安装

运行pip install django-redis-sessions-fork

或下载tarball并运行python setup.py install

将redis_sessions_fork.session设置为您的会话引擎，如下所示

SESSION_ENGINE = 'redis_sessions_fork.session'

配置

# all these options are defaults, you can skip anyone
SESSION_REDIS_HOST = '127.0.0.1'
SESSION_REDIS_PORT = 6379
SESSION_REDIS_DB = 0
SESSION_REDIS_PASSWORD = None
SESSION_REDIS_PREFIX = None

# if you prefer domain socket connection
# you can just add this line instead of SESSION_REDIS_HOST and SESSION_REDIS_PORT
SESSION_REDIS_UNIX_DOMAIN_SOCKET_PATH = '/var/run/redis/redis.sock'

# you can also use redis from url
SESSION_REDIS_URL = 'redis://127.0.0.1:6379/0'

# also available setup connection via redis.ConnectionPool like
SESSION_REDIS_CONNECTION_POOL = 'random.app.redis_connection_pool'

如果您是heroku.com的愉快用户

您可以完全跳过redis配置

django-redis-sessions-fork已经为redis云提供了预配置

序列化器

Django>=1.5.3 支持不同的会话序列化器，例如django.contrib.sessions.serializers.PickleSerializer和django.contrib.sessions.serializers.JSONSerializer

另外，您可以使用ujson序列化器，它比默认序列化器更快

pip install ujson

然后

SESSION_SERIALIZER = 'redis_sessions_fork.serializers.UjsonSerializer'

此外，还可以配置ujson编码，如下所示

SESSION_REDIS_JSON_ENCODING = 'utf8' # default is 'latin-1'
