挂机了 ，设置请求超时时间，请求间隔，重试次数，检查ua、代理
UA是有的，从一开始就是0了，请求超时时间请求间隔应该没问题，或许我应该试试代理
代理应该也没事，因为我用其他的爬虫程序能够爬
降速试试吧
RETRY_ENABLED = True # 重新请求
RETRY_TIMES = 3 # 请求次数
DOWNLOAD_DELAY = 2 # 下载延时
CONCURRENT_REQUESTS = 3
DOWNLOAD_TIMEOUT = 120 ## 超时限制
抱歉，这个方法尝试了，结果还是无效，或者请问我在网上查到了一个解决方法，你能够看看是什么意思是否有用嘛
问题：分布式爬虫一直都是显示Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min)。
解决：你使用的肯定是window的redis数据库，而且lpush时，使用的是redis。windos那个文件，这样插入的redis_key，在你爬虫服务器上是查不到这个值的。
使用 redis-cli -h redis的ip -p 6379 这样链接数据，再lpush值进去才行。

应该跟这个没关系，不过不妨一试，先不用redis，换成正常的scrapy爬取机制试试看
