Redis.config

LUA SCRIPTING

• lua-time-limit

执行lua script允许执行时间上限，超过则会被删除．(毫秒)

# 预设
lua-time-limit 5000

REDIS CLUSTER

• cluster-enabled

是否启用Redis Server Cluster模式．

# 预设
# cluster-enabled yes

• cluster-config-file

Redis Server Cluster 设定档案名称．

# 预设
# cluster-config-file nodes-6379.conf

• cluster-node-timeout

设定Redis Server Cluster 节点连接逾时．(毫秒)

# 预设
# cluster-node-timeout 15000

• cluster-replica-validity-factor

如果设爲0，则一个Replica将总是尝试故障转移一个Master。如果设爲>0，则最大失去连接的时间是node timeout乘以这个factor。

# 预设
# cluster-replica-validity-factor 10

• cluster-migration-barrier

设定Master和Replica保持连接的最小数量（最少与多少个Replica保持连接），也就是说至少与其它多少Replica保持连接的Replica才有资格成爲Master。

# 预设
# cluster-migration-barrier 1

• cluster-allow-replica-migration

设定是否允许自动切换Replica成为Ｍaster．

# 预设
# cluster-allow-replica-migration yes

• cluster-require-full-coverage

设定yes时，key space没有达到百分之多少时停止接受写请求。如果设置爲no，将仍然接受查询请求，即使它只是请求部分key．

# 预设
# cluster-require-full-coverage yes

• cluster-replica-no-failover

设定为yes时，可防止从设备尝试对其进行故障转移Master在主故障期间，除非强制执行手动故障转移。

# 预设
# cluster-replica-no-failover no

• cluster-allow-reads-when-down

是否允许在Cluster机制停止时还可以读取．

# 预设
# cluster-allow-reads-when-down no

CLUSTER DOCKER/NAT support

• cluster-announce-ip

设定docker Cluster IP

• cluster-announce-tls-port

设定docker Cluster TLS Port

• cluster-announce-port

设定docker Cluster 对外 Port

• cluster-announce-bus-port

slowlog-log-slower-than 10000

• slowlog-max-len

设定记录操作慢的日志最多保存长度．

# 预设
slowlog-max-len 128

LATENCY MONITOR

• latency-monitor-threshold

设定一个延时阈值来开啓延时监控，藉此收集资料确认Redis操作延迟问题。(毫秒)
