Step 1：Redis的下載安裝

官網下載redis 解壓並安裝：

[[email protected] ~]# cd /home/

[[email protected] home]# wget http://download.redis.io/releases/redis-4.0.11.tar.gz

[[email protected] home]# tar -zxvf -C redis-4.0.11.tar.gz

[[email protected] home]# cd redis-4.0.11/src

[[email protected] src]# make

編譯中.... ....

redis-check-aof Hint: It’s a good idea to run ‘make test’ ;)  

[[email protected] src]# make install

安裝中...... 完成

安裝完成，可以看到此時，src資料夾下出現了一些綠色的檔案，這些檔案就是我們以後需要用到的命令檔案

Step 2：Redis 主從複製的配置

1.在 redis 目錄下建立 config 和 data 資料夾：config 用來存放 redis.conf/sentinel.conf 配置檔案, data 用來存放 .log 檔案和 .rdb 檔案

[[email protected] redis-4.0.11]# mkdir config

[[email protected]

redis-4.0.11]# mkdir data

[[email protected] redis-4.0.11]# cd config/

2.配置 redis master  埠 7000 : 建立 redis_7000.conf

# Redis configuration file master.

#bind 127.0.0.1

####################   埠    #############################

3.配置 redis slave  埠 7001/7002/7003 ...... : 建立 redis_7001.conf/redis_7002.conf/redis_7003.conf  .......

# Redis configuration file slave NO.1.

#bind 127.0.0.1

3.分別啟動  master/slave 的 redis 服務：

[[email protected] redis-4.0.11]# cd src

[[email protected] src]# ./redis-server /home/redis-4.0.11/config/redis_7000.conf

[[email protected] src]# ./redis-server /home/redis-4.0.11/config/redis_7001.conf

[[email protected] src]# ./redis-server /home/redis-4.0.11/config/redis_7002.conf 
 

這樣就啟動好了 redis 主從服務

Step 3：Sentinel 高可用配置

在 config 目錄下建立多個 sentinel.conf 檔案 ：sentinel_26379.conf/sentinel_26380.conf/sentinel_26381.conf ....(埠號不同就行)

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

[[email protected] redis-4.0.11]# cd src

[[email protected] src]# ./redis-sentinel /home/redis-4.0.11/config/sentinel_26379.conf

[[email protected] src]# ./redis-sentinel /home/redis-4.0.11/config/sentinel_26380.conf

[[email protected] 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 裡面同樣需要配置）
