如果哨兵集群中的多数Sentinel进程认为Master存在SDOWN,共同利用 is-master-down-by-addr 命令互相通知后,则认为客观宕机Objectively Down, 简称 ODOWN 接下来利用投票算法,从所有slave节点中,选一台合适的slave将之提升为新Master节点,然后自动修改其它slave相关配置,指向新的master节点,最终实现故障转移failover Redis Se...
# When master_reboot_down_after_period is set to 0, Sentinel does not fail over # when receiving a -LOADING response from a master. This was the only supported # behavior before version 7.0. # # Otherwise, Sentinel will use this value as the time (in ms) it is willing to # ...

i.判断runnid,更新该master的runnid如果现在ri->runnid = NULL,如果非NULL,会比较两次runnid是否一致,如果不一致认为master重启过了,将发送消息到+reboot频道通知该master重启了 ii. down_after_period小于1000ms,则在down_after_period时间内发送一个ping命令,否则以1000ms为周期发送 ...

3)直接使用命令:slaveof {masterHost} { masterPort}生效。 综上所述,slaveof命令在使用时,可以运行期动态配置,也可以提前写到配置文件中。 比如:我在机器上启动2台Redis, 分别是6379 和6380 两个端口。 slaveof本身是异步命令,执行slaveof命令时,节点只保存主节点信息后返回,后续复制流程在节点内部异步执行,具...
Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps. - redis/sentinel.conf at 8.0-m02 · redis/redis
