redis-py Sentinel的使用

Sentinel初始化例子

from redis.sentinel import Sentinel
conf = {
    'sentinel': [('10.160.84.01', 26379), ('10.160.85.02', 26379), ('10.160.86.03', 26379)],
    'master_group_name': 'mymaster',
    #连接sentinel配置
    'sentinel_conf': { 
        'socket_timeout': 3,
        'socket_keepalive': True,
        'password': 'w2opw723DaAp0rUc'
    },
    'connection_conf': {
        'socket_timeout': 3,
        'retry_on_timeout': True,
        'socket_keepalive': True,
        'max_connections': 5,
        'db': 0,
        'password': 'w2opw723DaAp0rUc',
        'encoding': 'utf8'
    }
}
sentinel = Sentinel(conf['sentinel'],sentinel_kwargs=conf['sentinel_conf'],**conf['connection_conf'])
sentinel.discover_master(conf['master_group_name'])
cli = sentinel.master_for(conf['master_group_name'])
cli.set('hello', 'word')
cli.get('hello')
