将分布式-队列的实现交给redis

 

import requests
import re
import time
from redis import Redis
import threading


REDIS_HOST, REDIS_PORT, PASSWORD = '192.168.2.51', '6379', 'mypwd'
rds = Redis(host=REDIS_HOST, port=REDIS_PORT, password=PASSWORD)


f, url_l, filter_replace_l = 'kwaddress_address_20180227.json', [], ['\n', '\t', ' ']
with open(f,'r',encoding='utf-8') as fr:
for i in fr:
try:
ii =i.split('address":"')[-1].split('"}')[0]
#url_l.append(ii)
rds.sadd('chk_url_all', ii)
except Exception as e:
print(e)


去内存,持久化
import pymysql
from redis import Redis
import time

h, pt, u, p, db = '192.168.2.210', 3306, 'root', 'nfwt&2016', 'xl_product_DONOT_REMOVE'

except Exception as e:
print(e)
return ()

cursor.execute(sql)
conn.commit()
cursor.close()

多线程

发布代码至多台机器





redis 自典型 支持更新
rds = return_redis(redis_key)
rds.hset(my_dict_name, uid, uid_info)
