de/download/simplified-water-polygons-split-3857.zip
    # The location within the archive
    file: simplified-water-polygons-split-3857/simplified_water_polygons.shp
    archive:
      format: zip
      # Files to extract from the archive
      files:

  water_polygons:
    type: shp
    url: https://osmdata.openstreetmap.de/download/water-polygons-split-3857.zip
    file: water-polygons-split-3857/water_polygons.shp
    archive:
      format: zip
      files:
        icesheet_polygons:
    type: shp
    url: https://osmdata.openstreetmap.de/download/antarctica-icesheet-polygons-3857.zip
    file: antarctica-icesheet-polygons-3857/icesheet_polygons.shp
    archive:
      format: zip
      files:
        icesheet_outlines:
    type: shp
    url: https://osmdata.openstreetmap.de/download/antarctica-icesheet-outlines-3857.zip
    file: antarctica-icesheet-outlines-3857/icesheet_outlines.shp
    ogropts:
      - "-explodecollections"
    archive:
      format: zip
      files:

  ne_110m_admin_0_boundary_lines_land:
    type: shp
    url: http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/ne_110m_admin_0_boundary_lines_land.zip
    file: ne_110m_admin_0_boundary_lines_land.shp
    ogropts: &ne_opts
      - "--config"
      - "SHAPE_ENCODING"
      - "WINDOWS-1252"
      - "-explodecollections"
      # needs reprojecting
      - '-t_srs'
      - 'EPSG:3857'
    archive:
      format: zip
      files:

Then we download all the 5 *zip files manually , and put them to your web server, for me , The url is http://127.0.0.1/osm/

  antarctica-icesheet-outlines-3857.zip 2020-07-24 09:37    51M  
  antarctica-icesheet-polygons-3857.zip 2020-07-24 09:37    51M  
  ne_110m_admin_0_boundary_lines_land.zip   2020-07-24 09:41    45K  
  simplified-water-polygons-split-3857.zip  2020-07-24 09:36    23M  
  water-polygons-split-3857.zip 2020-07-24 09:37    610M

At last, we modify the shell file 'openstreetmap-carto/external-data.yml' ，instead of the url download to ours. As following,

settings:
  temp_schema: loading
  schema: public
  data_dir: data
  database: gis
  metadata_table: external_data
sources:
  simplified_water_polygons:
    # The type of file this source is
    type: shp
    # Where to get it
    #url: https://osmdata.openstreetmap.de/download/simplified-water-polygons-split-3857.zip
    url: http://127.0.0.1/osm/simplified-water-polygons-split-3857.zip
    # The location within the archive
    file: simplified-water-polygons-split-3857/simplified_water_polygons.shp
    ...

It's OK.
