python连接redis sentinel集群
安装redis客户端
pip install redis
代码示例
import redis from redis.sentinel import Sentinel # 连接哨兵服务器(主机名也可以用域名) sentinel = Sentinel([('172.31.0.2', 5001), ('172.31.0.3', 5001), ('172.31.0.4', 5001), ('172.31.0.5', 5001) ], socket_timeout=0.5) mymaster 是运维人员配置哨兵模式的数据库名称,实际名称按照个人部署案例来填写 # 获取主服务器地址 master = sentinel.discover_master('mymaster') print(master) # 输出:('172.31.0.2', 5001) # 获取从服务器地址 slave = sentinel.discover_slaves('mymaster') print(slave) # 输出:[('172.31.3', 5001), ('172.31.0.4', 5001), ('172.31.0.5', 5001)] # 获取主服务器进行写入 master = sentinel.master_for('mymaster', socket_timeout=0.5, password='redis_auth_pass', db=15) w_ret = master.set('foo', 'bar') # 输出:True # # 获取从服务器进行读取(默认是round-roubin) slave = sentinel.slave_for('mymaster', socket_timeout=0.5, password='redis_auth_pass', db=15) r_ret = slave.get('foo') print(r_ret) # # 输出:bar
