首先服務器搭建哨兵模式(我這裏使用的是Windows8系統),感謝兩位博主,少走很多彎路,在此給出連接:服務器哨兵模式搭建和整合哨兵模式java
什麼一些介紹就不介紹了,能夠看一下鏈接,比較詳細,初次接觸,當時很迷茫,特糾結整合時候服務器是否須要開啓哨兵模式,由於在整合的時候確認了master,結果很顯然是須要的node
先配置服務器(本地)哨兵模式,直接從redis官網下載安裝或者解壓版,安裝後的目錄結構linux
而後配置哨兵模式正則表達式
port:6379
#設置鏈接密碼
requirepass:grs
#鏈接密碼
masterauth:grs
slave.6380.conf配置redis
port:6380
dbfilename dump6380.rdb
#配置master
slaveof 127.0.0.1 6379
slave.6381.conf配置spring
port 6381 slaveof 127.0.0.1 6379 dbfilename "dump.rdb"
配置哨兵sentinel.63791.conf(其餘兩個哨兵配置文件一致,只修改端口號碼便可)apache
port 63791 #主master,2個sentinel選舉成功後纔有效,這裏的master-1是名稱,在整合的時候須要一致,這裏能夠隨便更改 sentinel monitor master-1 127.0.0.1 6379 2 #判斷主master的掛機時間(毫秒),超時未返回正確信息後標記爲sdown狀態 sentinel down-after-milliseconds master-1 5000 #若sentinel在該配置值內未能完成failover操做(即故障時master/slave自動切換),則認爲本次failover失敗。 sentinel failover-timeout master-1 18000 #選項指定了在執行故障轉移時, 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 sentinel config-epoch master-1 2
須要注意的地方windows
一、若經過redis-cli -h 127.0.0.1 -p 6379鏈接,無需改變配置文件,配置文件默認配置爲bind 127.0.0.1(只容許127.0.0.1鏈接訪問)若經過redis-cli -h 192.168.180.78 -p 6379鏈接,需改變配置文件,配置信息爲bind 127.0.0.1 192.168.180.78(只容許127.0.0.1和192.168.180.78訪問)或者將bind 127.0.0.1註釋掉(容許全部遠程訪問)緩存
二、masterauth爲所要鏈接的master服務器的requirepass,若是一個redis集羣中有一個master服務器,兩個slave服務器,當master服務器掛掉時,sentinel哨兵會隨機選擇一個slave服務器充當master服務器,鑑於這種機制,解決辦法是將全部的主從服務器的requirepass和masterauth都設置爲同樣。服務器
三、sentinel monitor master-1 127.0.0.1 6379 2 行尾最後的一個2表明什麼意思呢?咱們知道,網絡是不可靠的,有時候一個sentinel會由於網絡堵塞而誤覺得一個master redis已經死掉了,當sentinel集羣式,解決這個問題的方法就變得很簡單,只須要多個sentinel互相溝通來確認某個master是否真的死了,這個2表明,當集羣中有2個sentinel認爲master死了時,才能真正認爲該master已經不可用了。(sentinel集羣中各個sentinel也有互相通訊,經過gossip協議)。
依次啓動redis
redis-server master.6379.conf
redis-server slave.6380.conf
redis-server slave.6381.conf
redis-server sentinel.63791.conf --sentinel(linux:redis-sentinel sentinel.63791.conf)其餘兩個哨兵也這樣啓動
使用客戶端查看一下master狀態
查看一下哨兵狀態
如今就能夠在master插入數據,全部的redis服務均可以獲取到,slave只能讀
