sentinel monitor advertise 192.168.0.5 28001 2
sentinel set advertise client-reconfig-script /etc/redis/reconfig.sh
sentinel flushconfig

sentinel啟動后需要手動將配置文件對應的調整為sentinel deny-scripts-reconfig no,否則不支持命令行runtime修改client-reconfig-script
# SECURITY
#
# By default SENTINEL SET will not be able to change the notification-script
# and client-reconfig-script at runtime. This avoids a trivial security issue
# where clients can set the script to anything and trigger a failover in order
# to get the program executed.

#sentinel deny-scripts-reconfig yes

role命令
查看sentinel monitor的master names名字

sentinel masters
查看所有監控master及其配置信息

sentinel master monitor_name
查看指定監控master及其配置信息

sentinel failover monitor_name
手動進行swithover切換主從，如果有多個slave會選擇哪個slave做為新的master，待測試？

sentinel moniotr <name> <ip> <port> <quorum>
添加監視的master

sentinel remove monitor_name
將監視的為name的master移除監視

sentinel set <mastername> [<option> <value>]
修改監視的master的一些屬性
down-after-milliseconds 過了這個時間考慮master go down
failover-timeout 刷新故障轉移狀態的最大時間
parallel-syncs slave同時reconfigure的個數
notification-script 設置通知腳本
client-reconfig-script 設置通知腳本
auth-pass 執行auth的密碼
quorum 修改master的quorum

sentinel flushconfig

將sentinel信息寫入到配置文件中
