本文深入探讨了在集群环境中使用Nutcracker和Redis的技术细节，包括Nutcracker的编译、配置以及Redis的服务器设置、哨兵模式、Sentinel监控等关键步骤。同时介绍了如何在Redis中实现数据复制、故障转移和高可用性。

bdrq:

在集群中,如果master挂掉,那么slave将被提升为master, master再次启动是,会变成slave

nutcracker

1.编译nutcracker

$ CFLAGS="-ggdb3 -O0" ./configure --enable-debug=full
$ make
$ sudo make install

2.Config nutcracker

alpha:
  listen: 0.0.0.0:22120
  hash: fnv1a_64
  distribution: ketama
  auto_eject_hosts: true
  server_retry_timeout: 2000
  server_failure_limit: 1
  redis: true
  servers:
   - server1
     127.0.0.1:6370:1
     127.0.0.1:6380:1
   - server2
     127.0.0.1:6371:1
     127.0.0.1:6381:1
   - server3
     127.0.0.1:6372:1
     127.0.0.1:6382:1
