centos搭建redis 一主多從 哨兵
master：192.168.3.34 slave： 192.168.3.4
哨兵1：(sentinel1) ：192.168.3.34 哨兵2：(sentinel2) ：192.168.3.4
##環境安裝
-- 下載壓縮包 wget http://download.redis.io/releases/redis-4.0.6.tar.gz
-- 解壓縮 tar -zxvf redis-4.0.6.tar.gz -- 進入解壓後的redis目錄,編譯和安裝 make -- 安裝 make install PREFIX=/data/server/redis
-- 複製解壓縮的redis中的redis.conf和sentinel.conf 檔案到/data/server/redis/bin
##主從配置
master： --> vim redis.conf bind 0.0.0.0 protected-mode no daemonize yes slave-read-only yes slave-priority 100 appendonly yes appendfilename "appendonly_7001.aof" appendfsync everysec slave： --> vim redis.conf bind 0.0.0.0 protected-mode no daemonize yes slave-read-only yes slave-priority 90 appendonly yes slaveof 192.168.3.34 6379 appendfilename "appendonly_7001.aof" appendfsync everysec
##哨兵配置
master： --> vim sentinel.conf daemonize yes protected-mode no sentinel monitor redis1 192.168.3.34 6379 2
slave： --> vim sentinel.conf daemonize yes protected-mode no sentinel monitor redis1 192.168.3.34 6379 2
##啟動
--啟動redis ./redis-server redis.conf
--啟動哨兵 ./redis-server sentinel.conf
