Nutch 不会抓取多个站点 [英] Nutch does not crawl multiple sites

问题描述

我正在尝试使用 Nutch 抓取多个网站.我的 seed.txt 看起来像这样:

I'm trying to crawl multiple sites using Nutch. My seed.txt looks like this:

http://1.a.b/
http://2.a.b/

我的 regex-urlfilter.txt 看起来像这样:

and my regex-urlfilter.txt looks like this:

# skip file: ftp: and mailto: urls
-^(file|ftp|mailto):

# skip image and other suffixes we can't yet parse
# for a more extensive coverage use the urlfilter-suffix plugin
-\.(gif|GIF|jpg|JPG|png|PNG|ico|ICO|css|CSS|sit|SIT|eps|EPS|wmf|WMF|zip|ZIP|ppt|PPT|mpg|MPG|xls|XLS|gz|GZ|rpm|RPM|tgz|TGZ|mov|MOV|exe|EXE|jpeg|JPEG|bmp|BMP|js|JS)$

# skip URLs containing certain characters as probable queries, etc.
-[?*!@=]

# skip URLs with slash-delimited segment that repeats 3+ times, to break loops
-.*(/[^/]+)/[^/]+\1/[^/]+\1/

# accept anything else
#+.
+^http://1.a.b/*
+^http://2.a.b/*

我在最后一部分尝试了以下内容:

I tried the following for the last part:

+^http://([a-z0-9]*\.)*a.b/*

唯一被抓取的网站是第一个.所有其他配置都是默认的.

The only site crawled is the first one. All other configuration is default.

我运行以下命令:

bin/nutch crawl urls -solr http://localhost:8984/solr/ -dir crawl -depth 10 -topN 10

有什么想法吗?！

谢谢！

推荐答案

在 regex-urlfilter.txt 中试试这个:

Try this in regex-urlfilter.txt :

旧设置:

# accept anything else
#+.
+^http://1.a.b/*
+^http://2.a.b/*

新插入:

# accept anything else
+.
