Django使用redis存储Session实例

1、登录CentOS7系统，打开终端，启动redis-server服务器

2、再开一个终端，进入python虚拟环境，使用pip安装django-redis包，创建Django工程，创建工程的应用，命令如下：workon djandotestpip install django-redisdjango-admin startproject djrediscd djredispython manage.py startapp book

3、在工程的settings.py文件，添加应用，并添加redis配置信息cd djredisvi settin爿讥旌护gs.py修改部分的settings.py文件内容如下：INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'book.apps.BookConfig',]CACHES = { 'default':{ 'BACKEND':'django_redis.cache.RedisCache', 'LOCATION':'redis://127.0.0.1:6379/1', 'OPTIONS':{ 'CLIENT_CLASS':'django_redis.client.DefaultClient', } }}SESSION_ENGINE = 'django.contrib.sessions.backends.cache'SESSION_CACHE_ALIAS = 'default'
