爬虫项目并发版演示

• 启动相亲网站 mockserver

go run mockserver/main.go

• 启动爬虫

go run crawler/main.go

爬虫项目分布式版演示

• 启动相亲网站 mockserver

go run mockserver/main.go

• 下载ES并本地启动

bin/elasticsearch

• 启动存储服务(数据存储到ES)

cd crawler_distributed/persist/server
go run itemsaver.go --port=9090

• 启动多个worker服务(爬取数据)

cd crawler_distributed/worker/server
go run worker.go --port=9091
go run worker.go --port=9092

• 启动爬虫

cd crawler_distributed
go run main.go --itemsaver_host=:9090 --worker_hosts=:9091,:9092

并行处理管道演示

示例：对大量数据的外部排序进行并行处理

• 生成大量数据(写到文件)

go run pipeline/createfile/main.go

• 演示单机版并行处理

go run pipeline/demo/main.go

• 演示网络版并行处理

go run pipeline/netdemo/main.go
