django使用redis做缓存

Django是一个高级的Python Web框架，它鼓励快速开发和干净、实用的设计，在Django中，我们可以使用Redis作为缓存后端，以提高Web应用的性能，本文将介绍如何在Django中使用Redis配置缓存的方法。

安装Redis和Djangoredis

1、安装Redis

我们需要在服务器上安装Redis，在Ubuntu系统中，可以使用以下命令安装：

sudo aptget update
sudo aptget install redisserver

2、安装Djangoredis

接下来，我们需要安装Djangoredis库，可以使用以下命令安装：

pip install djangoredis

配置Django项目

1、在项目的settings.py文件中，添加以下内容：

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

这里，我们指定了使用django_redis库作为缓存后端，并连接到本地的Redis服务器。LOCATION参数是Redis服务器的地址和端口，OPTIONS参数是可选的配置选项。

2、在项目的urls.py文件中，添加以下内容：

from django.urls import include, path
from django_redis import cache as redis_cache
from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
