基于docker搭建redis-sentinel集群的方法示例

#端口号
port 26379
dir /tmp
# mymaster：自定义集群名，2:投票数量必须2个sentinel才能判断主节点是否失败
sentinel monitor mymaster <ip> <port> 2
# 指的是超过5000秒，且没有回复，则判定主节点不可达
sentinel down-after-milliseconds mymaster 5000
# 表示在故障转移的时候最多有numslaves在同步更新新的master
sentinel parallel-syncs mymaster 1
# 故障转移超时时间
sentinel failover-timeout mymaster 5000

#端口号
port 26380
dir /tmp
# mymaster：自定义集群名，2:投票数量必须2个sentinel才能判断主节点是否失败
sentinel monitor mymaster <ip> <port> 2
# 指的是超过5000秒，且没有回复，则判定主节点不可达
sentinel down-after-milliseconds mymaster 5000
# 表示在故障转移的时候最多有numslaves在同步更新新的master
sentinel parallel-syncs mymaster 1
# 故障转移超时时间
sentinel failover-timeout mymaster 5000

#端口号
port 26381
dir /tmp
