redis介绍

# 介绍 c s 架构的软件
	redis：非关系型数据库【存数据的地方】nosql数据库，内存存储，速度非常快，可以持久化【数据从内存同步到硬盘】，数据类型丰富【5大数据类型：字符串，列表，哈希(字典),集合，有序集合】，key-value形式存储【根本没有表的结构，相当于咱们的字典】
    
    -nosql：指非关系型数据库：1 不限于SQL  2 没有sql
    
# redis 为什么这么快
	-1 高性能的网络模型：IO多路复用的epoll模型，承载住非常高的并发量
    -2 纯内存操作，避免了很多io
    -3 单线程架构，避免了线程间切换的消耗
    	-6.x之前：单线程，单进程
    	-6.x以后，多线程架构，数据操作还是使用单线程，别的线程做数据持久化，其他操作

# redis 应用场景（了解）
	1 当缓存数据库使用，接口缓存，提高接口响应速度
    	-请求进到视图---》去数据查询[多表查询，去硬盘取数据：速度慢]----》转成json格式字符串---》返回给前端
        -请求进到视图---》去redis[内存]----》取json格式字符串---》返回给前端
    2 做计数器：单线程，不存在并发安全问题
    	-统计网站访问量
        -个人站点浏览量
        -文章阅读量
        
    3 去重操作：集合
    4 排行榜：有序集合
    	-阅读排行榜
        -游戏金币排行榜
        
    5 布隆过滤器
    6 抽奖
    7 消息队列

redis安装

# 开源软件：使用c语言写的---【编译型语言，在操作系统运行，要编译成可执行文件，由于采用了IO多路复用的epoll模型，所以它不支持windows，只有linux操作系统支持epoll】

# 微软官方：改了，编译成可执行的安装包，下载一路下一步安装
	-版本没有最新

    
    
# 官网：https://redis.io/
	-下载完是源代码：c语言源码 ：https://redis.io/download/#redis-stack-downloads
    -最稳定：6.x
    -最新7.x

# 中文网：http://redis.cn/download.html
	-上面最新只到5.x
    
    
# win版本下载地址
    # 最新5.x版本 https://github.com/tporadowski/redis/releases/
    # 最新3.x版本 https://github.com/microsoftarchive/redis/releases
	下载完一路下一步即可，具体可参照：https://www.cnblogs.com/liuqingzheng/p/9831331.html
    
    
# win装完会有redis服务
	-启动服务，手动停止
    -客户端链接：redis-cli -h 127.0.0.1 -p 6379
    -简单命令：
    	set name lqz
        get name
        ping
        
    -停掉服务：
    	-去win服务点关闭
        -客户端关闭：shutdown
    

#mysql 服务端
#mysql客户端
	-navicate
    -命令窗口cmd
    -python操作
    
    
# redis 服务器端
# redis 客户端
	-redis-cli
    -图形化工具：redis-destop-management
    -python操作

python操作redis

# pip3 install redis

from redis import Redis

conn=Redis( host="localhost",port=6379)
# conn.set('name','xxx')
print(conn.get('name'))
conn.close()

redis连接池

POOL.py

import redis

pool = redis.ConnectionPool(max_connections=200, host='127.0.0.1', port=6379)

redis_pool_demo.py

from redis import Redis
from threading import Thread

# 直接链接
# def get_name_from_redis():
#     conn = Redis(host="localhost", port=6379)
#     print(conn.get('name'))
#     conn.close()
#
#
# for i in range(100):
#     t=Thread(target=get_name_from_redis)
#     t.start()
#
#
# import time
# time.sleep(10)


### 使用连接池链接
import redis
from POOL import pool
def get_name_from_redis():
    # 创建一个连接池，保证它是单例，全局只有一个pool对象：使用模块导入方式实现单例

    conn = redis.Redis(connection_pool=pool) #m每执行一次会从池中取一个链接，如果没有，等待
    res=conn.get('name')
    print(res)
    conn.close()


for i in range(100):
    t=Thread(target=get_name_from_redis)
    t.start()


import time
time.sleep(10)
