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

sentinel启动后需要手动将配置文件对应的调整为sentinel deny-scripts-reconfig no,否则不支持命令行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
查看所有监控master及其配置信息

sentinel master monitor_name
查看指定监控master及其配置信息

sentinel failover monitor_name
手动进行swithover切换主从，如果有多个slave会选择哪个slave做为新的master，待测试？

sentinel moniotr <name> <ip> <port> <quorum>
添加监视的master

sentinel remove monitor_name
将监视的为name的master移除监视

sentinel set <mastername> [<option> <value>]
修改监视的master的一些属性
down-after-milliseconds 过了这个时间考虑master go down
failover-timeout 刷新故障转移状态的最大时间
parallel-syncs slave同时reconfigure的个数
notification-script 设置通知脚本
client-reconfig-script 设置通知脚本
auth-pass 执行auth的密码
quorum 修改master的quorum

sentinel flushconfig

将sentinel信息写入到配置文件中
