#Sentinel（哨兵）進程去監視一個名爲 mymaster 的主服務器，這個主服務器的 IP 地址爲 172.16.0.23 ， 端口號爲 6379，而將這個主服務器判斷爲失效至少須要 1 個 Sentinel（哨兵）進程的贊成
#注意：
#1.若是2個哨兵，有1個哨兵掛了，那麼主從是不會切換的，狀態都會在odwon(客觀下線狀態)，因此要哨兵高可用，至少要3個哨兵
#2.若是隻有1個哨兵 最後面的1是無所謂的。狀態會是sdown(主觀下線狀態)。

#在執行故障轉移時，最多能夠有多少個從服務器同時對新的主服務器進行同步，這個數字越小，完成故障轉移所需的時間就越長。(通常設置爲1)

#實現主從切換，完成故障轉移的所須要的最大時間值。若Sentinel（哨兵）進程在該配置值內未能完成故障轉移的操做（即故障時master/slave自動切換），則認爲本次故障轉移操做失敗
