django+redis [by Jsongo]

需要django-redis插件：https://django-redis.readthedocs.org/
不过安装它之前得先安装redis-py：https://github.com/andymccurdy/redis-py/
git clone下来后，运行python setup.py install 就ok了

装完redis-py后，要验证是否成功，可以运行一下下面几个命令：

>>> import redis 
>>> r = redis.StrictRedis(host='localhost', port=6379, db=0) 
>>> r.set('foo', 'bar') 
True 
>>> r.get('foo') 
'bar'

接下去安装django-redis：https://github.com/niwibe/django-redis
python setup.py install
装完之后，修改一下设置：vi /usr/local/lib/python2.7/dist-packages/django/conf/global_settings.py

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

如果是多个机器或多个端口，则用下面的配置：

CACHES = { 
    "default": { 
        "BACKEND": "redis_cache.cache.RedisCache", 
        "LOCATION": [ 
            "127.0.0.1:6379:1", 
            "127.0.0.1:6379:2", 
        ], 
        "OPTIONS": { 
            "CLIENT_CLASS": "redis_cache.client.ShardClient", 
        } 
    } 
}

考虑到容灾的话，用下面配置（第一个失效了，自动切换到之后几个）：

CACHES = { 
    "default": { 
        "BACKEND": "redis_cache.cache.RedisCache", 
        "LOCATION": "127.0.0.1:6379:1/127.0.0.2:6379:1", 
        "OPTIONS": { 
            "CLIENT_CLASS": "redis_cache.client.SimpleFailoverClient", 
        } 
    } 
}
