Step 1：Redis的下載安裝
官網下載redis 解壓並安裝：
[root@mycomputer ~]# cd /home/ [root@mycomputer home]# wget http://download.redis.io/releases/redis-4.0.11.tar.gz [root@mycomputer home]# tar -zxvf -C redis-4.0.11.tar.gz [root@mycomputer home]# cd redis-4.0.11/src [root@mycomputer src]# make 編譯中.... .... CC setproctitle.o CC hyperloglog.o CC latency.o CC sparkline.o LINK redis-server INSTALL redis-sentinel CC redis-cli.o LINK redis-cli CC redis-benchmark.o LINK redis-benchmark CC redis-check-dump.o LINK redis-check-dump CC redis-check-aof.o LINK redis-check-aof Hint: It’s a good idea to run ‘make test’ ;) [root@mycomputer src]# make install 安裝中... ... 完成安裝完成，可以看到此時，src文件夾下出現了一些綠色的文件，這些文件就是我們以後需要用到的命令文件
Step 2：Redis 主從複製的配置
1.在 redis 目錄下創建 config 和 data 文件夾：config 用來存放 redis.conf/sentinel.conf 配置文件, data 用來存放 .log 文件和 .rdb 文件
[root@mycomputer redis-4.0.11]# mkdir config [root@mycomputer redis-4.0.11]# mkdir data [root@mycomputer redis-4.0.11]# cd config/2.配置 redis master 端口 7000 : 創建 redis_7000.conf

[root@mycomputer redis-4.0.11]# cd src [root@mycomputer src]# ./redis-server /home/redis-4.0.11/config/redis_7000.conf [root@mycomputer src]# ./redis-server /home/redis-4.0.11/config/redis_7001.conf [root@mycomputer src]# ./redis-server /home/redis-4.0.11/config/redis_7002.conf這樣就啓動好了 redis 主從服務
Step 3：Sentinel 高可用配置
在 config 目錄下創建多個 sentinel.conf 文件 ：sentinel_26379.conf/sentinel_26380.conf/sentinel_26381.conf ....(端口號不同就行)
port 26379 daemonize yes dir "/home/redis-4.0.11/data" logfile "sentinel_26379.log" sentinel myid ac633fe2e30979a6e63e5bc26199ab2ace08f242 sentinel monitor mymaster redis服務ip 7000 2 sentinel auth-pass mymaster 123456 sentinel config-epoch mymaster 1 protected-mode no[root@mycomputer redis-4.0.11]# cd src [root@mycomputer src]# ./redis-sentinel /home/redis-4.0.11/config/sentinel_26379.conf [root@mycomputer src]# ./redis-sentinel /home/redis-4.0.11/config/sentinel_26380.conf [root@mycomputer src]# ./redis-sentinel /home/redis-4.0.11/config/sentinel_26381.conf完成此操作即實現了 Redis sentinel 高可用
ps：
1. master /slave 的 redis.conf 最好配置密碼（一定要配置密碼：否則 JedisSentinelPool 報錯）
2. master /slave 的 redis.conf 最好配置的密碼相同
3. master /slave 的 redis.conf 配置 protected-mode no（sentinel.conf 裏面同樣需要配置）
