ants-go

open source, restful, distributed crawler engine

I wrote a crawler engine named ants in python base on scrapy. But sometimes, dynamic language is chaos.
So I start to write it in a compile language.

I design the crawler framework by imitating scrapy.
such as downloader,scraper,and the way user write customize spider,
but in a compile way

I design my distributed architecture by imitating elasticsearch.
it spire me to do a engine for distributed crawler

go get github.com/PuerkitoBio/goquery
go get github.com/go-sql-driver/mysql

go get github.com/wcong/ants-go
go install github.com/wcong/ants-go

cd bin
./ants-go

curl 'http://localhost:8200/cluster'

curl 'http://localhost:8200/spiders'

curl 'http://localhost:8200/crawl?spider=spiderName'

to test cluster in one computer,you can run it from different port in different terminal

one node,use the default port tcp 8300 http 8200

cd bin
./ants-go

the other node set tcp port and http port

cd bin
./ants-go -tcp 9300 -http 9200

there are some flags you can set,check out the help message

./ants-go -h
./ants-go -help
