1、插入测试数据

--测试插入数据
[root@test01 ~]# vim /home/redis_insert_date.py
#!/usr/local/bin/python3
# coding=utf-8
import redis
import sys
import datetime

def create_testdata():
	r = redis.StrictRedis(host='172.31.0.xx', port=6379, password='xxx', db=0)
	counter = 0
	with r.pipeline(transaction=False) as p:
		for i in range(0, 1000):
			p.set('key:' + str(i), "value" + str(i))
			counter = counter + 1
			if (counter == 100):
				p.execute()
				counter = 0
				print("set by pipline loop")

if __name__ == "__main__":
	create_testdata()
[root@test01 ~]#
[root@test01 ~]# chmod +x /home/redis_insert_date.py
[root@test01 ~]# /home/redis_insert_date.py

2、使用scan命令批量删除指定前缀的数据 

--删除指定前缀的key 并且每次删除10个，但是不能控制删除的行数，直到删除掉所有满足条件的所有key
[root@LG-wiki-96 ~]# redis-cli -h 172.31.0.xx -p 6379 -a xxx -n 1 --scan --pattern "key:*" | xargs -L 10 redis-cli -h 172.31.0.xx -p 6379 -a xxx -n 0 del
