django中python中对redis进行读写分离封装

django中创建cache.py,写如下代码

from redis import Redis

from django.conf import settings

class MSRedis(object):
    '''读写分离客户端（只针对程序中用到的命令）'''
    def __init__(self,conf):
        self.master = Redis(**conf['Master'])
        self.slave = Redis(**conf['Slave'])
        self.read_commands = [
            'ttl', 'exist', 'expire', 'get', 'keys',
            'hget', 'hgetall', 'hkeys', 'hmget',
            'sismember', 'smembers', 'sdiff', 'sinter', 'sunion'
            'zrevrange', 'zrevrangebyscore', 'zrevrank', 'zscore'
        ]

    def __getattribute__(self, name):
        if name in ['master','slave', 'read_commands']:
            return  object.__getattribute__(self,name)
        elif name in self.read_commands:
            return self.slave.__getattribute__(name)
        else:
            return self.master.__getattribute__(name)

rds = MSRedis(settings.REDIS)


settings.py文件中添加配置：

REDIS = {

    'Master':{
        'host':'127.0.0.1',
        'port': '6379',
        'db': 1
    },
    'Slave':{
        'host':'127.0.0.2',
        'port': '6379',
        'db': 1
    },
}

然后django项目中用到redis的地方调用rds即可。
